Compatible Husqvarna Chainsaw Models

This two-pack of chain adjuster tensioners fits Husqvarna chainsaws numbered 61, 66, 162, 181, 266, 268, 272, 281 and 288. It is intended for owners of those petrol-powered saws who need to replace a worn or damaged tensioning component.

Replaces OEM Part 501 53 71 01

The adjusters directly replace the original equipment part numbered 501 53 71 01. The upgrade is worth it when the existing tensioner no longer holds the chain at the correct tightness or shows visible wear on the adjustment mechanism.

Simple Bolt-On Installation

Installation requires only basic hand tools to remove the old tensioner and fit the new one in its place. The most common issue is cross-threading the mounting bolts or failing to align the adjuster pin with the guide bar, which prevents proper chain tensioning.
