12. Mount the body cap end of the shock in bench vise.
Slowly fill 3/4 of the body tube with new shock oil.
13. Allow the oil to sit for several minutes to allow air
bu
bbles to escape. Gently tap on the shock body to
assist in removing any trapped air.
14. Install the shock rod/bearing cap assembly into the
sh
ock body. Submerge the piston assembly in the
shock oil.
15. Slowly and carefully pump the piston up and down to
for
ce the oil through the valves stacks and piston
orifices. Gently tap on the shock body to dislodge
trapped air. Continue until air bubbles no longer rise
to the surface of the oil.
NOTE: Pump the valve assembly slowly. Harsh and
a
brupt movements may move the IFP.
16. After removing all of the air
from the shock oil, fill the
shock body with oil. Again, remove any air bubbles
that may have formed.
17. Wrap a clean shop towel around the shock body to
catch oil tha
t overflows. Carefully install the bearing
cap. Tighten the cap securely.
18. Charge the shock with nitrogen to the specified
pressure using the gas
fill tool, PN PS-45259. The
shock rod should be pushed outwards as the IFP
compresses the shock oil.
19. Remove the fill tool from the fill port and reinstall the
bl
eed screw.
20. Test shock by pushing down on the shock rod. The rod
sh
ould extend slowly after pushing it into the tube with
no sound of trapped air inside the oil. If the sound of
air is present or the rate of shock rod compression or
extension dramatically changes, the shock should be
disassembled and the oil replaced.
