    Question supercharger rebuild 2007 RXP question

    Hello all, I have a particular question for those that know SC rebuilds like the back of their hand and have seen it all.

    I did some reading and determined that my ski was not boosting so I pulled my intake hose off and easily spun the SC impeller with my finger which lead me to pull the SC out. This is the first time I've held one in my hand so I am not sure what things should look/feel like. What I found has me concerned. I noticed that there are 2 washers (one on each side of the gear), however, the gear itself has a huge amount of lateral play. In other words, you can slide it on the shaft in either direction as the gap is big enough to fit another whole washer. Is this normal? or was something there originally and has since worn completely off or worse, broke and its remnants made their way into my engine?

    My hope is that either things are just loose from wear and tear (and it just needs a rebuild), and not that something broke off into the motor. I want to send the unit in for rebuild but if I also have to pull my engine, I'd rather not spend the money on the supercharger right now.

    Thank you for your response ahead of time!

    Post a picture of it but sounds like you lost a washer and seeing it is 07 and not knowing if the SC has been rebuilt it could have ceramic clutch washers. So post a pic for the gurus to give you a better idea of how bad it might be

    Yep, lost a washer, the engine will have to be disassembled and flushed of all the pieces of the washer. Both oil pumps are probably trashed. Also check the timing chain for damage.

    By the way, I also inspected the needle bearing to make sure that ALL pins were still there - and it seems to be all there

    Thank you for the reply, I really appreciate your help.

    I'm still confused about it though... in this pic you provided, it shows you have exactly 9 parts (starting with the nut) to the first clutch washer (it being the 9th part). I have the same number of parts.. My gut feeling (again, not knowing much about these superchargers) is that a) the nut loosened and the gap increased, or b) the spring washers flattened out a bit and increased the gap. I looked at a schematic and it seems to have all the parts in place - it's that large gap that throws me off

    Well, I think I just figured it all out! and yes, I'm screwed. I am almost certain I'm missing the compressor side clutch washer. What was throwing me off is that the engine side washer is still intact and on the compressor side there is a collet on the shaft that looks almost identical to the washer so yah....

    What's next then? pull the motor and tear it apart?

    He is missing one clutch washer! The one to the left of the gear.
