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

Aluminium Pushrod Cover for FS Engines

This O.S. Engine OS44666100 pushrod cover FSa-56 is an accessory made to protect the pushrod area of FS-series RC engines while you assemble or perform routine maintenance. The cover fits over the pushrod and nearby valve train to reduce exposure to dirt and accidental contact during hands-on work.

The item serves as a direct replacement or spare for engines specifying FSa-56 style covers; always verify the part number against your engine service parts list before purchasing. Installation is simple when reusing the engine's original mounting hardware: place the cover over the pushrod opening, line up the mounting holes, and secure with the existing screws while avoiding overtightening to protect small threads.

While the pushrod cover does not change engine timing or power, it keeps the pushrod area tidy and stable during inspections, needle adjustments, and other fine tuning operations, lowering the risk of debris affecting delicate engine components.
