Re: 3.4L DOHC Timing Belt walking off



I don't know your setup, but on lots of engines that means the harmonic
balancer on the end of the crank has failed. It has a rubber ring that
can allow the bottom pulley to become out of line when it fails.

All,

Have a 95 Olds Cutlass Supreme, 3.4L DOHC. Timing belt is walking off
the cam gears, grinding against the cover and shrinking in size.

Questions :

1. What makes this happen ? Idlers & tensioner replacement needed ?
2. Can i mark the CAM gears and crank, remove the 2 idlers, 1 tensioner
and then replace the belt ?
3. What kind of belt is good ?
4. Mechanic wants to charge 1000 to replace..is that a decent price ?

Any other helpful comments/suggestions ?

thanks,
.
