How to change Procharger pulley Hey all,
Let's pretend that I'm stupid. Okay, now let's pretend that I don't know how to swap the Procharger pulley. Does anyone know where I can find some instructions on this just in case this fiction ever becomes reality?
I've got the blower mounted, and I've got a hex key on the intake side and an end wrench on the pulley side, and I'm giving it a little tug, but I'm afraid I'll mess something up. Is there another way to lock this thing up so it won't turn? Is there a torque rating for the bolt when I install the new pulley?
Thanks in advance for curing my fictional stupidity.

I've always used an old belt, tightened it on the pulley, and grabbed onto it with big pliers or vice-grips. This holds the pulley in place to crank the bolt loose.
When I reinstalled the bolt, I used red Loc-Tite (medium strength) and torqued it to yield as much as it would hold with the belt trick.
I spin my engine to 7000 RPMs and maxed out my blower at 68k RPMs for years, and never had a problem with the pulley coming loose.

I think I'll try the belt trick, but I'll go with a belt wrench in the future so I don't have to do it in the car.
Thanks for all the responses, guys.

I've tried this with no luck. How do you guys prevent the entire unit from moving around? Even trying to hold it down with one hand allows too much movement to break it free.

Tried a air gun with no success, and was worried about possible damage from the sudden force.
I had to get creative when taking mine off. The entire screw was covered in locktite... and the pulley/shaft also had loctitie on it. Had to use a combination of a old belt, vise grips, and a vise to get enough leverage and hold the entire assembly down.

I removed the entire head unit and used a impact gun to get the bolt out. Worked like a charm! then I used a propane torch to heat the pulley up and then pried it off with a large screw driver. It only took a few minutes.
KS91Z28 - Hmm didn't think about heating it up and then hitting it with the impact.
30th t/a - I wouldn't recommend using a large screw driver to pry it off. I would expect damage to the seals by doing this.
'Trust' - Ended up getting a 3.0 Richard Racing pulley. Adding a larger air filter and going to pressure test the tubes to check for leaks.
