WARNING
REMOVE EACH COMPONENT AS SHOWN IN THE
EXPLODED VIEW ON THE PREVIOUS PAGE.
Recommended checks
• Check if the centrifugal weights have been damaged.
• Check if there are any signs of wear on the housing (see image).
• Check if there are any signs of wear on the housing friction bushing
(see image).
• Check if there are any signs of wear on the pulley (due to the friction
of the transmission belt).
• Check the free wheel or the idle speed bearing.
Replacement conditions
• Housing (12):
Change whenever the wear marks displayed in the image exceed the
wear limit. The allowable wear limit of the housing is less than 14 mm.
• Friction bushing (15):
Replace the cover bushings whenever there is too much noise at
idling speed between these and the sliding tower of the pulley. Use a
gauge to measure wear as shown.
The maximum space of wear allowed is: 1 mm
WARNING
ALWAYS CHANGE THE THREE RINGS (15) AT THE
SAME TIME.
• Floating bearing (3):
Change when you manually detect irregular rotation or you hear a
squeaking noise as the bearing rotates.

TO MAINTAIN THE
PERFORMANCE OF THE
PULLEY, BE SURE TO CLEAN
THE BUSHINGS OF THE
PULLEY WITH A MICROFIBRE
TOWEL OR A DRY CLOTH.
