Kubota BX22
I was moving dirt when the tractor stopped moving. I put it in 4 wheel drive and only the front wheels turned. I took it to the barn with just front wheel power and noticed it was leaking fluid. There is a hole in the transmission case about 8 inches from the drain plug. TransDamage.jpg Is it likely to be caused from external or internal damage? If it is external rock damage can it be welded or must the case be replaced? What would be the approximate cost?

I honestly don't know, but it sure looks expensive to me. Even if you welded it, there would be a lot to prep it it would seem to prevent heat/fire damage.

I also don't know the internals, but the crack makes it look like something pushed out from inside. So does the shape of the chunk. Agree with 3R, it looks spendy. Good luck with it.

I agree that it looks like the insult was from the inside outward.

I would say a). There are a lot of days in 14.5 bilion years.

It does look to me that it was broken from the inside out - very odd. Can you pull the plug and put a light against it and look in the other hole (maybe use a snake camera/light if one is available.)

Can you see a gear right inside the case? If so, I would guess (based on past threads) that your differential lock pin broke and got jammed between the gear and the case...

The current estimate for the age of the universe is 13.75 billion years. That's 165 billion months. That's 16.5 trillion dollars, at 100 dollars a month. Current US debt is about 16 trillion dollars. So they're a lot closer than you might think!

Thanks. I did PM him the math (so as not to detract from this thread) and an explanation of why I designed the question as I did. I wanted to make people think.

Back to this topic, my message was brief, that I thought the insult was from the inside of the case to the outside, but I didn't reiterate the OP's very important comment in the first message...he was only able to propel the tractor using the front wheels. That suggests something broke away internally and was driven into the case in my view. The fact that the front wheels still drive does eliminate many parts from suspicion...we know the drive line is good at least to the point of where the power gets taken off for the front, as the speeds must be synchronized. I think the problem has something do do with rear differential. I think Aaron makes a good point/suggestion.

The OP may not be in the mood to spend money on extraneous things given the potential financial loss of the breakdown, but that hole looks like it may be large enough to get some inspection cameras through. For example, my Whisler stalked inspection camera will go through a 10mm hole. These cameras were not rated highly in some reviews, but they are less than $200 at our local Costco, so I bought one even though I already have a SeeSnake Micro.

I'd jack it up, and check for proper differential action...when you turn one wheel, the other should go backwards in most cases. See if the wheels are still linked together through proper differential action, and rotate it all about checking for odd things. It the differential is intact, you can confine the damage to the area between the front power takeoff and the power distribution to the differential.

I don't think I said I was sorry for your recent trouble, but I am of course...I hope you can reach some sort of relatively painless resolution. A BX22 may be nearly identical to my BX2200 and if I can look in my service manual and answer a question, I'd be happy to try. Many people here know these tractors VERY well.

Looks like she run aground, cap'n.
I'm thinking it looks like it hit the tip of a rock that gouged out just enough to pop a hole through to the inside. With any luck the leaking fluid washed the debris out. May be able to flush, weld, flush, fill and go ...

But the symptoms - no rear drive - makes me think EE_bota & aczlan are on the right track.
Sorry to hear about your damage. Hope it's cheap & easy to put right.
