Shock Maintenance (Cont.)
21. Fill the shock body and the reservoir 1/2 full of
Walker Evans 5w shock oil (PN 2874522).
22. Apply a thin film of oil to the IFP O-ring and floating
wear band.
23. Compress the wear band as you install the IFP and
Allow as much air as possible to escape as you
install the piston.
24. Screw the IFP tool onto the floating piston.
IFP TOOL PN PS45908
25. Hold the reservoir as low as possible and slowly
cycle the IFP up and down to purge air out through
the main shock cylinder. Be sure to bottom out the
piston in the reservoir body. Allow time for bubbles to
dissipate and repeat the process until all air is
removed.
26. Set the IFP to the proper depth. Refer to illustrations
for the shock you are working on.
27. Fill the shock body to a level just below the threads
(A).
28. With the cylinder head assembly (B) pushed down
against the valve piston (C), dip the piston assembly
in shock oil.
29. Carefully, insert the piston rod and valve assembly
into the cylinder; slightly oscillating the piston rod to
allow piston to enter shock body bore and purge air.
Slight up and down movement may be required to
allow all air to pass through piston assembly.
30. Slowly push the piston rod and assembly into shock
body until the threads can be engaged.
NOTE: During installation, some shock oil will
overflow. Wrap a shop cloth around shock body to
catch possible oil overflow. Fast installation of the
piston rod and assembly may displace the floating
piston from its original position. This must not occur if
the damper is expected to perform as designed.
31. Tighten the cylinder head on the shock body
securely.
32. Check to be sure IFP is still at the specified depth.
33. Install reservoir end cap and install snap ring.
Charge shock to 200 PSI. Clean shock of oil residue
and check for leaks.
34. Install button screw in reservoir cap.
