O.S. Engine OS44307000 FSa-72 Replacement Cover Plate  [OS44307000]

Service Cover for FSa-72 Engines

This component is catalogued as O.S. Engine OS44307000 and is intended for use with parts marked FSa-72. It provides a sealed covering for the crank case area and a secure mounting interface for adjoining engine parts.

Installation notes: fit the plate onto the crank case using existing dowel pins and the original screw holes; where possible reuse the factory fasteners to preserve alignment. During installation, check that the plate does not contact the carburettor or cooling head on the FSa-72 configuration.

Maintenance and durability: the cover contributes to reliable crankcase sealing, which affects starting and idle stability on RC engines. Inspect for flatness, confirm fastener torque, and ensure sealing faces and gaskets are clean and intact before running the engine.
