13.1) Description of the system
See Fig. 33.
The ROTAX 914 engine is provided with a dry sump forced lubrication system with
a main oil pump with integrated pressure regulator and an additional suction pump.
◆ NOTE: The oil pumps are driven by the camshaft.
The main oil pump sucks the motor oil from the oil tank (1) via the oil cooler (2) and
forces it through the oil filter to the points of lubrication (lubricates also the plain
bearings of the turbo charger and the propeller governor).
The surplus oil emerging from the points of lubrication accumulates on the bottom of
crankcase and is forced back to the oil tank by the blow-by gases.
The turbo charger is lubricated via a separate oil line (3) from the main oil pump.
The oil emerging from the lower placed turbo charger collects in the oil sump and is
pumped back by a separate pump to the oil tank via the oil line (4).
◆ NOTE: The oil circuit is vented via nipple (5) in the oil tank.
For the completion of the lubrication system only the following connections need to
be established:
