Description
Overview:
The Gasket Set for Husqvarna 461 Chainsaw (OEM No. 505 27 84-01) is a genuine Husqvarna replacement kit designed to restore reliable sealing across key engine joints. Made from fuel- and heat-resistant composite materials, the gaskets help maintain compression, correct fuel/air delivery and clean exhaust flow. Suitable for professional and DIY maintenance on petrol chainsaws, it supports dependable performance on models such as the Husqvarna 461 and 455 Rancher. Manufactured to OEM tolerances for an accurate fit, this set is ideal for routine servicing or rebuild work where old, hardened or damaged gaskets risk air, oil or fuel leaks. Correct sealing reduces starting problems, uneven idle and power loss, helping to extend engine life when installed on clean faces and torqued to specification.
