    How To: Check for supercharger failure

    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
