Periodic maintenance and adjustment
65
When the rear of the snowmobile is
raised to allow the drive track to spin, a
suitable stand must be used to support
the rear of the snowmobile. Never allow
anyone to hold the rear of the snowmo-
bile off the ground to allow the drive
track to spin. Never allow anyone near a
rotating drive track.
Inspect the drive track condition fre-
quently. Replace any damaged slide
metal. Replace the drive track if it is
damaged to the depth where fabric rein-
forcement material is visible or support
rods are broken. Otherwise, track dam-
age or failure could result in loss of
braking ability and snowmobile control,
which could cause an accident.
Checking the drive track
WARNING
EWS00491
Do not operate the snowmobile if you find
damage to the drive track, or if it has been
maladjusted. Drive track damage or failure
could result in loss of braking ability and
snowmobile control, which could cause
an accident.
Check the drive track alignment and deflec-
tion, and check the track for wear and dam-
age.
Adjust or replace if necessary. (See the fol-
lowing section for more details.)
Checking the drive track alignment
1.
Lift the rear of the snowmobile onto a
suitable stand to raise the drive track off
the ground.
2.
Start the engine and rotate the drive
track one or two turns. Stop the engine.
3.
Check the drive track alignment with the
slide runners. If the alignment is incor-
rect, adjust the drive track.
Measuring the drive track deflection
1.
Lay the snowmobile on its side.
2.
Measure the drive track deflection with a
spring scale. Pull at the center of the
drive track with a force of 100 N (10 kgf,
22 lbf).
TIP
Measure the gap between the slide runner
and the edge of the track window on both
sides.
