SECTION 03 - CHASSIS PREPARATION
MMC2005-001_03A.FM

After recharging is complete and before installing
the spring 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 erratically this could indicate too
much air is trapped inside. If the shaft will not
move or has partial travel then it may be hydrauli-
cally locked. In either event the shock must be re-
built again. Pay particular attention to the placement
of the IFP, quantity of oil and shim stack/piston as-
sembly.
1. Automotive type air pressure hose
2. 2 stage regulator, delivery pressure range 2070 kPa (300 PSI)
3. High pressure cylinder filled with industrial grade nitrogen
4. Valve tip (P/N 529 035 570)
Reinstall damper spring retainer, then your spring.
Next, thread the spring pre-load rings up to the
spring. Set pre-load according to recommended
spring length specifications. Your damper is now
ready for reinstallation to your snowmobile.
CHASSIS SET-UP
General
Reducing rolling resistance of a snowmobile is
also an important area to explore when you are
searching for the ultimate top speed. The horse-
power required to overcome rolling resistance or
drag increases approximately with the square of
velocity so small reductions here can provide mea-
surable improvements in top speed.
Good chassis set up starts with accurate align-
ment of the drive axle, countershaft, suspension
system, and chassis. Use the following procedure
to check your vehicle:
Remove the rear suspension, driven clutch, tuned
pipe and muffler, track and drive axle. Check to see
that the spacing of the drive sprockets is correct
on the drive axle. The sprockets should be cen-
tered in the space between the rows of internal
drive lugs on the track.
Use a press or special tool (P/N 861 725 700) for
shifting the sprockets. The sprocket indexing
should also be checked. The maximum desyn-
chronization is 1/16 inch (1.5 mm). The drive axle
can be chucked in a lathe and spun to observe the
sprocket “wobble” and run out. Wobble should
not exceed 2 mm (.080 in). While this amount of
wobble may look excessive, it does not affect per-
formance. If wobble is more than allowed, the
sprockets should be replaced.
Maximum run out should not exceed 0.5 mm
(.020 in). A maximum of 1 mm (.040 in) can be re-
moved from the sprockets to true the diameter.
CAUTION:
Do not remove more than 1 mm
(.040 in) of material or the sprockets will start
to go out of pitch with the track.
TYPICAL
Now, reinstall the drive shaft. Using a large carpen-
ters square, check to see that the drive axle is
square (90°) with the tunnel. If not, slot the left end
bearing housing holes and reshim the chaincase
to square up the drive axle and the countershaft.
