SHIM PART NUMBERS

Shims are used in a stack on the top and on the bottom of the
shock piston. The stacks can be adjusted to control the amount
of fluid that is forced by as the piston travels through its motion.
Below is a chart that has the part numbers of these shims,
proceeding the part number is the size of the washer (out side
diameter x thickness). A thick washer (.700 x .010) will try to
keep the fluid from passing through the piston as it travels.

Refer to the appropriate parts manual for a complete listing of
shock parts.

Shim Arrangement

Shown below is an example of how valving stacks are arranged.
Parts in the box below are an example of standard valving.

NOTE: Note the direction of the valve piston before
disassembly. The side with the greater number of
relief slots (1) should face the nut end (2) of the
shaft.
