GENERAL
Some drive pulley components (return spring, cal-

only be performed by experience me-
chanics since they can greatly affect vehicle
performance.
WARNING : Any drive pulley repairs
must be performed by an authorized
Bombardier snowmobile dealer, or other such
qualified person. Sub-component installation
and assembly tolerances require strict adher-
ence to procedures detailed.
