Chain Brake Band Kit for 445 and 450

This replacement kit suits Husqvarna 445 and 450 petrol chainsaws. It restores the chain brake mechanism using parts that match OEM references 575260403, 537043001, 503890802 and 503855201. The package contains a chain adjuster tensioner, a brake band, a knee joint and a guide bushing for a complete repair.

Verify model and part numbers before ordering

Confirm that your saw is a 445 or 450 model with a two-stroke petrol engine. Cross-check the listed OEM numbers against your service manual or the markings on the worn components. The kit is specific to those models and will not fit other variants or electric units.

Four-piece bundle enables single-service overhaul

Supplying the adjuster, band, knee joint and bushing together lets you replace every wear point in the brake assembly at once. This avoids repeat disassembly and ensures consistent tension and engagement across all mating surfaces.
