Linkage Rod for FS Series

The O.S. Engine OS44366000 Pushrod FSa-72 functions as an RC-scale linkage rod designed for FS engine part assemblies. It reconnects valve actuation or throttle components to external controls and is intended for use when servicing FS-series model engines.

Its role is straightforward: transfer motion while maintaining the designed geometry of the valve train or throttle linkage based on the engine layout. Always confirm rod length and the shape of end fittings before installation to keep valve timing and clearances within spec; a mismatch can cause unstable idle or sluggish throttle action.

Fitting advice: position the pushrod to have minimal lateral play, confirm both ends are correctly seated, and check the linkage through the full range of movement to ensure there is no binding. Reinspect after the first run and after any knocks to catch bending or wear early.
