Oil pump drives transfer rotational power from the engine’s crankshaft or camshaft to the oil pump, ensuring consistent lubrication throughout the engine. These components are integral to the engine’s oiling system, found in both gasoline and diesel applications. Drive mechanisms utilize various methods including direct drive, intermediate shafts, and eccentric drives, dictated by engine design. Key features include hardened steel construction for durability under high loads and precision machining for accurate timing and oil delivery. Component variations exist to accommodate different oil pump designs and engine configurations, requiring specific fitment for optimal performance.
