    max number of shims on fresh rebuild

    i have a riva s3 supercharger and have installed a brand new rebuild on it also. after 3 hours of riding i was experiencing slip.

    i checked and it was at 9 Nm.

    installed 2 shims and bumped it to 11Nm
    it worked fine for 3 hours and now im experiencing slip again.

    can i install more than 2 shims?

    i dont want to wait for mcmaster spring/washers unless i absolutely have to

    thanks

    i put them in between the smaller part on the spring washers so i get contact; just like it has to be. i saw a good change in slip, but still not enough to hold a s3 charger. i read that a few guys used more than 2 shims. what is the problem with more than 2?

    Change the washers from )()() to )))() and skip the shims - that will bring your slip up quite a bit - search the threads on this.

    Happy riding

    that sequence of washers does'nt look right )))() your only useing 1and a 1/2 of a set of springs, correct me if i'm wrong but i've never seen that configueration.

    i know you put a rebuild kit on but did it come with a new gear wheel?

    Stacking the springs like that adds tension but reduces travel. We dont need all the travel anyway. It wont hurt anything to run them like that.

    my kit was a complete kit: everything from the shaft to the bearings to the washers to the gear.
    i will try this configuration tonight. i dont want to go past 14Nm though, unless it doesnt matter?
