3-Point Hitch Broke my PTO Differential Gear Case. Bearings shattered!

[V7Sport73]

So, about $800 dollars and 20 hours later everything is back together and working again. The only problem I had was the back PTO cover. I struggled a little bit trying to get all those brand new bearings and gears installed corrrectly. I must have touched the silicon because I have a very slight drip coming from the back cover. I decided I'd run the chipper and break in the parts for a bit before resealing the cover. The good news is that it's easy to get to and will only take about 30 minutes or so. All the other seals held fine. So attached are some parting photos of my B3200 chipping away.
Even though it's not the chipper the broke everything, I have a photo of me shorting the PTO shaft for the chipper just to be safe!

Glad you got it finished. I still can’t believe it was that cheap to fix it.
I bought a tiller for my B2650 and the shaft was perfect with the quick hitch. If I were to take the quick hitch off i would have to shorten the shaft though. I need to keep that in my head.

The shaft is pretty easy to shorten. I used a my reciprocating saw or "sawzall" if you will, with a bi metal cutting blade. Less than 10 minutes from start to finish I was done. That includes measuring, marking and cutting. Well worth the effort and peace of mind!

Sometimes on smaller tractors the shaft length is critical. Too long and we see the result. Too short and the shaft pulls apart.

In your case paranoid caution should prevail. Do some critical measuring to make sure your shaft doesn't pull apart thru the entire range of the 3pt. You've already learned the longest distance is with the 3pt raised.

Excellent work on your repair!!!! If all you got was a small drip you did very well. Thanks for posting this thread and the photos!!!!

Agreed. General rule of thumb is you want 1/3 the length of the shaft minimum inside each other.

Thanks Richard. Everything was really tight on the PTO assembly. So I figure I'll run it for a while and everything should slide back together again much easier.

good job! I say you just park that leak over that pesky weed until you you find a "roundtuit".

Go to a Yamaha dealer and get some Yamabond for sealing motorcycle cases. Great stuff.

Excellent thread and documentation with quality workmanship. That's not really all that expensive for what could have been much worse.

What happened was the implement came down fast and with force and the PTO shaft poked the back of the tractor in and broke it that way. I've done this before and only ruined the implement and did not damage the tractor. It still cost the same money, however. This thread should be required reading for all new tractor owners.

Besides the Kubota dealers Three Bond 1208D I have used the generic one used on ATVs from WSM .
