Default Slight Pulley wobble OK?

Mine doesn't shread belts or anything, but after seeing some of the threads on the idler pulley issue I looked at mine and it had a slight wobble.

Anything to worry about? It didn't have a any bolts backing out that I could see. I assume this could be address during a CAM install?

I think your talking about the crank pulley? the idler pully is totaly different, that being said, nothing is perfectly round,Gm does'nt waste time/money cutting surface's that don't matter, you don't say if it's an 05 as these were most effected and YES if you have an issue, during a cam swap would be the time to look in to it

And, if you're going that far in mods, then you might as well install an underdrive pulley at the same time......don't forget to use crank pins, too, here's what I have.....good luck!

No problem. This is normal on LS engines.

I would not bother with it over a small wobble, but if you do a cam install I would go ahead and get an underdrive as noted above. We have a special on the Powerbond underdrive pulley, both new belts, and a replacement crank bolt for $199 plus shipping
