The engines is provided with a dry sump forced lubrication sys-
tem with a main oil pump with integrated pressure regulator.
The airframe manufacturer is responsible for the main layout
and the component selection for the lubrication system.
The main oil pump sucks the motor oil from the oil tank via oil
radiator and forces it through the oil filter to the points of
lubrication.
NOTE
The oil radiator is optional.
The surplus of oil emerging from the points of lubrication accu-
mulates on the bottom of crankcase and is forced back to the oil
tank by the piston blow-by gases.
The oil pumps are driven by the camshaft.
The oil circuit is vented via bore on the oil tank.
The oil temperature sensor for reading of the oil inlet tempera-
ture is located on the oil pump housing.
