What should be done to the camshaft before installation?

Before installing a camshaft, it is essential to lubricate the bearing surfaces and lobes. This lubrication minimizes friction during initial startup and ensures that the camshaft operates smoothly. Proper lubrication helps prevent damage to both the camshaft and the associated components, which can occur if they run dry when the engine is first started after installation.

While other actions may also be important during the camshaft installation process, lubricating the surfaces is crucial as it directly impacts the immediate performance and longevity of the engine. Ensuring that all moving parts are properly greased reduces the risk of wear and can help avoid costly repairs later on. Proper lubrication is a fundamental step in engine assembly that contributes significantly to its reliability and efficiency.
