Shocks
12. Clamp the shock in the vice using the body clamp blocks.
If the bearing is still in the body, use the 1 3/8” end wrench
to loosen and un-thread the bearing. If the body cap is what
needs removal, use the large crescent wrench to loosen and
unthread the body cap.
13. Remove the shaft assembly from the body tube, and place
on a clean, lint free paper towel. Remove the shock from
the vice and pour shock oil from body tube into a proper
disposal container. Do not re-use old shock oil.
14. Using the handle of the mallet, push the IFP out of the shock
body on to a folded shop towel.
15. Remove the bleed screw from the IFP using the 1/8" T-
Handle
16. Clean the IFP 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 solvents to evaporate.
17. Set body assembly aside on a clean, lint free towel.
18. Clamp the shaft eyelet securely in vice with the piston end
up.
19. Using a 9/16" wrench, remove the piston lock nut from the
end of the shaft.
20. Hold the tip of the Phillips Head Screwdriver against the
end of shaft. Hold the piston assembly under the top-out
plate and lift upwards. Slide the piston assembly onto the
shaft of the screwdriver. Pull the Screwdriver away from
shock shaft while supporting the piston assembly. Set this
on a clean, lint free towel. There are many pieces to the
piston assembly, and the assembly order of these pieces is
critical to the proper performance of your shock. This step
ensures that the proper order is kept.
21. 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 and set it on a clean, lint
free towel.
22. Remove the bleed screw from the IFP and set them both on
a clean, lint free towel.
FOX PS-5 ASSEMBLY
1.
Using a small pair of snap ring pliers, remove the snap ring
from the bearing housing. Using your fingers, remove the
FIST scraper from the housing. 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.
2.
Use the scribe to remove the u-cup wiper and o-ring seals
from the bearing housing. Be careful not to scratch the seal
grooves or the DU bushing that is pressed into the bearing.
3.
Thoroughly clean the FIST scraper, 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.
4.
Use a scribe or dental pick to remove the o-ring seal from
the IFP.
5.
Install the new, well lubricated, o-ring into the FIST
scraper. Check to make sure the seal is properly seated, and
is 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, 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.
7.
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.
8.
Install FIST bearing into housing. Check for proper
orientation of the FIST bearing. The stepped side of the
FIST bearing should be visible.
9.
Using a small pair of snap-ring pliers, install the snap-ring
into the bearing housing. Check for proper orientation of
the snap ring. The flat side of the snap-ring should be
visible. Check to make sure the snap-ring is properly
seated.
10. Install the new, well greased o-ring onto the IFP.
11. Install the new, well greased o-ring on the IFP bleed screw.
