Gerotor Pump; Oil Pressure Regulator Valve - International VT 275 V6 Manual

Gerotor Pump

• The gerotor style oil pump is integrated
into the front cover with the gear set driven
off two flats on the nose of the crankshaft.
The gear set rides directly on the surface
of the crankcase front cover.
• The gears are a matched set, and should
be marked before disassembly so they can
be reassembled with the same side
facing out.
• The oil pump front cover is located with
two dowel pins and sealed with a press-in-
place gasket.

Oil Pressure Regulator Valve

• The oil pressure regulator valve is
responsible for regulating the maximum
pressure in the lubrication system. The
regulator, which can be removed with the
engine in the chassis, is located in the front
cover just below the gerotor oil pump cover.
• The face of the regulator piston is exposed
to the pressurized oil. When pressure
exceeds 75 psi, the piston is depressed
against spring pressure enough to expose
a port that allows excess oil to be relieved
to the suction side of the pump.
