Drive track
WARNING
EWS00480
A broken track, track fittings or debris
thrown by the drive track could be danger-
ous to an operator or bystanders. Observe
the following precautions:
●
Do not allow anyone to stand behind the
snowmobile when the engine is running.
●
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 damaged slide metal.
Replace the drive track if it is damaged
to the depth where fabric reinforcement
material is visible or support rods are
broken. Otherwise, track damage or fail-
ure could result in loss of braking ability
and snowmobile control, which could
cause an accident.
Checking the drive track
WARNING
EWS00490
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 deflection, and check
the track for wear and damage.
Adjust or replace if necessary. (See the fol-
lowing section for more details.)
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. Measure
both sides.
