O.S. Engine 25FX replacement crankshaft overview

This crankshaft is supplied as a direct replacement part for O.S. Engine model OS22602030 and is intended for RC-scale 25FX engine maintenance and rebuilds. The description highlights compatibility with the 25FX designation, the crankshaft's role during servicing, and practical checks to perform during installation.

Fit this crankshaft when carrying out routine teardown and reassembly to restore running condition or when performing incremental tuning. The crankshaft transfers piston motion via the connecting rod and maintains alignment for bearings and seals; during a rebuild, inspect journal faces and bearing seats for wear before reuse.

Installers should verify the engine model marking matches OS22602030 or the 25FX designation and confirm bearing fit and endplay when assembling. If any fitment issues or surface irregularities are evident, address them prior to final assembly to prevent premature wear. This component is an RC accessory for hobby engine maintenance and is not for full-size automotive use.

If your engine is marked OS22602030 or identified as 25FX, this crankshaft is the intended replacement to restore alignment during rebuilds and support workshop tuning efforts.
