Coming out of the HMT for the last day, cruising along stopped then started again, about 100 yards later I lost all drive. I was in 2wd. Got out looked in the back and gear fluid was under the machine all over.

Looked a little closer and saw the pinion gear had come loose and blew a hole through the transfer/rear case.

Got it home took it apart and found the cause. The end shaft on the pinion gear that goes into the coupling to the transmission had broken off inside the coupler.

Thus allowing the pinion to roll around inside the case, causing the hole

Any thoughts or ideas

I would insert pics, but I must be doing something wrong
