Description
Overview:
This rear isolator spring is a replacement coil spring designed for the vibration control system on Husqvarna petrol chainsaws. Made from resilient spring steel with formed ends for secure seating, it works between the chassis and rear handle to limit vibration transfer from the engine and cutting gear. The result is steadier handling and better comfort over longer cutting sessions. Identified by part number 545 06 31-01 (545063101), it is made to match the original fit and function on the Husqvarna 236 and closely related models such as the 120 Mark II. Use it to replace a worn, stretched, or broken spring and bring the saw's vibration damping back to its intended level without altering the tool's balance or control.
Key Features:
- Direct-fit replacement referenced by MPN 545 06 31-01 for confident identification
- Durable spring steel construction for strength, resilience, and long service life
- Helps reduce vibration reaching the rear handle for improved comfort and control
- Consistent spring rate supports accurate throttle control and cut precision
- Sized to factory geometry for correct alignment and reliable seating
- Straightforward fitting with basic hand tools; no modification expected
- Ideal preventive replacement when overhauling the handle or engine cradle area
- Suitable across several Husqvarna 200-series models to simplify parts stocking
Typical Applications:
Replace during routine servicing or when excessive handle vibration, rattling, or poor control is noticed. Common when refurbishing used saws, after impacts, or when other isolation parts have perished. Suitable for domestic firewood cutting, garden maintenance, light arborist tasks, and site clearance where steady handling is important.
