The ROTAX 912 engine is provided with a dry sump forced lubri-
cation system with a main oil pump with integrated pressure regu-
lator (1) and oil pressure sensor (2).
The oil pump (3) sucks the motor oil from the oil tank (4) via the oil
cooler (5) and forces it through the oil filter (6) to the points of lu-
brication in the engine.
The surplus oil emerging from the points of lubrication accumula-
tes 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 (7) on the oil tank.
The oil temperature sensor (8) for reading of the oil inlet tempera-
ture is located on the oil pump housing.
