Pumping unit, located on the cross member below the fire wall. The pump
unit works automatically as soon as the engine speed is above 300 RPM.
The pump unit consists of a pumping element for feeding oil from tank (13)
into the engine oil pan. The second pumping element withdraws oil from
the engine oil pan and feeds it back into the reserve tank when the oil level
in the oil pan exceeds the maximum running oil level. The combined oper-
ation of the pumping elements maintains an optimal oil level in the engine
oil pan. Oil drawn off by the Centinel burn system is also replaced through
the supply system "Reserve".
