This is a genuine OEM oil pump worm gear (worm drive) designed to transfer rotational drive from the clutch drum to the oil pump on selected STIHL chainsaws. This critical component ensures a continuous supply of bar and chain oil, reducing friction, minimising wear and extending the service life of the guide bar and chain. Manufactured from high-strength engineered polymer, it provides precise engagement, smooth operation and reliable lubrication performance.
