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

FS-Series Pushrod Cover Overview

This O.S. Engine OS44666100 FSa-56 pushrod cover is designed to sit over the pushrod/valve train of FS-series RC engines, offering a simple protective barrier while you carry out assembly or maintenance. It limits exposure of the pushrod area to dust and incidental contact during workshop tasks.

Marketed as a replacement or spare for engines that call for an FSa-56 type cover, make sure the OS44666100 identifier matches your engine's parts list before purchasing. Installation typically uses the engine's original mounting hardware: align the cover to the opening and fasten with the existing screws, taking care not to overtighten small fasteners.

Although the cover does not influence engine timing or output, it helps keep the pushrod zone clean and stable during checks and tuning procedures, reducing the likelihood that debris will interfere with small engine mechanisms.
