Hello fellow StoveBolter's,

I recently rebuilt my GMC 270 water pump from a kit via Fleabay. Regrettably, I destroyed my water pump pulley while disassembling the water pump.

Can anyone recommend a source for a 3/8inch drive belt pulley? Are there any interchange options I can use from a Chevrolet, per chance?


What is this and what does pulling it out do?
