Fixing a worn out Kubota B7100 Part 1- Splitting the tractor and stripping the gearbox.

I bought this Kubota 4wd diesel tractor a few months ago as a non runner, last time the owner tried to start it, the engine locked up. Turns out he had left it out in the rain without a cover over the exhaust, water entered the engine and it hydro-locked when he turned it over. In the previous video I got the engine running and discovered a horrible noise in the gearbox, lets strip it down and see what's going on.

Anyone can strip down a machine like that...... but few can put it back together! Full respect to you, sir!

[@dznutz3598]

We have not seen him put it back together, yet?

[@eyeballairvent1248]

Marty will do it. He is the master. 😎@@dznutz3598

My dad was a career mechanic and my mum worked nights as a nurse... when I was a little kid I spent many a Sat morning in the garage with Dad watching him working on all sorts of things... this video gave me such a nostalgic feeling of my childhood! Cheers Marty for inadvertantly bringing back fond childhood memories for me... just by watching you strip down that gearbox :)

The good thing about filming it for yputube is he can watch the video for clues of how to put the thing back together😂

I'd have to take a photo every time I took something apart, because you can be 100% sure there would always be something left over after it's been put back together. 😂

[@AdamDeal-KF0PRI]

back in the day we layed the parts out in order we pulled them out and it helps to have a good parts ordering diagram too!

[@stevenr8606]

​​@everestyeti 💡yep❗️ NOW, where does this go❓️ Don't tell me 1st or 2nd piece 😮

[@ronaldheit196]

​@@everestyeti. We used to do that on rotor transmissions and GE T58 turboshaft changes on Coast Guard Sikorski HH52a Seaguard amphibious helos. Lots of Polaroid pics every time because of occasional modifications ARSC would do on us and not always send manual addendum about them sent along with the rebuilt assemblies. Only way to be certain everything went back correctly was lots of pictures. Q&A loved them before and after the swaps. Made post swap inspections easier for them.

[@MrPhotodoc]

Nice to hear the Cicadas outside the garage there. Expecting a very active season here in North America this summer.

[@josephgotter1115]

When I was a youngster, my dad always told me that the manual transmission is the only thing out there that you can put 5 gallons of parts into a one gallon container. Now that I am older and have rebuilt several engines and transmissions, i believe every word!

I have the exact same model so this serie will be a keeper for me. thanks Marty for the great content

You're right Marty-this ole girl has had a rough life, but being owned/worked on by you is just what she needs. Looking forward to part 2. Well done as always, and as many 👍👍👍 as I can give ya. God bless.

[@b7100ripper]

Kubota B7100..... probably the best little tractor Kubota ever made! , well worth the time and effort to get it back up to 100%, great videos , keep them coming , good luck with the re-build.

[@RetiredPilot]

Looking at the way it came apart I would say this machine was looked after with proper oil changes and had a bit of bad luck with the geer box, I owned a 7100 for years and used it a lot on a orchard, the biggest issue was it was prone to over heating and cracking the cylinder head. Take good care of this one Marty and it will last a long time also a great learner for the kids.

[@goodfes]

I sat here thinking my word, I would be lost pulling that all apart. Can see you thinking how can I get some assist with the reassemble, saving ball bearings and clearly making notes to camera (aren't they now a godsend). However I would not have the balls to rip such a complex item apart, but then I thought I am happy to pull PC's & other IT tech apart, upgrade bits and put them back together, that is my trade. I guess each to their own. Quite fascinating to watch your content, really enjoyable !

[@NigelMarston]

I am definitely one for stripping down some complex machinery but I have to put it together very promptly or I lose my way a bit and forget where all the parts go. 😅 Good fun video for a Friday morning. Regards from England. 🇬🇧

[@frukc]

that's why you should film the dismantling process :)

[@DanKoning777]

Nigel, in the video you could hear him saying "...this side is proud-the numbers go towards the face" etc-those were reassembly reminders. I'm sure there were more we didn't hear to aid him later.

I had to do the same job to my B6000 years ogo. It wasn't that bad of a job; just a lot of work. I feel your pain! The damage was caused by me from trying to move a heavy load while in reverse gear. Kubotas are really a top notch tractor.

[@bruceleealmighty]

Love the straight forward builds and rebuilds you do. Primarily without power tools to boot. Thanks for the video.

[@AndrewHCann]

Excellent video Marty T :) also agree 100 on parts need to fix up Kubota tractor and be running smoothly afterwards assembled back together and first test drive too!

[@stevejohnson345]

Brings back memories from when I completely restored my 1979 B7100 4X4. What started as a simple engine repair quickly turned into a D950 swap and complete teardown and restoration project. Can't believe it's been 10 years already and I still have it to this day.

Gearboxes ARRGH!!!.Fortunately i had a Gearbox Guru's repair centre About 5 miles up the road. Never hesitated to send the faulty ones to him.😊 Your skill set is to die for. Thanks for the vid. Part two will be interesting. I'm a wee bit surprised you can still get bits for that tractor.

[@JohnSmith-pl2bk]

There were many sold and still used in other parts of the world... so obviously someone had what was needed sitting in a parts store on a shelf ???

[@daddyg5654]

Thanks Marty showing me the smaller scale repair that I will be experiencing on a White 1365. The same two gears are stripped apart but everything is much bigger and heavier. We're taking apart another White 1365 to get the parts we need. So I'm doing it twice....They're not my tractors. I'm helping a 75 year old miller. Should be fun....

[@MartyT]

Good luck.. yes thankfully the Kubota is nice and light to work on

[@2tana22]

A bit more complex of a job, this day and age we have videos and pics to help the process going back together, fun to watch the process, those 6302 are quite common, thanks for the share Marty

[@lyndonwortley6329]

Off the top of my head I think they are used in chainsaws/strimmers etc along with 6202 that Marty mentioned as well. Hopefully they will be on the shelf of Marty's local bearing factor.

Not surprised. I had to do the same job to a b7100 14 years ago. That model seems notorious for trans wear.

[@Avboden]

Hey nice timing, i've got one of these sitting in my barn right now. I need to pop the front case off and fix the cam oil plug issue that causes low oil pressure at idle. They're really cool lil tractors! Mine came with big spacers on the rear wheels, makes it way more stable. They absolutely need weights on the front for any rear implements though. I took my front loader off and tried to pick up a tiller and it did a wheelie!

[@amossnowdaharleyman9179]

Fun to watch. Here in the U.S. if we tear into a transmission that deep we just replace all bearing and seals. Lot of work to get into it and all of the original bearings have same time and abuse on them. Some have already failed but we wouldn't trust the others to not fail soon.

[@Treeplanter73]

[@aserta]

When there's been this much chewage inside a gearbox, it's always a good idea to just replace the bearings. Not worth dealing with a potential frag inside if you've gone as far as taking it apart, especially on a gearbox. The loads will amplify any small defect and cause havoc. I did this mistake once and i had to take the whole thing apart from scratch. Just not worth it, probably one of the most miserably jobs you have to do, to redo something. :))
