Camshaft for FS engines

This camshaft is the FSa-110 replacement part offered under O.S. Engine OS44962000. The text below focuses on practical details relevant to modelers who maintain or tune RC glow engines, outlining fit considerations, installation basics, and the part's role in engine timing and performance balance.

Compatibility and role: intended as a camshaft spare for FS-series engine maintenance and rebuilds, the component governs valve timing and lift characteristics; when replacing the camshaft, check endplay and timing marks to preserve correct ignition and valve events.

Installation notes: inspection of the cam lobe surfaces and camshaft journal fit is recommended before reassembly, use proper bearings or bushings as per the engine manual, and confirm clearances with the cylinder head and valve train while rotating the engine by hand.

Tuning impact: camshaft condition affects breathing and low-to-mid rpm response, so replacing a worn camshaft can restore original timing characteristics without altering carburetor or ignition settings.

Use this camshaft as a direct service part during engine overhaul or when restoring valve timing consistency; verify fit against your engine variant before final assembly.
