Description
Overview:
This Main Bearing is a Genuine Husqvarna component for supporting the engine crankshaft in high‐revving two‐stroke machinery. Made from high‐quality steel, it keeps the crank running true, reduces friction, and helps maintain oil film and clearances for smooth, reliable operation. It is used across a wide range of Husqvarna/Partner equipment, including the K750 and K760 cut‐off saws, as well as various chainsaws and brushcutters. As a direct replacement for OEM No. 738 22 02 25 (MPN 738220225), it restores correct crank support and reduces wear on associated parts such as seals, cages and raceways. Choosing the genuine bearing helps preserve performance, starting, and service life, and ensures proper fit without modification.
