PRIMARY TRANSMISSION
Primary and secondary clutches
Remove the belt and verify that the sliding half-pulleys of the two
clutches is in good working condition.
To take the belt off, first use the special tool provided to open
the secondary clutch (P/N 529 008 700). Then, slip the belt over
the pulley from rear to front as illustrated. To reinstall the belt,
proceed in the reverse order.
Primary clutch bolt

Recommended torque: 90 - 100 N-m (9–10 kg-m, 70 lbf-ft).
For more information, refer to Chapter 8 - Primary
Transmission System.
Pre-tension of the secondary clutch spring
For more information, refer to Chapter 8 - Primary
Transmission System.
Primary transmission belt
Examine the belt. Make sure it is not cracked, frayed or worn in
an abnormal way (uneven wear, wear on one side only, missing
cogs, or cracked material). Abnormal wear of the belt is often
due to mis-alignment of the pulleys, excessive throttle when the
track is frozen, quick acceleration without a preliminary warm-
up, a scratched or rusted pulley, oil on the belt, or a twisted
replacement belt. If need be, ask an authorized
SNOW
HAWK™ dealer for advice.
Measure the width of the belt. Replace if it is less than 31.6 mm
(1.245 in) wide.
