3. If the measurement is more than specified, tighten

the adjusting bolts. If the measurement is less than
specified, loosen the adjusting bolts. When the
measurement is within specification range, lock the
adjustment by bottoming the jam nuts against the
axle housings.

NOTE: Vigorously push the underside of the track

up and down. Track must not hit the top of the tunnel
or slap the skid frame.

4. After correct track tension is obtained, check track

a l i g n m e n t ( s e e Tr a c k A l i g n m e n t i n t h i s
sub-section).

NOTE: Track tension and track alignment are

interrelated; always check both even if only one
adjustment seems necessary. Always establish
correct track tension before checking and/or
adjusting alignment.

Track Alignment

NOTE: Proper track alignment is when the rear

idler wheels are equidistant from the inner drive
lugs on the inside surface of the track.

CHECKING

1. Using a shielded safety stand, raise the rear of the

snowmobile off the floor making sure the track is
free to rotate.

! WARNING

The tips of the skis must be positioned against a
wall or similar object for safety. Keep hands, feet,
and clothing away from moving components.

2. Start the engine and accelerate slightly. Use only

enough throttle to rotate the track several
revolutions. SHUT THE ENGINE OFF.

NOTE: Allow the track to coast to a stop. DO NOT

a pply the bra ke bec aus e it could produce
inaccurate alignment conditions.

3. Wh e n the t rack stops rotating, check the

relationship of the rear idler wheels and the inner
track drive lugs. If the distance from the idler
wheels to the inner track drive lugs is the same on
both sides, no adjustment is necessary.

NOTE: If the distance from the idler wheels to the

inner track drive lugs is not the same on both sides,
an adjustment is necessary.

ADJUSTING

1. On the side of the track which has the inner drive

lugs closer to the rear idler wheel, loosen the
adjusting bolt jam nut; then rotate the adjusting bolt
clockwise 1-1 1/2 turns.

2. Continue to check the track alignment and make the

necessary adjustments until proper alignment is
obtained.

3. After proper track alignment is obtained, lock the

adjusting bolt jam nut against the axle housing.

NOTE: Make sure correct track tension is

maintained after adjusting track alignment.

NOTE: Field test the track under actual conditions

and, after the field test, recheck track alignment and
track tension; adjust as necessary.

Overload Springs

To either engage or disengage the spring tension blocks,
use the Spring Block Tool, a spark plug socket, and a
screwdriver and rotate the spring block to the desired
position. Both spring blocks must be in the same
position (either engaged or disengaged).
