SPRING REMOVAL

Remove shock absorber from vehicle. Refer to
the appropriate subsection.

Use shock spring remover (P/N 529 035 504) and
put it in a vise. Mount shock in it and turn shock so
that a spring coil rests against spring compressor
jaw.

Close and lock bar. Place handle horizontally by
changing position of clevis pin.

Push down on handle until it locks. Remove
spring stopper and cap then release handle.

SHOCK ABSORBER INSPECTION

Hydraulic Shock

Secure the shock body end in a vise with its rod
upward.

CAUTION: Do not clamp directly on shock
body.

A14F0BA

1. Clamp

Examine each shock for leaks. Extend and com-
press the piston several times over its entire
stroke. Check that it moves smoothly and with
uniform resistance with its rod upward.

After at least 5 complete strokes, pay attention to
the following conditions that will denote a defec-
tive shock:

– A skip or a hang back when reversing stroke at

mid travel.

– Seizing or binding condition except at extreme

end of either stroke.

– Oil leakage.

– A gurgling noise, after completing one full com-

pression and extension stroke.

Renew if any faults are present.

Gas Shock Except Variable Rate

Because of gas pressure, strong resistance is felt
when compressing shock.

For the verification of stroke, or if suspecting an
internal leak between oil chamber and gas cham-
ber, check shock as follows:

Install shock in a vise clamping on its bottom eye-
let with its rod upward. Verify the stroke compres-
sion when the rod is fully extended.

Let it stand for 5 minutes.

Completely push down the shock rod then re-
lease.

The shock should extend unassisted. Rod must
come out at a steady speed. If speed suddenly
increases particularly at end of extension, replace
shock.

Variable Rate Gas Shock

Because of gas pressure, strong resistance is felt
when compressing shock.

For the verification of stroke, or if suspecting an
internal leak between oil chamber and gas cham-
ber, check shock as follows:

Install shock in a vise clamping on its bottom eye-
let with its rod upward. Verify the stroke compres-
sion when the rod is fully extended.

Let it stand for 5 minutes.

Push down the shock rod. The feeling will be stiff
for around first 25 mm (1 in), soft up to 25 to 50
mm (1 to 2 in) and stiff after that. This stiff, soft
and stiff phenomenon shows the normal opera-
tion of shock.

When released, the shock should extend unassist-
ed. The rod speed coming out will go slow - faster
and slow again due to the VR zone.

All Gas Shock

If suspecting a frozen shock proceed as follows:

Place shock in a freezer (temperature below 0°C
(32°F)) for 4 hours.

Push down on rod and note its resistance. If
shock is frozen it will be much more difficult to
compress than for the new one.

DISASSEMBLY AND ASSEMBLY

High Pressure Gas Take Apart Shock (HPG T/A)

There are two types of high pressure gas take
apart (HPG T/A) shock. One type has a tire valve
and the other has a needle valve.

HPG T/A shocks come in two sizes. C-36 shock
is 36 mm (1.417 in) in diameter and C-46 shock is
46 mm (1.811 in).

Release nitrogen (N) pressure on any HPG T/A
shock with internal floating piston (IFP).

WARNING

Nitrogen gas is under extreme pressure. Use
caution when releasing this gas volume. Pro-
tective eye wear should be used.

Mount shock in a vise with HPG shock holding tool
(P/N 529 035 769).

Remove screw on top of valve. Place the needle
guide of gas fill tool kit (needle type) (P/N 503 190

push forward the needle assembly very slowly to-
wards rubber of needle valve. Push on shock tool
valve center rod to release gas pressure.
