300tdi timing belt change question - reseating crankshaft gear correctly ?

[Andy130]

hi guys,

Doing a 300tdi timing belt change for the first time - also had to replace the o-ring and seal behind the crankshaft gear due to a leak there.

Now, i'm not sure if there is a method required to 'reseat' the crankshaft gear to the correct depth? Should the crankshaft gear line up with the idler and tensioner pulleys if it at the correct 'seated depth'?

The woodruff key goes back on just fine, but it seems to me the gear itself might be sitting a few mm proud.

Is there a process to ensure that the crankshaft gear has been driven in properly? I seem to get ' bounce back' from the o-ring, i'm not confident i've done this correctly.

Thanks all.

The crank bolt will secure everything once you have the harmonic balancer on, there's enough width on the crank gear that it won't effect your tension.

Awesome Rick, thanks mate.

I've never been able to get the o-ring to seat itself in the crank gear recess, even after tightening the hamonic and nose bolt. I resort to fitting the o-ring into the gear before working it over the last key with difficulty.
