Alternator tinware conversion

[dublicious]

Hi,

Just need a bit of help please. I am converting from a 30A dynamo to alternator. Obviously new stand and using existing dynamo/alt tinware but the alternator sits 5 min forward on the stand! I thought the tinware was compatible :/



Appreciate any help, thanks

as the alternator is a different length it needs a different mounting plate where it meets the shroud, or It would need the later fan shroud for the alternator.

and

And you will need a 912mm x 11.3mm fan belt (the generator uses a 905mm x 10mm belt). Both belts run in the same pulleys but the longer-wider belt runs a little higher in the grooves - you'll need to adjust the number of shims between the alternator pulley halves. It WILL work with the shorter thinner belt but that belt won't last - VW found they needed a stronger belt with the alternator equipped cars. To make it stronger it became wider and that means it rides higher in the grooves so it has to be longer too.

Many thanks, now to find the right mounting plate. Was trying to find an OG one.

Take care
