GF40 Cam Cover Direct-Fit for O.S. Engine OS49401100  [OS49401100]

Cam cover providing service access to GF40 cam area

This cam cover fits the O.S. Engine GF40 series nitro engines. It provides protected access to the cam area so you can inspect timing components and carry out routine adjustments without disturbing other engine systems.

The design prioritizes serviceability: remove the factory cover to reach the cam and related drive parts, verify alignment, and refit the cover to secure the assembly. Keep mating surfaces clean and follow the engine's service intervals when opening the case to avoid disturbing sealed components.

When preparing or tuning a vehicle, the cam cover simply enables safe inspection and small setup tweaks at the track or workshop; it does not change engine output by itself. Use it as part of standard maintenance before running a GF40-powered RC model.
