It's like the repair of a motorized heater flap in my old Lincoln Town Car, The Money Sewer. $30 part, but $700 to completely remove and replace the dash assembly to get to it. After a long and bloody fight, FORD warranted it. My wife loved that car, wouldn't let me get rid of it. She got mad when I danced after a truck hit the front tire/fender and it was totaled. I couldn't fault the mechanic's prices. It took a lot of time to futz with the dash, but only about 5 mins to replace the part.

[@MarinMircea]

It's not really the bill's fault, but take into account that many dealers or repair shops sometimes if not often, have poorly trained personnel which most of the time trains on your machinery while you pay repair hours, not to mention in the field or in farm experiences with the dealer, when you pay for the hourly x2 because they send 2 individuals, plus their transport, and it takes a full day to diagnose, and after some few hundred bucks, it was a cable, or a fuse... At least that's what happens in Eastern Europe.

[@DrBlood-cq2cm]

The money isnt for knowledge or labor, its for the heavy machinery to use brute force for disassembly/reassembly. Other than that, a pretty routine diagnosis.

[@Brian-ug7du]

I just found this channel, and I’m very happy I did. Great job showing what goes into doing the job the right way. One thing about welding bearing races to shrink them out. I do it often but once I had a very heavy duty race that I had just pounded out. I set it on the bench and a few minutes later it exploded! Now I wear a face shield and am careful when doing that so I don’t get shrapnel imbedded in my body. The hardened races don’t like the weld stress too much. I hope this helps some people avoid injury. Also with that collar and inner race you had to fight with that big puller and heat. I would just take a cutoff wheel and cut 1 groove into it at 12:00 and get pretty close to the shaft but don’t hit the shaft. Then just give it one good hit with a hammer and chisel in the slot and it will crack it open and you can just tap it off the shaft. No puller or torch needed. Keep up the great work!

[@Tom89194]

The groove trick is real nice for the bigger bearings, saves a LOT of acetylene and O2. It can get tricky to split open the smaller ones without cutting deep enough to get the shaft sometimes.

Outstanding in every respect; professionalism, workmanship, skill level at the highest possible and attention to detail. One point on torqueing, we were taught in the USAF that you should only click the torque wrench one time, each additional click actually changes the torque value (I realize at 670 ft lbs a few more lbs probably makes no difference but in another case maybe would be crucial).

Zeth, Master Tech, perhaps not a good enough description of your skills. Just watched the video showing the work on the front axle. No software, no electronics, no laptop. Heavy lifting, special tools, working to tight manufacturing tolerance. Understanding heat and cold treatment of steels. Having to be careful with hot oil, hot bearings, being aware of the guy helping you. Carefully replacing bearings and rebuilding the housing to Deere's specifications. Welding, another skill needed. No wonder the customer would want to do the other side as well. If he watches the video he will see he made the right call. Yes it is more service work for the dealership, but also knowing that the tractor is repaired properly, will be good to go for the customer for a very long time. The previous video was the 8RX, all laptop, code, cables, adapters, software, old software, updates and improvements. From a blacksmith to a magician. So, Grand Master ? Great Master ? Deere Master ?

I really enjoyed the video. You know what you do and it shows in your work. I worked for a John Deere dealership in germany 20 years ago. The biggest tractors we serviced where 8000s. There was a rumor back then that two 9000 series tractors exist in germany. Removing and installing bearing races is such a satisfiying work to me! Also this work, while heavy is also delicate. One tipping over shaft and the toes are alot flatter. Also from my understanding your are well equipped. So that you can focus on the work and not have to fight the lack of equipment much. I would appreciate the huge workshop you have there, because it gives all the space needed to do such work. But you always get the noice, smoke, dirt and dust from the other guys also, I asume. And also I like all the self built gear that you have around. It was the same where I worked. We borrowed special tools from Deere and the old timers copied it, so that we would save like 13,000 €. And we had like self built wrench extensions around which where forged by the old timers, back then when there was still time for that. And thoose wrench extensions where so tough and well made, they never failed. Regardless of how much load you put on them.

After the lead ball procedure, we did all with the shim pack just the way you did this one. Nice work. Tip- our grocery store has dry ice, I have used it to aid in thermo shrink when needed. (4850 pto fix…..book says double split…..with dry ice on the back race removal, you can eliminate the 2nd split)

The lead ball technique came into play because the 30 series had all kinds of trouble with axle bearings. Also the brass "thrust" washer is a joke.

In a JD dealership in late 80’s. The 5020, 8630 were just torqued to 10? foot pounds, then the triangle lock plate was installed. On the 5020 I did, the bolt was loose & backed out enough that the lock plate was between the heavy washer & the bolt. I unscrewed the bolt by hand. Being in north east Montana in the winter, we put the axle in unheated storage, Technical Assistance told us to heat the oil to 400°f, we had to tear apart shotgun shells to get our lead balls, because JD did not have a part number for them yet. Part of the directions that we got from JD technical assistance were hand written. After every step we had to call technical assistance to see what to do next. They would tell us, then send a fax repeating the directions. By the time that I did the 8630, we had a 3 ring binder service manual along with the paperwork from the 5020. When we ordered the shim kit for the 8630, it included 8 lead balls. We had to rotate 20 revolutions in each direction after each torque stage. We use someone’s 10 foot satellite dish base to hold the axle on the 8630. On the 5020 we mounted the tire on the axle as a stand. The procedure is basically the same way today. We had to tighten the bolt till we had about 50 to 75 foot pounds rotating torque, that was to get the bearings seated or your zero end play. We only used the dial indicator to verify that our end play was in the new JD specs. Hello from north east Montana. 10 miles from the Canadian border.

Yes you have a tool to help you get that inner bearing in there. I ALWAYS keep the inner race pieces of roller bearings like that. Have a milk crate full of them. Alittle work with a die grinder or drum sander wheel on the inside will make it a slip fit on the shaft. Once you have that if you need you can shorten up the outside if you need to to clear the bearing cage. Now you have something that you can give the beans to with a hammer and not damage the good bearing.

[@ZKMasterTech]

Did it look like I had a problem getting the bearing on the shaft? Trust me if the temps werent right on the shaft and the bearing even making that race driver is not going to save you. You're just going to get it stuck harder. If that bearing don't slide easily it's not going to go. The spacer is a different story. It fits way tighter.

This single video showcased some of the best tried and true tips & tricks I’ve ever seen on KZbin! If that wasn’t enough there were some new ones I never considered to use. Appreciate you taking the time to share these solutions to the community! Rock On . . . 👍🍺🍺🍺🍺🍺

Thanks!

[@gilwolf7556]

I would be extremely lucky if a guy like you would work on my tractor. Thank you for the class

[@jimsvideos7201]

I don't know if that was a big job, but it was definitely a whole bunch of little jobs in a row. I admire your methodical approach, it feels like you did everything you needed to so the job would stay done the first time.

[@darolfitch8917]

Mr. Master Tech I really like watching your videos, I am amazed that this equipment runs at all (so many moving parts) , and in a harsh environment(dirt). It must just be a constant battle to keep this equipment running, with wear and tear. Plus fighting engineering and design issues. It just must cost a small fortune to keep these things running. Thank you, and please keep the videos coming.

Planning on becoming a Diesel tech for my local Deere dealership after high school and college. Watching this just makes me excited for what I will get to do once I’m apart of the trade.

[@pauljw4472]

Great video Zeth. Love watching you guys fix the big boys toys, even when things don’t go to plan!!! Good idea changing rest of bearing as you’re already got it apart 😁

[@tombaker2523]

Big toys big money 😮 hell of a job and video bring some more stuff really enjoyed the presentation of specs and procedures ❤

[@mtwz71]

Y’all did a great job on that repair. Bearings and retainers can be a pain sometimes. Good skill set and thinking on how to get the job done. Keep up the good work.

[@stanwooddave9758]

AWESOME Video, thanks for sharing. Just a thought, reference having to let that washer basically fall on to those lead balls. Go / visit your local welding supply store / maybe Snap-On dealer, look for a Magnet that has a on/off switch. Cost should be depending on size less than $40.00. For one with a pull strength of say 20 pounds or more. This tip is from a welder guy (68 yr's old, still welding.) FYI. Another possible use for the on/off Magnet is to help clean-up some of those metal-shaving's.

One of my local Deere techs told me to check the axle seals every day to see if they are moving out. It’s an early indicator the bearings are going. We’ve lost both front and rear axles now on our 9330. In the beginning of your video the seal has clearly walked out of the housing.

[@shovelguggelheim8454]

Yes, it should be part of a daily inspection, after checking fuel/oil/coolant etc. A walk around to look for oil leaks, loose bolts, broken bits etc. Only takes a couple of minutes and can save thousands.

[@rasmushummeluhr5718]

How many hours did it have when they failed?

[@hordboy]

@@rasmushummeluhr5718 IIRC around 3500 and 3800hrs. Rear, then front.

Never thought i could be so tedious to change tighten a nut (The planetary bolt) - We can understand why it takes so much time... Thank you for sharing this it sheds some light on how it's done

[@harveyrousejr.2069]

Great job Zach. I've owned and operated Deere equipment most of my adult life. Nice to observe a professional master technician at his best. We have the pleasure of working with our local master tech Allen Brown with Quality Equipment.

[@duanedale2505]

Used to do those on 84- 8630 . Torch, welder was man’s best friend for taking bearings off and a hot plate to warm bearing up to put them on back in the 80 ‘s

[@1oddtech]

I bought a induction heater for bearings and it does a great job and no worry about catching anything on fire and it evenly heats the bearing your trying to remove.

[@Rx7man]

I use a toaster oven

[@1oddtech]

@@Rx7man can't wrap a toaster oven around axle shaft tho.

[@Rx7man]

What amazes me is that, in order to be economical, such a tractor must be able to make a farmer not only enough money to pay for the tractor, but to pay for expensive repairs by skilled people and well-equipped workshops like this.

[@Adam_Poirier]

Nice job dude. I like this longer video. Every step you take is methodical and organized. I really like your approach. I said it before you John Deere guys working on this bigger equipment are no joke you make it look easy.

[@ZKMasterTech]

Thank you very much! You've got to be methodical so you don't take one step forward and then ten steps back. Time is money.

[@buffsheeri]

"oh my" and "oh that's not good." are not things you want to hear. BTW great channel and excellent repair, thanks for sharing.

[@offroadrepairman]

I’ve done this job, in the field with my service truck, off my bumper and a few pallets. Crazy, I just read your bio. You went to Wyo tech in Laramie. I grew up in Laramie, but I’m quite a few years older than you. I was working in the mines near Gillette Wyo, for the cat dealer In 2007. I’ve been self-employed since then, mostly contracting to construction companies. Nice work putting these videos together, I wish I would’ve taken the time to do something similar to document my experiences. I tried hiring people and growing my business with the intention of being able to pass along these skills to other people. It about bankrupt me, now I see I could’ve made videos.

[@olejake1932]

I am impressed that there is no gasket to deal with when reassembling the unit. That is impressive machine work facing those pieces
