Crankshaft toothed pulley - reminder why it's a service item...

[lagz33]

On second thoughts i'm up for a machine cut one

[rynaqui]

I'm up for one as well..if the price isn't too steep

Iff you look closer...the notchwhere the damper comes over the timing belt pulley is flat...soo..either your 4 screws were loose...or the damper was installed wrong to the timing belt pulley..

There is a "nipple" on the toothed pulley between the (VW) and OOOO markings. There is a dimple in the harmonic damper that fits over the nipple on the toothed pulley. If the dimple/nipple are not lined up, the harmonic damper would put a twist/pull on the toothed pulley as the four allen head bolts are tightened up. Could be the issue.

I would have said thats just a marking for the front damper to be on in the correct rotation for the TDC markings on damper

[terrybullwon]

Not that the markings are any good after 20 years

Yes and no. That is so the harmonic damper (which was matched to that crank) is only installed in one particular position so as to maintain the dynamic balance that it was intended to provide due to the inherent non-balance of the inline 5. As it happens, by getting the nipple and dimple lined up, the TDC marking on the edge of the harmonic damper pulley should also be approximately correct.

Here is the external marking of the damper in action:

What happened to the EFI billet ones?

I just emailed Marc S. at efi express and alerted him to this thread.

Things get crazy about those parts.It does not need to be a space ship one,no special extraterestrial material involved.It just have to be in good shape(or new) and all things mounted corectly.Clean bolts,clean surface between damper and it,clean surface between damper and crank to sit perpendicular,good key,corect torques at m8 bolts and crank bolt

[quattro84]

You are right Bogdan but why risk it failures if an uprated version is available for not a lot more money?
It's the same with re-using o-rings and gaskets, if fine it's fine but i don't like hassle if they do start leaking.

[pasbogdan]

It is perfect to use a better one,if available.But people get crazy now about replacing them,it is like a disease.
