What kind of pulley is this? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Lemield · 07-22-2010, 10:20 AM

I have never seen a crank pulley like I have on my truck. Can anyone tell me if this is stock or what??? Any help appreciated.

I am planning to put A/C on the truck (still deciding which kit to use).

It's actually a two piece unit.
The one closest to the engine is stamped steel, and it's just a single groove model.
The one closest to the radiator is of cast iron, and from my experience has been added for AC or other stuff.

I have one just like it, but I have the two groove stamped steel pulley.

Wow Vectorit....that was FAST! Thanks for the info. I'm guessing, based on your response that if I got a two groove stamped pulley to replace the single, I could then use the middle groove for an A/C compressor and then I could still use the bolt on inner groove for my PS pump.

man, im not good with the short water pump stuff

I've got the same pulley on my 68 GMC with the 396. Aftermarket AC.

I have that pulley on my factory AC truck with a 350 and PS. My water pump pulley has 3 grooves though.

48richard · 07-22-2010, 11:54 AM

I had the same set up, and when I put in AC I replaced the single groove pulley with a two groove, and put back the other two groove that I already had, so I had four grooves.
One closest to the block is alternator, then AC, then unused, and then PS

Are you looking for the single groove stamped pulley? I have one that I took off my engine.

Old threads have a lot of good info in them. I like seeing them resurrected now and again.
