O.S. Engine OS45266010 FS-Series Valve Pushrod  [OS45266010]

Service Pushrod for O.S. FS Engines

This pushrod serves as an aftermarket replacement for O.S. FS-series engine assemblies, transferring motion from the rocker to the valve in nitro model engines.

It helps with workshop adjustments and tuning tasks such as valve lash and idle trimming while leaving the engine's primary components unchanged.

Installation notes: fit cold, verify correct orientation, secure the clevis or retainer at both ends, inspect associated bearings and linkage pins for wear, and confirm operation at low throttle before full use.

Maintenance tips: keep linkage interfaces clean, check for bends or excess play after heavy use, and replace the pushrod when deformation or pronounced wear is present to preserve consistent valve timing.
