ROTAX 912 iS LUBRICATION SYSTEM
The engine is provided with a dry sump forced lubrication system with a
camshaft driven pump with an integrated pressure regulator. The pump delivers
oil from the oil reservoir, through an oil cooler (radiator) and oil filter to points
of lubrication.
Surplus oil emerging from the points of lubrication gathers at the bottom of the
crankcase from where it is forced back to the oil reservoir by piston blow-by
gasses.
Oil temperature is sensed by a sensor located on the crankcase.
The lubrication circuit is vented at the oil reservoir. The oil reservoir is mounted
on the firewall.
Refer to the latest revision / edition of the Rotax 912 iS engine operator
and maintenance manuals.
The lubrication system volume is approximately 3.5 liters (7.4 pints).
