Lubrication system

See fig. 6.

The ROTAX 912 engine is provided with a dry sump forced lubrication sys-
tem with a main oil pump with integrated pressure regulator (

1

) and oil pres-

sure sensor (

2

).

◆

NOTE:

The oil pump is driven by the camshaft.

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 lubrication in the en-

gine.

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.

◆

NOTE:

The oil circuit is vented via bore (

7

) on the oil tank.

◆

NOTE:

The oil temperature sensor (

8

) for reading of the oil in-

let temperature is located on the oil pump housing.

Lubricants, see Chapter 10.2.3).
