RYDE FX MONO-TUBE SHOCK
DISASSEMBLY
Procedures for the proper disassembly and assembly of
Ryde FX gas charged IFP and emulsion mono-tube shock
absorbers.
1. Remove the shock(s) from the vehicle.
2. Before unscrewing pre-load springs, measure the
compressed length of the installed spring and mark position
for reinstallation.
3. If the shock incorporates a spring, remove the spring and
all collateral retainers.
4. Wash the shock body in parts cleaner; then dry with
compressed air to remove sand and dirt.
5. Remove bearing, sleeve and/or bushings from lower shock
mount eyelet. 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.
6. Remove the small button head screw from the pressure
valve assembly.
7. Depressurize the shock.
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.
10. Allow all the gas pressure to escape before proceeding with
the removal of the pressure valve assembly. Pressurized gas
and shock oil could eject the valve assembly from the
cylinder resulting in bodily injury.
11. Using a slotted screwdriver, remove the pressure valve
assembly from the lower end mount. Account for an O-ring.
12. Using an adjustable face spanner (PN PS45262), fully
loosen and remove cylinder head assembly.
13. Pour the oil out of the shock body. Discard old oil into an
approved storage container and dispose appropriately.
Never reuse damper oil during shock rebuild.
14. Using the I.F.P extraction tool thread the tool into the I.F.P
and pull upwards, removing the I.F.P from the 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 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. Cap and rod seals for nicks, cuts or
cracks. Valve discs for kinks or waves. Compression
bumpers (ski shocks only) for chipping, cracking or
missing. Should any of these items be in question
replacement is recommended.
