@@KT3406Ehey mate this popped up today so clicked on it, realised I've seen before but watched again as I enjoyed it so much first time, so your work and the 3days of editing was much appreciated thanks
This is absolutely the best mix of talking about stuff, doing stuff, explaining stuff, and skipping stuff that exists in “social entertainment” today. Absolutely the best without question. Thank you.
I watched the entire 2 hrs and 10 minutes. If you were...say 75 years old and had worked as a CAT mechanic for 55 years, I could understand your level of expertise on just about everything CAT. I've seen all of your videos and each one leaves me wondering how the heck you learned so much in such a short time. OK...I'll call it a "gift" and be grateful that you continue to produce videos to show the rest of us how it's done. Many thanks.
Many people start very young with hands-on work which is the best way to learn, and some just have a special gift for learning specific things! Also there's a lot of information on the interwebs to learn from today, you just gotta sort through it to find the good stuff! 👍🏻👌🏻🛠️🔧🔩🚜🦺🚧 ✊🏻🇺🇸🦅🇺🇸✊🏻
I am an old shade tree mechanic, and always learn about 10 tricks from every one of his videos. simply the best. I hope every diesel training school in the USA is using his videos. I also appreciate his use of safety equipment. His analysis of wear and damage is spot-on.
Myself and three others designed the first DJB articulated truck which was eventually bought out by Caterpillar. The D400E was the last of the side cab "swing axle" front suspension trucks Going from a 3306T to a 3406TA was a big step for us, but one we never regretted. We also made a 55t truck with a 3408T, mmmm, not so good! I really enjoy these videos especially those featuring our articulated trucks.
We rebuilt a Cat D-9G engine in the field at Meshberger Stone in Columbus, Indiana quarry in the late 60's. I wish we would have had a guy like this to help us. Unbelievably careful attention to detail. KT3406E best mechanic I've ever seen.
You must be the same guy at the TA truckstop in Corning, CA about 35 years ago who fell asleep on the shitter and woke up screaming he couldn't feel his legs. Funniest damn thing I ever saw and heard. I damn near couldn't eat I laughed so hard.
Great to see you back. I'm a postman from Scotland and know nothing about CAT diesels, but I've watched every one of your videos. The Knowledge and skill you have combined with your laconic wit is brilliant to watch. Thank you for sharing these videos with us.
I love how all of this video is just full of common sense no half ass repairs even for the overall content to be a half ass attempt in frame. Thanks for talking to the camera as much as you did it’s nice to learn from the experts who know what they’re doing. There’s those of us that will gladly sit and listen through it all. I learned a lot in this vid thanks for the ride along and the lessons.
Love your stock pile of parts. Retired now but when I worked on the floor and eventually managed the place, my younger techs would laugh at my stock pile of "junk" they called it I had upstairs and in the storage sheds. Didn't take long for them to figure out just how good the "junk" was till they had to use it. Having some older trucks in the fleet or an old customer with a "classic" truck that needed something that was too expensive new, or even a parts shortage going on, that " junk" kept everyone working and the wheels rolling. I like the term "good used" as you say it. Excellent video by the way and one of the best engine break in procedures and engine brake test too.
Glad you are back . My Grand pa had a bone yard in the woods on his farm , Lots of old chevys he got drunk and crashed and crashed running from the law . He would take a torch there and cut 2 or 3 chevy small blocks out of them and bring to his garage and I would help , He would Tear them all down and pick the best parts and build a engine for his old truck . He would get 100k mi out of it and then do it again and again each time it blew up . He drove that old truck till the day he died . You reminded me of him building that engin and making it work I sure miss him . Thank you .
Watched for the second time, can't get enough and can't stop laughing. "You put the lube on the bolt. You smear it around. You take the bolt. Stick it in a hole and you spin it. Very exciting." You kill me brother.
I am not a mechanic but I am a long time trucker and the 3406E is far and away my favorite engine... and I've experienced MANY engines. Enough of that, this content is so incredibly, (and unbelievably), relaxing and enjoyable to watch. I totally understand how the content provider doesn't quite grasp why we keep coming back... but we do! For me, this is what RUclips is all about.
Can’t believe I just spent 2hour 9 mins and 52 seconds. Watching someone turn a few wrenches on an old cat motor could ever be so entertaining. JB-weld needs to sponsor this man.
Man I was hoping and praying you hadn't retired. Love your content. I'm coming off the road in about 5 years, and all I plan on doing is rebuilding CATS. 👌🏽✌🏽👍🏽
This is an epic video. I've watched smaller stuff on other channels (Caterpillar D2 rebuild, etc.) but this mammoth effort (days or weeks of work condensed into 2 hours for our viewing pleasure) brings intimate awareness of Cat heavy haul powertrains to the average viewer. KT3406E you are truly a legend. All respect for your skills and knowledge and kudos for the excellent videography the entire time, I know how much effort it adds to any project. Thank you, sir.
I really appreciate the common sense approach to rebuilding an engine using what you can reuse and only replacing what is needed. Your comment is always very informative and no fluff. Looks like a good useable haul truck. Thanks for the videos.
I love watching your videos, because I imagine I'm there the entire time in the garage...sitting in a chair talking to ya while you talk to the camera. Garage workshop conversations are some of the best.-
I am not a mechanic and I don’t know anything except for this whole video was somehow fascinating! Amazing to learn a little bit of how things work! Well done
7:16, 1:27:55 For anyone wondering why those cam gears have rollers in them: these rollers function as what's known as a _centrifugal pendulum absorber._ These devices are a tuned system where the resonant frequency is always some constant multiple of the rotational speed (that constant multiple is known as the _order_ of the system). For an inline-6 engine, the torsional excitation which the camshaft experiences is always six times its rotational speed, so an absorber on the camshaft would be tuned to the 6th order. Though, practical absorbers are always slightly overtuned (i.e. the actual tuned order is slightly higher than ideal), due to limitations imposed by transmissibility and stability. The path that the weights travel on also matters a lot. For smaller applications, a circular path is sufficient, which is what you're seeing in that cam gear. But circular path absorbers suffer from a problem where the system's tuned order will decrease as the amplitude increases (specifically, the tuned order at 180° of swing is 15.2% lower than at 0° of swing), and if the weights move too much, the absorber can become unstable and actually _amplify_ vibrations instead of suppressing them. If this happens, you then need to decrease the engine speed to restore the system's stability, often to a speed which is a lot slower than that where the system destabilised in the first place. Circular path absorbers are typically overtuned significantly (at least 20% or so) to prevent them from becoming undertuned (which is where they risk becoming unstable), while larger absorbers typically employ epicycloidal paths so that the tuned order is the same regardless of how much the weights swing. Also common on larger absorbers are bifilar (two-point) suspensions, which enable the use of larger and heavier weights than simple roller-type systems, which decreases the required amplitude of motion. Newer engines are taking this a few steps further and putting pendulum absorbers directly in the powertrain. In an even-fire 4-stroke engine with N cylinders, the dominant excitations on the crankshaft are those of the N/2 and N orders. People in academia are even experimenting with multi-order systems where the system consists of two or more sets of absorbers of different orders which are attached or connected to each other (on a 4-stroke engine, one set of weights tuned to the N/2 order, and the other tuned to the N order). In practice, I see putting these things on single-mass flywheels as a great alternative to dual-mass flywheels.
I can see why you have 180k subscribers, that was an excellent video being both interesting and educational for me. You seem to get the balance just right with what to show and what to simply mention so it doesn’t become a boring “how to” video. Being extremely knowledgeable in your field not only helps you but helps the viewer understand what is right and wrong on the machine. I’m so glad you found that missing plug or you would be right back where you started in no time. Cheers, Stuart 🇦🇺
I did a double take when I saw KT3406E 2 hour video in my feed! I am going to set aside some prime time to watch my favorite mechanic rebuild my very favorite engine! Now I must gather some cold beverages and snacks and put my phone on mute!
I very rarely or ever comment on you tube videos. Your channel is my favorite of all the subscribers I have. I know zero about diesel engines. The internal parts just amaze me. I love your content, your knowledge & quality is top knotch. I keep watching re runs of videos I seen already still good. Keep up the great work !
I am not a diesel mechanic, but used to operate heavy equipment for 12 years. I work on gas engines and repair my one cars. I’m amazed with the mechanical ability this guy has and explains everything as it goes along. Amazing videos thank you!
Thank you for showing the rolling in of the main bearing. Heard about this, people just say "roll them in", but never seen the bolt / grease used nor how it was actually done. NEAT!!!
Your mechanical knowledge is only matched by your dry wit and humour. I fucking love it, I wouldn’t stay subscribed with this long between videos with out, thank you sir
Watched while rebuilding my single cylinder Toro, now I am convinced I can overhaul a Cat haul truck you made it look so easy. Great video and a master of the wrench.
Just found you a few weeks ago. Glad to see someone your age with go to, git it done attitude, and common sense. Keep up your great work and videos, I’ll keep watching.
Sure have missed your videos. Thanks for not forgetting us and not being scared to throw us a nice long video like 95% of other creators appear to be terrified to do. Cheers brother.
Great video. I enjoy seeing a pro at work. I used to operate one of those D-400 trucks at a Coal Prep Plant back in the mid 1990's. We had 2 of them that we used to haul mud that was washed off the coal up a mountain to a refuse area. Our trucks had tail gates that would swing up by chains when we raised our beds. They had welded 18 inch side boards down both sides of the bed so we could get more mud on them without it sloshing out. We had 3 - Cat 777's that would haul the rock that was separated from the coal up to the same refuse area. There a D7N would have a trench dug for us to dump the mud into then a 777 dumped about 90 tons of crushed rock on top of the mud and the D7 would mix it up some. When that stuff dried out a few days it was like concrete.
This was the best $380 rebuild I've ever seen on any engine! And you are very correct in not throwing a lot of coin at this engine knowing the rest of the drivetrain is not in the best shape.
I love this video. You always see videos of complete engine rebuilds new and machined everything. This video proves that you dont need a factory spec rebuild to make it work for another 10000 hours.
20:40 goes without saying, but THANK YOU for pulling liners with hand tools… absolute turbo genius coworker went to town with an impact on the shop liner puller and mangled all the threads last month
I can appreciate a good mechanic that doesn't make assumptions based on past hear say problems that another mechanic experienced. Its not always the brand name that makes parts go bad.
Always love your videos! Have watched your videos for years. You’re a LEGEND for sure! Always impressive whatever builds are. I’m 70 years old and totally enjoy your skill set. Ronnie East, Tennessee
I was thinking some kind of line bore chamfer refresher cutter. You could make one pretty easy. Then just hook it up to your Milwaukee 1/2” and run it slow under its own weight two or three turns and you’d be good. I’d love to see it done.
@Flyanb That unfortunately would not even come close. There is a large amount of material that has to be removed to remove all the damage, and then an insert has to be put in to replace it.
@@KT3406E i would have just used the epoxy too. We have an iron filled epoxy that we use for foundry tooling that is tough as nails, tolerates high heat and expands similarly to the ductile iron cast block. I bet that’s the ticket! I suppose if it comes out and gets in the oiling system it’s so small it’s like bearing or other metal shavings you don’t want a lot but a little won’t wreck your day
I'll probably never do this kind of work on one of these, since they're not that plentiful here in Sweden. But that don't make this video any less interesting. Your knowledge of these engines is awesome. Insane, but still awesome. Good to see you're back in action here on RUclips 💪🏼. Always educational, always something to learn.
It's amazing how many of these errors in the previous rebuild that he points out in the video are things that I see as a very amateur mechanic and say "How did they miss that?" The total apathy and/or stupidity some "professional" people have is truly mind-boggling. The extra fuel filter really got me. lol
At first I thought the issues with the engine was an oiling issue. Which was seemingly "confirmed" by the incorrect oil pump pressure relief valve spring tension setting. Only to find out that the real culprit was unfiltered air. Seems like the airstream carried the majority of abrasive particles directly to Cylinder No 3. But all in all, it was quite interesting and satisfying to watch the teardown and rebuild. Thank you for sharing this video with us! 👍
My dad and his friend used to own a sandpit back in the 80s. When I was a kid, I was put to work there loading trucks on a front end loader and running a track hoe in between. I had to replace the occasional busted hydraulic line and maintain the machines daily during operation. Never in the weeds mechanically like you do here. I haven't been around that work in many years. Your videos are quite informative and you obviously have a lot of knowledge at such a young age. I never knew there was this much to a piece of machinery aside from the limited work I did on the machines. I am really drawn to your ethics on repair and the willingness to do the job right. That is the most impressive part of your videos to me. You do an excellent job at keeping your shop neat and clean so you can work. I also like the fact that you keep those cores around to use on other repairs. This makes it affordable for the smaller operators to cover the cost of those repairs. I know it is time consuming recording and editing out videos. You would be surprised at how many people enjoy watching things like this. Nice to watch when you need a relaxed moment.
Awesome video, i watched it 3-4+am, Love how you figured out about the bad cylinders because the 2 holes were not plugged & dirt entered through the holes also the bolts need changing except the 1 that allows oil through it, sooooo NO these videos are NOT BORING, your the BEST😅
In my opinion this is a fine example of how you can achieve doing the wrong things the CORRECT way if done properly like this young man has done so .. One must respect how he has taken the time to explain and show in full detail how you can do these thing correctly on a budget and cutting corners BUUT the correct way..Absolutely perfect well executed and beautiful done !!!! 🤙

@@kd5byb Ah, you're pretty well educated now, didn't think I would watch every minute but I did, a real gem at 53:00
This guys good at what he does, and he’s funny. One of the best channels rn
Your mechanical knowledge is only matched by your dry wit and humour. I fucking love it, I wouldn’t stay subscribed with this long between videos with out, thank you sir
I'm no diesel mechanic but stayed for the entire ride. You have some real skillz! And great camera work & editing too!
KT your mechanical competence and dry humor are top drawer… have missed your videos
Watched while rebuilding my single cylinder Toro, now I am convinced I can overhaul a Cat haul truck you made it look so easy. Great video and a master of the wrench.
Welcome back KT and thanks for making a great Sunday!
Just found you a few weeks ago. Glad to see someone your age with go to, git it done attitude, and common sense. Keep up your great work and videos, I’ll keep watching.
This man knows his sh-t and has the get er done spirit.
This is impressive! I had no idea that it was even possible to do a rebuild without taking the engine out. Congratulations on a great project.
Sure have missed your videos. Thanks for not forgetting us and not being scared to throw us a nice long video like 95% of other creators appear to be terrified to do. Cheers brother.
Great video. I enjoy seeing a pro at work. I used to operate one of those D-400 trucks at a Coal Prep Plant back in the mid 1990's. We had 2 of them that we used to haul mud that was washed off the coal up a mountain to a refuse area. Our trucks had tail gates that would swing up by chains when we raised our beds. They had welded 18 inch side boards down both sides of the bed so we could get more mud on them without it sloshing out.
We had 3 - Cat 777's that would haul the rock that was separated from the coal up to the same refuse area. There a D7N would have a trench dug for us to dump the mud into then a 777 dumped about 90 tons of crushed rock on top of the mud and the D7 would mix it up some. When that stuff dried out a few days it was like concrete.
Glad to see him back. Always a clear concise explanation in easy to understand common language !
I never sit still for a 2 hour video. Except these. As always, with the wait
This was the best $380 rebuild I've ever seen on any engine! And you are very correct in not throwing a lot of coin at this engine knowing the rest of the drivetrain is not in the best shape.
"Daily rents worth rebuild"
I love this video. You always see videos of complete engine rebuilds new and machined everything. This video proves that you dont need a factory spec rebuild to make it work for another 10000 hours.
20:40 goes without saying, but THANK YOU for pulling liners with hand tools… absolute turbo genius coworker went to town with an impact on the shop liner puller and mangled all the threads last month
Watched the entire video. I have no experience working on diesel engines, but wow you make it so interesting! thank you.
That is flippin great man!! You have the wisdom and experience of a 200 year old man. God bless!
Thanks for taking the time to both record and narrate a great video. Awesome
I’m no mechanic by any means but your videos fascinate me. Your attention to detail and your mechanical knowledge is brilliant. Well done.
Hi, at first, I thought +2h was abused, but I watched it entirely - it is always a great pleasure to watch a man of the art working thoroughly. :)
Glad you're back. You should do videos more often, please.
I can appreciate a good mechanic that doesn't make assumptions based on past hear say problems that another mechanic experienced. Its not always the brand name that makes parts go bad.
Always love your videos! Have watched your videos for years. You’re a LEGEND for sure! Always impressive whatever builds are. I’m 70 years old and totally enjoy your skill set. Ronnie East, Tennessee
Thank you for posting again, I found myself watching old videos again and again 😂
You should be teaching this to young men at a tech school witch we know so much.your a genius, waited 8 months, love your channel
I know I’ll never rebuild a heavy equipment engine but I like watching any type of engine repair or rebuild video. New subscriber here now.
In Mississippi we have a machinist who can repair lower bores with the motor still in the frame. He has saved us multiple times over the years.
I was thinking some kind of line bore chamfer refresher cutter. You could make one pretty easy. Then just hook it up to your Milwaukee 1/2” and run it slow under its own weight two or three turns and you’d be good. I’d love to see it done.
I'd like to see that setup! Very cool.
I'm sure I've heard of this been done without removing the engine
@Flyanb That unfortunately would not even come close. There is a large amount of material that has to be removed to remove all the damage, and then an insert has to be put in to replace it.
@@KT3406E i would have just used the epoxy too. We have an iron filled epoxy that we use for foundry tooling that is tough as nails, tolerates high heat and expands similarly to the ductile iron cast block. I bet that’s the ticket! I suppose if it comes out and gets in the oiling system it’s so small it’s like bearing or other metal shavings you don’t want a lot but a little won’t wreck your day
Best two hours I have spent at work in a long time. Great content KT!
I'll probably never do this kind of work on one of these, since they're not that plentiful here in Sweden.
But that don't make this video any less interesting.
Your knowledge of these engines is awesome. Insane, but still awesome.
Good to see you're back in action here on RUclips 💪🏼.
Always educational, always something to learn.
Your good old R5, R6 Scania or Volvo is not that different. Get on it!
It's amazing how many of these errors in the previous rebuild that he points out in the video are things that I see as a very amateur mechanic and say "How did they miss that?" The total apathy and/or stupidity some "professional" people have is truly mind-boggling. The extra fuel filter really got me. lol
At first I thought the issues with the engine was an oiling issue.
Which was seemingly "confirmed" by the incorrect oil pump pressure relief valve spring tension setting.
Only to find out that the real culprit was unfiltered air.
Seems like the airstream carried the majority of abrasive particles directly to Cylinder No 3.
But all in all, it was quite interesting and satisfying to watch the teardown and rebuild.
Thank you for sharing this video with us! 👍
Excellent observation and proof of why you need good air filters on any engine.
My dad and his friend used to own a sandpit back in the 80s. When I was a kid, I was put to work there loading trucks on a front end loader and running a track hoe in between. I had to replace the occasional busted hydraulic line and maintain the machines daily during operation. Never in the weeds mechanically like you do here. I haven't been around that work in many years. Your videos are quite informative and you obviously have a lot of knowledge at such a young age. I never knew there was this much to a piece of machinery aside from the limited work I did on the machines. I am really drawn to your ethics on repair and the willingness to do the job right. That is the most impressive part of your videos to me. You do an excellent job at keeping your shop neat and clean so you can work. I also like the fact that you keep those cores around to use on other repairs. This makes it affordable for the smaller operators to cover the cost of those repairs. I know it is time consuming recording and editing out videos. You would be surprised at how many people enjoy watching things like this. Nice to watch when you need a relaxed moment.
I could honestly watch your videos all day, like today for instance. The simplicity and amount of information is incredible.
To my surprise while on a much needed vacation, a 2 hour video of the best Sahara-esk dry sarcasm that I so enjoy.
The ECM is fuel cooled? Well you learn something new everyday!
I learned more about CAT engines over the last 2 hours than I did the last 2 years. Thank You!
What a fine surprise this sunday morn, glad to see all is well!
Awesome video, i watched it 3-4+am, Love how you figured out about the bad cylinders because the 2 holes were not plugged & dirt entered through the holes also the bolts need changing except the 1 that allows oil through it, sooooo NO these videos are NOT BORING, your the BEST😅
Probably the best video I have seen this year , fantastic
Agreed.
this guy never fails to amaze me! been gone for month's and brings us a 2 hour beauty🥰
I swear to god if I have to wait another 8 months for another video i'd be ok with that lol, top notch as always!!
Deadly video Sir, i watched it twice
Thank you, this was better than any movie I have ever watched !!!
In my opinion this is a fine example of how you can achieve doing the wrong things the CORRECT way if done properly like this young man has done so .. One must respect how he has taken the time to explain and show in full detail how you can do these thing correctly on a budget and cutting corners BUUT the correct way..Absolutely perfect well executed and beautiful done !!!! 🤙
