On my last engine, I could never get the belt straight - don't know why. You can shim one or other of the pulleys out. Shims are available.
@snotty .... Should there be a certain amount of back/forwards movement on the altenator shaft without the pulley fitted - 3-4 mm ?? Seem to remember some thing along those lines but mi memory ain`t what it used to be ...
Ahhh yes - forgot about the fan shims !! I found an old one whilst having a dig around but no fan on the back . That has 3-4mm of movement so might be worth looking into getting it up and running as a spare
I'll be fitting mine tomorrow hopefully, so will also be able to have a look if any movement in the alternator shaft.
Fitted the new pulley today. All seems okay. What is the best way to stop pulley rotating whilst I torque up the nut. Cheers
Like Snotty says, or read your owners handbook if you have one, the procedure is in there. The original tool kit had a screwdriver to jam the pulley from turning and the wheel socket spanner to tighten the nut. Tony
There have been different top and bottom pulley designs over the many years of VW production. Alternator and Dynamo designs too. Ive seen T3 top pulleys on T1 engines before. The position of the fan housing (on a type 1) in relation to the block can also vary a few mm forward or back and even the crank in the case changes position a little.
Might have been the case with my old engine. No amount of fan shroud or alt stand shuffling could get them to line up. Drove me nuts. In the end, I shimmed the crank pulley out by a few mm.
