2. DESCRIPTION AND ASSEMBLY
The oil level controller is a mechanical actuator placed on the oil sump at the bottom of the engine. It is equipped
with a floater inside a small reservoir which opens or closes the oil flow into the engine crankcase.
When assembling the level controller in the sump, the latter is equipped with a universal bracket with two screws
whose task is not only to secure the unit to the engine but to adjust the height thereof such that with the engine
running and oil hot, the indicator level should be aligned with the oil level in the engine crankcase.
Therefore, the height from the adjusting nut to the oil sump base will vary according to the engine model.
Variations with respect to its height or position on the engine can cause the oil sump to overfill. It is also important
to tighten the fasteners correctly to prevent engine vibrations from altering the position of the oil controller (see
enclosed table).
1 Oil supply hose
2 Venting hose
3 Oil controller hose to oil sump
4 Height adjustment screw
As the automatic filling equipment is connected by a hose to the oil sump, the oil level displayed always matches
the actual reading, whether in applications where ventilation airs to the atmosphere or for applications with
crankcase gas recirculation to intake. This crankcase ventilation hose (2) must be 12mm in diameter and the
connection must be located above the oil level. Improper installation of crankcase ventilation can cause overflow.
The discharge hose to the crankcase (3) should be approximately 25mm in diameter and should be free from
buckling.
The charging hose (1) should have a downward pitch with no sags and be 12mm in diameter.
If fed from a booster tank, the height thereof must NOT exceed 4.6 m. If this height is exceeded, the oil sump may
overfill due to excess inlet pressure.
