Description
Overview:
The Insulation Wall for Husqvarna 340 and 353 chainsaws is a Genuine Husqvarna OEM part designed to reduce heat transfer inside the saw body. Moulded from a heat‐resistant black polymer, it forms a reliable thermal barrier between the cylinder/exhaust side and the intake area, helping to protect the carburettor, air filter housing and nearby plastics from heat soak. By limiting temperature rise, it supports smooth running, easier hot restarts and longer service life of adjoining components. This replacement panel is produced to factory dimensions for a precise fit on the specified saws and reuses the original fixings for a tidy install. Supplied under MPN 537 42 28‐01 (equivalent to 537422801), it is a practical service item for keeping your Husqvarna in good order.
