COMPONENTS
A. Oil Pump
The oil pump is a simple gear pump driven by
crankshaft.
The main function of the oil pump is to circulate oil
through the engine movable components. It sucks
the oil from the oil sump through a strainer which
prevents entrance of any particles into the pump,
and supplies to the oil gallery.
To keep the oil pump from building up too much
pressure, a relief valve is also fitted to the oil pump.

B. Oil Filter
The oil filter used is a
“SPIN ON TYPE”
fitted to the
oil cooler.
The main function of oil filter is to filter all contami-
nants that get ingested into the engine, along with
traces of worn out metals from bearings and other
internal parts.
The oil enters the oil filter under pressure through
the holes on the perimeter of the base plate.
The oil then passes through the filter element where
it is "cleaned", and then flows to the central tube
and back into the engine, oil gallery.
C. Oil Strainer
The oil strainer is fitted to the oil pump, through
which the oil is drawn from oil sump and supplied to
the oil gallery. The strainer acts like a filter and
blocks the contaminants from entering the oil pump.
