Return PolicyThis Offy alternator pulley is designed to fit on a GM alternator and is retained by a washer and nut. It accepts the standard 1932-38 flatheads with the single 5/8” belt width and allows you to bolt on an original style 1932-38 Ford fan.
Note: The powergen uses the same shaft size as the GM alternators and this pulley should work without any problems.

What fan will fit this pulley bolt pattern? My current fan bolt pattern does not match this pulley. I don't see a bolt pattern on your steel race fans, which is what I have now. Now that I have the Power Gen and this pulley, I need a fan. What do you suggest that fits it?
