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

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

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.

clean engine oil.
5. Use suitable lifting equipment (if the crankshaft
is lifted manually, two people will be required), to
carefully lower the crankshaft into the crankcase.
DO NOT rotate the crankshaft, the bearing shells
can become dislodged, refer to step 4.
6. Install the thrust washers as follows:

6.2. Make sure that they are installed in the
correct positions, with the two slots facing
outwards from the bearing saddle.
6.3. If necessary, push the crankshaft forward
and then backwards to obtain clearance to
install the thrust washers.
6.4. DO NOT rotate the crankshaft, the bearing
shells can become dislodged, refer to step

Introduction
(For: JCB Tier 2/3 Elec Engine 4 Cyl, JCB
Tier 2/3 Mech Engine 4 Cyl)
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.
