Been searching the forum for a while, but cannot find a definitive answer...What would be the issue with fitting an ABY PS pump to a 3B? Chris

I asked my friendly parts person and she says that the 3B and ABY both use the same tandem vane PS pump, i.e. 034145165 X up to L006900 and then 054145165GX from L006901 to L030000. After that, i.e after M00001, it was 8G0145165 X. The real difference is the 3B and ABY use different v-belt pulleys, i.e. 3B = 035145255E (also 7A and NM) whereas the ABY pulley is 034145255.

Here is some PS pump info (intended for AAN owners but might be useful anyway):

Should be able to swap the pulley by undoing the 3x allen key bolts

My memory might be off, but I think you might need heat too to take the pully off.

Depends if it's been off before if it has it will pull and wiggle off

**Error404** · 28 September 2011, 21:36

easy, use a puller, its an interferance fit

Ah my bad.

Are there any physical differences between the two, is the pump body the same and just the pulley thats different?

ADU/ABY/AAN/3B and even 1.8 four cylinders of the late Audi Cabriolet have the same pump.

Pulleys could be different

Cheers for that

I believe that pump is a single vain pump.

Part numbers seem to match up also the pump looks identical to the one on my car.
