Description
Overview:
This Genuine Husqvarna Pawl (No. 501 45 41 01, MPN 501454101) is a small but critical engagement component used across many Husqvarna chainsaws and pole saws. Made from durable steel and built to Husqvarna's OEM specification, it provides one‐way engagement within the starter or related ratchet mechanism, driving in one direction and releasing on the return stroke. This action prevents reverse movement and helps deliver smooth, consistent operation. A precise fit is essential for reliable starting and controlled running, and this genuine part restores the intended interaction with the mating ratchet or flywheel. Suitable for a wide range of models, including the Husqvarna 2163 and 2171, it is a dependable choice for routine service or to replace a worn or damaged pawl.
Key Features:
- Genuine Husqvarna OEM part for accurate fit and performance
- Steel construction for strength and resistance to wear in demanding use
- Precision profile engages cleanly with matching ratchet/flywheel components
- Helps prevent back‐drive and slippage for consistent starting and control
- Stable under vibration and repeated cycling in professional and DIY environments
- Typically straightforward to install with standard tools and the correct service guidance
- Direct replacement for Husqvarna 501 45 41‐01 / 501454101
Typical Applications:
Used during servicing of recoil starter and ratchet systems on Husqvarna chainsaws and pole saw attachments. Ideal for resolving slipping or non‐engaging starters, chipped or worn pawls, and preventative maintenance when overhauling the starter, flywheel, or clutch area.
Also known as:
Ratchet catch, anti‐reverse latch, drive dog, flywheel dog, locking catch, one‐way latch.
