Hi Dave

It's the other way around ... it goes TOO far. It goes all the way to the rear pulley but that leaves the front of the damper pulley PAST the front edge of the crankshaft ( @ 2mm ). I do have the large spacer/washer that goes in front of the bolt but it's just tightening on the end of the c/s and not the front of the damper pulley.

Hope you are well mate

If it's going in too far, that suggests to that the pulley hole is either worn or not the correct size. Is there any way you can check the internal diameter of the old one with the new one?

I must be honest that I don't see that this has anything to do with the crankshaft timing belt sprocket at all.After all, there is an oilseal in the timing coverplate that goes between the two items in question, so it's not as if one butts up to the other, they don't. Unless my memory has gone completely up the spout!!

My crank pulley has no spacer, just touches the cam belt pulley, I think the o/p's problem has been caused by the failed crank pulley fretting on the shaft and not only worn the keyway out but also worn the cam belt pulley down a bit too. The presence of metal dust in the cover backs this up.

I think a spacer will be his only option now as the cam pulley is well stuck on so will need cutting of or the crank dropping.

Dave0974 ... that's it exactly

Dave ( thebiglad ) the seal on the timing front cover actually sits around the rear outside diameter of the damper pulley. The back of the damper pulley does push up against the front of the toothed belt pulley. The belt pulley is concave and the rear of the damper pulley fits in that ( or at least I think it does ).
