This crankshaft is supplied under the O.S. Engine OS23102000 designation and intended for the 35AX line. The paragraphs below outline compatibility checks, installation pointers, and the crankshaft's role during engine rebuilds and tuning for RC applications.
As the rotating core, the crankshaft converts piston travel into rotational output within the engine case; in hobby use it is treated as a precision spare. Before fitting, verify the OS23102000 part number against your engine casting and internal layout to ensure correct alignment with bearings and the connecting rod interface.
Installation guidance: inspect mating surfaces and running clearances, replace seals and bearings where required, and follow the engine manual for correct torque values on retaining hardware. After assembly perform a controlled break-in following standard RC engine procedures and re-check endplay and smooth rotation.
Tuning impact: a crankshaft does not change ignition or fuel settings directly, but imbalance, wear, or poor fit can introduce vibration, shorten bearing life, and alter perceived throttle response, so crank condition is important when diagnosing performance or reliability issues on models.
Keep the OS23102000 crankshaft and related components clean during assembly, confirm correct fit with the engine case and bearings, and monitor rotation and endplay during initial runs to ensure reliable RC operation.
