O.S. Engine OS44366000 Pushrod FSa-72 for FS engine parts  [OS44366000]

Pushrod for FS engine linkages

The O.S. Engine OS44366000 Pushrod FSa-72 is a dedicated RC-scale pushrod intended for FS engine part assemblies. It serves as the mechanical linkage between valve actuation components and external control linkages, providing a straightforward replacement option when restoring or maintaining FS-series model engines.

In practical use the pushrod's role is limited to transferring motion and maintaining correct geometry in the valve train or throttle linkage depending on the engine layout. When replacing a pushrod, confirm the rod length and end fittings match the original component to preserve valve timing and clearance; improper fit can affect idle stability and throttle response on model engines.

Installation notes: mount the pushrod so it has minimal lateral play, verify both ends seat correctly, and check for binding throughout the servo throw or linkage travel range. Routine checks after the first run-in and following any impacts will help detect bending or wear early, protecting other engine parts and maintaining reliable operation.
