Need a v-belt analysis from an expert. I put a new electric clutch on my Cub Cadet and now the belt from the deck turns itself 90 deg onto this pulley. It does run a while that way but wears out faster than it should. Straighten it and it just flips to the side. Could it be a strange pulley angle. Same belt as before. 2 belts have done this now.

Al,

Don't claim to be an expert, but sold a lot of auto parts in past life. Snapper used to spec a belt with a cross section shaped like a stop sign - sort of a back-to-back v-belt for the contortions on top of the deck with all the pulleys. Is something like that required for your application as well? Put another way - are you sure you have the correct belt?

Good luck,
Braxton

Also check the bearing assemblies for looseness. That turned out to be the reason Dad's Cub Cadet ZTR was throwing the deck belt.

Well I finally have it running w/o twisting itself on the clutch pulley. I installed a 95" belt instead of the spec 96.5" ones. It pulls tighter w/ no slop to contact other metal parts of the deck like the other ones did.

Is there a tensioner pulley as part of the belt arrangement? Tensioner is intended to take any slack out of the belt. If there is, the spring may have lost strength.
