Fixing a worn out tractor Gearbox and Lift Unit - Kubota B7100

I bought this old Kubota B7100 a few months ago as a non-runner, it has had a hard life and is quite worn out.
In a previous video I got the engine running and discovered a horrible noise in the gearbox, found chewed up gears and bearings.
The new gears and bearings have arrived, lets put it back together and see how it sounds..
Thanks FridayParts for sending the gears fast post, check out their website here - www.fridayparts.com/

Nice work on the video! It’s cool to see the gears we sent out fit perfectly. Thanks for trusting us with your gear⚙

Thanks for the parts! I was having trouble finding them in New Zealand. Cheers

Best channel on YT no stupid intro , no background music and not talking for the 1st 20mins before picking up a spanner

[@stefanliljeholm2351]

agree❤

[@linmal2242]

Just common sense; well maybe not so common these days !

[@aqua-op]

I appreciate how comfortable Marty t is with the silence, I can imagine for other creators they're probably worried about these stretches where they aren't talking, from seeing other creators, from bad youtube advice sites and influencers telling them not to leave dead audio etc. I don't really blame them, but the royalty free new age rock music is only detracting.

[@Spitter-ud8jd]

I want to know what brand of spanner that was. I need that feature in my life!

[@leslieaustin151]

Yup, useful for sure. When my mate dropped a spanner (on me, I was the apprentice, so under the vehicle) he used to say, “wipe the blood off and hand it back, please”… Great video, as always. Les in UK 🇬🇧

Reassembling a gearbox is like the world’s most satisfying Lego set.

Yah,But you get to use a Hammer,LOL. GORD

[@dougstubbs9637]

Rebuilding gearboxes is the singular most unsatisfying job. Nobody believes how long it can take, how many fu…..frustrating times you get sent the wrong parts….somehow worse for gearboxes than any other component….and the shock on owners faces when presented the invoice. Stop complaining dickhead, if you learned to drive a bit better, you wouldn’t be having this conversation with me. The things don’t just break themselves. Some days, I hated being on the spanners.

[@Mike01129]

I know this video condensed a lot of hard, frustrating work but I never heard a hint of frustration or a thought of a curse word. Hats off.

[@martialme84]

Love how you're explaining what you're doing, while you're doing it. "...those grooves are there to let oil to the bearing...". That is actually very helpful. You could easily become a very well respected teacher at a vocational college or a trade school, if you aren't already.

[@chrissscottt]

I'm always impressed by mechanically minded people and their ability to reassemble complicated bits of machinery.

[@pauljoseph8338]

Seeing him disassemble hundreds of tiny parts, with the goal of reassembling those parts, gave ME anxiety…

[@shize9ine]

If you record the disassembly you can watch it in reverse for reassembly! I’d bet $5 Marty has watched playback for that reason before.

[@kaboom4679]

The REAL tricks are locating replacement parts , because anything truly worth fixing is probably long out ofanufacture . The second trick is locating all the parts that DIDN'T need to be replaced , because of the peculiar quantum effects that project machines seem to generate . I always have a part or 20 that manage to fall into transient black holes no matter how well and carefully I label and store everything .

[@philyew3617]

Nice work Marty, good to see a craftsman at work and, a very useful little tractor. That gearbox brought back memories of the first box I was given to overhaul on my own as a young apprentice. I had everything laid out on the bench perfectly, all the correct new parts ready. The foreman (brilliant guy) came over to check everything before I re-assembled it, pat on the back and me feeling quite pleased with myself. Then he picked up a cardboard box and swept everything off the bench into that b@@@@@ box. Then, he gave me the box and said- Now put it back together! It took me about three days. Lesson learned, make little sketches or notes if you have to, and learn to use the workshop manual, (this was the early 60s so no videos). He got called some naughty names but he really was a brilliant mechanic and teacher. Happy memories of when mechanics fixed things without a laptop and USB port😊.

[@MartyT]

😆

[@jafo9346]

The magic spanner retrieval at 14:41 was a nice touch there, Marty. Great job on the rebuild!

[@april7_]

It was not a film trick, those were the hands of Marty as magic as always! 😄

[@valis6761]

Good to know the trick when you drop a small screw or nut in the gearbox 😁

[@svthorasailing4868]

Hi Marty thanks for explaining the shaft,yes that was my comment,you were correct,cheers.

[@NoPlanProjects]

I'm glad you're saving this tractor. I see a lot of them go to scrap or just rot in the back 40. Not old enough to be collectible, not new enough to be desirable. Even though they're small, they're also one of those most challenging Kubota tractors to do gearbox repairs on. Well done.

[@andrewjones-productions]

I have often wondered why Marty is so good at fixing machinery. Thanks to his uncharacteristic editing mistake of including the magic hand retrieving the spanner, we now have evidence that he is not really human, but a superhero mechanic. Knowing this, my feelings of being inferior are somewhat alleviated.

[@glenpaul3606]

I saw the video of you taking apart the transmission and now I am amazed you remember how it all goes back together. A very talented man indeed. You did a marvelous job.

[@HowP88]

The advantage of creating a YT video of the disassembly - play it in reverse for a reassembly guide!

[@glenlongstreet7]

I really enjoy watching you fix mechanical things because it keeps me humble. I haven't a clue what you are doing. I studied electronic and nuclear engineering, and that made me feel really smart, I lived in a submarine which is a really cool classroom. But again, there is no way I could do what you do. Your videos remind me of that. You Tube keeps me humble.

[@BrassLock]

Very few people could tolerate the 24 hour/7 stress of living in a submarine. So you don't have to feel REALLY humble, just a tiny bit will be OK.

I sang one song. It was, in retrospect, disgusting and demeaning. It made 100 hardened sailors blush. It was not about a submarine. Since then, I have become a minister. Every once in a while I remember the lyrics. They still are revolting. What goes into you mind never comes out. Be careful what you do.

Absolute champ of a little tractor. I love it. So small, compact and strong. These have a big following here in the states. Many people restore them. Parts are difficult to come by. Also the pto rotates opposite of most standard implements here in the states. Finding a good reversing unit is near impossible. Well done. Cheers from upstate New York. 🍻🍺🍻

Splendid fix! People underestimate how handy small tractors like that can be.

[@robbob1436]

[@robertgeorgewerner]

Marty, it was a delight to see this video. My family has a b6000 that we have loved for all my life. The tractor had sat for several years after my father died, not being run and finally being very hard to get started. My nephews took it up to their place and are now using it routinely to till their garden and manage the trails. That will be 6000 is deceptively powerful. The only limitation we found to it was that it didn't weigh enough to accomplish some of the things that it acted like it could. Seems like that little tractor, supposedly a 12 horsepower tractor had the heart of a much bigger one. Fun also to see an intermediate step between the 6,000 and the modern Kubota tractors. I'm betting that you will love having that out of your island.

[@harrytaylor6854]

A double yoker , bet your glad you weren't laying that one eh Marty 😂 , great video as always , the transmission coming apart and going back together reminds of my days working for Versatile farm equipment assembling transmissions, axles,Pto's, 3 point hitches and hydraulic cylinders, always a challenge and keeps the memory sharp, the camera is a big help nowadays i take pics or short videos of how they come apart, just to make sure i put them back together correctly, that little Kubota B7100 would be perfect for me to plow the snow here in the winter, a blade is all i would need and its a good thing i make those for a living, I have seen a few of these on the web here in Canada and people want a kings ransom for them even though they are tougher to get parts for them nowadays , i just one the little diesel on them, those things will tick over for half a century with good regular maintenance on them, they were well engineered when they were new, easy to tell by looking at the quality/design of the casting and how easy it was to remove the fenders and pull apart the gearbox. 👍

[@warrenvalentino5763]

Good Morning. i love watching your videos. love your attention to the details. i am always impressed with how you remember how everything goes back together after you take it apart.i am Not good with mechanical stuff. but after watching your videos for years. i am working on my 1995 polaris magnum 425 2x4 atv, i started out just replacing the head gasket ( thank GOD' i did Not have to take the whole motor out). i was putting the cam shaft in when i found out the cam shaft exaust part is worn out. i am working on putting the new cam shaft in and slowly putting the top of the motor back together again.

I'd love to have something that small to do odd jobs around my small acreage.

I used to own a B7100 years ago, it was set up as a backhoe with a bucket in the front and a digger (too large, really) in the back. Fantastic little 4wd machine, keep it serviced and it runs like a swiss watch, hated to sell mine but at the time i had no choice. Love the videos, cheers!

Your talents never seem to end yet as a kid, I would race my old car, and lose some gear in it, and being a kid that did what we did with what we had, built many transmissions similar to this. Granted not as complex as yours but paying attention to detail is really the trick plus a camera comes into play anymore. I am talking the late fifties or about sixty years ago.
