2.3 Lubrication
The lubrication system of the ELBA is connected to the low-pressure oil system of the
engine. In the housing (1, Fig. 4) lubricating oil (3) flows through the pipes (2) to the
shafts to lubricate the gear wheels. Oil that is not used flows through the oil return to
the crankcase.
Note: Damage to the gear wheels can occur if the oil supply to the ELBA
system stops.
