Well, for anyone wondering why the labour bill is so much higher than the parts bill there's your explanation right there. Knowledge is hard earned and worth every penny.

55 minutes of pure excellence in knowledge and attention to detail! Loved every minute. Thank you for filming this!

Been doing repairs on cars for over 4 decades and never did the finer details like using the lead balls to get shim measurements, even though I should have a few times. I got the utmost respect for your attention to details and measurements. You all are a credit to the craft and have me revisiting how I do work from now on.

Customers who bring their tractors to you surly get some of the most excellent quality work i have ever seen. Amazing checks on all the specs such attention to detail. GO ZK GO!!!!

I'm not a mechanic and I've never farmed a day in my life but this was amazing vid. Great to see the detailed repair process. Thanks for the upload!

You can tell this guy is a veteran mechanic by the wide variety of hammers he has.

I am definitely no mechanic but I am firm believer in housekeeping. The way your shop looks will definitely reflect on your work. The shop is by far the cleanest I have seen.

Been a auto mechanic for 12 years and I've never seen a repair like this before, so awesome to see! Keep up the awesome work and great videos!! Much love! 😄

When people think that mechanics just "slap" a set of new bearings in a machine , I'll gladly refer them to this video . Keep up the good work !

Great Job Zeth. Thank you for taking the time to walk us through step by step. Keep it up.

Back in the day, I use to work at my father's shop. He was a Ford agricultural tractors mechanic, later on change to new holland, watching you guys, bring me great memories.

Wow! We had this done on our 9630. You did an amazing job. Well done, I wish you were close by, this is what a farmer loves to see in a master tech. I never thought it was this involved and so many special tools needed.

Customer made a good decision of doing both at the same time. Another exceptional video, great detail step by step explanation on procedures of replacement of bearings torque specifications. Keep the action coming. Definitely catchya at the next one. Stay safe!!

Without guys like you, the farming industry would be dead in it's tracks.

I grew up on a farm in Louisiana. We worked with and maintained mostly Massy Fergs (Cat engines). I remember being awed by how good my Papa was with this stuff. Now I'm looking at an entire new generation of badasses. You guys made my day!

These men have an amazing set of skills and knowledge, and, not a line of Software code needed ! It was a joy to observe you diagnose and repair this item.

Zeth: What a marvelous video ! Your speech is about the right speed to convey technical info, no "UMMMS" or "AHHS" & you maintain an even audio level all the time. Your explanations, & your technique for executing this repair are second to none. I am not a mechanic, but I live in southern Alberta farming country & troubleshoot electrical & electronic problems for the locals. At 81 years of age, even if I was inclined to to jobs like you do, couldn't. I am always interested in watching folks who are experts with heavy equipment fixing the problem at hand, & I ALWAYS learn something. Thank you for an excellent & informative video.

This guy is a real pro! Not only excellent at what he does mechanical wise, but awesome at explaining it all to me/us. Subscribed.

Gentlemen, You are true professional and I love watching your repairs. Fantastic!

You guys done a great job, and also very good thinking on the farmer for not ignoring the oil leak by just replacing the outer seal. A bad bearing like that if left any longer can do a lot of damage to the rest of the parts in the axle.

Shows the importance of dealer support and techs who do quality work. Thanks.

You know Zeth, I watched this episode a second time and I have to say. A special thanks goes to your dealership also, allowing you to take the time to film and explain in detail your days task. Take care Bud and have a blessed Thanksgiving.

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.

You have to be the most intelligent and skilled technician I have ever come across, your knowledge is second to none. I have watched a few of your videos now and to say you impress me is an understatement. I hope you are very well rewarded and wish you well in the future.

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!

Not sure how I came accesses this, but wow! Very interesting the amount of calibration that goes into a couple bearings… Great video and explanation as well, very detailed🤙🏽

This looks like such a difficult task. I’m sure it must feel amazing once you complete the job. Great videos!

Outstanding video, I was a field millwright for over 45 yrs. People sometimes don’t understand all the experience and knowledge working people use to do there daily job. Thanks.

Your a Legend 🍺🍺👍👍💚 At the top of your game. I'm retired at 70, worked 47 years as master technician at German car dealerships. Work safe, avoid injury👍👍💚

Great instructional video. One can't truly appreciate the care involved here until you think of the weight and size of the pieces he's working with and the precision that is required to achieve the required preload. The old manuals suggested using a torque multiplier to get the necessary torque values.

This is the first video of yours I have watched. As a master Ford Lincoln, and mercury technician I like when I saw. This video shows the reality that not all repairs are straightforward. Ingenuity and compromise are also OK. I look forward to watching the next video. Good job with the presentation.

I've been around auto shops, this gentleman's skills are on a whole nother level!

Good video, helps us understand what goes into these jobs and why it just doesn’t take a couple of hours to do them properly.

I am genuinely impressed with your skills. Learned a few things too!!!

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). Best repair video I've seen on a big Green machine, well done!

young man you are an excellent mechanic.having worded 35 years in manufacturing im impressed by your quality of work .bravo

Really enjoyed your repair video. Learned quite a bit about tractor bearing replacement. Never knew the fit is so precision that they need a thermal application to expand enough to fit the axle. Awesome job!

This is what you call a real technician he diagnoses the problem doesn’t cut no corners doesn’t throw parts at it uses a torque wrench on every bolt

Great videos, I’m telling all my fellow farmers about your channel. Some of the most informative I’ve ever seen. Keep up the good work, and thanks.

Farming nowadays is not just chasing cows. What a wonderful job, - well done!

That sure is some massive equipment to work on ! Great watch. Enjoyed that. Thanks for uploading

Zeth is a cool guy with a lovely temperament for this type of work ... never appears to get flustered . All hotheads out there take note !

I know nothing when it comes to this type of machinery but I watched every minute of it...great stuff!

thanks for the video I learn a lot from your work techniques I'm studying to become an agricultural mechanic and watching you work helps me build my confidence.

Viewed 11-22-21 from Fairview, Illinois Hi Zeth I worked for Massey Ferguson Inc field engineering for 32 years. Regardless the color of the paint, you must be on top of your profession having received the BEST FACTORY training necessary to perform the quality of work you presented. With the cost of this tractor, a grease monkey has no place working in your shop. QUALITY WORKMANSHIP RULES. I subscribed to your channel. I am retired reminds me the days when I was working, keep up the good work and attend all training when come available :-)))

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.

This single video showcased some of the best tried and true tips & tricks I’ve ever seen on RU-vid! 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 . . . 👍🍺🍺🍺🍺🍺

You guys ROCK. You guys are professionals. Just an amazing experience. Thanks.

Great job Zeth, your complete explanation and attention to detail is exactly why you are a Master tech. Keep the great content coming. You definitely deserve every penny you make.

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 😁

I love your logic in how you approach problems, you don't just keep hammering when clearly it needs another approach.

Hey man. I’m 100% sure you made it better than in the original condition. Thank you very much for sharing. Excellence in action.

Waw ! what a master technician, it"s amazing how delicate he handles the intricate internals of such a vast machine and overcomes problems that would have me taking a pack of TNT to the whole lot 😂 I wouldn't mind betting that he repairs watches in his spare time. Thanks for inviting me into your world of heavy mechanics I loved every minute of it, Greeting from across the pond

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 ? Complete Master. Green Iron Pro might just do it. Thanks for the videos, a Master Class.

These two guys are excellent mechanics. They are very knowledgeable, patient and work well together. It's refreshing to see that they are very professional as indicated by there use of high quality, professional tools.

Amazing work, you are great is an understatement. That farmer is lucky to have you work on his tractor.

Opět precizní provedení servisního zásahu. Moc šikovný človíček. God bless.

That was absolutely fascinating. No need to watch anything out of Hollywood when there is quality videos like this to watch.

I am just a dumb finance guy. I love watching this stuff and I appreciate your skills.

Phenomenal Job on some big a** gear. Well done! Most appreciated how well you documented and shared this heavy repair.

Wow! Talk about a heavy job!!! That drive train is incredibly complicated! Definitely a job for a professional. Thank you for all the extra work showing what you do and special thanks to your employer for allowing you to take the extra time!!! Definitely not my grandfather's Farmall Super H!

Most people don't realize just what mechanics do, let alone what tools are required. A Doctor works on 2 models, we work on many and are expected to be experts on them. This is a great vid, and shows all facets....the expertise, the mistakes and the non-shade tree mechanic tools required. If we do our job right, usually you won't be able to tell from an external observation. But that's us...like heart surgeons, but without leaving a scar. Another great vid from ZK!

Really amazing to watch you guys work on that axle. Thank you for the video.

Wow! Fantastic!! Thanks for all the experience you have shown your audience.

Very cool, brought back memories of working on large logging equipment and large industrial engines up to 15K bhp (15" Bore, 21" Stroke, 20Cyl) Diesel engines. Thanks very much for sharing. I truly appreciated your attention to details.

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

Not something I could do in my shop. This was really something to see. Thank You for showing this.

Calm, cool, professional, and patient. Impressive work.

Wow! Had no idea how much work, time and people went into something like this. Thanks.

Isso é impressionante ... Parabéns pelo profissionalismo e maquinário assim como as ferramentas!!!!

BIG shout out to these guys and farmers everywhere ! They keep the equipment working, for the farmers who feed us all ! Thank you! Super smart customer, if the axle is already out...YUP replace all the bearings and seals!

I just found this channel - suggested by someone - and its interesting to see how you work on these large machines. Not what I was expecting - not that I had a set point made up - but I look forward to seeing more of these.

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.

Back in the late 70s I worked for my Dad at a John Deere implement shop as a mechanic. We used the same techniques back then welding a bead in the racer, heating the bearings using a rice cooker , and we used lead ball to it find how much shims were needed. It seem lot we did a lot of bearing jobs when farmers were water leveling the rice fields.

Fascinating. I'm a woodworker, so this is all new to me. But very interesting how it all works. Thanks for the content!

That Was Amazing To Watch You Guys doing the Front Axle Bearings, I Used For John Deere 12 Years I Did in England. But I Had Cancer and That Was The End of Agricultural Service Technician Career, I Really Hope To Get Back To It Sometime.

Epic work guys. That interference fitting can be a pain even with smaller stuff but the frustration definitely scales up! Well done.

I liked that professional job you did there . the special tools you have are essential with that weight . that was a very tight fit for the bearings and seal ring , hard to do without damaging new parts , the key is not trying to rush the job .

That was absolutely fantastic! I really enjoyed it. Thanks so much young man.

Nothing beats go old American ingenuity. Outstanding you guys.

You could get a bearing induction heater, maybe in works like this you could save time, make less mess than use hot oil and being more accurete with temperature. Also, you could measure the spacer and the shaft so you could calculate the temperature you need expand enough to create a clearance fit. instead, for bearings is better to not exceed 230°F. Very good video, you are a Mastertech!

first time viewer, new sub. really cool video. love all the mechanical. the guy helping you looks like he's doing a great job. i was a long time auto tech. one of the ways i have seen to shrink surfaces mostly for install is unregulated co2, it gets really cold really fast. a close quarter containment was used (cardboard box). seemed really powerful and useful in the right situation. recently i have been exposed to a product call RINHO DIRT. oily messes can be cleaned up with a broom and dustpan and then thrown in the trash without worry (non-leaching). and the floor is not left oily residue.

You're helper is something special, let me tell you. The look on his face trying to figure out which way to put the crow bar was a hoot.

Don't know how I ended up here, but I surely am glad I did....stayed to the end, didn't seem long at all. Really interesting and a good learning experience on how master mechanics work. This is how the USA became great, and stayed that way until.....you all know what happened. Nice to know the USA still has great, experienced, and skillful folks doing what they do best. Hope a lot of people can take away, the yes we can mindset from this video. Really well done :) PS From SoCal - You guys give hope that this country can become great once again.....

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.

26:00 That was the right tool to fix that ring and also add two handles two side of the cylindrical hammer to ease your hammering force. keep up the good work. And for cooling the ring liquid nitrogen is the best cooling agent for shrinking the inner ring. thank you for video and detail info

Well done on the front axle repair,you know all the tricks,and all done with basic items.

Great job! Love your shop and your specialized fixtures and tools.

That was very enjoyable to watch. One must be so careful on such a heavy piece. Amazing the precision. Great Job!

Just came around randomly and have to say, i really enjoy your content! Nice produced, high quality and seems like professionel working! please continue like this, ill sub 👌🏾

Informative and engaging! While the only farming I will ever do is in a video game, I still love to watch work being so excellently done on these big tractors. Remember kids, if your fluids look like glitter, it's probably buggered.

Pokazaliście bardzo fachową pracę i profesjonalizm dziękuję za film i pozdrawiam was z Polski :)

First time watching your channel, but had me hooked from the beginning, really enjoyed watching.

You guys are real pros, with some smart tool fabrication in the mix.

Yup, the volume equalization on this video is perfect. Amazing how just one bearing can cause so much carnage... wow.

If I recall the lead ball technique came in somewhere around the 50 series. The old 4020 and 4430 would just be a torque to about 75 ft/lb and lock plate. 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)

I enjoyed this video well done, you’re not just a mechanic but an Engineer too. .

Outstanding content. Reminds me of similar issues with the old 4900 Massey Ferguson, used to check with the DTI regularly for excessive axle play.

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.
