which crank pulley for a g40 turbo

[PeteG40]

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

[djtez]

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 ..

Just make sure you match the alternator pulley diameter to the crank pulley.
