Introduction
This section contains information about the complete
engine assembly. For specific engine technical
information refer to the technical data section.
Make sure that the correct engine service tools,
consumables and torque figures are used when you
perform service procedures.
Replacement of oil seals, gaskets, etc., and any
component that show signs of wear or damage, is
expected as a matter of course.
It is expected that components will be cleaned and
lubricated where required, and that any opened
hose or pipe connections will be blanked to prevent
excessive loss of hydraulic fluid, engine oil and
ingress of dirt.
Basic Description
The Perkins 400 series engines are indirect
injection engines. The engines are controlled with
a mechanically actuated fuel injection pump. The
engine cylinders are arranged in-line. The cylinder
head assembly has one inlet valve and one exhaust
valve for each cylinder. Each cylinder valve has a
single valve spring.
The crankshaft for the four cylinder engine has five
main bearing journals. End play is controlled by the
thrust washers that are located on the rear main
bearing.
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 crankcase.
The fuel injection pump is operated by lobes on the
camshaft. The fuel transfer pump is located on the
right hand side of the crankcase. 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 a Perkins distributor or a 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.

15 - 4 9813/6750-1 15 - 4
A gerotor oil pump is located in the centre 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 filter. 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 cooling pump. The
coolant is cooled by the radiator and the temperature
is regulated by a water temperature regulator.
Engine efficiency, efficiency of emission controls, and
engine performance depend on adherence to correct
operation and maintenance recommendations.
Engine performance and efficiency also depend on
the use of recommended fuels, lubrication oils, and
coolants. Refer to the Maintenance Schedules (PIL
78-24).
Health and Safety
Hot Components
Touching hot surfaces can burn skin. The engine and
machine components will be hot after the unit has
been running. Allow the engine and components to
cool before servicing the unit.
Turning the Engine
Do not try to turn the engine by pulling the fan or fan
belt. This could cause injury or premature component
failure.
Notice: The engine and other components could
be damaged by high pressure washing systems.
Special precautions must be taken if the machine is
to be washed using a high pressure system.Make
sure that the alternator, starter motor and any other
electrical components are shielded and not directly
cleaned by the high pressure cleaning system. Do
not aim the water jet directly at bearings, oil seals or
the engine air induction system.
WARNING! To bleed the injectors you must turn the
engine. When the engine is turning, there are parts
rotating in the engine compartment.Before starting
this job make sure that you have no loose clothing
(cuffs, ties etc) which could get caught in rotating
parts.When the engine is turning, keep clear of
rotating parts.
Notice: Clean the engine before you start
engine maintenance. Obey the correct procedures.
Contamination of the fuel system will cause damage
and possible failure of the engine.
Notice: Do not exceed the correct level of engine
oil in the sump. If there is too much engine oil,
the excess must be drained to the correct level. An
excess of engine oil could cause the engine speed
to increase rapidly without control.
WARNING! The engine has exposed rotating parts.
Switch off the engine before working in the engine
compartment. Do not use the machine with the
engine cover open.
WARNING! Hot oil and engine components can burn
you. Make sure the engine is cool before doing
this job.Used engine crankcase lubricants contain
harmful contaminants. In laboratory tests it was
shown that used engine oils can cause skin cancer.
Notice: A drive belt that is loose can cause damage
to itself and/or other engine parts.
WARNING! Do not open the high pressure fuel
system with the engine running. Engine operation
causes high fuel pressure. High pressure fuel spray
can cause serious injury or death.
CAUTION! It is illegal to pollute drains, sewers
or the ground. Clean up all spilt fluids and/or
lubricants.Used fluids and/or lubricants, filters and
contaminated materials must be disposed of in

Operation
The Four Cylinder Cycle
This section describes the cycle sequence for the 4
cylinder engine.
With the crankshaft positioned as shown, the pistons
in numbers 1 and 4 cylinders are at top dead centre
and pistons in numbers 2 and 3 cylinders are at
bottom dead centre.
It is important to note that number 1 cylinder is firing
and about to start its Power stroke. Rotating the
crankshaft a further full rotation would position the
pistons as described but the engine would be at a
different stage in its four stroke cycle, with number 1
cylinder about to start its Induction stroke.
Firing Order
A cylinder is said to be firing, when the fuel/air mixture
ignites and the piston is about to start its power
stroke.
From the stages described, it can be seen that
number 1 cylinder will be next to fire. Number 3
cylinder is starting its compression stroke and is next
in the cycle, followed by cylinders 4 and 2. The firing
order is therefore; 1, 3, 4, 2.
The stages in the four stroke cycle for each cylinder
are as follows:

Four Stroke Cycle
Induction
As the piston travels down the cylinder, it draws
filtered air at atmospheric pressure and ambient
temperature through an air filter and inlet valves into
the cylinder.
Compression
When the piston reaches the bottom of its stroke, the
inlet valves close. The piston then starts to rise up the
cylinder compressing the air trapped in the cylinder.
This causes the temperature and pressure of the air
to rise. Fuel is injected into the cylinder when the
piston is near to TDC (Top Dead Centre).
Power
The piston continues to rise after the start of fuel
injection, causing a further increase in pressure and
temperature.
The temperature rises to a point at which the fuel/air
mixture ignites. A cylinder is said to be firing when
the fuel/air mixture ignites.
This combustion causes a very rapid rise in
both temperature and pressure. The high pressure
generated propels the piston downwards turning the
crankshaft and producing energy.
Exhaust
Once the piston has reached the bottom of its travel,
the exhaust valves open and momentum stored
in the flywheel forces the piston up the cylinder
expelling the exhaust gases.
In a running engine, these four phases are
continuously repeated. Each stroke is half a
revolution of the crankshaft, thus, in one cycle of a
four stroke engine, the crankshaft revolves twice.

Introduction
The crankcase is the housing for the crankshaft.
The enclosure forms the largest cavity in the engine
and is located below the cylinders. It is integral with
the cylinder bank and forms an engine block. It has
an opening in the bottom to which an oil sump is
attached with a gasket and bolted joint.
The crankcase protects the crankshaft and
connecting rods from foreign objects it also keeps
the engine oil contained and allows the oil to be
pressurised and also provide the rigid structure with
which to join the engine to the transmission.

Introduction
In a piston engine, the main bearings are the
bearings on which the crankshaft rotates.
The bearings hold the crankshaft in place and
prevent the forces created by the piston and
transmitted to the crankshaft by the connecting rods
from dislodging the crankshaft, instead forcing the
crank to convert the reciprocating movement into
rotation.

15 - 46 9813/6750-1 15 - 46
Check (Condition)
Check the condition of the main bearings by
measuring the clearance between the two bearing
halves.
If the crankshaft journals and the bores for the
crankcase and connecting rods were measured,
no further checks are necessary. If the bearing
clearance measurement is necessary, the use of
the plastic gauge is an acceptable method. The
plastic gauge is less accurate on journals with small
diameters if the clearances are less than 0.1mm.
When you use the plastic gauge make a note of the
following:
• Make sure that the backs of the bearings and
the bores are clean and dry.
