My Supercharger idler pulley bearing has gone out. It makes a bad grinding noise when ran, kinda like a loud hiss with a slight whistle. There is play (front to back when pulling on belt) in it so I am pretty positive it is the bearing. So my question is what type of bearing is in there? Can I pick it up locally or do I need to go through Alpine/Tone.
Thanks in advance,
Alan

NSK bearing part # 6301C3, the C3 means high speed. Found it in town!

Any idea what the sealed bearing that fits the nose cone is?

No idea, but a quick phone call to Alpine and you can find out.

$300. Ouch. I have two nose cones already, another $300 for an experiment isn't worth it to me. Maybe once someone near DC gets a supercharger with the updated nose I'll reconsider.

My idley pulley bearing siezed, and it threw the SC belt.
The pulley has a little bit of damage from this, but nothing I couldn't clean up with a pass in the lathe. I tried to get a stock replacement pulley, but no chance of that.
Looking under the hood of my friends LS1 C5 I see almost the exact same pulley. Same diameter, same number of belt grooves. I bought one at the local parts place for $18. The new pulley is glass filled nylon, and at least a pound lighter. The bearing also has a slightly bigger hole, and a bit more backspace.
I made up a new reducer bushing with more backspace to compensate.
I still need to make up a new front retainer/dust shield. More pictures in the next few days.

Heres all the pieces left of the original idler pulley.
New pulley and backspacer on idler shaft.
The front reducer and bearing dust shield. I added some ribs to this for some pizzaz.
It gets reinstalled this weekend.

And another?
Could you draw it up and get a shop to make 10?
Nice job.
Thanks, Roy
