Cam Cover for FS Engines OS44901100 by O.S. Engine  [OS44901100]

FS engine cam cover overview

Designed for service use, the O.S. Engine OS44901100 cam cover is a replacement component compatible with FS-series RC engines. It is intended to protect the cam assembly and simplify part renewal during routine servicing.

Compatibility is tied to the FS engine family in the O.S. Engine parts catalogue; confirm the OS44901100 part number against your engine diagram to ensure the cam housing interface and screw positions correspond.

Fitting guidance: remove the upper casing and associated components to gain access to the cam housing, keep original fasteners where feasible, and reassemble to recommended torque settings. Carry out work on a clean bench, use the correct hex drivers, and check sealing faces or gaskets for wear while reassembling.

Maintenance role: the cover gives controlled access for inspection and cleaning of the cam area and helps maintain component longevity. It is not a performance modification but a maintenance item to support reliable operation.
