WARNING : When using compressed air to dry components, protective eyewear should be worn to
avoid risk of injury.
Place the shock piston rod upper mount in bench vise, begin piston and valve removal. Arrange parts
removed in the sequence of disassembly.
Items to inspect:
Piston rod for straightness, nicks or burrs.
Cylinder Head Assembly / DU Bearing / Seals and Scraper clean, inspect, or replace.
Inside of shock body for scratches, burrs or excessive wear.
Teflon piston and I.F.P wear band for cuts, chipped or nicked edges, or excessive wear.
O--rings for nicks, cuts, or cracks.
Valve discs for kinks or waves.
Hard line and fittings for leaks, kinks, worn of loose threads.
Should any of these items be in question replacement is recommended.
ASSEMBLY :
Place the piston rod upper mount into the vise. Reassemble damper rod assembly in the reverse order
of disassembly. Special attention should be paid to the order of the Rebound and Compression disc
(shim) stacks, ensuring that they are in the same order prior to disassembly. Tighten the lock nut to
15--20 ft--lb of torque.
CAUTION : DO NOT OVER--TORQUE. If excessive torque is applied, damage to the piston and valves
will occur.
Secure the lower mount of the shock in a vise. The use of soft jaws is recommend to prevent damage or
marks to the shock.
CAUTION : It is important that the gas shock be retained in the vise by the lower mount. Any other meth-
od of securing the shock body during these procedures may deform the shock body cylinder.
Apply a thin film of oil onto the floating piston wear band and O--ring and set aside ready for use.
Fill the reservoir to its top with shock oil. Once filled, immediately install floating piston into reservoir
and slowly push straight down to specified depth.
CAUTION : Care must be taken to ensure that air is not trapped between floating piston and top of oil
level. Any air trapped in the oil will cause a lag in the shock absorbers damping ability.
Apply a light film of oil onto reservoir end cap O--ring and then install reservoir end cap and o--ring down
into the reservoir approximately 1/2”. Install retaining circlip making sure it is firmly in place
Tighten down the remaining portion of the pressure valve assembly. With pliers, grasp the end cap by
the pressure valve assembly and pull it up into place against the retainer cir--clip.
Fill the main shock body with shock oil to the bottom of the thread within the cylinder.
With the cylinder head assembly pushed down against the piston, carefully, insert the piston rod and
assembly into the cylinder; Slightly oscillating the piston rod to allow piston to enter shock body bore. A
light coating of oil on the piston wear band will ease installation.
