    another sc washer slip question...

    I had GH install washer on my sc over a year ago....at that time the sc had maybe 70 hrs on it. Now my sc has 170 hours on it.

    At the end of last year I completed my rear air intake...only ran it once...then put it up for the winter...I was all over the limiter...didn't know it. This spring I got to tweeking that air set up and ran the ski a few more times...also on the limiter. After deciding that a taller prop was in order I put one on....the weather started warming up faster than I could test though and I lost my base line...long story short...I gained speed but at the same time I lost 400+ rpm's.

    Now...I know the prop needs to be tweeked...and it will....by a pro.

    How likely is it that my sc washers are slipping and they're contributing to my loss in rpms?

    I would say very likely with 100 hrs since last shimming.

    Remove the intake to the sc. Put a torque wrench set for in-lbs on the supercharger wheel and move it. The gear will slip on the washers at a certain torque. Check the torque wrench for the slip torque. It's perferred to be between 70-120 Inch-Pounds. If not it needs shimming or rebuild of washers and spring washers. Jerry recommends rebuilding at around 100 hours but if you don't ride really hard you could probably go to 150 hours. IOr you could remove the sc and check it in your vice.

    The whole sc....actually Jerry has a sc holder plate along with a gear holder that the sc bolts on to hold in the vice. The gear holder holds the gear while you use the torque wrench to check the slip. I have done it my just sitting the sc on the workbench, wrap a shop towel around the gear and hold with large channel locks while checking the torque. The safest way is to buy the holder and plate, bolt it up in the vice and check it. If you have to replace parts it's already on the plate and easy to work on.
    Here's the holder tool:

    With these you can do all you need to sc except main bearings.
