Mk2 8v - Removing crankshaft pully wheel for belt change

The pulleys 4 holes are all asymetrical so it will only go on one way, and if you have the lower black plastic belt cover on, you will need to take the water pump pulley of to get at it - or cut it of if your a bit pikey.

 

It was possibly cut, the alternator belt pulley on the water pump has a too close a gap to the intermediate shaft pulley to allow the cover to be taken off. PAS pulleys sit on the outside of this pulley and don't really get in the way.

 

Come to think of it on some cars (a K Jet of mine, and possibly a simular set up to the one you worked on), they only have 2 pulley's for the alternater, one on the crank and the other on the alternator this might then leave enough room to get it off. But on most of the cars i have owned they have a third pully on the water pump, it has less squeal when wet.

This pic shows it with the third pulley on the water pump. A bit of topic here.

 

I think older cars have bigger pulleys... I've had to swap them over in the past when changing engines from different ages. Don't think you need to take the water pump pulley off on a later car, assuming it's still got the original one on, of course.

 

And for PAS/Non PAS I'd think. Actually... the larger pulley might just be non-PAS cars... the older engines I used were non-PAS.
