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.
Renewal of oil seals, gaskets, etc., and any
component showing obvious signs of wear or
damage is expected as a matter of course.
It is expected that components will be cleaned and
lubricated where appropriate, 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 JCB ecoMax engine is a 4 cylinder diesel engine
in which the fuel is ignited by compression ignition.
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. Refer to: PIL 15-75.
When the engine runs the crankshaft drives the
camshaft via gears. The camshaft opens and closes
the inlet and exhaust valves and via 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 high pressure fuel pump
via gears. The pump is part of the electronically
controlled common rail fuel injection system. Refer
to: PIL 18-00.
Air is drawn into the engine, via the inlet manifold
and exhaust gases exit via the exhaust manifold.
The engine uses a VGT (Variable Geometry
Turbocharger) which pressurises the air at the inlet
manifold. Refer to PIL 18-36.
A mechanical lubrication oil pump is driven by
the crankshaft via gears. The pump pressurises
and circulates oil for engine lubrication and cooling
purposes.
A drive belt driven by the crankshaft, drives a
coolant circulation pump, alternator, radiator cooling
fan and other ancillaries such as an air conditioning
compressor.

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
accordance with local regulations. Use authorised
waste disposal sites.

Operation
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:
Table 5. The Four Stroke Cycle
Stage num-
ber
Piston operation Valve operation
1 The piston is at the top of its Compression
stroke and is about to start its Power stroke.
Inlet and exhaust valves closed
2 The piston is at the bottom of its Power stroke
and is about to start its Exhaust stroke.
Inlet valves closed, exhaust valves about to
open
3 The piston is at the bottom of its Induction
stroke and is about to start its Compression
stroke.
Exhaust valves closed, inlet valves about to
close
4 The piston is at the top of its Exhaust stroke
and is about to start its Induction stroke.
Valve Operation Exhaust valves about to
close, inlet valves about to open
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.

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 connectors and
electronic components such as ECU (Electronic
Control Unit)'s, alternator or fuel injectors. DO
NOT place the jet nozzle closer than the specified
distance to any part of the engine or exhaust
system.

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

Engine Compression Test
This test is used to diagnose suspected poor
compression in one or more of the engine cylinders.
Use a dummy injector to do the test.
Several factors can influence the compression
pressure, the following conditions are assumed:
• The valve clearances have been set correctly,
refer to (PIL 15-30).
• The correct engine oil has been used, refer to
(PIL 75-03).
• The engine oil level is correct, refer to (PIL
15-21).
• The correct type of diesel fuel has been used
and the system correctly primed, refer to (PIL
75-18).
• The battery and starting circuit is fully charged
and in good condition, e.g. good earth paths,
cable connections tight etc.
When comparing the figures recorded in the
following procedures, there should be a minimum
variation of 3.5bar (50.7psi) between each cylinder. If
the variation is greater than this figure, then remove
the cylinder head, refer to (PIL 15-06) and closely
inspect the cylinder bores, pistons and piston rings
for signs of wear or damage. Repair as necessary.
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.
1. Make sure that the engine is safe to work on.
Refer to (PIL 01-03).
2. Get access to the engine.
3. Remove all four fuel injectors, refer to (PIL
18-18).
3.1. Make sure that the injectors are labelled for
correct fitting at a later stage.
4. Install the dummy injector in one of the vacant
cylinder injector bores.Refer to Figure 13.
Special Tool: Dummy Injector (Qty.: 1)
5. Install a pressure test gauge into the dummy
injector fitting.
5.1. Note: The dummy injector is drilled and
tapped 1/8-28 BSP x 8.00mm deep to
accept a standard pressure gauge fitting.
6. Remove the ESOS (Engine Shut-Off Solenoid)
to prevent accidental start of the engine. refer to
(PIL 15-86).
7. Operate the starter motor to crank the engine.
7.1. Do not crank for longer than 20 seconds.
7.2. Record the gauge reading.
8. Do the step 3 to 6 again for the remaining three
cylinders.

Engine Oil Pressure
Use the following procedures to measure the engine
oil pressure. Refer to Oil Sump (PIL 15-45) for a
full explanation of the lubricating oil circuit. Several
factors can influence the engine oil pressure, the
following conditions are assumed:
• The correct engine oil has been used, refer to
Consumable Products, Oil (PIL 75-03).
• The engine oil level is correct, refer to Oil Filter,
Check Level (PIL 15-21).
1. Make sure that the engine is safe to work on. If
the engine has been running, let it cool before
you start the service work.
2. Get access to the engine.
3. Disconnect the electrical connector to the oil
pressure switch, and remove the switch from the
oil cooler housing.
4. Install a suitable test gauge into the vacant
pressure switch port (M10 x 1.5mm thread).
Make sure that the gauge has a sealing washer
as shown.
Special Tool: Pressure Gauge (0-40 Bar) (Qty.: 1)

5. Start the engine, increase the engine revs to
the rated speed. Record the pressure gauge
reading, refer to Technical Data (PIL 15-00), for
the recommended circuit pressure.
6. Remove the pressure gauge and install the
pressure switch.
High Lubrication Oil Pressure
High oil pressure will be evident when starting in
cold conditions. Typically the pressure will be 1–
2bar (14.5–29.0psi) and higher in cold operation,
the pressure should drop when the engine reaches
normal operating temperature.
If the pressure remains high when operating
temperature is achieved, check the oil level, if this is
correct, suspect the oil pump relief valve is at fault.
Low Lubrication Oil Pressure
Several factors can be the cause of low lubricating
oil pressure:
• Low oil level - typically evident as a loss of
pressure when operating on uneven ground or
on a gradient.
• Blocked oil filter - a blocked filter will show as a
gradual loss of pressure.
• Blocked suction strainer (pick-up pipe) -
typically evident as low pressure on start up,
if the blockage frees itself in the sump, the
pressure will pick up to normal.
• Coolant in the oil - coolant in the lubricating oil
will show as a milky discolouration of the oil and
an increase in oil level. Check for damaged core
plugs, lubricating oil cooler, cylinder head and/
or gasket.
• Fuel in the oil - fuel in the oil will result in thin'
black lubricating oil, the oil will also have a
diesel fuel smell. Check the fuel injection pump
(FIP) shaft seal refer to (PIL 18-18), piston ring
wear, lift pump diaphragm damage or injector
leakage if fuel is evident in the oil.
