CHECKING
! 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.
1. Remove excess ice and snow buildup from the track,
track drive sprockets, and the inside of the skid
frame.
2. Elevate the snowmobile on a shielded safety stand
high enough to use a spring scale.
3. At mid-point of the track (on the bottom side), hook
a spring scale around a track clip; then pull down on
the scale to the recommended pressure. Measure the
deflection (distance) between the bottom of the wear
strip and the inside surface of the track clip. Com-
pare the measurement with the chart in the General
Information section.
NOTE: Measurement is from the bottom of the

wear strip at the point of the shock pad on the slide
rail.

perform all adjustments on both sides of the snowmo-
bile.
