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

Designed for FS Engine Linkages

The O.S. Engine OS44366000 Pushrod FSa-72 is made as an aftermarket pushrod for FS engine assemblies, intended to reconnect valve actuation components with control linkages. It provides a simple replacement option for hobbyists working on FS-series model engines.

Functionally the pushrod transmits motion while helping to maintain correct valve train or throttle linkage geometry according to the engine layout. Before fitting, confirm length and end fittings match the original component to avoid altered valve timing or clearance that could degrade idle stability or throttle feel.

Installation guidance: install so lateral play is kept to a minimum, confirm both end fittings seat properly, and test the linkage through full servo travel for any binding. Inspect the pushrod after the first run and after impacts to detect bending or wear early.
