Oil Pump

WARNING: This page is about a different car, the 2018 Land Rover Range Rover, 2017 Land Rover Range Rover, and 2016 Land Rover Range Rover. However, it is still accessible from the selected car via links, so may be relevant.

The oil pump is a G-rotor 2-stage pressure pump with solenoid control to switch between low and high pressure modes depending on engine speed and load to optimize fuel economy.

It is bolted to the front of the cylinder block. It is sealed by means of a gasket, which is recessed into the oil pump housing. The pump intake and outlet ports align with oil passages in the cylinder block.

The pumping element is an eccentric rotor, which is directly driven by flats on the crankshaft. An integral pressure relief valve regulates pump outlet pressure at 4.5 bar (65.25 lb/in² ).

The front crankshaft oil seal is housed in the oil pump casing and is fitted such that its front face is 1 mm (0.04 in) under flush with the machined front face of the oil pump.

NOTE: The seal is not to be pushed all the way into the bore as this will block the seal drains.
