FSa-56 Pushrod Cover for FS Engines - O.S. Engine OS44666100  [OS44666100]

FS-Series Pushrod Guard

This O.S. Engine OS44666100 FSa-56 pushrod cover is intended to guard the pushrod region of FS-series RC engines during build and maintenance sessions. The cover sits over the valve train opening to minimise dirt ingress and accidental contact while you work on the engine.

Offered as a replacement or spare dress-up part for applications calling for an FSa-56 style cover, buyers should match the OS44666100 number to their engine parts list before purchase. For installation, reuse the engine's original screws: set the cover in place, align the holes, and fasten evenly to avoid putting undue stress on the mounting threads.

The cover does not affect timing or engine output, but it helps keep the pushrod area free of contaminants when tuning, checking needles, or carrying out fine adjustments, which reduces the chance of debris compromising small engine components.
