Hello,
I just put a new timing belt on because my last one ( a few months old) shredded. It now looks like my new one is doing the same. It looks like it is rubbing against the block and badly against pump. I made sure to try and center it on the pully's when I installed both of them. Any ideas why this is happening? Thanks -------------------- 1st car- 1994 Celica GT 2.2L 5s-fe SOLD

We noticed tonight that the belt was moving as it went around the tensioner. It just bolts to the block, or am I missing something that would cause it not to set flush? -------------------- 1st car- 1994 Celica GT 2.2L 5s-fe SOLD

there is an alignment pin for the tensioner if you dont have it in the hole on the tensioner it will cause it to sit crooked.

yeah it bolts to the block but if your not careful it can sit a bit crooked.
if the belt is moving then something is make it move obviously. Check the idler too. -------------------- ST205 Group A Rallye GT-Four, #61 of 77............600hp GT3582r

you may have warped pulleys (from age and high mileage) and may need to replace them.

I've seen this happen once before on a 3SGTE. There is a thick washer behind the tensioner pulley (between the pulley and the block) that was misplaced. Without it there, the belt kept pulling in towards the engine and shredding itself.
