Suitable for Husqvarna 455 and 460 chainsaws, including split drive pulley, 7-tooth clutch drum, pinion, main drum and drive wheel chainsaw accessories.

The drive pulley (clutch drum/sprocket) is a crucial component of the chainsaw's power transmission system. It connects the clutch to the guide chain, thus transferring the engine's power to the chain for cutting. Over time, the sprocket teeth wear down, leading to chain slippage and skipping. This impairs cutting performance and accelerates wear on the chain and guide bar. This product is specifically designed for the Husqvarna 455 and 460 chainsaws and features a 7-tooth design. The sprocket is precision-machined from high-quality alloy steel. The specially hardened teeth offer excellent wear resistance and a long service life, ensuring smooth engagement of the chain and sprocket and efficient, stable power transmission. A major advantage is the two-piece design: when the teeth wear, only the sprocket needs to be replaced, not the entire clutch drum. This reduces maintenance costs and increases profitability. The installation dimensions conform to the original specifications; simply replacing worn parts restores normal power transmission. As a high-quality replacement part, this product offers an economical and practical maintenance solution. It is recommended to regularly check the sprocket teeth for wear. Should the tooth tips become blunt, the grooves deepen, or the chain derail unusually, the drive sprocket must be replaced immediately to protect the chain and guide bar and ensure safe and efficient cutting.
