Mount the shock on vise. Remove screw on top
of valve. Place the needle guide of gas refill tool
on the shock valve. While depressing the detent
pin of the gas refill tool and pushing forward the
needle assembly, insert the needle through the
rubber core of the pressure valve assembly of the
shock.

NOTE: For replacement of the needle or filling the
shock, carefully follow the instructions provided
with the gas refill needle type tool kit (P/N
5 03 190
102).
On some models, rubber may pop out of needle
valve when inserting tool needle. If so, remove
valve core and rubber then, reinstall rubber with
its larger diameter last.

When the shock is filled with gas, install back the
screw on top of the valve.
All Shock Types
NOTE: Carefully inspect damper for gas or oil
leaks. Any leaks must be corrected before con-
tinuing.
Damper gas pressure cannot be confirmed by
using a pressure gauge. The volume of gas in the
shock is very small, and the amount lost during
gauge installation will lower the pressure too
much and require refilling.
After recharging is complete the rebuilt shock
should be bench-tested.
Stroke the shock to
ensure full travel and smooth compression and
rebound action. If the shaft moves in or out er-
ratically this could indicate too much air is trapped
inside. If the shaft will not move or has partial
travel then it may be hydraulically locked. In ei-
ther event the shock must be rebuilt again. Pay
particular attention to the placement of the IFP,
quantity of oil and shim stack/piston assembly.
