REBUILDING A $2,000 CLAPPED OUT EXCAVATOR... DOESNT GO AS PLANNED..
HTML-код
- Опубликовано: 6 июл 2024
- THIS IS PART 2 OF SAVING THIS NISSAN/HANIX N150-2 MINI EXCAVATOR. THIS MACHINE IS IN VERY BAD SHAPE AND HAS SEEN ALOT OF HARD USE, WHICH IS MAKING IT VERY EXPENSIVE TO REPAIR. IN THIS VIDEO WE REBUILD ALL HYDRAULIC CYLINDERS, INSTALL A NEW SLEW PIVOT VALVE, AND REMOVE THE SLEW MOTOR AND BEARING WHICH ARE BOTH COMPLETELY DESTROYED!!

Just wanted to thank everyone for checking out my video! I appreciate everyone of you!
try to contact "this old tony" he could inform you or help you out
You are very talented. Thx for sharing. Dog in front of the fan was 😊 fun.
There are machine shop companies on the web that can make a pinion for you or a thousand pinions for you. You fill out one of their forms or send some kind of blueprint file to them and they get back to you with an estimate. You can also check out and contact the you tube machinist community and see if they would take on the job. i like Abom 79 and I think he could help you out. Another option is maybe you might learn machining and acquire a lathe with some tooling, a dividing head, a shaper, some metrology tools, and a heat treat oven. With some time, learning and research, you can take pride in saying " I made it myself".
@@MichaelNaurock yes I’ve checked with those companies they will only do a $4500 minimum, I know how to machine I just need the funds and a bigger shop to house a lathe..ect. I have decided I’m probably going to fix the gear myself, I’ve done it before I’m just more iffy on this job because excavators can put a lot of pressure on those pinion gears
@@TheHomePros6221ive had the same swing motor and a similar excavator what's a lot of the same problems I had a local machine shop cut the swing gear did they cut the wood for $1,000 it took me about a year to figure and get this all straightened out but it works great
Very sorry that you had to uncover more mechanical failures but extremely impressive to watch you go through this methodically, and with supreme mechanical understanding
Thank you very much my friend!
I am 65 and have been a back yard mechanic my whole life... my current project old flhri rk is broken. I love to work with my hands and fix things, You in my opinion are best back yard mechanic I have EVER had the pleasure to watch. I love your calm demeanor which is a must when trying to fix old broken stuff with no directions, shop manuals or the proper tools. There are 5-6 folks I watch here and now you are #7.
Thank you for taking the time to video all of the repairs you make.
Blessings
I can't believe you don't have more subscribers, definitely one of my favorites.
Contact Farmcraft101 or OnFire Welding
He did have until he got hacked now trying to build it back to where it was I will watch everything he put out from here on to support him
@@deannelson9301 I don’t think John can cut splined gears he just has a lathe, and on fire welding doesn’t either
@@bmexcavation957 thanks brother!
I do have a similar machine and i could not find the shaft as well.... to have it repaired would have been £500... too expensive. Mine it's a MOD 5, 13 teeth, 70 mm diameter gear end ⚙️ . As a temporary measure i decided to have it pressed out and i welded it myself, i used E6018 electrodes (didn't have E7018), turned to diameter in my lathe so ia had better grinding reference as i did it with an angle grinder by hand, no issues so far used it for 20h now.
When i have time i will inspect it, if it's bad i planned to turn the teeth off and make a keyway and press a gear which i already purchased for £40.
Props man, I kinda can't believe you took that so far apart in your frickin driveway man, props. Best RUclips of the month
@@josephcarino5829 lol thanks man! I really appreciate it!!
Your abilities and calm demeanor while you locate and explain the issues you uncover with this old and abused equipment is such a pleasure to watch and learn from. Your skills and patience while you take the time to carefully document/video/explain the process is absolutely one of the best on any platform and all while outside without the fancy shop tools that most would need to accomplish what you do! Thank you so much for taking all the extra time videoing to allow us to come along on your projects. Be well.../B
@@bobbalbirnie2478 aw thanks man that really means a lot! It takes me a long time to film and edit so it means a lot when viewers appreciate the hard work that goes into making the videos so thanks again!
Sir, i could tell immediately the effort you have gone to filming this project. As has been said above you are very good with explaining the process of fixing things, a bit like Snowball engineering does in his films of mending farm machinery . All the best from England.
“…I wasn’t going to replace this, but I decided to do it anyway.” How many times do I wish I’d taken your approach. Great work!
Lol thanks! I’ve learned that’s it’s best to check if you have any suspicions, instead of having to go back and tear everything back apart to fix it later😊
Hey I resemble that remark! 😁😆🤣
For the pinion gear, you might want to reach out to some of the machinists on RUclips like Abom79 (in Fla) or Steve Summers (in Ky?). I know Abom79 has a big shaper that could cut those teeth and they both would know what type of rod to weld it back up with and what the process would entail.
I hope your comment gets noticed!
Good call 👌
Steve Summers would be able to make you a new one, or he may be able to advise you on how to fix it.
You've spent some time and money on that worn-out thing, but it'll be usable when you get it finished.
Thanks for the video, and God bless you!
Keith Rucker from vintage machinery is another option.
Wow, I've never seen anyone go to town on a tear down/ rebuild like this. As you're unfortunately finding out, that machine has obviously had a rough time in its past, and hasn't had a lot of love.
One thing Darrell, it'll be a top notch machine when you're done, as no stone is being left unturned, and nothing left to chance. Love your patient, methodical approach, makes your videos very watchable .
Keep going buddy.....I'm sure everyone is already looking forward to part three.., I know I am...😊👍
thank you very much dave! I really appreciate that!!
Sir you have the patience of an Angel , that was a lot of work in this video , can't wait for the next part !
This old 92 year old West Texas guy enjoys all your videos,, yours and Diesel Creek's. Keep 'em comin'.......
Who's the first president you remember as a kid?
You should check out Northwest Pacific Hillbilly.
You'll want to go back to his Cat D4 restoration then watch his Excavator restoration.
He's incredibly good to watch.
Also check out Watch Wes Work.
He's really entertaining to watch.
@@khbow thank you!
Great video. No drama. Just fixing.
Your dog is the smartest one in this group! 🙂 You really picked a tough one this time but it looks like you're killing it. Good job and thank you for sharing.
@@richardcorwin1828 thank you!! I appreciate it my friend!
MM77 Approved 👍🏼 👍🏼…………………………………………………………………………..Well, you can look on the bright side, you have some great content AND if you can get the shaft fixed or where to find a new one you will have a new old stock machine that you know every inch of !
thanks man! yes one good thing about tearing somthing apart like this is that you know the condition of the entire machine and have peace of mind that everything is done rite, it’s kinda like starting fresh with a new machine. thank you for watching my friend!!
It’s crazy how someone had enough brains to tear into that thing to some extent but not enough to put it back together right.
they didnt care.
I know rite!! I mean I know it’s very expensive to take stuff to dealers…ect and people want to fix their own stuff like I do, but at least they could have gotten a service manual and did it rite step by step and actually tightened the bolts down lol.. crazy stuff man. Hope all is well with you brother! Glad to see you posting videos as well
Once done that is going to be a cracking little digger ! Stick in you will get it done.
Zen and the art of excavator mechanics. You have extreme patience and perseverance. Love your production but at several stages I felt like poking myself in the eyes. after being a mechanic for 50+ yrs part of the enjoyment is watching you go through it, I am reliving past experiences, thank you for your hard work.
Thanks 👍 that means a lot my friend😊
On the bright side, tearing the machine down to this level to replace things should give the machine a nice long life. I have also never seen an excavator torn down this far so it has been very interesting to actually see the different motors and gears as you went on. Thank you for sharing this experience with us!
@@mrdwets8952 thanks! Glad you enjoyed the vid
New viewer here I was amazed to see no hydro fluid come out of anywhere! That’s a project and a half that I would have never attempted or given up on at the discovery of the broken tooth in the slew kudos to you, I’m glad it’s you and not me but thanks for doing this for my knowledge that I’ll never use but glad to know how that thing comes apart! Great video
@@fredschneider4036 welcome my friend! Glad you enjoyed the vid!!
Well done as always my friend. Thanks for sharing, and god bless you.
@@lottiecooper609 thank you!!
I bought a overly used Hanix NO802. Original engine was swapped out to a 10hp Honda. I had 3 cylinders fixed, I replaced bushing & Pins on boom, dipper, bucket and King Pin. New oil and hydraulic screen looked to have never been cleaned. Workable and better than hand digging with a shovel.
@@r1mein54 nice! Thanks for sharing I love hearing stories like that!
@@r1mein54 so that’s a size or two smaller than mine, or basically like the size of my other ihi 9vx-3 mini
Thanks for posting! Bummer about that slew gear bearing, you are really taking that thing down to its bones 🦴
Man you have a lot more determination than I do, really good work 😊👍
thank you very much mike! I always appreciate your comment! 😊
Great video,
regarding the gear
a Hanix H15, Hitachi ZX16 (010300A) should have a very similar slew bearing and a similar gear. Unfortunately this does not fit the hydraulic motor. Instead of re-welding the teeth, I would get a new gear from the H15 and weld them together in the bearing area. With sufficient cooling, there should be no problems with hardness and the teeth are correctly shaped. To get the alignment right, I would do it on a lathe.
Best regards from Germany & keep up the great work
Gidday Darrell, I’m a recent subscriber and I’m really enjoying the content you put in your vlog, your attention to detail is awesome and it’s great that in your builds you investigate problems until you find the root cause as it saves a repeat performance. I’m working through the back log on your channel and there’s some interesting and varied subject, good to see you have a crack yourself. Enjoying this particular rebuild as it’s what got me into your channel, I remember when I started my own farm I often bought old pieces of machinery, some even garden art, and rebuilt it over time but it was what it was and keep me moving forward although I don’t think I had your patience. I can see down the track a lathe and mill will be necessary kit in your workshop. Well done, great channel.
welcome my friend! and thank you very much I really appreciate it!
From all you are uncovering it looks like the previous owner had opened everything up like you did, found the bad teeth on the gear and swing bearing (and so much more wrong), decided to put it all back together, and not really tightened everything back up knowing he was going to sell it. Did a quick paint job and then listed it on FB marketplace. However you are a trooper and not given up. I am very happy that you are going to continue to work on the excavator. It's very possible that the excavator was used beyond it's recommended strength....in other words "Rode hard, put up wet" It will be an awesome machine once repaired. Keep up the good work and thanks for the long videos...we actually like the long videos. Take care!
Great job again Darrel and I look forward to part 3 of this rebuild. You’re one of the few channels on uTube that I can watch for an hour or more. Keep up the good work!!
thanks William! that means a lot
I am enjoying this rebuild. I found out years ago, buying something cheap ends up costing as much or sometimes even more than buying the same thing in mint condition and perfect running order.
@@ianallen2 thanks! Sometimes that’s the case but a lot of times I get cheap stuff that’s cheap to fix
This is the only channel on which I can thoroughly enjoy hour-long videos. Killer, as always, keep them coming.
@@juanestevez8047 thanks a ton! That’s means a lot!
This is extremely informative, thanks for sharing.
Yet another brilliant & enjoyable video from you. Talk about determination & attention to detail.
Reference your slew motor spline shaft, Doesn't Adam from the Abom79 channel have the ability to remanufacture and cut splines? It might be a long shot, and try messaging him. He may help you out and offer a channel collaboration.
Nice to hear about Riley plant to the rescue again.. Proud to be British
Keep up the great work, and I hope you've not got any more hidden challenges or damage.
I love all of the wildlife sounds you get there at night time. Don't get that here in the UK
thanks! I’ve tried contacting abom through a comment but he never responded, I don’t know his email
@@TheHomePros6221 Look under the about section of his channel...it's listed there under channel details.
I used a cast iron welding rod for my starter motor gear which has lasted 3 years so far but the guy at my local machine shop said he would use either the cast rods or a hard facing rods either way use a Arc welder its gets far better penetration in his & my opinion. Heat up your work piece to dull red with a torch in a vice & then weld it start away, grind it using a dremel with the small abrasive gringing wheel & once your happy with your finished gear reheat it back up to cherry rYou may want to think about adding 2 steering cables, 2 pulling, 2 pushing. Your just totally reliant on the steering to work especially at speed as you've not got a rudder. If 1 cable breaks, locks up or comes loose your kinda boned where as if you have one cable on each side of the jet direction nozzle then your covered in the case of failure. . Either way, Great work as usual.ed & dunk in used engine oil or water I can't remember which but there are some really good detailed videos on youtube showing how best to soften & harden your work pieces at home with limited tools & equipment, if the large swing gear isn't included with the bearing then do the same thing but turn it upside down as then it would still be running on the original teeth as half of the gear was still intact good luck, although I think you'll find it easier than you thought. .
Always a pleasure watching you getting things fixed great work
Maybe you could reach out to ICWeld channel re repairing the splined shaft. That guy is just next level talented.🤷♂
Or Kurtis (Curtis?) from CEE
I was thinking maybe Keith Fenner. He has a small oven for annealing and heat treating in his shop and has made splined shafts previously on his channel.
Definitely Curtis , he’s a wizard
was waiting for your part 2!
Ofc for us watchers that took way to long (grin)
Thanks for the upload
@@pahtriac thank you! I’m hoping to speed up getting new vids out once I build a better shop
@@TheHomePros6221
just like dieselcreek u could buy 2 40 foot containers space them 30 foot apart and build a roof on top
those roofs are sometime for sale on marketplace etc
Been checking for ep 2 of this for a while....yaaayyyy
Mr. Darrell! You are a natural teacher, love your content and the fact your channel is growing. Loved hearing some of the Southern Orchestra in the background on some of the video. You do fantastic work, love to watch a fellow southerner! Great Work sir!
Nice work man , the cutters for your mag drill will last 10x longer if you use lube when you run it . The annular cutters can get very pricey . I use white lithium grease in a can . It’s sticky enough to stay put , doesn’t smoke a ton when it gets hot and keeps it well lubricated .
I love watching a master at work! Take care!
Thanks 👍
Dont get discouraged, at least it will be fixed right..I love that dog!
As a mechanic you’re fearless! Great video!
I've been in the gear business for 37 years and you don't even want to think about fixing that pinion. It is junk. There are many shops that specialize in one-off gears but be prepared to pay some bucks for it. I get the impression you're down south so I'd suggest you try B & R Gear in Sharon TN. Good luck!
thank you for the info!
Loved the video!! Watch the whole thing and couldn’t stop!!! Can’t wait till the next one! Amazing comittment!
thank you very much!!
Hi there, what a project. Here is what I would do to fix the gear shaft. First, find out what pitch the gear is, then purchase a spur gear to match the ring gear, hopefully you can get the spur gear with hardened teeth and wide enough to meet the ring gear width. An option would be to have one machined. Machine the worn gear shaft down to a reduced diameter. Bore the new spur gear for shrink fit onto the machined down gear shaft. Cool the shaft, heat the gears and press on the new spur gears. Use a roll pin on the end to keep the new spur gear/machine shaft from slipping. A tack weld on the end might been needed if you are concerned about the shrink fit. Good Luck
@@harryworkshop4001 that’s a good idea I don’t think there is enough meat on the shaft though
Was just thinking today on how your rebuild was progressing..and BOOM, you post one!! I admire your approach to fixing this machine (and all the others you've done too) in that you do it right and fix years and years of wrongs and previous bad repairs and little or no maintenance. There are some very talented machinists here on YT that I would think might take on your gear issue but easy for me to say. Look forward to more on this rig!
Excellent job mate. Well done....there is light at the end of the tunnel!
@@599miata thank you!
Brilliant camera position and detail 🇬🇧🇮🇪
You take on some really interesting projects, I don't think i would have the stomach to rebuild that excervator
thank you very much!🙂
Nice work. I can appreciate what you do since I used to do the same stuff. I switched over to industrial mechanical repair to be inside .

@@carloskawasaki656 thank you!!
I like your videos. This one is nice to watch for someone who has to repair their equipment even if it isn't a total rebuild, they can see what it would take to fix one of the cylinders that go bad.
For me as a hobbyist wood worker and a tool & die maker, by watching your videos it motivates me to get into my garage and work on things in there.
Brother, you have got a lot of patience. Nice work.
Farmcraft, Wes, Marty T, cutting edge and now this ❤
@@johan5453 😌❤️
👍👍👌👌 Nice work! Thanks for the video.
Think you could maybe get in touch with a youtube machinist that would make a collab video of re-making that little pinion shaft? Re-welding it would involve doing a lot of the machining anyhow (the gear cutting being the most involved), in addition to the tempering re-hardening process. Might as well start with a fresh piece of stock.
Thank you for taking the time to make this video. You are doing a great job.
Still amazed by your skills and attention to detail, keep up the great content. 👍👏👏🚜👏👏👍
I have just discovered your channel, I really admire how you work through such a big project. If I rebuild a motorcycle I think it’s a big job, what you do is another level. I am looking forward to the next video. I am pleased the guy in the UK sorted you out with spares. Regards Mike UK
I really look forward to watching your videos you are so knowledgeable and a great mechanic!!
you are very good at explaining things! thanks!!
your very welcome!
What an awesome video again👍
I can't wait for the next part!🙂
The man that can get it done
@@douglascorley6630 lol thanks!
Another great video series. Good job. I also like seeing you clean as you work. Very interesting seeing this thing tore down this far. Looking forward to the next video. Instant hit the like button and watch to the very end.
thank you darrin!!
Darrell. You tha man!! I’m glad you made a video of all this. I couldn’t put all that back together even with video help
Been looking forward to this, great video! Again, impressed with how thorough you are. Sorry you ended up with spline and gear and bearing issues.
keep it up. can't wait to see it come to fruition and you using it.
For the Spline shaft maybe ask an youtube machinist? Keith Rucker or Adam Booth comes in my mind. Keith often did splines and gears but not sure about heat treatment.
Always enjoy your videos and your mindset to do what it takes to get the job done! That splined shaft is going to be a real challenge. Looking forward to part 3!
thanks for sharing your vids.. Nice work 🙂
thanks , very intresting , do more videos please .
Always great videos seriously impressive builds
(Just starting the video) I've been waiting for part 2!😊
first video of yours i watched, was the first part of this series... great content, eager to see more. subbed.
always fun watching you work !
thank you!
Man what a shamozle! Thanks for documenting this for us though, it helps give me confidence if I ever need to go that deep into my mini excavator
Amazing job!!
I hope your financial dilemma will work out with the video. Freaking great job so far!
Always a pleasure watching... Uk
Simply Awesome Work man.
Good job Darrel, you really got a interesting project there
I love you meticulous you are, I think I would of given up at the point you are at with this thing, I can't wait to see this machine up and running again
Man. Been looking forward to this. You are one of my new favorite channels brotha!! Right up there with Pacific Northwest hillbilly !!
thank you very much! that means a lot!
You can do anything, don't let nothing stop you, Dual Shield Welding Wire, is very strong and durable, used by allot of Welders.
For the spline shaft, I normaly heat to about 300C then weld it up with D2 Tool Steel on TIG-rod, then harden to D2 specs and hen tempering. lot of work. Grinding can be easy in a universal toolgrinder. D2 Tool steel TIG-rod is available, just google.
I admire your dedication!
thank you!
U are so talented, amazing job ur doing 👌
L🖤ve the content 👍
Looking forward on part 3 😎
Grtz from belgium ✌️
Great job, great content, and great editing!
So terrifically satisfying watching you bring this mini bulldozer back to life. The Germans say 'clean makes you really happy' and I can see it makes you happy too... But one question- how on earth do you know all this stuff? Is it from poring over workshop manuals late at night or have you fixed all these things before? So amazing! Can't wait for part 3.
love it well done more please
Excellent vid.
Very much enjoy your videos. Keep it up.
Wow, my friend. Your videos are great and you are a hard worker.
It’s such a small and simple shaft there is definitely someone somewhere that can easily make one for you. Plenty of places advertise online custom cut gears.
Great video, thanks for sharing. What a huge amount of work, hats off to you for taking this on. Have you looked for a new pump, rather than just that shaft, might be available - but likely not cheap... Looking forward to Part 3!
Love it keep ahead
Nice video.
I love this kind of video which includes detailed information and explanation even if I'm not an excavator guy.

@@johnclark5502 lol I’ve been wanting one for a very long time
Good to see you again. I realized I hadn't seen anything from you in a while. I didn't notice at first because you don't put out a video as frequently as most of the channels I watch. I decided to go to your channel and see what was happening and was surprised you were not in my list of subscribed channels. When I did get there it showed I was not subscribed? Then when I watched the first video I had missed on The Honda ATV I saw your note on being hacked so that explains the mystery. Anyway, glad to catch up on the ones I missed and have you back bringing the dead to life. Love your videos. This one is the biggest nightmare since that Goldwing monstrosity that you resurrected. Amazing skills.
That gear defenatly can be repaired.
Hack i would have done it myself by just weld the teeth back up while the material is hot. Grind the teeth back to size and go for it If it works it works. for this old machine. It is not like you are going to use the excavator every day. , and the parts are already gone so nothing to lose.
The slew bearing can be repaired by machining the groove out to a bigger size ball and putting oversize balls in it. Usually there is some hardening left inside the groove and will work for a at least a few 1000 hrs
It is also normal for a used slew bearing to have a few mm of play. I think the max limit is somewhere around 2 or 3 mm up down movement.
Sometimes putting oversize balls in it can take up a lot of play, but since the groove has not an even wear on all sides, it can not be done in every case. New seal cord on both sides , and may be good enough for the last bit of the machines life, for a lott less money, if you to the work by yourself for the most part.
Good work
