24. Slide bearing assembly off of shaft. Use extreme caution
not to scratch inside of the bearing assembly when passing
it over the threads at end of shaft.
FOX™ Shock Rebuild
1. Use a scribe or dental pick to remove the U-cup wiper
(Fig. 8) and O-ring seals (Fig. 9) from the bearing housing.
Be careful not to scratch the seal grooves or the DU
bushing that is pressed into the bearing.
IMPORTANT: 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.
2. Thoroughly clean the bearing housing, and piston assembly
with solvent. Dry with compressed air in a well ventilated
area. If compressed air is not available, dry parts using
clean, lint free paper towels and let sit in a well ventilated
area to allow the remaining solvent to evaporate.
3. Use a scribe or dental pick to remove the O-ring seal from
the IFP.
4. Use a scribe or dental pick to remove the O-ring seals from
the reservoir end cap.
5. Install the new, well lubricated, O-rings into the bearing
housing. Correct placement of the shaft seal O-ring is in the
groove next to the DU bushing. Check to make sure the
seals are properly seated, and are not twisted. If a tool is
required to aid in proper seating of O-ring, use the non-
writing end of a pen, or a similar soft, blunt object, to push
it in.
6. Install the new U-cup seal into bearing. U-cup should be
installed so the cupped end is facing the DU bushing inside
of bearing. Check to make sure seal is properly seated. If a
tool is required to aid in proper seating of U-cup seal, use
the non-writing end of a pen, or a similar soft, blunt object,
to push it in (Fig. 10).
