1. General
The lubrication system of one engine is completely self-contained and separated from the other engine or aircraft fluid systems.
Oil is distributed to components requiring lubrication and cooling by a lubrication pump element. Distribution is controlled by nozzles which direct oil at each component.
Scavenge pump elements in the pump remove oil from the engine bearing sumps and gearboxes and return the oil to the tank through the servo fuel heater and main oil/fuel heat exchanger to cool the returning oil.
