FSa-56 Pushrod OS44666000 for FS Engines by O.S. Engine  [OS44666000]

Pushrod FSa-56 for FS-series Engines

This replacement pushrod from O.S. Engine is intended for RC model FS engines and is used where an FSa-56 specification is required. It links the rocker assembly to the valve actuation mechanism on glow engines in the FS family.

Compatibility is focused on FS engine parts; verify the pushrod part number on your engine before fitting. As a mechanical linkage, it contributes to adjustments in valve timing and clearance during engine setup.

Before installing, examine the mating surfaces and rocker pins for wear, make sure the pushrod moves freely without binding, and confirm full-stroke clearance. Ensure retaining clips or pins are correctly seated for secure operation on your model engine.
