FS Pushrod Replacement FSa-72 for FS Engines - O.S. Engine OS44366000  [OS44366000]

FS Engine Pushrod Linkage

The O.S. Engine OS44366000 Pushrod FSa-72 is a purpose-built RC-scale pushrod for FS engine assemblies. It serves as the mechanical connector between valve actuation components and external control linkages, offering a straightforward service part for restoring or maintaining FS-series model engines.

In operation the pushrod simply transmits motion and helps preserve the correct geometry of the valve train or throttle linkage depending on the engine layout. When replacing the part, confirm rod length and end fittings match the original item to keep valve timing and clearances correct; an incorrect fit can cause idle instability or impaired throttle response on model engines.

Installation notes: fit the pushrod with minimal lateral play, make sure both ends seat properly, and check for binding through the full servo throw or linkage travel. Carry out routine inspections after the first run-in and after any impacts to spot bending or wear early and protect other engine components.
