17. Remove the FIST scraper from the bearing assembly
by removing the snap ring. The FIST scraper will fall
out of the bearing.
18. Inspect the bearing assembly for damage. At
m
inimum, the u-cup seal, FIST scraper and all of the
o-rings must be replaced.
NOTE: The bearing assembly DU bushing is not
s
erviceable.
19. Use a scribe or a dental pick to remove the o-ring from
the
inside of the FIST scraper by “spearing” the seal
with the point of the scribe and pulling it out. Use
extreme caution when using a scribe to remove seals.
Always spear the seal with the point of the scribe. Do
not wedge the point of the scribe in behind the seal.
This can scratch the surface of the seal groove which
will compromise the performance and reliability of the
shock absorber.
20. Use the scribe to remove the u-cup seal and o-rings
fro
m the bearing housing. Note the orientation of the
u-cup seal. Be careful not to scratch the seal grooves
or the DU bushing that is pressed into the bearing.
21. To service the o-rings and bypass wear band inside
of the
bypass sleeve, position the shock body with the
external threaded end down. Push the bypass sleeve
down to expose the wire ring. Use a pick to remove
the wire ring.
22. Once the wire ring is removed, flip the shock body
a
round and push the bypass sleeve off of the shock
body.
23. Shown below are the collars, o-rings, and the bypass
we
ar band located underneath the bypass sleeve.
Replace the o-rings and bypass wear band. Inspect
the collars for wear and replace as required.
NOTE: Note the orientation of the external/internal
c
ollars and o-rings.
24. With the shock completely disassembled, inspect all
p
arts for damage, pitting, and corrosion. Replace
piston valve washers that are wavy or pitted.
25. When inspecting piston valve, keep the valve washers
in th
e orientation they are installed in on the shock
shaft.
NOTE: The piston face with the greater number of
r
elief ports is the rebound side and faces the lock nut.
26. Clean all parts with solvent and dry with compressed
air
