I've worked around 100's of mechanics in my life. Some were naturally mechanically inclined and talented. Others, not so much. Andrew demonstrates extreme mechanical aptitude and creative problem solving to accomplish the task at hand. To accomplish that repair in those conditions by himself was highly impressive. Well done!
Im a mechanic too. I might have put the nuts and bolts in the pick up. It beats chipping them out of the ice . Its easy said when i'm sitting in a nice warm house and you are doing it hard in the icy outdoors. LOL You did well Andrew. That's a nice puller too. merry Christmas to you and your family.
I have to say it again. One of the things that I admire about Andrew is his persistence! I would have given up on replacing that final drive when I couldn't get the old one off without moving heaven and earth. Especially having to work in the muddy slush and freezing temperatures! My hat is off to you, Mr. Camarata!
I'm pretty sure I could have done that repair, given enough time, in a nice, warm shop, with a crane, some repair manuals, lots of good, hot tea and the whole machine cleaned spotlessly before I began. Doing that repair in the wild, parts frozen to the ground and no special tools is the sign of a highly developed human being with endless perseverance and patience. Hats off to another amazing video and the man who not only knows how to use a pipe wrench, but who knows how to edit videos to make them impossible to stop watching. Thanks.

SAY WHAT.. I WAS an M60a1 tanker. I was stationed in Ft. Riley, KS.. Were you..? We were out "in the field".. maybe 4 miles away from the barracks doing mock war games. The dozer dug a big hole for us to hide in.. and when we backed out.. one side spun and the other dug in.. SNAPPING the studs that held the rear sprocket on.. So.. With the weight of the track too.. they winched us back a couple of feet to get access to work on it.. Off came the end connectors first.. We had to stand around you mechanics repaired it. 19E gunner\loader I loved drifting them in the motor pool in winter..

Andrew these sprockets are on a tapered spline and when removing them its best to leave the Nut on enough threads so that when they Pop the dont fly of an cause injury, however your doing a great job, Also you should remove all the paint from any face to face parts as they may probably chatter and become loose causing damage to both the sprocket and the segments
Watching you work in the cold and wet conditions brings back a lot of memories for me clearing land as a young man. When working with heavy machinery you can always count on things not wanting to come off or parts not fitting just right. Thanks for a great video. Best of luck with the rest of this ambitious project,
Andrew, this is why I come and watch your videos. Other channels wouldn’t show the removal of the track they just skip ahead to the thing needing attention. I love to see the struggle and tools/strategies you deploy in the video, it’s what makes you iconic. ✌️ 🛠️
It always amazes me Andrew, just how much you can achieve alone. I have a friend who worked for a farm machinery company in the UK and he regularly went out to Gremany, France, Belgium and many other places to work in the middle of the night to repair broken down or damaged machinery in all weather conditions. My hat is off to you and all who work in those conditions (this coming from a form UK coalminer used to working in bad conditions underground) Take care, Norm in the UK.
I can honestly say that you, Andrew Camarata, are one of the hardest working and one of the most incredibly determined individuals I have ever seen on youtube. You are real, yo show the whole process when things go wrong, and you persevere through it. Bravo sir. This is why I subscribed awhile ago. I first saw your castle building video, and got interested in alot of other things you had going on. You are inspiring. Best of luck in the future! You deserve success in everything you do.
In the 60s I worked my way through engineering school at Penn State as a auto/truck mechanic. I truly enjoyed the work, except in the winter. I hate having to be outside in the freezing cold. My heart went out to you, working on that bulldozer under those conditions. I still shiver thinking about it.
As a mechanical engineer, I love watching your videos. Just seeing how this heavy equipment goes together and how hard it is to work on, is just a real eye-opener and educational experience for me. Thank you also for showing how hard it is to overcome the cold here in NY. People who don't work in the cold don't know how hard it is.
I ordered a sock cap and it comes Friday! That's my Christmas present to myself. I own two of Andrew tshirts and they are heavy quality. I love each and every video. I don't own a bulldozer yet actually enjoyed watching this get repaired. I did feel bad he was working on it out in the cold with no help. I bet he sleeps like a log at night. As always, love watching the dogs. Thanks for the video!

I had forgotten about those O-ring seals that Cat likes to use. In the late 70s I helped with field repair for a Cat dealer. Changing tracks were a pain but relatively easy. Changing sprockets and final drives not so easy. Cat had a puller and installation tools that you could rent that usually came with a hydraulic hand pump and jack similar to a porta-power. As I remember the hand pumps were pretty problematic. I left that world behind in 1980 and never looked back. Cheers Terry
I've done hundreds of final drives on cats, i used to work for Caterpillar, you certainly kept me entertained and scared me a few times. That being said i would certainly work with you in the jungle/desert. Well done and fair play.
I am currently in need of some aftermarket caterpillar sprocket teeth segments and grouser pads. I have same cat d4c hystat dozer. Where did u get these parts from???
This is one of those times when I got chilled just watching Andrew doing this .... in the comfort of my home, I was born into this sort of climate but thank heavens my mother moved us to Australia where I live we don't get weather like this ever..... occasional frosts is about the worst unless we go to the high country for snow 🙂but you could not drag me there with a D8 I'll stay in the warm thank you very much !!
@MW clover leaf - agreed. Tony Beets from show Gold Rush would have been hollering, cussing and shouting at the helper, even though NO helper with Tony. Andrew just works.
Andrew, i’ve been watching the videos for a few years now and you never dissapoint when a new video comes out. You always keep your cool. i don’t seem to keep mine there’s wrenches flying around the room and words that i didnt even know existed coming out of my mouth. I really am impressed with the work you put in and the videos that are produced from you just doing what you do🤙👍
Well done mate .you could not of had the worst weather conditions to work in .Your skill and determination in this repair job was truly great to watch.i think if this was done in the summer you would not have to purchase that hand press ,everything was iced up solid.looking forward to seeing your next challenge.
Andrew, I've watched your channel for years since you were building your castle, and I've always loved how you would tackle any job and often learn how to do it simply by trying.
Andrew, your videos have kept me going through high school, college and now the military. I appreciate your videos so much and I hope you never stop. The first video of your I ever watched was the gray and white dodges, and I haven’t been able to stop since
I wish I could get 1/4 of what you get done but in reality you just have 10x more work ethic than I do so all I can do is respect your willingness to work so hard even when it's hard, cold, you're injured or things get frustrating.
Super enjoyable to watch. Had the privilege of working with a heavy equipment diesel mechanic for a number of years, and your video brought me back. I forgot about all the heavy metal sounds and the talking to yourself. Good stuff kid!
@@troykruse5161 Nah, it's not Andrews channel, it's one of his friends that has videos that also feature Andrew. A bit like Jesse Muller, Dumpster Dave and Samantha Weber have videos that have Andrew in them. Some of them have more of footage of Andrew than others.
As you watch Andrew's videos a lot don't realize how much harder it is to run a D4 than say anything over a D7. It has a short track that can create a roller-coaster effect. The operator feels the front of the dozer going down so he pulls up on the blade. Front of the dozer starts goin up so he pushes the blade down, and on and on. A D8 has a long enough track that it absorbs the bumps and gullies. You don't see that kid ever roller-coaster! He's a good operator!.
Yeah, bigger dozers are much easier to operate than the smaller ones. The longer the tracks make it easier to keep a smooth grade. I used to build fire lines and the longer tracks also have the benefit of not getting stuck as easy. Smaller track dozers can sink in spring heads before you know it. I went to cross a two-foot-wide wash out that was about four feet deep and as soon as my rear sprocket went over the gap the rear of the dozer sank down and I was stuck. It took four other dozers from a D5 to a John Deere 750 to get that little Komatsu D32 out.
I gotta say, I REALLY enjoyed watching that one. Andrew working by himself and never gets rattled or pissed off. And the rare smile at the end was awesome.
Great job, sir. Watching you fix machinery is mesmerizing. You never give up. I love watching you pave your roads with rock you are surface mining. Repurposing it to a better place.
I've never sat and worked in an excavator or similar for a long time myself... but I'm completely enthusiastic about your repair videos. Thanks very much !
Holy cow - the stamina youve got Andrew. I would have thrown things around and cursed a little bit sometimes. I would probably have gotten a cold too, from sweatting and cooling down several times in a row. Good job. 😀
Used to know this old guy who had a shop where he solely replaced tracks and drivetrains on heavy equipment. Heat used to say heat was his best friend… R.I.P. Louie. Probably would’ve just put a relief cut with a torch… as the saying goes… it was broke already. Great job as always Andrew!
Andrew, once again you never seem to disappoint in your videos weather it is a short 37 minute one or an over hour long, in having the knowledge and mind set to address a problem, and fix it, alone and in all kinds of weather, and go back to running and doing what you were doing, like nothing ever happened! Thank you for all your time in getting this dropped and appreciate the sharing. Hugs to Cody and Blue..
Hats off Adam for a fine sprocket hub change out in the field. However in the future Utah track and welding can supply you with everything you will ever need for any and all of your equipment needs. Parts and service.
Hey Andrew.... I can't begin to tell you the number of times I wish I could be there to give you a hand with projects. Damn... I know what it's like doing things by myself, wishing I just had one more set of hands or someone to grab a tool for me. Good lord brother. Keep up the good work... even if it's hard as f.
Andrew, I had to laugh when you installed that seal. That is a toric type seal sometimes referred to a metal to metal seal invented by Caterpillar way back. Instructions on installing that seal was to not touch the finely honed metal sealing surfaces with your fingers. The metal part seals the rotating components and the o-ring keeps the preload on the seal face and seals oil in. Will be interesting to see if it leaks. At Cat we had specs for torquing bolts. The specification was preceeded by the number 1 and the letter E . 1E279 was the torque spec. It covered all grades and sizes of bolts. I guess your spec. was 1Eexcavator. That is a Cat part number on the sprocket....an old number from way back. I own a Cat D3C hystat machine from around 2000. Much easier to service the final drive (planetary) and sprocket. That pressed on sprocket is a beast to work on as you showed in your very nice video. Keep up to awesome content. You are one hard working dude. Haven't see how you broke your foot. Stay safe man.
I chuckled also, mechanical seal should have been replaced. Also all bolts and nuts should have been locktited and torqued. But great repair out in the field with limited resources. If it was me I would revisit my repair in the coming weeks to ensure all was good.
To respectfully ad to or correct your answer. Those are mechanical end face seals. Or as we say in Germany gleitringdichtung. It most certainly was not invented by caterpillar but by George j Cooke for use in compressors, but probably became widespread by Ingersoll Rand in pump operations. Touching with your hand won't cause any problems as long as your hands are clean. The facing surfaces are patterned to allow a tiny amount of oil to travel between to cool and lubricate the facing surface so if dirt gets in it destroys the face. There are many different alloys used for different operations but they are due o the complicated alloys all expensive. The main concern is the pressure load on those kind of seals asto much load means they heat up and burn out to quick and can even act as a break so that a hydro motorbike be exposed to extrem load. I have even seen some big old pumps that drive themselves stuck in a matter of minutes dueto excess pressure load during service. Hopefully that didn't come out too know it allI just thought I should share experience. Keep up the good work guys.
@@Teredifa Interesting. You are correct. It appears Cooke was given credit for inventing the face seal concept for high speed rotating machinery, pumps mainly. The evolution of the face seal and improvements seemed to focus on the high speed application of the face seal for which there were many contributors. Caterpillar's contribution was refining the geometry and metallurgy strictly for slow speed power transmission like track type tractor final drives. Assembly instructions at the factory was to not touch the finely hones metal surfaces and to wipe them with a type of paper at assembly. Early versions of the slow speed face seal had good life but only if you could keep debris out of the interface.
@@hondafrk I wouldn't be surprised if it isn't all that high. It has to make sure the oil doesn't leak out, but most of the power is transferred using the splines, and the nut is held in place by the end cap?
Classic Andrew...after tightening the the nut with 10 tons of excavator...he says "HOW TIGHT DOES THIS HAVE TO BE?" Love it!!!!!!!! Great job Andrew, those were grueling cold and rough conditions to work in...YOU DA MAN BRO! I've never seen a sproket break like that...you need track rock guards for that kind of work I guess.
I have loved watching your videos for years, would be a blast to work with you! One thing I noticed... we always clean the paint off (to bare metal) the wheel before we bolt on the sprocket sections. The paint will desolve in time and your bolts will be loose. Keep working and Merry Christmas!!!
One other tip that I learned from the best boss I ever had... we always broke the master link about 3/4 the way up the sprocket. Made it easier to line up the teeth and reconnect the master link... no clamp needed. Stay safe!!!
CAT engineers will watch this video and come up with designs changes that will make it impossible for guys like Andrew to fix their equipment. Thats why old tractors are always the better engineered equipments. Great guy! Thanks for the content buddy! Just be more careful not to injure yourself champ!
Great video, and really good too see you've got a haul truck that actually hauls without breaking down half way down the mountain!😁 Looks like you'll have alot of rock to crush and build up the road, means more video adventures, that's a win win for us! Merry Christmas and a Happy New Year to you and your family!!😎😎😎
Most impressive to have done this in the freezing cold. And, to do such a tough feat alone - WOW! Thanks for sharing what a real man can do - when necessary. Have enjoyed and learned from your videos for several years. Again, many thanks.
Andrew, you needed to remove all the paint from the new iron before putting the gear segments on, they will work loose over time. The same is said for new pads or rails. Experience is all I will say.
@Eric Trent The nut is usually tightened with a hydraulic "spanner", they have a crazy torque spec. I'm not convinced he got it anywhere near tight enough, but it can't really come loose with the captive cap.
@@einfelder8262 Why do they have such a crazy torque spec? It's not so it won't come loose (the cap takes care of that) and it's not there to transfer power either (the axle splines take care of that). It looks to me all it has to do is seal the oil in and keep the hub from wobbling?
@@paulnieuwkamp8067 If they only drove in a straight line that would be true, but the side loads generated on that sprocket and hub when pushing max weight and turning would be quite high.
@@paulnieuwkamp8067 the torque is required to maintain bearing preload in the final drive as well as the compression on the metal to metal “duo-cone” seal that he left out the first time.
Watching him fix this cat in that weather made me think , what the Tankers went through in WWII in all that harsh weather they had to deal with as well as being under fire just to fix a track or sprocket . Hats off to you Andrew doing a job like this alone well you had the Lab patrol lol.
Andrew, I would like to see a video of you building a 32 x 40 pole barn with steel siding on top of your new mountain. You deserve to be out of the weather.
Andrew, I’m a Kawasaki dealership mechanic. Have you done your KRX transmission recall yet? You have to split the trans and replace a shift fork, 3 springs, one gear and the shift shaft. All covered by Kawasaki. LMK if you need someone that’s done more than 5. Would be fun, and possible content.
It's definitely ruff to work in those cold climates, more props to you Andrew tackling that by yourself 😎👍 had me cracking up at the end of the vid! 😆 🤣 ⚙️
Great job. That was difficult by yourself in freezing wet weather. (But why the heck leave all the parts in the weather overnight to become frozen?!?!?!)
Cat calls those seals a duo cone seal. The outer o rings keep pressure on the metal mating surfaces to stop leaking. Many of the cat dozers have a press fit specification on the sprocket first before putting the nut on. It would require an adapter for the axle threads and a ram with a pressure gauge to read out tons of force. Since it's a small dozer tightening the nut the way you did it might be enough.
I noticed he didn't clean the metal mating surface on the inner hub..... The nut needs to be tightened with a hydraulic "spanner" to something like 5,000-7,000 ft lbs of torque. Maybe for this small dozer it is less, but I don't think he got it anywhere near tight enough.
Andrew the srprocket rim must be pressed on the shaft at a specified tonnage you cannot get the tapered fit tight enough just using the nut !!!! .if you don't do this the sprocket assembly will get loose and spoil the new assembly and the shaft !! You should always remove the paint and clean the mating parts when working on undercarriage. Never stay in front of a press or puller when removing a sprocket they have a lot of energy stored behind them due to the tapered fit and loosen the nut leaving the full thickness of it on the shaft until the sprocket assembly is loose this prevents the assembly from suddenly flying of and injuring someone !!
Andrew, just an FYI that sprocket is to be pressed on with 35 to 40 tons and the nut torque is about 250 ft lbs , I have seen guys do just exactly what you’re doing and what will happen is the sprocket will come loose and you will continue to run it. It will chew up the sprocket just a little bit, and it will damage the shaft, and it will never be able to be tight again without changing all the parts, also when you break a track do it over the sprocket that way your sprocket will align your two pieces.
I am not mechanical side but I take to much interest in mechanical maintance I liked this person very much who do not take any help from other's and personally do it with his brilliant mind.amazing

No pipe used on the pipe wrench when you have an excavator
Having the tools to accomplish the task is where the average joe fails.

I can honestly say that you, Andrew Camarata, are one of the hardest working and one of the most incredibly determined individuals I have ever seen on youtube. You are real, yo show the whole process when things go wrong, and you persevere through it. Bravo sir. This is why I subscribed awhile ago. I first saw your castle building video, and got interested in alot of other things you had going on. You are inspiring. Best of luck in the future! You deserve success in everything you do.
I thought my job was hard. Then I watch Andrew fix heavy FROZEN machines with just pure trial and error. Fucking legend
In the 60s I worked my way through engineering school at Penn State as a auto/truck mechanic. I truly enjoyed the work, except in the winter. I hate having to be outside in the freezing cold. My heart went out to you, working on that bulldozer under those conditions. I still shiver thinking about it.
As a mechanical engineer, I love watching your videos. Just seeing how this heavy equipment goes together and how hard it is to work on, is just a real eye-opener and educational experience for me. Thank you also for showing how hard it is to overcome the cold here in NY. People who don't work in the cold don't know how hard it is.
Plus you know, the "cold" he depicts is absolutely nothing.
Poor, shallow response sir!
I ordered a sock cap and it comes Friday! That's my Christmas present to myself. I own two of Andrew tshirts and they are heavy quality. I love each and every video. I don't own a bulldozer yet actually enjoyed watching this get repaired. I did feel bad he was working on it out in the cold with no help. I bet he sleeps like a log at night. As always, love watching the dogs. Thanks for the video!

This man taught me how to work on small motors. I'm amazed at his patience and so proud of this guy that I first watched fixing lawnmowers build such an impressive business
I had forgotten about those O-ring seals that Cat likes to use. In the late 70s I helped with field repair for a Cat dealer. Changing tracks were a pain but relatively easy. Changing sprockets and final drives not so easy. Cat had a puller and installation tools that you could rent that usually came with a hydraulic hand pump and jack similar to a porta-power. As I remember the hand pumps were pretty problematic.
I left that world behind in 1980 and never looked back.
Cheers
Terry
I've done hundreds of final drives on cats, i used to work for Caterpillar, you certainly kept me entertained and scared me a few times. That being said i would certainly work with you in the jungle/desert. Well done and fair play.
When that drive sprocket popped off like that It was pretty tense. Something that big and heavy flying off like that can easily break a shin or knee.
As a retired heavy Equipment mechanic, I was laughing and crying.
I am currently in need of some aftermarket caterpillar sprocket teeth segments and grouser pads. I have same cat d4c hystat dozer. Where did u get these parts from???
That looked so much hard work in the freezing conditions….respect to you Andrew for getting the job done 👍🏻👍🏻
This is one of those times when I got chilled just watching Andrew doing this .... in the comfort of my home, I was born into this sort of climate but thank heavens my mother moved us to Australia where I live we don't get weather like this ever..... occasional frosts is about the worst unless we go to the high country for snow 🙂but you could not drag me there with a D8 I'll stay in the warm thank you very much !!
Andrew your ambition to tackle the problems at hand brings out your creative ingenuity.
Hell of a job man, be proud of yourself especially in those conditions, definitely pays to have the right tools around you…well done 👏👏👏
@MW clover leaf - agreed. Tony Beets from show Gold Rush would have been hollering, cussing and shouting at the helper, even though NO helper with Tony. Andrew just works.
Andrew, i’ve been watching the videos for a few years now and you never dissapoint when a new video comes out. You always keep your cool. i don’t seem to keep mine there’s wrenches flying around the room and words that i didnt even know existed coming out of my mouth. I really am impressed with the work you put in and the videos that are produced from you just doing what you do🤙👍
Thank you for sharing Andrew. It is nice to see a bulldozer with all of the mudguards in place.😊
Well done mate .you could not of had the worst weather conditions to work in .Your skill and determination in this repair job was truly great to watch.i think if this was done in the summer you would not have to purchase that hand press ,everything was iced up solid.looking forward to seeing your next challenge.
andrew is such a hard worker. his dad must be very proud of him
Ça fait 5 ans que je suis Andrew. Intelligent et très attentionné pour ces chien. Ne crie jamais. Vraiment cool
@@dpaquin58 Je suis d'accord.
@@dpaquin58 Je suis d'accord avec toi. Ca parait qu'il passe beaucoup de temps avec ses chiens.
Andrew, I've watched your channel for years since you were building your castle, and I've always loved how you would tackle any job and often learn how to do it simply by trying.
Andrew, your videos have kept me going through high school, college and now the military. I appreciate your videos so much and I hope you never stop. The first video of your I ever watched was the gray and white dodges, and I haven’t been able to stop since
Thanks for serving our country. You humble me to try to deserve your protection.
I wish I could get 1/4 of what you get done but in reality you just have 10x more work ethic than I do so all I can do is respect your willingness to work so hard even when it's hard, cold, you're injured or things get frustrating.
Super enjoyable to watch. Had the privilege of working with a heavy equipment diesel mechanic for a number of years, and your video brought me back. I forgot about all the heavy metal sounds and the talking to yourself. Good stuff kid!
And that folks is why Andrew is so successful. He does all the maintenance on all his equipment saving him thousands of dollars
I wooda power washed it first
I love watching you fix things. You are on the cutting edge of Shadetree Mechanik.
Hey Andrew....really like the experiences you share on Cerebral Ailments channel.....thanks for sharing with us....🇺🇸🏴
He had another channel?
Check out CerebralAilment on RUclips for more....👍
@@troykruse5161 Nah, it's not Andrews channel, it's one of his friends that has videos that also feature Andrew. A bit like Jesse Muller, Dumpster Dave and Samantha Weber have videos that have Andrew in them. Some of them have more of footage of Andrew than others.
As you watch Andrew's videos a lot don't realize how much harder it is to run a D4 than say anything over a D7. It has a short track that can create a roller-coaster effect. The operator feels the front of the dozer going down so he pulls up on the blade. Front of the dozer starts goin up so he pushes the blade down, and on and on. A D8 has a long enough track that it absorbs the bumps and gullies. You don't see that kid ever roller-coaster! He's a good operator!.
Yeah, bigger dozers are much easier to operate than the smaller ones. The longer the tracks make it easier to keep a smooth grade. I used to build fire lines and the longer tracks also have the benefit of not getting stuck as easy. Smaller track dozers can sink in spring heads before you know it. I went to cross a two-foot-wide wash out that was about four feet deep and as soon as my rear sprocket went over the gap the rear of the dozer sank down and I was stuck. It took four other dozers from a D5 to a John Deere 750 to get that little Komatsu D32 out.
I gotta say, I REALLY enjoyed watching that one. Andrew working by himself and never gets rattled or pissed off. And the rare smile at the end was awesome.
I know , I would have had to "beep" out half my video. ESP in freezing air like dat!
Great job, sir. Watching you fix machinery is mesmerizing. You never give up.
I love watching you pave your roads with rock you are surface mining. Repurposing it to a better place.
I've never sat and worked in an excavator or similar for a long time myself... but I'm completely enthusiastic about your repair videos. Thanks very much !
I don’t know why but I really enjoy watching this guy work and spread rock and gravel.
Wow Andrew, you have more drive, persistence, problem solving ability than any one I've ever known. Kudos
Great display of tenacity working in difficult conditions, what it takes to get the job done...love these videos...
Holy cow - the stamina youve got Andrew. I would have thrown things around and cursed a little bit sometimes.
I would probably have gotten a cold too, from sweatting and cooling down several times in a row.
Good job. 😀
Agree. I would have had a few choice words to say the least.
I imagine he's edited out those parts.
It's a myth ,colds and viruses don't work like that.your welcome.
Used to know this old guy who had a shop where he solely replaced tracks and drivetrains on heavy equipment. Heat used to say heat was his best friend… R.I.P. Louie. Probably would’ve just put a relief cut with a torch… as the saying goes… it was broke already. Great job as always Andrew!
Andrew, once again you never seem to disappoint in your videos weather it is a short 37 minute one or an over hour long, in having the knowledge and mind set to address a problem, and fix it, alone and in all kinds of weather, and go back to running and doing what you were doing, like nothing ever happened! Thank you for all your time in getting this dropped and appreciate the sharing. Hugs to Cody and Blue..
Hats off Adam for a fine sprocket hub change out in the field. However in the future Utah track and welding can supply you with everything you will ever need for any and all of your equipment needs. Parts and service.
Hey Andrew.... I can't begin to tell you the number of times I wish I could be there to give you a hand with projects. Damn... I know what it's like doing things by myself, wishing I just had one more set of hands or someone to grab a tool for me. Good lord brother. Keep up the good work... even if it's hard as f.
I love these repair videos on heavy equipment that he does. What initially got me hooked on the channel years ago
Great video! If you ever find your self breaking tracks again. It’s a lot easier to get the master links back together when you do it over the idler .
Andrew, I had to laugh when you installed that seal. That is a toric type seal sometimes referred to a metal to metal seal invented by Caterpillar way back. Instructions on installing that seal was to not touch the finely honed metal sealing surfaces with your fingers. The metal part seals the rotating components and the o-ring keeps the preload on the seal face and seals oil in. Will be interesting to see if it leaks. At Cat we had specs for torquing bolts. The specification was preceeded by the number 1 and the letter E . 1E279 was the torque spec. It covered all grades and sizes of bolts. I guess your spec. was 1Eexcavator. That is a Cat part number on the sprocket....an old number from way back. I own a Cat D3C hystat machine from around 2000. Much easier to service the final drive (planetary) and sprocket. That pressed on sprocket is a beast to work on as you showed in your very nice video. Keep up to awesome content. You are one hard working dude. Haven't see how you broke your foot. Stay safe man.
Thank you.
I chuckled also, mechanical seal should have been replaced. Also all bolts and nuts should have been locktited and torqued. But great repair out in the field with limited resources. If it was me I would revisit my repair in the coming weeks to ensure all was good.
To respectfully ad to or correct your answer. Those are mechanical end face seals. Or as we say in Germany gleitringdichtung. It most certainly was not invented by caterpillar but by George j Cooke for use in compressors, but probably became widespread by Ingersoll Rand in pump operations. Touching with your hand won't cause any problems as long as your hands are clean. The facing surfaces are patterned to allow a tiny amount of oil to travel between to cool and lubricate the facing surface so if dirt gets in it destroys the face. There are many different alloys used for different operations but they are due o the complicated alloys all expensive. The main concern is the pressure load on those kind of seals asto much load means they heat up and burn out to quick and can even act as a break so that a hydro motorbike be exposed to extrem load. I have even seen some big old pumps that drive themselves stuck in a matter of minutes dueto excess pressure load during service.
Hopefully that didn't come out too know it allI just thought I should share experience. Keep up the good work guys.
@@Teredifa interesting info. Good news here, that one I installed is not leaking
@@Teredifa Interesting. You are correct. It appears Cooke was given credit for inventing the face seal concept for high speed rotating machinery, pumps mainly. The evolution of the face seal and improvements seemed to focus on the high speed application of the face seal for which there were many contributors. Caterpillar's contribution was refining the geometry and metallurgy strictly for slow speed power transmission like track type tractor final drives. Assembly instructions at the factory was to not touch the finely hones metal surfaces and to wipe them with a type of paper at assembly. Early versions of the slow speed face seal had good life but only if you could keep debris out of the interface.
His technique is a little rough around the edges, but his perseverance is undeniable. Nice work!
I mean that's the polite way of saying it
Perfect field repair. Excellent dozer work! The best part of the video is pushing rocks. Everything came together just fine!
That wind sounds brutal, good job under unusual conditions.
Super impressive how Andrew can keep his cool throughout a project like that. Also pretty ingenious using the excavator as a cheater bar lol.
I wonder what the torque spec is supposed to be on that bolt lol
@@hondafrk I wouldn't be surprised if it isn't all that high. It has to make sure the oil doesn't leak out, but most of the power is transferred using the splines, and the nut is held in place by the end cap?
Guessing that the NSFW parts are on the cutting room floor...
@@hondafrk I would guess it to be a 4 foot bucket. 😁
Imagine it was reverse threaded
Classic Andrew...after tightening the the nut with 10 tons of excavator...he says "HOW TIGHT DOES THIS HAVE TO BE?" Love it!!!!!!!! Great job Andrew, those were grueling cold and rough conditions to work in...YOU DA MAN BRO! I've never seen a sproket break like that...you need track rock guards for that kind of work I guess.
Incredible vid. Man against the elements: cold steel, water, ice, mud, snow, freezing temperatures and brute strength. Amazing!
What I love about your channel Andrew is no matter how bad the weather is you just crack on with it great content buddy
As usual…quality craftsmanship and quality entertainment! Thank you, Andrew👌
These maintenance videos are always my favourite.
EPIC. Hard to work in a freezing cold weather but you always do Andrew.

Always impressed with the way you get things done. Working alone requires you to figure out how to make it work. Be as careful as possible.
I have loved watching your videos for years, would be a blast to work with you! One thing I noticed... we always clean the paint off (to bare metal) the wheel before we bolt on the sprocket sections. The paint will desolve in time and your bolts will be loose. Keep working and Merry Christmas!!!
One other tip that I learned from the best boss I ever had... we always broke the master link about 3/4 the way up the sprocket. Made it easier to line up the teeth and reconnect the master link... no clamp needed. Stay safe!!!
CAT engineers will watch this video and come up with designs changes that will make it impossible for guys like Andrew to fix their equipment. Thats why old tractors are always the better engineered equipments. Great guy! Thanks for the content buddy! Just be more careful not to injure yourself champ!
Hey everyone, happy holidays from eastern Washington state. Andrew is my man love his videos.
Great video, and really good too see you've got a haul truck that actually hauls without breaking down half way down the mountain!😁 Looks like you'll have alot of rock to crush and build up the road, means more video adventures, that's a win win for us! Merry Christmas and a Happy New Year to you and your family!!😎😎😎
The Cat and Volvo hauled rock for a while, give it some time, it might take him a week or two and he'll probably break the Bell also.
Most impressive to have done this in the freezing cold. And, to do such a tough feat alone - WOW! Thanks for sharing what a real man can do - when necessary. Have enjoyed and learned from your videos for several years. Again, many thanks.
Happy Birthday Andrew Camarata 🎉 Hope you have many more to come 😊
Thanks
Andrew, you needed to remove all the paint from the new iron before putting the gear segments on, they will work loose over time. The same is said for new pads or rails. Experience is all I will say.
Yes!
@Eric Trent The nut is usually tightened with a hydraulic "spanner", they have a crazy torque spec. I'm not convinced he got it anywhere near tight enough, but it can't really come loose with the captive cap.
@@einfelder8262 Why do they have such a crazy torque spec? It's not so it won't come loose (the cap takes care of that) and it's not there to transfer power either (the axle splines take care of that). It looks to me all it has to do is seal the oil in and keep the hub from wobbling?
@@paulnieuwkamp8067 If they only drove in a straight line that would be true, but the side loads generated on that sprocket and hub when pushing max weight and turning would be quite high.
@@paulnieuwkamp8067 the torque is required to maintain bearing preload in the final drive as well as the compression on the metal to metal “duo-cone” seal that he left out the first time.
Watching him fix this cat in that weather made me think , what the Tankers went through in WWII in all that harsh weather they had to deal with as well as being under fire just to fix a track or sprocket . Hats off to you Andrew doing a job like this alone well you had the Lab patrol lol.
Andrew, I would like to see a video of you building a 32 x 40 pole barn with steel siding on top of your new mountain. You deserve to be out of the weather.
Yes, something with a work area to keep the machines in too, they will rust into the mud up there
the struggle is real!! i love how you never quit. good job andrew
Your unique problem solving ability, perseverance, determination and patience has to saved you hundreds of thousands of dollars !!!
Andrew your videos are so amazing that's a cool bulldozer keep it up
Andrew, I’m a Kawasaki dealership mechanic. Have you done your KRX transmission recall yet? You have to split the trans and replace a shift fork, 3 springs, one gear and the shift shaft. All covered by Kawasaki. LMK if you need someone that’s done more than 5. Would be fun, and possible content.
Can’t wait for the rock crusher videos
Same any time soon ?
Oh yes
Me to
Videos with constant diesel sound are best lulaby for my son. Thanks!
Even so it is very cold you've done what it is needed to fix this machine...thanks so much for that...
It's definitely ruff to work in those cold climates, more props to you Andrew tackling that by yourself 😎👍 had me cracking up at the end of the vid! 😆 🤣 ⚙️
It's always a pleasure to see such talent and skill. Great work!
Great job. That was difficult by yourself in freezing wet weather. (But why the heck leave all the parts in the weather overnight to become frozen?!?!?!)
Andrew never ceases to amaze and entertain!! With brilliance... Love you man....
You-Da-Man Andrew. Your sticktoitivness is amazing.
Props to you working outside in the winter.
Now that I'm older, when it gets below 50°F, all outside activities cease for me!
😂😂😂🌬🌨❄⛄
Cat calls those seals a duo cone seal. The outer o rings keep pressure on the metal mating surfaces to stop leaking. Many of the cat dozers have a press fit specification on the sprocket first before putting the nut on. It would require an adapter for the axle threads and a ram with a pressure gauge to read out tons of force. Since it's a small dozer tightening the nut the way you did it might be enough.
Probably not, 20+ tons ? needed.
@@tomarmstrong4156 This is what I came to the Comments for; Can you guys jump in some more. I think everyone, including Andrew would appreciate it.
I noticed he didn't clean the metal mating surface on the inner hub..... The nut needs to be tightened with a hydraulic "spanner" to something like 5,000-7,000 ft lbs of torque. Maybe for this small dozer it is less, but I don't think he got it anywhere near tight enough.
Andrew the srprocket rim must be pressed on the shaft at a specified tonnage you cannot get the tapered fit tight enough just using the nut !!!! .if you don't do this the sprocket assembly will get loose and spoil the new assembly and the shaft !!
You should always remove the paint and clean the mating parts when working on undercarriage.
Never stay in front of a press or puller when removing a sprocket they have a lot of energy stored behind them due to the tapered fit and loosen the nut leaving the full thickness of it on the shaft until the sprocket assembly is loose this prevents the assembly from suddenly flying of and injuring someone !!
Andrew, just an FYI that sprocket is to be pressed on with 35 to 40 tons and the nut torque is about 250 ft lbs , I have seen guys do just exactly what you’re doing and what will happen is the sprocket will come loose and you will continue to run it. It will chew up the sprocket just a little bit, and it will damage the shaft, and it will never be able to be tight again without changing all the parts, also when you break a track do it over the sprocket that way your sprocket will align your two pieces.
And he used an old seal instead of a new one after all that work
Not to mention that leaving the paint on the sprocket might very well allow the segments to loosen.
11:38 - Ouch! That looked like that would've hurt! And then immediately jumping on the oil. Impressive buddy!
I am not mechanical side but I take to much interest in mechanical maintance I liked this person very much who do not take any help from other's and personally do it with his brilliant mind.amazing
Ide say he will save the rock crusher video for Christmas Day. Its going to be brilliant.
Imagine a 2 hour video of rock crushing on Christmas day!!
Good advice: before tightening the bolts, you need to anoint them with graphite grease. In the future it will be easier to unscrew
Good advice for those of us who don't have an excavator handy to loosen bolts.
I was thinking that, I’ve never seen him grease a bolt?
@@____________________________.x Sometimes grease :)
I am looking forward to this Andrew! 👍
Great video. Any man that can use a clamp like that and make it work deserves a beer in my books. Awsome!
I am envious of how calm you can remain when stuff breaks or just won't cooperate! 🤣
😂😂
