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 Kubota engine is a 4 cylinder diesel engine
in which the fuel is ignited by compression ignition
(C.I.). The engine operates on a four stroke cycle.
The engine is started by an electric starter motor. The
starter motor turns the engine via a pinion and teeth
on the engine flywheel.
When the engine runs the crankshaft drives the
camshaft though the gears. The camshaft opens and
closes the inlet and exhaust valves and through push
rods in time with the four stroke cycle. The engine
has 16 valves, 2 inlet and 2 exhaust valves for each
cylinder.
The crankshaft also drives a mechanical high
pressure fuel pump via gears. The pump is part of the
electronically controlled common rail fuel injection
system.
Air is drawn into the engine through the inlet
manifold and exhaust gases exit through the exhaust
manifold.
A mechanical lubrication oil pump is driven by the
crankshaft through gears. The pump pressurises
and circulates oil for engine lubrication and cooling
purposes.
A drive belt again driven by the crankshaft, drives a
coolant circulation pump and alternator.
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

The Four Stroke Cycle - 4 Cylinder
Engine
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.
The stages in the four stroke cycle for each cylinder
are as follows:

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.

Four Stroke Cycle
Induction
As the piston travels down the cylinder, it draws
filtered air through 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 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 downward 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.

This section describes the cycle sequence for the 3
cylinder engine.
The engine will have a power stroke once every 240°
of crankshaft angle (720°/3 = 240°).
With the crankshaft positioned as shown, the piston
in number 2 cylinder is at TDC and pistons in number
1 and 3 cylinders are 32° past bottom dead centre
(BDC).
It is important to note that number 2 cylinder is
firing and about to start it's power stroke. Rotating
the crankshaft a further 360° would position the
pistons as described. However the engine would be
at a different stage in it's four stroke cycle, with the
number 2 cylinder about to start its induction stroke.

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 the
number 2 cylinder will be next to fire. The number 1
cylinder is in the middle of its compression stroke and
number 3 cylinder is in the middle of exhaust stroke.
The firing order is therefore; 1, 3, 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.
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

Clean
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: 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.
Before carrying out any service procedures that
require components to be removed, the engine must
be properly cleaned.
Cleaning must be carried out either in the area of
components to be removed or, in the case of major
work, or work on the fuel system, the whole engine
and surrounding machine must be cleaned.
Stop the engine and allow it to cool for at least one
hour. DO NOT attempt to clean any part of the engine
while it is running.
1. Make sure that the electrical system is isolated.
2. Make sure that all electrical connectors are
correctly coupled. If connectors are open fit the
correct caps or seal with water proof tape.
3. Cover the alternator with a plastic bag to prevent
water ingress.
4. Seal the engine air intake, exhaust and breather
system.
5. Make sure that the oil filler caps and dipstick are
correctly installed.
6. Use a low pressure water jet and soft bristle
brush to soak off caked mud or dirt.
7. Apply an approved cleaning and degreasing
agent with a brush. Obey the manufacturers
instructions.
8. Use a pressure washer to remove the soft dirt
and oil. Important: DO NOT aim the water jet
directly at oil seals or electrical and electronic
components such as ECU (Electronic Control
Unit)'s, alternator or fuel injectors. DO NOT place
the jet nozzle closer than 600mm (24 in) to
any part of the engine or after treatment system
including exhaust sensor ECU (if installed).
9. When the pressure washing is complete move
the machine away from the wash area, or
alternatively, clean away the material washed
from the machine.
10. Before working on specific areas of the engine
use a compressed air jet to dry off any moisture.
When the area is dry use a soft clean brush to
remove any sand or grit particles that remain.
11. When removing components be aware of any
dirt or debris that may be exposed. Cover any
open ports and clean away the deposits before
proceeding
Additional cleaning must be carried out prior to
working on the high pressure fuel system, refer to:
Fuel System - Clean (PIL 18-00).
