WARNING
Never use any type of impact wrench at drive
pulley removal and installation. The use of
impact wrench could damage the drive pulley
and modify the calibration.
Some drive pulley components (return spring,
ramp) can be changed to improve vehicle perfor-
mance in high altitude regions. A service bulletin
will give information about calibration according
to altitude.
CAUTION: Such modifications should only be
performed by experienced mechanics since
they can greatly affect vehicle performance.
Verify spring specifications before installation.
Do not only refer to the spring color code.
NOTE: TRA drive pulley stands for Total Range
Adjustable drive pulley.
