Belt keeps popping off.

The pic shows the tensioner spring is not hooked up to the frame at the correct spot and you are missing the belt guide at the smaller v pulley that keeps the belt on pulley.

Finally got around to where I could see the problem. Part #50 (anti-rotate bracket) was cracked and only being held together by a thread. It wasn't bent but actually cracked at the bend and became more of a hinge than a bracket. So it didn't fully break appart but flexed enough to allow the tranny to flex. After I removed the two large lug type wheels I could also see where the right side trans / axle mount part of the frame was also badly broken. I was moving fast in reverse backing into the woods so I could move a large snow bank and hit a tree stump hidden in several inches of snow. Had to completely dissasemble the whole back end AND also found the transmission case cracked as well. I can't believe the whole thing was being held together at all.

Sorry to not get back to the replies quicker. Spent a few days repairing and modifying the frame and am waiting for the new bracket and transmission to arrive.

Belt guide missing for the small pulley and the tensioner spring needs to be put in correct place at frame.

that small pulley MUST be aligned exactly with the other 2, as a matter fact you need to get down and look across all of them together and assure alignment. I bought an RZT for $800 once because the owner said it kept eating drive belts. I go it home and the engine pulley was off about 1/4 inch so I replaced it with NOS, it aligned perfectly and I sold it for $1800 a week later
