DISTRIBUTION
Oil System
Oil is drawn from the sump through a suction tube to the intake side of the engine driven, gear type, oil
pump. Outlet oil is directed to a full flow replaceable element oil filter. A bypass valve is incorporated in
the filter. The oil pump has an oil pressure relief valve in the housing. A second gear driven pump located
below the starter, scavenges oil from the turbochargers.
Engine oil is cooled by ram air passing through the oil cooler on the rear of the engine. Oil is distributed
throughout the engine providing lubrication, cooling and oil supply to the propeller governor. Oil
temperature and pressure information is available from the combination gauge on the bottom right of the
pilot’s instrument panel. Engine crankcase gases are discharged to an air/ oil separator behind the oil
cooler and are then vented out the left exhaust stack.
