Description
Overview:
The Knee Joint Assembly is a genuine Husqvarna replacement part used in the braking mechanism of professional chainsaws such as the 562 XP and 545. It is a compact, precision-formed metal linkage that transfers motion from the front hand guard to the brake system, helping the saw stop the chain quickly and reliably. Built from durable metal for long service life, it is made to original factory tolerances for a precise fit and smooth movement. This part is essential when the original joint becomes bent, worn, sticky, or damaged by debris or impacts. Replacing a faulty joint helps restore safe operation and consistent braking performance across a range of compatible Husqvarna models used in forestry, arborist, and grounds maintenance work.
Key Features:
- Genuine Husqvarna part for assured compatibility and performance.
- Robust metal construction for strength and wear resistance in demanding use.
- Manufactured to OEM tolerances for a snug fit and smooth pivoting action.
- Helps restore fast, reliable brake engagement and release.
- Direct replacement for worn, bent, or seized joints; no modifications required.
- Suitable for high-vibration environments common to professional chainsaw use.
- Supports routine servicing to maintain safety compliance.
- Clearly identifiable by MPN 505199301 for easy parts matching.
Typical Applications:
Used during chain brake servicing and repairs after heavy use, impacts, or contamination. Common in workshop overhauls, fleet maintenance, and refurbishing saws to maintain safe stopping performance. Suitable for forestry, arboriculture, landscaping, and grounds care teams who require reliable braking action on their Husqvarna chainsaws.
