2.3.14 Engine lubrication system scheme
2.3.14.1 Lubrication system description
The Rotax 912 engine is provided with a dry sump forced lubrication system. The oil pump pulls
the motor oil from the oil tank attached to the firewall via the oil cooler. Then forces it through the
oil filter to the lubrication points in the engine.
The surplus oil emerging from the lubrication points accumulates on the bottom of the crankcase
and is forced back to the oil tank by the blow-by gases.
The oil tank is equipped with a vent hose.
The engine lubrication system is further described in documentation supplied with the engine.
