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.
Track Tension

NOTE: Track tension and track
alignment are interrelated; therefore,
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.

Adjusting Track Tension

2. Loosen the rear idler wheel adjust-
ing bolt jam nuts.

! 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 con-
tact with a rotating track.
