NOTE: If revalving is to be done, it is imperative
that you identify the original shim pack (size and
number of shims). The seal carrier need not be
removed if only revalving is to be done.
Shims can be measured by using a vernier caliper
or a micrometer.
NOTE: All shims should be carefully inspected and
any bent or broken shims must be replaced for the
shock to function properly.
After the new or replacement shim pack has
been selected, reassemble in the reverse order
of disassembly. Torque piston nut to 27 - 29 N•m
(20 - 21 lbf•ft).

CAUTION: The damper rod nut can only be
reused 4 times, then, must be replaced. Do
not substitute this part for non - O.E.M. use
Loctite 271 on nut each time.
This (these) spacer washer(s) must be used as
shown to ensure damper rod nut does not bottom
out or contact shaft threads.
Rebound valve stopper with round edge facing
nut.
NOTE: Rebound shim stack must not reach into
threads of damper shaft. Spacer under damper
shaft nut is used to prevent damper shaft nut from
bottoming on threads.

If the seal carrier assembly is replaced, use seal
pilot to guide seal over damper shaft. Lubricate
seal carrier guide pilot before use.
CAUTION: Failure to use seal pilot will result in
seal damage.
Reassemble damper rod assembly, taking care to
properly assemble shim packs as required for your
dampening needs. Ensure that the shaft piston
is installed with the slits/larger intake holes facing
the rebound shim stack.
