Don't despair. Use a large crescent wrench and tap off that breather nut with a hammer. You will have to use a strap wrench to hold the pulley hub from turning. Then try to use a 3 jaw puller to pull off the hub. It could work. If not, you will have to change the whole nose drive. Cost with exchange ($150), about $150.

So that hex nut should have come off before the pulling started? The ZZP instructions said nothing at all about taking that hex nut off. I wonder if ZZP would be anyhelp in this situation since if it was that nut that caused this wouldn't they be at fault since the instructions said nothing at all about removing that nut?

Aftermarket vendors like ZZP often only offer basic instructions with the assumption that a competent mechanic who knows something about what he is doing, does the job.

No disrespect intended.

Usually if you see a nut holding a pulley on the end of a shaft, you first take off the nut.

Thats ok I'm not offened by that, but I can't belive this happened. I don't have a normal 3 jaw pulley puller and a strap wrench so I'll have to wait on that. So I don't think there is anything I can do for this in the mean time. Now my transportaion is just going to sit in the driveway till I can get somethign figured out or done.

I was just re reading and re reading the instructions and it mentioned something about removing the breather plug. So now I'm sure this was my fault and I probably look like a moron now but o-well I guess. I was going to do this with my dad but he cancled on it today to prep for a big cookout he is having tomorrow so I was kinda pissed and decided I do it with out his help.

ZZP has nose drives that are $200

welcome to the club......I didnt screw mine up the same way my cheap Ebay SC pulley puller broke a bolt off in the end of the snout and upon attempting to drill it out and extract it with a thread extractor I drilled into the snout....good news is I belive you can drive it sans the SC if you take the SC belt off (if you dont mind a car thats slower than a 4 cyl Camry with a plug missing LOL).....I drove mine for a few days like that right after the belt broke (used stock belt didnt get new tensioner...boy you really do live and learn)
Snouts a biatch to do w/o removing the SC but it should be possible, as I have even less room under my hood in my Regal than you do in yer Bonne.......BTW when I got my new nosedrive I used the 20 ton press at work to press the pulley on and not the cheap puller tool (just make sure you support the rear of the nose assembly if you do this...otherwise you will drive the whole drive shaft and bearing back through to the back of the snout)


Have fun (took me about 3 hrs)

EDIT: Sorry i didn't read all the posts first, I saw right away the breather nut was still in place.

If there is a space behind the hub between the end of the housing, you may be able to a removable plate like the ones they use for removing modular pulley systems.

Otherwise, i have seen one fellow grind a broken pulley deep enough that he could then use something to spread it apart and pull it off.

In the end, all you've damaged is the breather and the pulley, you haven't hurt the rest of the supercharger.

Good luck!

Cheers,

Thats a very good idea, although I don't think I would be able to use the MPS backing plate for removal but I do like the idea of cutting the pulley down and trying to spread it.

Be very careful not to cut too deep, and remember the shaft is tapered. If you need a new nosedrive, go with www.canadiansupercharger.com as I believe they have the best prices, and a fantastic reputation for quality and customer service.

How did you do it without removing hte breather nut. Shove the tool in the middle of the nut??? The tool threads into the end of the snout, into the same threads that breather plug threads into, so you kinda have to remove it or drill a hole in it to make it work.
