How To: Check for supercharger failure

[Green Hulk]

When you pull your supercharger and you see a gap like this between the spring washers you know it's time for a complete rebuild



As the clutch wears the spring washers "spring out" in an effort to keep tension on the clutch assembly. As they spring out the gap gets bigger.

In the case of this supercharger the spring washers were at their limit and there was basically no tension left on the clutch.

One of the washers wore deep into the gear


This is what a good gear looks like. You can still see the 4 oil grooves.


This is the worn out gear


Here is the worn gear on the left and a good gear on the right


This clutch slipped for a long period of time which eventually wore out the needle bearings and the shaft.

sc failure....

Hello, I'm new to this site and wondering if someone can answer a question for me. My 2005 rxt all of a sudden was only doing 50 mph and 6000 rpm and was only 2 min away from the ramp so I went home and removed the supercharger, sure enough the gear was spinning freely on the shaft { from my understanding this is not a good thing} lol
My question is when I stuck my finger in the the engine case and felt the gear that the supercharger if powered from doesn't seem to be smooth all the way across. If I run my finger along the teeth it is smooth then a little step up is that normal ??? does anyone have a picture of the gear inside the engine case that powers the sc ????

Thank you all

There are actually 2 sets of teeth on the flywheel. One is for the SC and the other is for the starter. If you use a mirror and flashligh, you can see the teeth. If you still have the ceramic SC washers, you need to get them out asap... Ron

If you have no records I would assume the worse, you have ceramics and need to replace them. We rebuild the sc at 100 hours but since you are close and have no idea how it was ridden I would go ahead and let Jerry rebuild it with whatever is necessary....then you have 100 fun free hours left.

I'm sure they have....pm Jerry, Green Hulk, and ask him what to do.

[black96jetta]

wow awsome site and thread. learn something about how the clutch, washers look like. 10+++ will for sure take the SC myself and send it to Jerry. NO mechanics needed.
