Operator's Manual. If you do not understand
anything, ask your employer or JCB dealer to
explain it.
SERVICE MANUAL Do not operate the machine without an Operator's
Manual, or if there is anything on the machine you
do not understand.
Treat the Operator's Manual as part of the machine.
Keep it clean and in good condition. Replace the
Operator's Manual immediately if it is lost, damaged
or becomes unreadable.

Introduction .................................................... 06-19 Pivot pins are a short shaft or pin that supports
Remove and Install ....................................... 06-20 something that turns. Pivot pins are installed in
numerous positions on the machine. There is usually
a greasing point associated with the pivot pin.
Make sure that the pivot points are greased at
regular intervals. Refer to the Machine Maintenance
Schedules. Refer to (PIL 78-24).
Slide Hammer Kit
The slide hammer kit is used to remove pivot pins that
must be extracted, i.e. cannot be 'knocked through'.
The purpose of this description is to explain how the
kit and the various components are used to remove
the pivot pins.
The adaptors that form part of the kit have a screwed
thread at each end. One of the threads will always
be M20 size, this is to accommodate the end stops.
The other end of the adaptor will have varying thread
sizes to suit the different size of threads in the pivot
pins.

Introduction
In addition to the operator check the extinguisher
must be serviced every 12 months by a suitably
qualified person.
1. Examine the fire extinguisher for damage and
leaks.
2. Make sure the fire extinguisher is correctly
attached.
3. Make sure that the gauge indicates that the
extinguisher is charged i.e. the needle is in the
green segment
3.1. If the needle is in or very near the red
segment at either end of the gauge, the
extinguisher must be serviced or replaced.
4. Make sure the safety pin is correctly installed.

the relevant safety precautions, Health and Safety
(PIL 09-09).
1. Always wear safety glasses during removal and
replacement.
2. Use protective gloves - heavy duty leather
gauntlet type gloves when cutting out the broken
glass, non-slip type gloves when handling/
moving panes of glass, surgical type gloves
when you use the polyurethane adhesives.
3. Wear protective overalls.
4. Do not smoke - the activators and primers used
in the procedures are highly flammable.
5. Do not attempt to handle or move panes of glass
unless you are using glass lifters.
Several special tools are required to successfully
complete the removal and replacement procedures.
Reference is made to the tools in the procedures.
The majority of these tools can be obtained locally
and the remainder from JCB Service.
The work must only be carried out in a dry, frost free
environment. A protective canopy may be required
or the machine/frame must be moved to a sheltered
area.
In damp or wet conditions, hinged doors and window
frames can be removed from the machine and taken
to a more suitable (dry) environment.
Glass should not be replaced at temperatures below
5°C (41.0°F).

1. Make sure that you disconnect and connect the
applicable harness connectors.
2. Do not force the panels away from the operator
station frame.
3. Make sure that you remove all the fasteners.
4. If the operator station panel is replaced with a
new one, move the applicable components to the
new trim panels.

Introduction .................................................... 15-17 The crankcase is the main body of the engine,
Technical Data ............................................... 15-18 to which other engine parts are attached. The
Check (Condition) .......................................... 15-18 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.
Wet and replaceable cylinder liners are supported
at the middle of the crankcase, which reduces
vibrations and directs the coolant circulation mainly
to the upper part of the liners.
The seal between the lower part of the cylinder liner
and the crankcase is achieved by O-rings (x3). The
O-rings are installed in grooves in the liners. The
upper part is sealed by the cylinder head gasket.
The camshaft is located in the crankcase. There
are separate bearing sleeves in all camshaft bearing
locations and the drilling for the camshaft rear end is
covered with a plug.
There are spaces on both sides of the rear main
bearing for guide bearing shims/crankshaft thrust
bearings.

Component Identification ............................... 15-51
Operation ....................................................... 15-52 The relationship between the rotation of the camshaft
and the rotation of the crankshaft is of critical
Check (Condition) .......................................... 15-54 importance. Since the valves control the flow of the
Remove and Install ....................................... 15-54 air/fuel mixture intake and exhaust gases, they must
be opened and closed at the appropriate time during
the stroke of the piston. For this reason, the camshaft
is connected to the crankshaft directly, via a gear
mechanism.
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, refer to Engine-Operation
(PIL 09-00).

The connecting rods are divided into weight classes
with intervals of 0.02kg. The weight class is stamped
on the side face of the connecting rod. Refer to
