Description
Overview:
This Genuine Husqvarna worm screw (MPN 537079502 / 537 07 95-02) is a small but critical drive component used in Husqvarna professional chainsaws such as the 362 and 365, and in selected brushcutters where specified. Made from hard‐wearing polymer with a precision‐moulded helical form, it transfers rotation from the crankshaft to the chain oil pump, helping maintain consistent bar and chain lubrication. Replacing a worn worm screw restores reliable oil delivery, reduces bar and chain wear, and supports smooth cutting performance. Designed for a precise factory fit, it slots into the existing drive system without modification and works with the original pump and related hardware. Built for daily use, it offers dependable service life for both trade users and DIY owners.
