O.S. Engine OS45266010 Pushrod for FS-40S and FS Engines  [OS45266010]

Replacement Pushrod for O.S. FS Engines

This pushrod is a direct RC replacement for O.S. FS-series engine assemblies, linking the rocker to the valve for nitro model engines.

Built to assist routine maintenance and tuning, it enables fine adjustments such as valve lash and idle timing without swapping out core engine components.

Installation notes: confirm correct orientation, fasten the clevis or retainer at both ends, inspect ball joints and linkage pins for wear, and perform a low-throttle check before full operation.

Maintenance tips: keep linkage areas free of grime, watch for bends or free play after heavy runs, and replace the pushrod if any deformation or excessive wear appears to preserve consistent valve motion.
