LUBRICATION SYSTEM
The engine lubrication system is a self-contained, pressure-regulated
and recirculating dry sump system. The system supplies filtered and
pressurized oil to the various engine oil coolers, engine sumps and the
accessories gearbox, at the proper temperature, to cool and lubricate
the bearings, seals, and gear meshes.
The main subsystems of the oil system are: lubricating oil-supply,
engine sumps, lubricating oil scavenge and lubricating oil vent.
LUBRICATING OIL-SUPPLY SYSTEM
Oil is supplied to the lube and scavenge pump from a pressurized oil
tank and is pumped through an oil filter. The oil is then cooled while
passing through two heat exchangers (ACOC and FCOC). Oil pressure
is controlled by a pressure-regulating valve in the pump housing. A
tank pressurizing valve maintains positive pressure in the oil tank to
ensure an adequate oil supply to the lube and scavenge pump, and
proper oil pressure at altitude. A separate Tank Vent Valve protects the
tank from over-pressurization. Oil to the accessory gearbox is
distributed through cast passages to the various gear meshes and
bearings. Pressurized oil is divided inside the front frame and routed to
the fan and front sumps. An external tube delivers oil from the front
frame to the compressor diffuser and the rear turbine-bearing support.
The main components of this subsystem are as follows: oil tank, lube
and scavenge pump, oil filter unit, air-cooled oil cooler (ACOC) and
fuel-cooled oil cooler (FCOC).
OIL TANK
The oil tank is designed to store a sufficient amount of oil (12 quarts)
for lubrication of the engine and the accessory gearbox. The tank has
an oil level sight gage and an oil level/low level warning sensor. These
sensors allow the oil level to be continuously read remotely, and
includes a switch that is actuated when there are 5 quarts or less of
usable oil remaining in the tank. A screen on the oil outlet and a chip
collector plug at the tank bottom are protective devices that prevent
debris from recirculating. The tank is protected from over-
pressurization by the externally vented Pressure Relief Valve.
