    Shim install

    I just installed a shim & I went from 8.X ft lbs slip to 23+!!
    I took it out & rechecked the slip & it was 8.X again (between 8-9)
    Put it back in & got 23+ again.
    What gives?
    it's installed like this: )()shim() torqued to 22 ft lbs.
    Do I torque to get the slip needed or is it always 22 ft lb?

    When it is out of the ski, are you holding the gear or the nut to check the slip? It sounds like you are holding the nut. You should be holding the gear.

    LOL,
    The sc is out. The gear is wrapped in a cloth & put in a vise. I'm turning the SC wheel counter clock till it slips. I took the shim out & torqued to 24 ft lb & now I'm at 9.5+ ft lb.

    I've played with the shim location & switching around the spring washers. I get 22-23 ft with the shim between washer 1 & 2, 25-26 ft with the shim between washer 3 & 4, Then I get 29 ft with the shim on top between the last washer & the big washer before the nut.

    I just wanna know why i'm getting up to 18 ft lbs more with the shim.

    I agree, that is the nuttiest thing I have ever heard. Anytime I ever added a shim there was only like a 3/4 pound or so difference, but I also found that my coated washers were toast. It just really sounds like something is hanging up though....

    if the spring washers are toast no matter how many shims you use you will not get the correct tension....they act as a spring and if the spring is worn out then it dont matter...slip will always be incorrect...i think the shim is used for when the gear, washers are a little worn..to make up the lost thicknes.....at least imo....

    got it!
    Thanx jerry.

    The spring washers are 64 hrs old. Hmm, got me thinking, should I have replaced the spring washers first?
