Applicable to the passive split sprocket FUSCWA HUSQVARNA HUS61-66-266-268-272--DTEKGAZ

Specifically designed for Husqvarna Classic and Professional chainsaw models 61, 66, 266, 268, and 272. Construction: Separate sprocket and drive pulley assembly. This product is the main component of the clutch transmission. The two-piece design separates the drive pulley from the sprocket. It replaces defective original parts affected by wear, deformation, gear breakage, bearing damage, or oil leaks resulting from continuous operation under heavy load. It precisely restores transmission efficiency and resolves issues such as uneven chain running, clutch overheating, and power loss.
