ATHENA Crankcase Gasket for HUSQVARNA CR 250, WR 250 1999-2011

The ATHENA S410220007004 crankcase gasket is designed for HUSQVARNA CR 250, WR 250 from 1999 to 2011. The crankcase gasket seals between two parts of the crankcase. It is replaced every time they are separated: refitting a crushed gasket means risking an oil leak and, on a two-stroke, an air leak that upsets the carburation.

Fitting tips

1. Clean the gasket faces without scratching or marking them.

4. Tighten in a criss-cross pattern to the manufacturer's torque, then check that the crankshaft turns freely.
