Ryde FX 7041968 GENERAL REBUILD PROCEDURES

WARNING: Before servicing a gas shock it is important that all the gas pressure be discharged from
the unit. Refer to the instructions listed below for the proper procedure of discharging the gas pressure
from a shock. Protective eyewear should be worn to avoid risk of injury while servicing RydeFX gas
charged mono--tube shocks.
Remove the shock from the vehicle. (Account for inner--sleeve in lower shock mount)
Wash the shock body in parts cleaner; then dry with compressed air to remove sand and dirt.
WARNING: When using compressed air to dry components, protective eyewear should be worn to
avoid risk of injury.
Remove inner sleeve and 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.
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.
Remove the small button head screw from the pressure valve, located on top of reservoir.
Using a 9/16 wrench, discharge all gas pressure from the shock by loosening the pressure valve as-
sembly three (3) full turns counter--clockwise.
WARNING: Nitrogen gas is under extreme pressure. Use caution when releasing nitrogen gas from
shock. Protective eyewear should be worn to avoid risk of injury.
CAUTION: Allow all the gas pressure to escape before proceeding with the removal of the pressure
valve assembly. Pressurized gas could eject the valve assembly from the cylinder, resulting in bodily
injury.
Once the shock is completely discharged of gas pressure, remove the pressure valve assembly from
the reservoir cylinder.
With your two thumbs, depress the reservoir end cap 1/2" and remove retaining circlip. Use care not to
scratch the inside of the reservoir.
Reinstall pressure valve assembly partway into the end cap. Using pliers, grasp the end cap by the
pressure valve assembly and extract the end cap slowly from the reservoir by pulling straight out.
Using either an adjustable face spanner or cylinder head socket, fully loosen cylinder head and re-
move rod assembly, placing it on a clean shop towel.
Using the I.F.P (Internal Floating Piston) extraction tool thread the tool into the I.F.P and pull upwards,
removing the I.F.P from the reservoir. Account for wear band and an O--ring.
Pour the oil out of the shock reservoir and main cylinder body into waste container. Discard old oil into
an approved storage container and dispose appropriately. Never reuse damper oil during shock re-
build.
Clean the inside of the shock body using clean parts--cleaning solvent and blow dry using compressed
air.
