Description
Overview:
The Clutch Assy for Husqvarna 545 and 550 XP chainsaws is a genuine Husqvarna replacement designed to restore safe, smooth drive engagement. Built from high‐quality steel with robust springing, the three‐shoe centrifugal design copes with high RPM, heat, and the shock loads common in forestry and grounds care. It engages the chain under throttle and disengages at idle to prevent chain creep, supporting accurate cutting and improved safety. This assembly replaces OEM No. 577 51 82-02 and matches factory fit and balance, so it installs cleanly on the crankshaft using the original fixings where applicable. Suitable for the Husqvarna 545 and 550 XP ranges and equivalent Jonsered models, it is a dependable service part for users who want consistent performance from their saw.
Key Features:
- Genuine Husqvarna part for assured compatibility and performance (OEM No. 577 51 82-02)
- Durable, heat‐resistant steel construction for long service life in demanding use
- Three‐shoe centrifugal design for smooth take‐up and reduced chain creep at idle
- Precisely balanced to minimise vibration and bearing wear
- Direct replacement; fits the original crankshaft interface with no modifications
- Helps maintain correct chain brake clearance and sprocket alignment
- Straightforward to fit with basic hand tools, keeping downtime low
- Suitable for professional and DIY users working in forestry, arboriculture, landscaping, and site maintenance
Typical Applications:
Used during routine maintenance or repair when the chain moves at idle, slips under load, or the original clutch shows heat damage or broken springs. Ideal for restoring reliable drive on saws used for felling, limbing, snedding, firewood processing, storm cleanup, and general site clearance. Also appropriate when overhauling powerheads after seizure or heavy use.
