Compatible Models

We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.

Compatible equipment / model
  • Husqvarna 445 with original cover 544097902
  • Husqvarna 450 with original cover 544097902
  • Husqvarna 450 Rancher with matching generation and brake design

Product Overview

A cover damaged by a thrown chain, a brake band that will not release, or a missing side assembly can keep an otherwise good saw out of service. This complete clutch-side unit restores bar retention and the hand-guard-operated chain brake when the saw version matches.

The chain brake is a safety system. Do not operate the saw until the band engages and releases correctly, the clutch drum turns freely with the brake off, and all bar hardware is secure.

This is an aftermarket replacement part and is not manufactured or supplied by the original equipment brand.

Compatibility Notice

Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown. Model names alone may not guarantee fitment. Compare the original component, reference number, connector or mounting design, dimensions, and any serial-number or production-date break before purchase.

Frequently Asked Questions

Q: Why will the cover not go back on? A: The brake may be engaged while the cover is off, or the adjuster pin may not be aligned with the bar.

Q: Does it fit a 450 Mark II? A: Only if that saw’s original reference and brake layout match 544097902.

Q: Can I run the saw if the brake feels weak? A: No. Repair and test the safety system before use.
