Suitable for Partner 350 and 351 chainsaws, integrated drive pulley, with needle bearing clutch and drive pulley assembly -

This product was specifically developed for the Partner 350 and 351 chainsaw series and meets original factory specifications. The integrated drive pulley assembly (with needle bearing drive pulley) is a key component of the centrifugal clutch. It is integrated into the clutch and operates with a built-in mechanism. High-precision needle bearings ensure optimal power transmission. The assembly is connected to the crankshaft or drive shaft. Once the engine reaches its operating speed, the active clutch shoes engage and disengage to ensure smooth and efficient power transmission to the drive sprocket and saw chain. The drive pulley and needle bearing are integrated into this assembly. This replaces original parts that have worn out due to prolonged high loads, bearing damage, or pulley deformation. Problems such as power transmission slippage, chain creep at idle, gearbox noise, and reduced efficiency are effectively resolved. These critical defects restore the machine's powerful and reliable cutting performance.
