Description
Overview:
This Worm Wheel is a genuine Husqvarna spare for petrol chainsaw engines, engineered to transmit drive reliably within the powerhead. Precision-moulded from a durable, oil- and heat‐resistant polymer, it provides smooth, low-friction rotation and long service life under typical cutting conditions. Used to drive ancillary systems (commonly the bar and chain lubrication pump), it helps keep the saw running efficiently by maintaining consistent power transfer. Designed for Husqvarna 545 Mark II and 545G Mark II engines, it offers a direct fit with correct clearances and tooth profile for dependable engagement. As a Genuine Husqvarna part (582 81 40 01), it is built to the manufacturer's specification and supports proper maintenance schedules, helping to prevent premature wear of neighbouring components.
