POWER PLANT
 
ENGINE OIL SYSTEM
The function of the oil system is to lubricate and cool the engine bearings and gears. The system is a full flow recirculating type.
The oil for the engine is stored in a tank, which is an integral part of the accessory gearbox. An oil pump takes the oil from the tank to supply the front bearing chamber, the rear bearing chamber and the accessory gearbox, via an oil pressure filter and a fuel cooled oil cooler (FCOC). An oil replenishment tank is located in the aft equipment bay.

OIL TEMPERATURE PUMP BULB
The oil quantity transmitter provides indication to the STATUS page

and will
display an OIL LO QTY message if the oil quantity is low.
The pump supplies pressure to move the oil to the bearings and drive gear and to return it to the
tank. The oil pressure transducer provides an indication of the pressure between the oil feed and

scavenge lines and displays it on EICAS.
If the oil pressure is low, while the engine is running, an OIL LO PRESS message is displayed on


EICAS.

Oil is fed to the pressure filter. The filter removes debris prior to delivery to the bearing/gears. A pressure relief bypass valve allows oil to bypass the filter in the event of filter blockage and an OIL FILTER message will be displayed on EICAS, indicating an impending bypass.

Oil Replenishment System
Each engine oil tank capacity is 13.6 US qts (12.86 liters). Engine oil level is measured using a sensor (oil probe) which is located in the engine oil tank and provides quantity information on the STATUS display.

ENGINE OIL TANK
An oil replenishment tank is located in the aft equipment bay and contains an electrical pump and sensor probe for quantity level. The oil replenishment tank volume contains 6 US quarts (5.7 liters). The oil replenishment system is designed for ground use only and serves both main engines and the APU.
The system can be operated using the battery or external electrical power. Oil level monitoring is required during servicing the engine(s) to verify that the system stops when the full level is reached. It is recommended to stop replenshment manually when gauge reads 11.0 quarts.
The oil filling system is operated through the oil replenishment panel located on bulkhead 280 (left side behind the pilot’s seat) in the flight compartment. The panel will display all lights for a period of three seconds when the panel is powered up.
