General characteristics
Lubrication circuit is split into two sections:
- High pressure
- Low pressure
The high pressure section includes all components located on the engine crankcase, while the low
pressure section only refers to the thermal unit.
The trochoidal pump is installed into the sump and is controlled through a couple of gears.
To guarantee the integrity of the pump, a pre-filter is installed.
The pre-filter is of the screw-in type and the plug serves at the same time as an engine oil drain plug.
