NOTE : If revalving is to be done, it is imper-
ative that you identify the original shim pack
(size and number of shims). The seal carrier need
not be removed if only revalving is to be done.
Shims can be measured by using a vernier caliper
or a micrometer.
The damper rod is constructed of a plated shaft
design. This damper shaft must be inspected for
any visible wear on the surface of the damper rod.
Another check that must be completed if damper
seal leakage has been noticed, is damper rod
“run-out”. This damper rod must not exceed .025
mm (.001 in).
1. Maximum deflection 0.025 mm (.001 in)
After the new or replacement shim pack has been
selected, reassemble in the reverse order of dis-
assembly. Torque piston nut 11-13 N•m (96-108
lbf•
in ).
1.CAUTION : The damper rod nut can
only be reused 4 times, then, must be re-
placed. Do not substitute this part for non –
O.E.M.
2. This washer (s) used as required to allow ade-
quate threads for damper rod nut.
3. Valve stopper with round edge down.
4. NOTE : Rebound shim stack must not
reach into threads of damper shaft. Wash-
er under damper shaft nut is used to prevent
damper shaft nut from bottoming on threads.
Rebound damping options from Bombardier in-
clude a x-country kit.
Rebound
1. Approximately 0.203 mm (.008 in) clearance
must be allowed between shim stack and stop-
per washer.
2. Whenever tuning for more rebound damping al-
ways use 26 mm (1.02 in) shims against piston
to properly close piston orifice holes. More thin
shims will offer less damping than a few thick
shims of the same overall thickness.
Tuning for less damping it is important to re-
member, never use less than 3
×
26 mm (1.02
in) shims against piston. This will guard against
fatigue breakage.
3. Piston options include 4 pistons, 0, 2, 4, 6, slits
for rebound damping bleeds. These bleed slits
will offer a damping variation to the function of
the shims.
Compression
4. Whenever tuning for more compression damp-
ing always use 30 mm (1.18 in) shims against
piston to properly close piston orifice holes.
Two thin shims will offer less damping than one
thick shims of the equal thickness.
Tuning for less damping it is important to re-
member, never use less than 3 shims against
piston. This will guard against fatigue breakage.
