O.S. Engine OS45266010 Pushrod FS-40S pushrod for FS engines  [OS45266010]

FS pushrod for O.S. engines

This pushrod is an RC-scale replacement part intended for use with O.S. FS-series engine assemblies, serving the valve linkage between rocker and valve mechanism in nitro model engines.

Designed for routine maintenance and setup adjustments, the component supports discrete tuning steps such as valve lash and idle timing without changing core engine components.

Installation notes: verify correct orientation and secure clevis or retainer at both ends, inspect associated ball bearings and linkage pins for wear, and perform final checks at low throttle before full operation.

Maintenance tips: keep linkage points clean, check for bending or play after hard use, and replace the pushrod if any deformation or excessive wear is found to maintain predictable valve actuation.
