Found my clutch problem

[Green Hulk]

Just pulled my supercharger and was about to throw in a new 06 spec kit and decided to stack the old spring washers next to the new ones.

Look at the difference
New spring washers on the right.

With the stack height of the spring washers reduced less tension was being put on my clutch hence the reason i was getting some slippage at high RPM's.

Instead of rebuilding the complete SC im going just throw in the new spring washers and i should be good to go.

What happened to them, and how many hours are on them?...PR...

[Green Hulk]

Not many hours on them at all. I have no idea what happened to them.

I have no idea what happened to them.

HULKAMANIA happened to them

Damn Jerry now get out there and ride.

got to thinking.... im sure the spring washers compress over time once torqued down. i decided to rebuild the complete SC anyway..... i was bored

going put it in the water tomorrow!

Did you have a correct torque number when you rebuilt the clutch and then after time this happened causing the clutch to slip because of not enough pressure on the clutch? I wonder what would cause that to happen. I mean you expect the washers to permanently deflect a lil bit but something that would barely be noticable. I would imagine most clutch failures due to normal wear are caused by the ceramic washers wearing thing enough so that not enough pressure is applied by the spring washers. You wouldn't think it would be the washers that would cause the problem. I guess thats just something to look out for.

I don't think the bad shaft/clutch was right from the factory. I had to put two shims from the get go just to build up a decent slip moment and then that still wasn't enough.

I talked to Mark about this problem and he said that the end piece where the clutch goes is pressed onto the shaft. If it isn't pressed just right there is nothing you can do to keep the clutch from slipping. I think this was one of those scenarios.

This new shaft/clutch setup holds really good slip moment with no shims.

Think i have myself a winner here

Is that something that is pressed when manufactured, or from a procedure when rebuilding or re-assmbling?...PR...

Maybe seadoo's manufacturing process is one of the causes of premature clutch failure.
