Some time back had a go at getting the bearings and seals replaced in some pumps. I may have one knocking about still. I'll only have one with the standard fan/pulley attachment - some B20Es have funny bits for the viscous fan.
Alternators less easy. Used up a few recently. What's happened to yours?
