2-72 PERIODIC MAINTENANCE
Periodic Maintenance Procedures
Purge the air from between the gas reservoir [A] and rear
shock body [B] by slowly pumping the piston rod [C] in
Add the specified oil up to the damping adjuster assembly
hole neck [A].
Hold the adjuster assembly hole facing up and turn the
shock absorber to bleed the air from the reservoir com-
Fully extend the piston rod assembly.
Inject the nitrogen gas to a pressure of 50 kPa (0.5
kgf/cm², 7 psi) through the valve on the gas reservoir.
Check the rear shock body and gas reservoir for oil and
If there are leaks, reassemble the related parts.
Replace the O-rings [A] with new ones and apply shock
Install the gas reservoir damping adjuster assembly [B]
Torque - Gas Reservoir Damping Adjuster Assembly: 29.5
N·m (3.01 kgf·m, 21.8 ft·lb)
Wipe off all oil from the shock absorber body and piston
Inject the nitrogen gas up to the 980 kPa (10.0 kgf/cm²,
142 psi) pressure.
High pressure gas is dangerous and can explode,
causing serious injury. To avoid injury, have a qual-
ified mechanic pressurize the shock reservoir with
nitrogen gas only. Do not use air or other gases,
since they may cause premature wear, rust, fire haz-
ard or substandard performance.
Install the spring (see Rear Shock Absorber Spring Re-
Install the rear shock absorber (see Rear Shock Absorber
Installation in the Suspension chapter).
Adjust the spring preload (see Spring Preload Adjustment
in the Suspension chapter).
Install the removed parts (see appropriate chapters).
