Sold under O.S. Engine model OS44502000, this crankshaft is intended for use in FS-200S-labelled RC glow engines. The description concentrates on correct fitment, workshop checks, and the part's role during engine servicing rather than promising performance gains.

Fitment reminder: the listing specifies FS-200S as the compatible engine family; always check the engine's identification stamp before ordering to ensure the correct component. This is an RC glow engine part and should be handled with appropriate workshop precautions.

If press-fit techniques or bearing removal are unfamiliar, consult a specialist.
