In this video, I will show you the way we can check the condition of A320 CFM56-5B oil system. I will try to explain how distribution works.
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.

*********video is just for information purposes always stick to the latest maintenance manual. For this purpose, I didn´t record one removal/installation step*********
