General characteristics
The lubrication system is divided into two sections:
- High pressure
- Low pressure
The high pressure section includes all components located on the engine crankcase whereas the low
pressure section only refers to the thermal group.
The trochoidal pump is installed in the sump and is controlled by a pair of gears.
To guarantee the integrity of the pump, a pre-filter is fitted.
This is a screw-in type pre-filter and the relevant plug serves at the same time as an engine oil drain
plug.
