LR3/Disco 3
With the exception of the pump and level gauge, all oil system components are installed on the sump.
Oil Pick-up
The moulded composite oil pick-up is immersed in the oil reservoir to provide a supply to the oil pump during all normal
vehicle attitudes. The castellated inlet allows the supply to be maintained even if the sump pan is deformed (e.g. by
'grounding'). A mesh screen in the inlet prevents debris from entering the oil system.
Oil Pump
The oil pump is a gear type pump and is bolted and dowelled to the front of the engine block. It is sealed by means of a
rubber gasket, which is recessed into the oil pump housing. The pump inlet and outlet ports align with oil passages in the
ladder frame.
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 Psi).
The front crankshaft oil seal is housed in the oil pump casing and is fitted such that its front face is 1mm underflush with
the machined front face of the oil pump.
NOTE :
Oil Filter
The oil filter is a replaceable cartridge installed on an adapter in the centre of the 'vee'. An internal bypass facility permits
full flow bypass if the filter is blocked.

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