Mtanlo Spur Sprocket Clutch Drum Assembly

This kit is designed for specific Husqvarna, Jonsered, and Partner models. Before purchasing, verify that your chainsaw requires a 6-tooth sprocket with a 0.375-inch chain pitch to ensure a proper fit.

You should consider a replacement if you notice excessive wear on the sprocket teeth, deep grooves in the clutch drum, or if your chain is slipping and failing to engage properly during operation.

It is engineered as a direct fit, meaning it replaces the original part without modifications. While installation is straightforward, you will typically need a clutch removal tool or a piston stop to safely remove the existing clutch assembly.

This kit focuses on the clutch drum and spur sprocket assembly. It is generally recommended to inspect your existing needle bearing for wear and replace it if necessary, as it is not always included in this specific kit.

The 6-tooth count and 0.375-inch pitch must match your chainsaw's drive system exactly. Using a mismatched sprocket will cause the chain to bind, wear prematurely, or fail to drive the chain at the correct speed.
