Big Problem! Now Solved
« on: 13 January 2014, 16:44 »
Cambelt pulley on end of crank is wrong!!!! :angry:

The diesel crank has a flat section whereas the 16v abf has a notch in it.
The diesel pulley has less teeth so the cam belt wont fit it!

Makes me wonder as if you read the forums ClubGti etc. many people say they have done the same engine conversion as me but they dont have the same problems!
They telling porkies or have kept quiet about the problems????

Anyway think I need and engineering shop with a milling machine!

abf crank pulley is 26 teeth and the diesel 22 (I don't know if that helps in any way?)

also abf timing belt has number of teeth 151 and width 25mm

Cant!
Wont fit the camshaft pulley nor the secondary pulley that drives the oil pump!

No it doesnt help!  :grin:
I just found that out today!
The real problem is how they fit onto the end of the crank itself.
I cant see any way round this other than getting the abf one machined to fit!

don't think there is a right one when you fit a diesel crank into an abf block.

I would machine the crank as if you take any metal off the pulley it might weaken it.
