This explains why crankshaft pulleys are so expensive! 8-) Also a good reason to only buy new ones, unless it's possible to repair old ones to be as good as new? I saw a new one on Ebay recently (probably for a 16V engine - mine are 8V so I think the pulleys are different) which was priced over US$100. >Replacing it involves removing the belts, maybe moving the AC compressor aside, >blocking the engine flywheel so it can't spin, and getting the relevant nut >loose.

Could be better just to go whole-hog and remove the engine from the car to do this sort of thing. That way it's a lot safer, and it allows other things to be done to the engine which may be possible with the engine in-situ, but are much safer and easier to do with the engine out. Opinions?
