TRA Drive Pulley Adjustment
The drive pulley is factory calibrated to transmit maximum engine
power at a predefined RPM. Refer to SPECIFICATIONS at the end of
this guide. Factors such as ambient temperature, altitude or surface
condition may vary this critical engine RPM thus affecting snowmo-
bile efficiency.
Summit Models Only
Refer to decal on pulley belt guard to adjust TRA pulley accordingly
to different high altitudes.
All Models
This adjustable drive pulley allows setting maximum engine RPM in
the vehicle to maintain maximum power.
Calibration screws should be adjusted so that actual maximum en-
gine RPM in vehicle matches with the maximum horsepower RPM.
