How to fix Kubota 4X4 drive coupling.

Fixing Kubota front drive shaft couplings.

[@csnocke5]

I like this guy. He doesn’t over complicate shit and he uses a big hammer. Thx for the vid man

[@Digginok]

Couldn’t find my small hammer.

[@jweb51958]

good show the tube had me boggled early on... thanks

[@SundryTalesOfConstance79WESTY]

Nooice! 😎 STOC

[@kb7722]

You should put grease on the splines. If not the splines will fret and fail. Or go they get oil to them?

[@Digginok]

Probably wouldn't hurt to grease them, they are dry.

[@davidnull5590]

The coupling there seems to have been made using sintered (powdered) metal and likely not heat treated, I wonder if it was designed to be the failure point in the front drive train? What else is there that would break/fail first? It's probably not worth the time to machine a replacement piece out of solid steel and then heat treat it. Any thoughts?

[@Digginok]

I think it could be like a safety fuse, would not want to make something else break. The couplers are around $25.

[@burningdinosaurs]

Nice fix! I bet that's a pretty common problem! Thanks for the video!

[@Digginok]

Thanks, yeah I think it happens to all of them at some point. Thanks for watching!

[@timebert6141]

I welded the stump jumper back on the shaft of an old mower. It was so worn out and the guy wanted the cheapest thing I could do!

[@Digginok]

Customer is always right!

[@Digginok]

Tim Ebert very true!

[@steveaguinaga3821]

I'm bought old b7100 non-HST about same problem. No idea how to fix. Trying to get money back.. Enjoy your vids

[@SergioGarcia-eg7eg]

Thanks for the video. Helpme to find my problem really quick

[@1myourpap175]

Where the coupling sized on that one where they wouldnt move?

[@wallycleaver1320]

Boy you got big fat fingers with some battle scars hard to get them in tight places i bet.

[@darwinboyful]

Baddd

[@mikegibbons1718]

Frank, Thanks very much. My l2500DT had no 4 wheel drive today when I went to pull some cut up trees. I had no clue why it would quit. My first thought was that it would probably have to go to the dealers and I would be looking at big bucks. I'll ck it out. Again. You give some hope.

[@Digginok]

Glad o could help!

[@jesseemerson9615]

thanks for making this video much appreciated

[@sassafrasvalley1939]

That’s what I used to do when I went to visit the in-laws... fix stuff. I enjoyed the visits and we never crossed swords. That’s a simple fix when you know how it works. Thanks Frank.

[@Digginok]

Definitely helps keep me out of trouble!

[@janiscampbell3039]

can you give me the part # for the replacement spline inside of the drive couplers for the L5470

[@Digginok]

Your dealer has the numbers, sorry I don’t have the books

[@stevenmurata4392]

"Fix it" Frank at it again. No mechanics are gonna make anything with him around, lol. (Only way to stay in business!) Do you farm or raise any animals?

[@Digginok]

LOL, yeah we have some cows and my daughter raises boer goats for show.

[@kennethdodds2323]

I guess nothing lasts forever. For some reason I hadn't thought Kubotas would be something you were real familiar with. Not sure why.

[@Digginok]

Yeah it’s a fairly cheap fix, $50 for both couplers. My father in law bought his first kubota around 2001 I think.

[@michaelcarney4602]

Where did you get the coupling? Cant find it anywhere mine is 16 spline

[@Digginok]

well I went to the Kubota dealership.

[@bryanseidel4564]

how many hours are on your tractor??, im looking at buying one which is a 2012 year build, same model. It has 1800 hours on it and the dealer says the 4wd does not work

[@Digginok]

I think it’s about the same as 16-1700

[@bryanseidel4564]

@@Digginok I went and views the tractor yesterday the drive shaft was missing, the spline output shaft from the transfer case was missing. They are trying to tell me I need to split the case to reinstall the drive shaft to the front, from the video you showed, both splines are visible

[@oldfarmer4700]

I got two little BX kubotas, made a little different than that one but the front drive shafts and the rear drive shafts are the weak points. Otherwise their pretty good machines.

[@Digginok]

It's a cheap easy fix though.

[@kengamble8595]

One of those times when you need to have at least three or four hands huh Frank ! 😊 If that seems to happen often, I would say it's a flaw ! Surely there's a better way they could have done that ! Thanks for sharing and take. 👍

[@Digginok]

Yes always need another hand, the repair is a cheap easy fix, so it's not a deal breaker in my book.

[@kdegraa]

Hi what are the symptoms of this part being worn out besides the wheels not being driven?

[@Digginok]

As far as I can tell you won’t have front wheel drive is the biggest symptom. Not sure what other symptoms would be

[@eliherman1708]

Thank you! Very helpful.

[@yeahokwhatever]

I'm having a heck of a Time with a RTV 500 Kubota trying to get the drive shaft out not sure if I have to go into the gearbox front and back or not any input man would greatly appreciate it

[@Digginok]

I don’t know on that model, some have to remove the bearing carrier plate. You should probably try to find a service manual. Sorry

[@yeahokwhatever]

@@Digginok I got her out. Been a min since I stared at something that long feelin like a dummy. Boots an spiders. A shifter must of rattled their teeth hard on that hit. If I tie a string on both ends I could shoot an arrow with that bent shaft

[@jimdorman1550]

Thanks. I haven't seen that issue on a L3240. Yet! But a spindle tower, yes.

[@Digginok]

I’d say it will happen eventually, the good news is it’s a cheap and easy fix. Drive couplers were around 25$ each.

[@Badgermatt-nc5nr]

Good to know! I'm gonna check my M59 next time I'm under it to see if it's the same. Thanks

[@Digginok]

Good news is it's a cheap easy fix, about $50.

[@scruffy6151]

That way they do not need to put u-joints on the shafts or make room for them.

[@Digginok]

Yep, works pretty well, $50 for both couplers and a fairly easy fix.

[@RachelJones-x6s]

M95s four wheel drive apart

[@stanbanks694]

Thanks for the help. Fixed mine today!
