Husqvarna K750 and K760 genuine OEM ball bearing style clutch drum pulley.
IMPORTANT NOTE: In order to decrease the engine running temperature, a cooling fan is now integrated with the clutch drum. The clutch drum is not backwards compatible without a small re-work of the crankcase:
- The fin that has been used for guiding the belt needs to be removed
- Use a pair of pliers or a monkey wrench and break the fin along the dashed red line
