hey guys. I've searched and only found one other thread on HOW TO do a pulley swap

I'm wondering if this can be done with the supercharger still on the car? The thread said one part was to remove the S/C. I'd rather not if I didn't have to.

I've got the STG 2 pullet on and I'm going down to a 2.8" ZZP pulley.

Can the swap be done with the S/C still on the engine?? IF SO.. how??

Thanks!

 

If you bought the ZZP pulley that will fit on the GMS2 hub you shouldnt have to take the blower off.

 

OK.. but any suggestions on how to hold that dang thing tight while trying to break the seal that GM puts on them stupid bolts??? lol I know he loc tighted them biznitches!! lol

 

Hmm. I've heard that some do that. My dealership did not do that to me.

Well, leave the belt on for sure until you loosen the bolts. That should hold the pulley tight enough. I always loosen the bolts before I remove the belt.

 

I have a pulley that I think gm put on, its off the blower and those bolts are a biiiiitch lol.

 

If they're not loc-tite'd, they should come out with very little effort.

If they ARE loc-tite'd, DO NOT just try to gorilla them out. The mortorq bits WILL break. lol

You're going to have to heat the bolts with a propane torch or equivalent heat source in order to heat the bolts up to red loctite's 400F spec.

I wouldn't try that with the blower on the car though. This is probably why you've read conflicting suggestions on whether to remove the blower or not.

 

OP: If you do have to heat the pulley please be very careful, and take your time.

 

Thanks guys! I'm hoping that they come off easily.. Heat is gonna my my final option.. lol
