Section 06 DRIVE SYSTEM
Subsection 02 (DRIVE PULLEY)
DRIVE PULLEY ADJUSTMENT
The drive pulley is factory calibrated to transmit
maximum engine power at a predefined RPM.
Factors such as ambient temperature, altitude
or surface condition may vary this critical engine
RPM thus affecting snowmobile efficiency.
This adjustable drive pulley allows setting maxi-
mum engine RPM in the vehicle to maintain max-
imum power.
Calibration screws should be adjusted so that ac-
tual maximum engine RPM in vehicle matches the
maximum horsepower RPM given in TECHNICAL
DATA.
NOTE: Use precision digital tachometer for engine
RPM adjustment.
NOTE: The adjustment has an effect on high RPM
only.
To adjust, modify ramp end position by turning cal-
ibration screws.
Calibration screw has a notch on top of its head.

Each number modifies maximum engine RPM by
about 200 RPM.
Lower numbers decrease engine RPM in steps of
200 RPM and higher numbers increase it in steps
of 200 RPM.
Example:
Calibration screw is set at position 3 and is
changed to position 5. So maximum engine RPM
is increased by about 400 RPM.
To Adjust:
Just loosen locking nut enough to pull calibration
screw
partially
out and adjust to desired position.
Do not completely remove the locking nut. Torque
locking nuts to 10 N•m(89lbf•in).
CAUTION: Do not completely remove calibra-
tion screw otherwise its inside washer will fall
off.
CAUTION: Always adjust all 3 calibration
screws and make sure they are all set at the
same number.
