Timing belt problem

Postby vip09 » Fri Apr 14, 2006 4:25 pm

I'm having a problem with my timing belt. It wants to move all the way to the inside of the pulleys and it is rubbing on the the motor. Is my tensioner possibly bad?

Maybe - did you get a new one?

Also look down at the drive gear on the crank and make sure the flange side is towards thhe block and not away from it.

Post up some detailed pics of the pulleys, belt, and belt area.

I have the same problem...someone told me that since my belt was new it needed to create a wear pattern...but I am going to check that washer with the flang.

I'll get some pics up tomorrow. I didn't replace the tensioner or the no. 1 pulley. I did replace the no. 2 idler pulley.

I remember when I had the engine on the stand and we were getting the timing right.. the belt was moving towards the inside like its doing now. So I tried moving the belt back towards the outside on the top of the cam gears.. i'd turn the crank, and move the belt over, etc and kept doing that until i got all the way around. But when the belt would come to the num. 1 idler pully by the tensioner it would want to go back towards the inside of the pulley again. I spent an hour doing that, but when the belt came around to the tensioner pulley it would want to go back towards the inside.

I replaced the no. 2 idler pulley as it was worn very bad. The no. 1 idler is the original one.. i didn't replace it.

Already replied to ya on NC.org - any chance we could get a few more pics of the tensioner, idler and cam gears but zoomed out just a tad from these ones?

Also any luck checking that crank?

Not sure if anything is bent... it looked alright when I bolted it to the block. I never removed the tensioner pulley from the assembly. Here are some pics.. this is as good as I can get with the camera.. I just can't squeeze it into those small spaces.

There is a sort of washer you put on the crank pully that keeps the timing belt away from the engine. You can easily install everything without it and im guessing what you have is the result.

The top picture looks like the crank pully, and i dont see any washer on the inside of the belt. Ill see if i can find mine.

edit:
oh no wait the washer goes between the timing belt and the other pullys, the other side just has a ridge. I guess your timing belt jumped over it? if so it must not of been tight enough.

could be - just take teh 2 12mm bolts holdint the tensioner cylinder off and then pop that idler off. While you're at it order a new T-Belt

I would definetely say the spacer on the crank gear.. I did almost the same thing, except I put it on facing the wrong way.

In case anyone is wondering, timing belts only last for about a mile when your a moron and put this spacer on backwards.
