Drive Chain
The drive chain should be lubricated
every 10 operating hours with Arctic Cat
Synthetic Chain Lube (p/n 5639-038) or
with a suitable dry, graphite-based chain
lubricant. By using the recommended
chain lube or a dry, graphite-based chain
lubricant, dirt buildup on the drive chain
will be minimized. Before each lubrica-
tion, inspect the drive chain for dirt accu-
mulation.
To lubricate the drive chain, shut the
engine off and wait for all moving parts
to stop, remove the drive chain shield,
and lubricate the drive chain. After lubri-
cating the drive chain, install the drive
chain shield.

NOTE: If the recommended chain
lube or a dry, graphite-based chain
lubricant is not available, lubricate
the drive chain with several drops of
petroleum-based oil. If the snowmo-
bile is operated in the summer with
the optional wheel kit, the drive chain
should be lubricated more frequently.
Drive Chain Tensioner
The drive chain tensioner is automatic;
therefore, no adjustment is required by
the snowmobile owner. The tensioner
and chain should be checked annually for
proper operation and excessive wear and
replaced when necessary. Check the ten-
sioner by pushing down on it and releas-
ing it. It should immediately spring back
and put tension on the drive chain.
Rear Suspension
This procedure should be done every 20
operating hours.
1. Shut engine off and wait for all mov-
ing parts to stop.
2. With the gas tank nearly empty (less
than 1/4 full), lay the snowmobile on
its side. A piece of cardboard should
be used to protect the finish on the
hood and belly pan.
3. Remove ice and snow buildup from
the skid frame to expose the two
grease fittings.
4. Lubricate the grease fittings with an
all-temperature grease.
Track Tension

NOTE: Track tension and track
alignment are interrelated; there-
fore, always check both, even if only
one adjustment seems necessary.
Track tension is directly related to the over-
all performance of the snowmobile. If the
track is too loose, it may slap against the
tunnel causing wear, or it may ratchet on the
track drive sprockets. Arctic Cat recom-
mends that the track tension be checked
once a month and adjusted accordingly.
Checking Track Tension
1. Remove excess ice and snow
buildup from the track, track drive
sprockets, and the inside of the skid
frame.
2. Place the rear of the snowmobile up
on a safety stand high enough so the
track is free of the floor.
3. Without exerting any pressure on the
track, measure the distance between
the bottom of the wear strip and the
inside surface of the track. The mea-
surement must be within specifica-
tions of 6.4-9.5 mm (1/4-3/8 in.). If
the measurement is not within speci-
fications, an adjustment is necessary.

! WARNING
Track tension must be properly main-
tained. Personal injury could result if
a track is allowed to become exces-
sively loose.
! WARNING
DO NOT attempt to check or adjust
track tension with engine running.
Turn ignition key to the OFF position.
Personal injury could result from
contact with a rotating track.
