Thanks B2.Today I went to the junkyard and bought a used supercharger.The pulley movement is smooth.I will start a post in the appropriate forum when I have the two gaskets,injector o-rings and the 2 o-rings for under the supercharger.It took me about 30 minutes to remove this one at the yard.I had a couple of bolts that fought pretty hard.I paid $45 for this one,also picked up a used MAS just in case.Tim

What year did the supercharger come off of? I hope it was a 91-93.

It came out of a 92 that had 140,000 miles on it.

Good. 94/95 won't fit yours.

You need a full rebuild on that with those miles. Both nosedrive bearings, the ND seal, and both needle bearings in the case for the other end of the rotors. Do a coupler at the same time.

I thought you would say that :( ,ok,I will order the rebuild kits as soon as I can.I was also thinking that it would be a good idea to do the LIM while I am in there.

Thanks for the advise Will,your dedication and knowledge with these cars is remarkable!!

I think you could get away with just a coupler change. The new SC fluid is a given.

The bearings should last a lot longer based on your mileage.

When you remove the nose from the SC to change the coupler, you can pull out your rotors for a good inspection.
You can purchase a small quantity of the very special synthetic bearing grease from Intense and add a little to ensure lubrication.
You will also be able to see how clean or if contaminated.

Paul, we're not talking about an M90 here. The M62 spins faster than the M90 by a good margin, and they wear out faster. 140k miles is already beyond the rebuild point for a 62. His supercharger has spun 30% more revolutions than an M90 on a stock pulley would have in the same miles. It has also suffered from more heat stress.

If he does it now, he can take his time, otherwise he'll be pulling it AGAIN very soon. Do it right now, and never worry about it again.

So maybe you should prepare to change out bearings on Grizz'* SC at WCBF this year.

.....if it lasts that long.

Over the weekend I cleaned the IAC and the MAS,and the car now runs without dieing.I pulled the #1 spark plug and it was very black.I drove the car to the gas station down the street to get some fresh gas in it since it has sat for 4-5 months and was below empty.I will do a complete tuneup,plus coolant flush after the supercharger install is done.Tim
