Maintenance

Track Alignment

Check track alignment at the intervals outlined in the periodic mainte-
nance chart beginning on page 50. Make sure the track is centered and
running evenly on the slide rails. Misalignment will cause excessive
wear to the track and slide rail.

1. Support the rear of the

snowmobile slightly off the
ground with an appropriate
snowmobile support.

2. Start the engine and apply a

small amount of throttle
until the track turns slowly
at least five complete revo-
lutions. Stop the engine.

3. Inspect track alignment by

looking through the track
windows to make sure the
rails are evenly spaced on
each side. If the track runs
to the left, loosen the left
idler wheel mounting bolt and tighten the left track adjusting bolt. If
the track runs to the right, loosen the right idler wheel mounting bolt
and tighten the right track adjusting bolt.

4. After adjustments are complete, tighten the locknuts and idler shaft

bolts. Torque to 35-40 ft. lbs. (47-54 Nm).

5. Repeat step 2 to verify proper alignment.

WARNING

When performing the following checks and adjustments, stay clear of all mov-
ing parts to avoid serious personal injury. Make sure the track contains no
objects that could be thrown out while the track is rotating. Keep clear of track.
This includes but is not limited to hands, tools, feet and clothing. Make sure no
one is standing close to the machine while the track is rotating.

Maintenance

Track Warm Up

After storing your snowmobile
outside overnight, warm up the
track before driving the snow-
mobile. This reduces drive
clutch wear.

1. Support the rear of the

snowmobile slightly off the
ground with an appropriate
snowmobile support.

2. Start the engine.

3. Abruptly engage the clutch, allowing the track to turn for several

revolutions.

4. Release the throttle and apply the brakes.

5. Stop the engine.

6. Lower the rear of the snowmobile to the ground while the engine is

off.

WARNING

Never hold the snowmobile up or
stand behind it while rotating the
track. A loose track or flying debris
could cause serious personal injury
or death.

Track Inspection

Check track condition at the intervals outlined in the periodic mainte-
nance chart beginning on page 50.

1. Support the rear of the

snowmobile slightly off the
ground with an appropriate
snowmobile support.

2. Rotate the track by hand to

check for wear or damage.

3. Carefully examine the

track along the entire
length of each track rod,
bending the track and
inspecting for breakage.

TIP: The three most common

places where breakage
occurs are shown in the illus-
tration.

4. Check the track clips and

tighten any loose clips. If
any rod damage is found, install a new track.

TIP: This snowmobile track has molded-in track clips. It is common for a thin

layer of rubber to detach from the clip area and peel off during initial use.

WARNING

Inspecting the track while the engine
is running can result in serious per-
sonal injury if the track should being
to move. Never inspect the track with
the engine running. Never hold the
snowmobile up or stand behind it
while rotating the track. A loose track
or flying debris could cause serious
personal injury or death.

Slider Replacement

POLARIS rail slides have a wear
limit indicator groove to indicate
the minimum permissible slide
thickness. Replace the rail slides if
they are worn to the top of the
groove at any point along their
length. Failure to do so may result
in permanent damage to the track
or rails.

Track Lubrication

Track failure, loss of vehicle control and braking ability can result from
extended use of this vehicle on surfaces providing marginal lubrication
between the slider and track guide clips. Examples of marginal lubrica-
tion would include lakes without snow cover, icy trails and no-snow
conditions.

The slide rail is designed to operate in conditions with adequate snow
cover in order to provide sufficient lubrication. Excessive wear indicates
insufficient lubrication. A new slider can cause faster heat build up in
limited lubrication than a used slider, resulting in excessive wear.

TIP: Track damage or failure caused by operation on ice or poor lubrication con-

ditions may void the track warranty.

Steering System

The steering systems on POLARIS snowmobiles can be adjusted with
ski toe alignment. Improper toe alignment can cause erratic steering.
See your dealer for adjustments.

WARNING

Improper alignment or adjustment may cause loss of steering control, result-
ing in serious injury or death. Do not attempt to change the ski alignment. See
your POLARIS dealer.
