Drive track adjustment

WARNING

@ 

A broken track, track fittings or debris thrown by the
drive track could be dangerous to an operator or
bystanders. Observe the following precautions: 

●

Do not allow anyone to stand behind the snow-
mobile 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 snowmo-
bile. Never allow anyone to hold the rear of the
snowmobile off the ground to allow the drive
track to spin. Never allow anyone near a rotating
drive track. 

●

Inspect the drive track condition frequently.
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 failure
could result in loss of braking ability and snow-
mobile control, which could cause an accident. 

@

Drive track deflection measurement

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 kg, 22 lb).

NOTE:

@ 

Measure the gap between the slide runner and the edge
of the track window. Measure both sides. 

@

1 Deflection 
2 100 N (10 kg, 22 lb)

3. If the deflection is incorrect, adjust the drive track.

Standard drive track deflection: 

25–30 mm (0.98–1.18 in) / 100 N (10 kg, 22 lb)
