Reinstalling PS pump pulley - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I bought an installer kit to reinstall the PS pump pulley but it appears the internal threads in the pump shaft that the installer screws into have rusted away to nothing.

I tried just banging the pulley on for a short while but that didn't seem smart or successful.

Any other ideas before I buy a new pump?

Run a tap through the threads to clean them up. I do that all the time.

what size are the threads? The installer bottoms out without engaging any threads.

Driving or pressing that pulley on is a nono....it'll break the internals....always use a installation tool...
