Ski Alignment - Arctic Cat 500 Sno Pro Operator's/Performance Manual

5. When proper track deflection is attained, loosen
the right-side rear axle nut just enough to apply
blue Loctite #243 to the axle threads; then tighten
the nut to 40-45 ft-lb.
CAUTION
Make certain the right-side rear axle nut is tightened
or component damage will occur.
6. Start the engine and accelerate slightly. Use only
enough throttle to turn the track several revolu-
tions. Shut engine off.
! WARNING
DO NOT stand behind the snowmobile or near the
rotating track. NEVER run the track at high speed
when the track is suspended.
NOTE: Allow the track to coast to a stop. Do not
apply the brake because it could produce an inac-
curate alignment condition.
7. When the track stops rotating, check the relation-
ship of the rear idler wheels and the inner track
drive lugs. If the rear idler wheels are centered
between the inner track drive lugs, no adjustment
is necessary.
8. If the idler wheels are not centered between the
inner track drive lugs, adjust track alignment.
! WARNING
Make sure the ignition switch is in the OFF position
and the track is not rotating before checking or adjust-
ing the track alignment.
9. Loosen the right-side rear axle nut; then on the
side of the track which has the inner track drive
lugs closer to the rear idler wheel, rotate the
adjusting bolt clockwise 1-1 1/2 turns.
10. Check track alignment and make necessary adjust-
ments until proper alignment is obtained.
NOTE: Make sure correct track tension is main-
tained after adjusting track alignment.
11. Loosen the right-side rear axle nut just enough to
apply blue Loctite #243 to the axle threads; then
tighten the nut to 40-45 ft-lb.
If the axle nut is not tightened, the adjusting bolts
could loosen causing the track to ratchet, derail, or
lock.

SKI ALIGNMENT

Checking
NOTE: Track tension and alignment must be
properly adjusted prior to checking or adjusting
ski alignment. Ski alignment must be performed on
a flat, level surface. Ski toe-out must fall within the
specified range.
1. Raise the front end of snowmobile just high
enough that the ski shocks are fully extended but
the skis are still resting on the floor.
2. Using Bellcrank Centering Tool (p/n 0644-541),
position the slots of the tool onto each bellcrank
and allow the tool to lie flat on the drag link cap
screws.
NOTE: If the centering tool is not available, steer-
ing can be centered in the chassis by taking mea-
surements from each side of the drag link to a
location on the chassis which would be of equal
distance from each side of the drag link.
Always remove the centering tool after the steering
has been properly aligned.

3. Using a very light hold-down strap (bungee cord)
between the ski handles, apply a very light load
approximately 2-4 lb pulling the skis together just
enough to pull the slack.
NOTE: Track tension and alignment must be
properly adjusted prior to placing the straightedge
against the outside edge of the track.
