    The same way as with any other slip test. A dial type torque wrench on the SC nut while holding the gear still with the gear holding tool.

    At least 14nm. You will need the teeth holding tool from seadoo to hold the teeth while you turn the shaft nut. When the teeth gear slips that is your torque or slip. If the pressure washers are brand new try 17nm and allow some breakin time 20 min without running in heavy chop or chopping the throttle from wide open. Oil everything during reassembly. New pressure washers will breakin in a few hours and the slip will need to be readjusted.

    All superchargers, regardless of what clutch washers you use must be torqued to 22 ft lbs.

    Once torqued down my washers usually produce between 11 and 16 newton meters slip depending on the health of all the components of the SC.

    This is the torque wrench i use to measure slip.

    If any portion of your clutch assembly is worn it can cause too much slip.
