Description
Overview:
This Genuine Husqvarna crankshaft oil seal (part no. 503 26 02 05) is designed to restore a reliable seal around the crankshaft on high‐performance Husqvarna cutters and chainsaws, including the 3120K Disc Cutter and 281 Chainsaw. It is made from a tough, oil- and fuel-resistant elastomer with metal reinforcement and a spring-loaded sealing lip for steady contact on the shaft. The seal prevents oil leakage and helps keep out dust and debris, supporting stable crankcase pressure on two-stroke engines. The result is smoother running and consistent performance under heavy use. Built for demanding conditions, it is suitable for professional and DIY maintenance and fits a wide range of Husqvarna models used on site, in the workshop, and in forestry work.
