Hi - am looking at getting a new one from vag for my turbo.
There are two part numbers - early and late.
The earlier one is slightly smaller. Presume this is like ones on mk2s (and therefore might have timing markings corresponding to a g40 pointer - as they are based on a mk2 engine) and will use a smaller belt.
the later is bigger and is as fitted to a gt,uses a longer belt
I'm tempted by the smaller (and therefore lighter one) but im not sure why they changed it???? anyone know?
I thought the early and late was square tooth and round,
Double check there both round too..
i mean the auxillary crank pulley - that drives the alternator
oops ..... :$
Was there never a deviation between alternators running different power outputs?
possibly different sizes for the different Amps ... could be rattling of horse crap tho ..:D
Just make sure you match the alternator pulley diameter to the crank pulley.
