O.S. Engine OS44502000 Crankshaft FS-200S  [OS44502000]

Crankshaft for FS-200S engines

This crankshaft is supplied under the O.S. Engine model number OS44502000 and serves as the replacement crankshaft for FS-200S-designated RC glow engines. The description here focuses on fitment, workshop considerations, and the part's role in engine service rather than performance claims.

Fitment note: the product name identifies FS-200S as the intended engine family; confirm the engine model stamp before ordering to ensure correct match. This crankshaft is an RC-scale engine part intended for model glow engines and should be handled with standard small-engine workshop practices.

Installation and service guidance: inspect connecting rod clearance and main bearing seats during replacement, use correct torque values for retaining hardware as provided by your engine manual, and verify free rotation before reassembly into the model. If unsure about press-fit operations or bearing removal, consult a trained technician or a dedicated engine service guide.

Tuning and maintenance role: the crankshaft is a core rotating component that affects balance and mechanical timing in model engines; during routine maintenance it is a common spare item to inspect for wear, to confirm bearing condition, and to replace when runout or damage is detected.

For workshops and hobbyists maintaining FS-200S-class glow engines, OS44502000 provides a direct replacement crankshaft option; verify engine markings and follow safe workshop procedures during replacement and reassembly.
