O.S. Engine OS42501100 Cam Cover FSa-155  [OS42501100]

Replacement cam cover for FS engines

This cam cover is an RC-scale engine accessory listed as O.S. ENGINES CAM COVER FSa-155 and intended for use within the FS Engine parts family. It serves as the external cover for the cam area and is offered as a direct replacement component for the FSa-155 designation.

Fit and role: the cover protects the camshaft/timing area from debris and helps retain gasket seals during routine servicing. It is presented as a spare part to restore correct external assembly and to support consistent engine access during maintenance and minor tuning work on FS-series RC engines.

Installation notes: this description focuses on compatibility and functional role rather than step-by-step procedures. Confirm fit against the FSa-155 marking and verify alignment with existing mounting points before reassembly. Use matching fasteners and standard RC workshop practice to ensure correct sealing and clearance.
