Lubrication System

The lubrication system has a large supply line with a strainer which prevents large contaminants from reaching the oil pump.

The oil pump (1) is driven by the crankshaft. The oil pump is a rotor pump with integrated pressure control valve. The valve opens at approximately 5.0 bar and prevents excessively high pressure which could damage the oil cooler.

The oil cooler is a flat oil cooler. The space for oil and coolant is divided alternately between the plates.

The oil filter (2) is a loose filter element placed in a housing. The overflow valve for a blocked filter is in the cover.
