The timing gears are stamped with timing marks in
order to ensure the correct assembly of the gears.
When the No. 1 piston is at top center compression
stroke, the teeth that are stamped on the crankshaft
gear and the camshaft gear will be in alignment with
the idler gear.
The crankshaft gear turns the idler gear which then
turns the camshaft gear and the gear for the engine
oil pump.
The fuel injection pump is mounted in the cylinder
block. The fuel injection pump is operated by lobes
on the camshaft. The fuel transfer pump is located
on the right hand side of the cylinder block. The
fuel transfer pump is also operated by lobes on the
camshaft.
The fuel injection pump conforms to requirements
for emissions. If any adjustments to the fuel injection
pump timing and high idle are required you must
refer to your Perkins distributoror your Perkins
dealer. Some fuel injection pumps have mechanical
governors that control the engine rpm. Some fuel
injection pumps have a governor that is electrically
controlled.
A gerotor oil pump is located in the center of the idler
gear. The engine oil pump sends lubricating oil to the
main oil gallery through a pressure relief valve and an
engine oil
fi
lter. The rocker arms receive pressurized
oil through an externally located oil line that runs from
the main oil gallery to the cylinder head.
Coolant from the bottom of the radiator passes
through the belt driven centrifugal water pump. The
coolant is cooled by the radiator and the temperature
is regulated by a water temperature regulator.
Engine ef
fi
ciency, ef
fi
ciency of emission controls, and
engine performance depend on adherence to correct
operation and maintenance recommendations.
Engine performance and ef
fi
ciency also depend on
the use of recommended fuels, lubrication oils, and
coolants. Refer to the Operation and Maintenance
Manual, “Maintenance Interval Schedule” for more
information on maintenance items.
