subsec-

NOTE: This setting is correct as a pre-
liminary adjustment for most models
and belt types. In some cases, when
starting the engine, the vehicle could
creep, indicating that the belt is too
tight.
If the vehicle creeps, lower the drive
belt height from the preliminary set-
ting. Repeat procedure until creeping
stops.
Reverse Activation
NOTE: The reverse may not activate
or may be harder to activate if the belt
is positioned too high in the driven pul-
ley. If reverse activation does not work
properly, ensure the drive belt is prop-
erly adjusted. Adjust the drive belt
lower in the driven pulley if needed.
Drive Pulley
Drive Pulley Adjustment (only TRA)
The drive pulley is factory calibrated for
sea level operation.
WARNING
Remove the tether cord cap from
engine cut-off switch before per-
forming any adjustment. Vehicle
must be parked in a safe place,
away from the trail.
The drive pulley is factory calibrated to
transmit maximum engine power at a
predefined RPM. Factors such as am-
bient temperature, altitude or surface
condition may vary this critical engine
RPM thus affecting snowmobile effi-
ciency.
This adjustable drive pulley allows set-
ting maximum engine RPM to maintain
maximum power.
