Supercharger Pulley Won't Come Off!!
 

I'm doing a SC Pulley replacement. Using the loaner tool from Webb Motorsports just for the stock pulley, and a crowsfoot puller. The pulley WILL NOT come off. I haven't broken the crowsfoot YET, but I obviously need a trick (and a prayer?!) before I do. I've tried a little heat (a little, on the pulley)...nothing. Tried a little penetrating oil...nothing.

I saw a thread where the pulley was cut off...with a steady hand on the air-powered cutoff wheel, using it at an angle, I suppose that could be done, but surely there is a better way. I searched the archives, and didn't come up with a definitive solution. HELP anyone?

It'll pop eventually. How old is the SC with stock pulley? What kind of tourque are you laying down now with the pulller?

Your pulley might shatter or just break apart. Then you'll have to cut the aftermath off without damaging the shaft. Good luck.

I've applied enough torque to bend the crowsfoot bolts (the outboard ones that attach to the custom puller tool...not the center puller bolt). I've even used an impact wrench on the puller bolt...and yes, I have a bolt in the end of the supercharger shaft.

Thanks...any other ideas?

Go buy some grade 8 bolts for the crowsfoot bolts then. Tourque it till it pops or breaks. Keep up with the heat(the cast pulley should expand at a faster rate than the shaft).

Could you heat up the pulley only, causing it to expand, and hopefully pull off?

Be careful to not heat up the shaft...

That's what we did. It was stuck so tight we thought it was going to break something. After a torch on it for a minute it slid right off.

I'm the guy who started a thread back in August about having to grind the pulley off. That was a pretty ugly pulley install. :(

Is the center bolt from the puller actually threading *into* the hole in the supercharger shaft? If it is, that's your problem. You need to put a sacrificial bolt into the end of the shaft first, so that the center puller bolt doesn't thread into the shaft and bottom out.

SUCCESS at removing SC Pulley
 

Thanks for the confidence-building posts...I got SHORT Grade 8 bolts, and that seemed to be the key. Took about 30 seconds with the impact wrench before it popped! Whewwww...what a relief!

Your luck held. I understand that from a technical perspective a pulley change is a simple operation, but the nail-biting stock pulley removal process is the one thing that will guarantee that I get it done at a shop--as much as I would not want to waste money paying someone to do something I should be able to do myself.

Good for you! What a feeling right!?
