2004 supercharged grooved pulley

[Seca750rider]

Hello all !
I seem to have a problem finding anyplace or dealer that can find a part number for me. The grooved idler pully blew apart on my grand prix. I have the replace pulley, and belt. Yet there is a bushing which rides between the mounting bolt and bearing. That's the part I need to finish the repair.
Any help would be great, Thanks.

what pulley number? i know of no bushings

 

[Seca750rider]

Scottydoggs, The pulley number is 8. The bushing is appx 11/16" O.D. x 3/8" I.D. length is unknown because most the the old bushing is gone.

you mean the bearing inside the idler pulley? you buy a new pulley, comes with the bearing.

Sounds more like he is talking about the washer that goes between the bolt head and the bearing on the new pulley. He lost the washer when it exploded.

Something like this.

That's close, FiveFinger.
I have the bolt and washer, and the new pulley. On my car, the bolt has a bushing that the new pulley/bearing unit rides on.
The i.d. on the bearing is 11/16" the bolt is 3/8". Said bushing makes up the spacing difference between the bolt and pulley. If I could figure out how, I would post pictures on this thread.
Thanks, Seca750rider

What year? (edit: nvm I see it in the title, duh)

I have an L32 and can assure you, there are no bushings of any sort on either the smooth or grooved pulleys. There are dust caps. One won't fit with certain aftermarket pulleys of the same type, though.

I'll be out there today and post back if ..if, I find any bushing. I've been wrong before, so.

Went out and checked. There's a thing on the bolt under the dust cap. Bolt is GM 24508425. There's only the problem of that they don't make it anymore.

You'll have to find one in the junkyard, I'm afraid.
