Lubrication
Conceptual diagrams
The lobe pump «F» sucks the oil from the sump, through the mesh pre-filter «C», it pushes it into the
cartridge filter «E» where there is also a safety valve «D».
Through the suitable passages found in the crankcases, the oil enters the crank chamber «G» where
the main bearings are lubricated and the big end (with high pressure), the piston pin and connecting
rod small end via spray «H».
Afterwards, the oil, through a nozzle «M» whose function is to reduce the flow rate, reaches the timing
system where it lubricates the camshaft «A» and from there, the valves and rockers. The oil passes
through the timing chain duct and returns to the sump «B» by gravity.
In the system there is a minimal oil pressure sensor «I» and a spray that serves to lubricate the stator
«L».
