FS Engine Cam Cover Replacement - OS44601100 by O.S. Engine  [OS44601100]

Service cam cover summary

This cam cover is sold as O.S. Engine CAM COVER FSa-56 and carries model number OS44601100. It is intended as a direct replacement for FS-series RC engines identified by FSa-56, serving as a serviceable component for maintenance and repair on RC-scale engines.

Installation and fitment: remove the existing cover, ensure mating surfaces are clean and free of debris, fit the replacement cover and tighten fasteners evenly to achieve a flat seal. Reuse the original gasket or seal when applicable and follow the engine maker's recommended fastener sequence and torque values if those are available.

Tuning and maintenance role: the cam cover protects valve train parts and preserves internal sealing, so correct seating and regular inspections help maintain timing component condition during tuning and track use. Keep the surrounding area free of fuel and oil accumulation and recheck fasteners after the initial run-in.
