8. Internal Floating Piston Shocks, using a slotted
screwdriver, loosen the pressure valve assembly
.
counter-clockwise two full revolutions allowing the
gas pressure to fully escape past the pressure valve
assembly O-ring.
9. Emulsion Shocks: With the shock inverted and the
piston rod fully extended, secure the lower mount of
the shock in a vise. Allow a couple of minutes for the
gas pressure to separate from the oil and rise to the
top. Using a rag as a shield to prevent spraying gas
and oil; place rag over top the pressure valve
assembly and slowly loosen the valve assembly with
slotted screw driver three full revolutions, allowing all
the gas pressure to escape past the pressure valve
assembly O-ring.

shock body. Account for wear band and an O-ring.
Note: Not applicable for emulsion shock
15. Clean the inside of the shock body using clean parts-
cleaning solvent and blow dry using compressed air.
16. Place the shock piston rod upper mount in bench vise,
begin piston and valve removal. Arrange parts
removed in the sequence of disassembly. The piston
should have the flat slots facing the nut end (as
highlighted in black).
17. Items to inspect: Piston rod for straightness, nicks or
burrs. Cylinder Head Assembly / DU Bearing clean,
inspect, or replace. Inside of shock body for
