Study Notes
Oil System Overview
- The O-200-A series engines use a wet-sump, pressure-lubricating oil system.
Oil Flow Path
- Oil in the sump passes through the sump pickup tube and suction screen to the oil pump's suction side.
- From the oil pump's pressure side, oil is fed through the pressure oil screen or external full-flow oil filter into the left oil gallery.
- If an oil cooler is installed, oil flows through the oil cooler bypass valve, then to the cooler via a flexible hose connection, and back to the engine via a second flexible hose connection.
Oil Distribution
- Oil flows forward through the left gallery, across the crankcase, and into the right gallery through passages connected by the camshaft front journal groove.
- The right gallery is closed by the oil pressure relief valve at its rear end.
- The galleries pressure-feed the main bearings, camshaft bearings, and hydraulic tappets.
