O.S. Engine OS45266111 FS-40 Pushrod Protector  [OS45266111]

Protective Pushrod Cap for FS-40

This component, catalogued as O.S. Engine OS45266111, is a purpose-built replacement part for the FS-40 engine assembly. It keeps the pushrod area contained and aligned on FS-40 engine units, reducing the chance of misalignment while you work on small-scale RC nitro engines.

Fitting is simple: access the pushrod zone by removing the engine head or specified cover, set the protector over the pushrod assembly, and secure it using the engine's original attachment points and fasteners. Use hand torque as recommended and confirm the pushrod moves freely before completing reassembly.

For workshop tuning and routine care, the protector forms a stable enclosure around the pushrod route to lower the risk of dirt ingress and inadvertent displacement. It serves purely as a maintenance and protection item and will not change engine timing or tuning settings.
