The manual is compiled in sections, the first three are 
numbered and contain information as follows:
1
General Information - Use the Applications Tables
at the front of the section to see which topic in the 
manual is applicable to which machine model. The 
section also includes general information such as 
torque settings and service tools.
2
Care & Safety - includes warnings, cautions and 
general procedures related to aspects of workshop 
procedures contained in the manual.
3
Routine Maintenance - includes service schedules 
and recommended lubricants for all the machine.
The remaining sections are alphabetically coded and deal 
with dismantling, overhaul etc. of specific components, for 
example:
The sections contain topics. Each topic is a self contained 
set of data about a machine SYSTEM or Device.
Some topics are only applicable to some machine models. 
Use the Applications Tables in this section to see which 
topic is applicable to which machine model.
Each topic contains data such as specifications, 
descriptions, fault finding and test procedures. Device 
topics also contain removal, replacement, dismantle and 
assemble procedures.
Some topics contain procedures and specifications for 
different variants. This happens because of market 
requirements, or when the machine specification changes 
after a period of time. Where applicable, a table in the 
introduction of each topic contains information to help you 
identify the correct specifications or procedures.
Each topic also contains a Related Topics table. This 
table lists all the topics that contain related data. For 
example a hydraulic SYSTEM contains devices such as 
valves and pumps. These devices have their own topics 
and they are listed in the SYSTEM related topics table.

may be anything between neutral circuit pressure and LSRV operating pressure.
Pink
Pressure: Pressure that is above neutral circuit pressure but lower than that denoted by Red.
Orange
Pilot: Oil pressure used in controlling a device (Pilot).
Blue
Neural: Neutral circuit pressure.
Green
Exhaust:
Light Green
Cavitation: Oil subjected to a partial vacuum due to a drop in pressure (cavitation).

Electrical Device Codes
This manual uses a code system to help you identify the 
electrical devices on the machine.
When the electrical system is designed at the factory 
codes are given to the electrical connectors on the 
electrical harnesses. The system allows the same code to 
be used for different connectors.
For this reason a different system is used in this manual.
Each main category of devices is given a code type:
Each device is given one code and the code is used 
throughout the manual. The same code is given to both the 
device and its electrical connector.
Important: The electrical schematics and the harness 
drawings in Section C are reproduced from the factory 
drawings. For this reason they retain the factory connector 
codes.

Machine Identification Plate
The machine has an identification plate mounted as 
shown. K Fig 1. ( T 1-3-3). The serial numbers of the 
machine and its major units are stamped on the plate.
Note: The machine model and build specification is 
indicated by the PIN. 
The serial number of each major unit is also stamped on 
the unit itself. If a major unit is replaced by a new one, the 
serial number on the identification plate will be wrong. 
Either stamp the new number of the unit on the 
identification plate, or simply stamp out the old number. 
This will prevent the wrong unit number being quoted when 
replacement parts are ordered.
The machine and engine serial numbers can help identify 
exactly the type of equipment you have.

Introduction
This topic contains information about torques. Torque values are given for types and sizes of bolts and hydraulic 
connectors and adapters. 
Where a torque is given as a single figure it may be varied by plus or minus 3%. Torque figures are given for fasteners 
with different surface treatments. Make sure you use the correct torque figures.
Where torques are given in topics within the other sections always use these values.

Introduction
Some external 
fasteners on JCB machines are 
manufactured using an improved type of corrosion 
resistant finish. This type of finish is called Dacromet and 
replaces the original Zinc and Yellow Plating used on 
earlier machines.
The two types of fasteners can be readily identified by 
colour and part number suffix. K Table 1. Fastener Types
( T 1-4-2).
Table 1. Fastener Types
Note: As the Dacromet fasteners have a lower torque 
setting than the Zinc and Yellow fasteners, the torque 
figures used must be relevant to the type of fastener.
Note: A Dacromet bolt should not be used in conjunction 
with a Zinc or Yellow plated nut, as this could change the 
torque characteristics of the torque setting further. For the 
same reason, a Dacromet nut should not be used with a 
Zinc or Yellow plated bolt.
Note: All bolts used on JCB machines are high tensile and 
must not be replaced by bolts of a lesser tensile 
specification.
Note: Dacromet bolts, due to their high corrosion 
resistance are used in areas where rust could occur. 
Dacromet bolts are only used for external applications. 
They are not used in applications such as gearbox or 
engine joint seams or internal applications.
Bolts and Screws
Use the following torque setting tables only where no 
torque setting is specified in the text.
Note: Dacromet fasteners are lubricated as part of the 
plating process, do not lubricate.
Torque settings are given for the following conditions: 
Condition 1
 Un-lubricated fasteners
 Zinc fasteners
 Yellow plated fasteners
Condition 2
 Zinc flake (Dacromet) fasteners
 Lubricated zinc and yellow plated fasteners
 Where there is a natural lubrication. For example, 
cast iron components
Verbus Ripp Bolts
Fig 1. 
Torque settings for these bolts are determined by the 
application. Refer to the relevant procedure for the 
required settings.

`Positional Type' Hydraulic Adaptors
Fitting Procedure
On a typical machine, some hydraulic components may 
utilise `Positional Type' SAE Hydraulic Adaptors. When 
fitting Positional Type' Hydraulic Adaptors it is important to 
adopt the following procedure. If this procedure is not 
followed correctly, damage to the `O' ring seal 4-A can 
occur resulting in oil leaks.
1
Ensure the locknut 4-B is screwed back onto the body 
of the adaptor as far as possible as shown.
2
Check the `O' ring backing washer 4-C is a tight fit on 
the adaptor. Note that the washer should not move 
freely, if the washer is slack do not use the adaptor.
3
Check the `O' ring 4-A is fitted and that it is free from 
damage or nicks. Before fitting the adaptor, smear the 
`O' ring with clean hydraulic fluid.
Note: The dimensions and shore hardness of the `O' ring 
is critical. Should it become necessary to replace the `O' 
ring, ensure that only JCB Genuine Parts are used.
4
Screw the adaptor into the port of the hydraulic 
component as far as possible, so that ALL the threads 
engage and the `O' ring is correctly seated against 
the sealing face.
5
Set the angular position of the adaptor as required, 
then secure by tightening the locknut 4-B. 
Note: When fitted correctly no more than one thread 
should be visible at 5-Z as shown.
6
Torque tighten the locknut to 81 Nm (60 lbf ft).

Rivet Nuts
TB-001_2
A 'Rivet Nut' is a one piece fastener installed 'blind' from 
one side of the machine body/framework. The rivet nut 68-
A is compressed so that a section of its shank forms an 
'upset' against the machine body/framework, leaving a 
durable thread 68-B.
Fig 68. 
Rivet nuts are fitted to various parts of the machine body 
and framework. They are used in a number of applications, 
for instance, hose clamp and hydraulic valve retention etc.
Various sized rivet nuts are available. K Table 1. 
Specifications ( T 1-5-24) to determine the size of rivet 
nut to be used for particular applications.
If for any reason a new rivet nut requires fitting, then the 
correct installation procedure must be followed. K Fitting 
Procedure ( T 1-5-25).
Note: In an emergency, and if no installation tool is 
available, it is possible to fit a rivet nut by using a nut and 
bolt the same thread diameter as the rivet nut being 
installed. However, this is not the recommended method.

Fitting Procedure
1
Drill a hole in the machine body/framework where the 
rivet nut is to be fitted. De-burr hole edges.
2
Screw the rivet nut onto the mandrel of the installation 
tool. The bottom of the mandrel should be in line with 
the bottom of the rivet nut 69-A.
Fig 69. 
3 Wind the body of the installation tool down the 
threaded mandrel until it touches the head of the rivet 
nut 70-B.
Fig 70. 
4
Insert the rivet nut (assembled to the tool) into the 
hole drilled in step 1.
5
Hold handle 71-C and at the same time draw the 
mandrel into the installation tool by turning nut 71-D. 
The rivet nut will contract in length and form an 'upset' 
(smooth bulge) seating itself against the body/
framework 71-E.
Note: The thread of the rivet nut must not be stripped, take 
care when 'upsetting' the rivet nut.
Fig 71. 
6
Remove the installation tool.

Slide Hammer Kit
TB-003
Fig 72. Typical M/c. Installation
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 72-A 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, items 72-B and 
72-C. The other end of the adaptor will have varying thread 
sizes to suit the different size of threads in the pivot pins.
Fitting Procedure
1
Prepare the pivot pin, for instance, if fitted, remove

Additives
The additives listed below are advertised as being suitable 
for bringing the lubricity levels of kerosene/low sulphur 
fuels up to those of diesel fuels. They must be used as 
specified by your fuel supplier who will understand the 
concentration level necessary.
 Elf 2S 1750. Dosage 1000-1500 ppm (0.1 - 0.15%), 
specifically for Indian Superior Kerosene (SKO) but 
may be applicable to other fuels.
 Lubrizol 539N. Dosage (on Swedish low sulphur fuel) 
250 ppm.
 Paradyne 7505 (from Infineum). Dosage 500 ppm 
(0.05%).
Note: These products are given as examples only. The 
information is derived from the manufacturers data. The 
products are not recommended or endorsed by JCB.
Service Requirements for use of B20 
Biodiesel
 The engine oil must be a grade CH4 as minimum 
specification.
 Do not leave unused B20 biodiesel in the fuel tank for 
extended periods (top up each day).
 Make sure that 1 in 5 fuel tank fills use standard diesel 
to EN590 specification, this will help to prevent 
'gumming'.
 Make sure regular oil sampling is completed (look for 
excessive unburnt fuel content, water or wear 
particles.
 Change the engine oil and filter more frequently (as a 
minimum half the recommended intervals), or as 
indicated by oil sampling.
 Change the fuel filters more frequently (as a minimum 
half the recommended intervals), or if there are 
engine performance related issues.
 Make sure the fuel is stored correctly, care must be 
taken to make sure no water enters the machine fuel 
tank (or the storage tank). Water will encourage mico-
bacterial growth.
 Make sure that the fuel pre-filter is drained daily (not 
every week as currently advised).
 Only JCB engines built after Jan. 2007 are applicable 
(i.e. engines with 07 on the end of their serial number 
and factory filled with CH4 oil) - this is not approved 
with other manufacturers.
 Use heater kits in low ambient temperature territories.
 The biodiesel must meet the following standards: 
ASTM D6751, DIN 51606, ISO 14214
Note: If necessary use a test kit to confirm the fuel 
specification. Testing kits are available (not from JCB 
currently), use the internet as a source for the kits.
Note: If performance related issues are to be reported to 
JCB Service, and the engine has been run on biodiesel, 
then the fuel system must be filled with standard diesel (at 
least 2 x tank fills) to EN590 specification and relevant stall 
speeds recorded prior to making the report.
Warranty
JCB have shown a commitment to support 
the 
environment by approving the use of biodiesel blended 
fuels.
Using a B20 blend of biodiesel requires caution and 
additional servicing of the engine is required. K Service 
Requirements for use of B20 Biodiesel ( T 1-7-4).
Failure to follow the additional recommended service 
requirements may lead to a warranty claim being declined.
Failures resulting by the incorrect use of biodiesels or 
other fuel additives are not defects of the JCB Dieselmax 
engine workmanship and therefore will not be supported 
by JCB Warranty.

Usage and Effects of Fuels
Note: The information that follows does not indicate types 
of fuel that are acceptable or unacceptable. K Acceptable 
and Unacceptable Fuels ( T 1-7-3).
1
Low Sulphur Diesel
In its basic form because of the process of reducing 
sulphur by removal of sulphur containing compounds 
(which contribute to mechanical lubrication) an 
increase in the wear rate of the fuel injection 
equipment could occur. In view of this, the major fuel 
producers add suitable lubricity improvers to enable 
the FIE to run satisfactorily, with no acceleration in 
wear rate. They must ensure that the lubricity 
improvers do not themselves create residual deposits 
that could block the fuel system e.g. filter, injectors 
etc.
In addition to the lubrication effect there can also be a 
further reduction in the aromatic content of the fuel 
which can lead to shrinking/cracking of traditionally 
nitrile rubber seals throughout the fuel injection 
equipment that has previously been exposed to 
higher sulphur level fuels. The major fuel producers 
tend to maintain the total aromatic content to an 
acceptable level (15% by volume).
2
Ultra Low Sulphur Diesel
Also known as `city diesel'. Available throughout the 
UK and some parts of Europe since March 1999. This 
fuel has a maximum sulphur content of 0.005% by 
weight and a further reduction in the natural lubricity 
and aromatic content than experienced with low 
sulphur diesel. Major oil producers will add lubrication 
improvers and also maintain the total aromatic 
content to an acceptable level.
3
Unmodified Vegetable Oils
Burned in diesel engines neat or used as an extender 
to mineral derived fuel. When these are subjected to 
heat in the fuel injection system they form sticky 
deposits that can be found inside the fuel pump and a 
hard lacquer in the injectors where exposure to even 
higher temperatures takes place.
4
Chemically Modified Vegetable Oils (FAME/VOME)
These fuels have been derived from a wide range of 
vegetable oils and animal fats, resulting in better 
stability, viscosity and cetane number than those 
produced from unmodified vegetable oils, but it is 
recognised that 
there are potential problems 
associated with the finished fuel characteristics. 
These oils are less stable than mineral oil derived 
fuels when stored and they will readily degrade 
producing fatty acids, methanol and water, none of 
which are desirable in the FIE. These effects are 
known to be accelerated when the fuel is stored in the 
presence of air and water together.
An extract `common statement' from the FIE 
manufactures specifies that "The fuel injection 
equipment manufacturers can accept no liability 
whatsoever for failure attributable to operating their 
products with fuels for which the products were not 
designed, and no warranties or representations are 
made as to the possible effects of running these 
products with such fuels".
The three most common Fame types are RME - 
Rapeseed methyl ester (preferred crop in Europe), 
SME - Soyabean methyl ester (preferred crop in 
USA). Less common FAME's can be derived from 
animal fats (e.g. modified beef extracts) and 
reclaimed cooking oils.
5
B20 Biodiesel 
Biodiesel refers to pure fuel (FAME/VOL) before it is 
blended with diesel fuel K Chemically Modified 
Vegetable Oils (FAME/VOME) ( T 1-7-6). When 
biodiesel is blended with diesel fuel it is referred to as 
B5, B20 etc., where the number indicates the 
percentage of biodiesel in the fuel, for example B5 
contains 5% biodiesel. 
Biodiesel has different characteristics than mineral 
based fuels in that it is able to mix with water and 
therefore will have a high water retention capacity - 
this could lead to seals swelling, fuel system 
corrosion and seal damage. 
Biodiesels will `cloud' at higher temperatures than 
mineral based fuels. To explain Cloud Point - the 
lowest temperature at which fluid can flow and 
performs its functions is referred to as Pour Point. 
Just prior to reaching its Pour Point the diesel fluid 
becomes `cloudy' due to crystallization of waxy 
constituents - this is know as Cloud Point. Using 
diesel at temperature below its cloud point can result

in filter clogging. To prevent this happening pre-
heating will be required. 
Using B20 biodiesel can result in unburnt fuels 
accumulating in the engine oil, ultimately this can 
affect the engine oil efficiency and lead to engine 
damage (with standard diesel any unburnt fuel 
evaporates off the lubricating oil). Biodiesels must be 
stored to exclude water absorption and oxidation. 
The natural properties of biodiesel make it a good 
medium for micro bacterial growth, these microbes 
can cause fuel system corrosion and early fuel filter 
blocking. It will be necessary to consult and seek 
advice from your fuel supplier, the effectiveness of 
conventional antibacterial additives when used in 
biodiesel is still being investigated in the fuel industry. 
A high percentage biodiesel mixture (>20%) can lead 
to fuel gelling and filter blocking in low temperature 
operation, 
it may also effect the power and 
performance of the engine.
To minimise the risk of engine damage when using a 
B20 mix, there are additional service requirements. 
K Service Requirements 
for use of B20 
Biodiesel ( T 1-7-4)
If the recommended actions are not taken there may 
be the following consequences:- low temperature 
filter clogging- 
injectors 
lacquering / sticking- 
deterioration of seals and rubber hoses- corrosion of 
metal parts in the fuel system- engine performance 
problems. These risks will be increased if the fuel has 
been poorly stored, that is deteriorated through 
oxidation and / or water absorption.
Sulphur Content
High sulphur content can cause engine wear. (High 
sulphur fuel is not normally found in North America, 
Europe or Australia.) If you have to use high sulphur fuel 
you must change the engine oil more frequently. 
K Table 3. Sulphur Content ( T 1-7-7).
Low sulphur fuels must have the appropriate fuel lubricity 
additives, these lubricity improvers must not create 
residual deposits that block the fuel system, e.g. injectors, 
filters etc. Contact your fuel Supplier.
!MCAUTION
A combination of water and sulphur will have a 
corrosive chemical effect on fuel injection equipment. 
It is essential that water is eradicated from the fuel 
system when high sulphur fuels are used.

Effects of Fuel Contaminates
The effect of dirt, water and other contaminants in diesel 
can be disastrous for injection equipment:
 Dirt - A severely damaging contaminant. Finely 
machined and mated surfaces such as delivery 
valves and distributor rotors are susceptible to the 
abrasive nature of dirt particles - increased wear will 
almost inevitably lead to greater leakage, uneven 
running and poor fuel delivery.
 Water - water can enter fuel through poor storage or 
careless handling, and will almost 
inevitably 
condense in fuel tanks. The smallest amounts of 
water can result in effects that are just as disastrous 
to the fuel injection pump as dirt, causing rapid wear, 
corrosion and in severe cases, even seizure. It is 
vitally important that water is prevented from reaching 
the fuel injection equipment. The filter/water trap must 
be drained regularly.
 Wax - Wax is precipitated from diesel when the 
ambient temperature falls below that of the fuel's 
cloud point, causing a restriction in fuel flow resulting 
in rough engine running. Special winter fuels may be 
available for engine operation at temperatures below 
0C (32F). These fuels have a lower viscosity and 
limit wax formation.

Tests carried out at the factory record the correct engine 
r.p.m. (stall speed) when under maximum load from the 
transmission and hydraulic systems. 
The figures relate to tests conducted at an ambient of 25 
0C and barometric pressure of 100 kPa (sea level). Note 
that changes in ambient temperature, pressure and 
humidity and fuel grade will affect engine power and hence 
the stall figures.
As an example, at 10,000 ft the power reduction of a 
naturally aspirated engine could be 29% and for a turbo 
engine 8%.
Note: The figures apply to `bedded-in' engines, i.e. 
engines that have done a minimum of 250 working hours, 
therefore they should not be used for pre-delivery 
inspection (PDI) checks.
All figures are recorded with the transmission oil at 60C 
(140 F) and the hydraulic oil at 55 C (131 F). Figures 
achieved should be within +/- 100 rpm from the figures 
given in the table.

Safety - Yours and Others
INT-1-3-1_3
All machinary can be hazardous. When a machine is 
correctly operated and properly maintained, it is a safe 
machine to work with. But when it is carelessly operated or 
poorly maintained it can become a danger to you (the 
operator) and others.
In this manual and on the machine you will find warning 
messages. Read and understand them. They tell you of 
potential hazards and how to avoid them. If you do not fully 
understand the warning messages, ask your employer or 
JCB distributor to explain them.
But safety is not just a matter of responding to the 
warnings. All the time you are working on or with the 
machine you must be thinking what hazards there might be 
and how to avoid them.
Do not work with the machine until you are sure that you 
can control it.
Do not start any job until you are sure that you and those 
around you will be safe.
If you are unsure of anything, about the machine or the job, 
ask someone who knows. Do not assume anything.
Remember
BE CAREFUL
BE ALERT
BE SAFE
Common Rail (SE Engine) Specific
In addition to the general safety notices and general good 
workshop practices issued in this section and throughout 
the manual, there are specific points to note when 
completing maintenance on SE engine equipment:
Diesel Fuel Quality
Important: The potential for engine damage due to the 
use of incorrect or contaminated fuel is much greater with 
common rail injection technology than with mechanical 
injection systems.
For more information about cleanliness requirements and 
fuel types refer to Section 1 - General Information.
!MCAUTION
Do not allow dirt to enter the fuel system. Before 
disconnecting any part of the fuel system, thoroughly 
clean around the connection. When a component has 
been disconnected, for example a fuel pipe, always fit 
protective caps and plugs to prevent dirt ingress.
Failure to follow these instruction will lead to dirt 
entering the fuel system. Dirt in the fuel system will 
seriously damage the fuel injection equipment and 
could be expensive to repair.

Effects of Contamination
Once inside the system, fuel circuit contaminants greatly 
effect the performance and life of the fuel injection 
equipment. For example, contaminants in the fuel pump 
will develop internal wear to cause internal leakage and 
hence lower discharges. Use of poor quality fuels and poor 
maintenance could also lead to contaminants entering the 
fuel injectors. There is a possibility of catastrophic 
equipment failure if debris should prevent the injectors 
from fully closing. The main contaminants can be classified 
as follows: These contaminations can appear during 
manufacture. assembly and operation.
 Solid Particles - sand, fibres, metallic particles, 
welding scale, sealing materials and wear particles 
etc.
 Liquid - usually water and incompatible oils and 
gases.
 Gases - Air, sulphur dioxide etc. which can create 
corrosive compounds if dissolved in the fluid.
It is critical that the machine is thoroughly cleaned prior to 
completing any maintenance work. The main filter is rated 
at 2 micron = 0.002 mm (0.0007874 in).
Listed are a few typical comparisons of micron size:
 Red Blood Cell = 8 microns (0.008 mm, 0.000315 in).
 Human Hair = 70 microns (0.07 mm, 0.00275 in).
 Grain of Salt = 100 microns (0.1 mm, 0.00394 in).
 The smallest particle visible to the naked eye is 40 
microns (0.00157 in) approximately.
Common Rail Safety Checklist
The following safety checklist is intended to help remind 
you of safety procedures and practices relating to a 
common rail SE engine.
SAFETY IS YOUR RESPONSIBILITY
 Do make sure the engine and surrounding area has 
been thoroughly cleaned prior to completing any 
maintenance tasks. Refer to Section 1, Cleanliness 
Requirements.
 Do complete all work in accordance with the Service 
Manual procedures.
 Do disconnect both the battery positive (+) and 
battery negative (-) cables prior to completing any 
welding on the machine.
 Do use the recommended grade of fuel (EN590). The 
fuel injection pump, injector or other parts of the fuel 
system can be damaged if you use a fuel or fuel 
additives not recommended by JCB. Refer to Section 
1 - Acceptable and Unacceptable Fuels.
 Do make sure all the necessary new parts are 
available before starting any maintenance work.
 Do not `crack' the injector high pressure fuel lines to 
bleed the fuel system. The system operates at 
pressures in excess of 1200 bar (17400lbs/in2).
 Do not steam clean the electronic control unit (ECU) 
or the ECU connectors.
 Do not touch the ECU connector pins, this will 
eliminate the possibility of damage caused by 
electrostatic discharge.
 Do not leave any fuel connections `open' for any 
extended period of time.
 Do not open any new parts packaging until the part is 
ready to be fitted. Unnecessary exposure will 
increase the risk of contamination.
 Do not reuse high pressure fuel pipes. Reusing the 
pipes will lead to potential fuel leaks.
 Do not attempt to remove and replace the rail 
pressure sensor or high pressure valve. It is not 
possible to refit these components without the risk of 
fuel leaks. If the valve or sensor is diagnosed as faulty 
then a new common rail assembly must be fitted.

T4-001_2
Connecting and Disconnecting
Flat face quick release couplings allow the operator to 
remove and install attachments swiftly and efficiently. 
Generally, your machine pipework will be fitted with a 
female coupling A and a male coupling B. The optional 
attachment hoses will also be fitted with a female coupling 
A and a male coupling B. K Fig 3. ( T 2-2-9).
The quick release couplings should be trouble free and 
relatively easy to connect and disconnect, provided they 
are kept clean and used correctly. The recommendations 
listed below should always apply when using flat face 
quick release couplings.
Finally, please read the correct fitting and releasing 
procedures before installing or removing any optional 
attachment fitted with quick release couplings.
Quick Release Couplings - Do's and Don'ts
 Do wipe the two faces of the coupling and make sure 
they are clean before connecting.
 Do make sure the outside sleeve (female coupling) is 
pulled back when disconnecting.
 Do connect and disconnect a new coupling two or 
three times to 'work' the PTFE seals - sometimes a 
new coupling will stick if the seals have not been 
'worked'.
 Do use a spanner on the hexagon flats of the coupling 
when fitting adaptors.
 Do use a rubber or hide hammer to disconnect a 
coupling if it sticks - sticking may occur if there is dirt 
present in the coupling.
 Don't attempt to re-connect a damaged half coupling 
- this will destroy the seals and necessitate replacing 
both half couplings.
 Don't leave the coupling where it may be run over by 
a machine or otherwise crushed - this will distort the 
coupling sleeve and prevent correct connection and 
disconnection.
 Don't clamp on the smooth diameter of the coupling 
when fitting adaptors - always use the hexagon.
 Don't try to turn the sleeve (female coupling) when the 
coupling has been disconnected - the locking ball will 
wedge underneath the sleeve and destroy the 
coupling.
 Don't damage the faces of the couplings - this can 
prevent connection and disconnection, or damage 
seals and cause leakage.
 Don't try to dismantle the couplings - they are non 
serviceable parts. If a coupling is damaged it should 
be replaced with a new one.
!MWARNING
Hydraulic fluid at pressure can injure you. Make the 
machine safe before connecting or disconnecting 
quick release couplings; stop the engine and then 
operate the attachment control a few times to vent 
residual hydraulic pressure in the attachment hoses.
2-4-1-11
!MWARNING
The external surfaces of the couplings must be clean 
before connecting or disconnecting. Ingress of dirt 
will cause fluid leaks and difficulty in connecting or 
disconnecting. You could be killed or seriously injured 
by faulty Quick Release Couplings.
2-4-1-15
Before connecting or removing any hydraulic hose, 
residual hydraulic pressure trapped in the service hose line 
must be vented. Make sure the hose service line has been 
vented before connecting or removing hoses.

Hydraulic Contamination
TE-002_2
Hydraulic Fluid Quality
Construction machinery uses a large volume of fluid in the 
hydraulic system for power transmission, equipment 
lubrication, rust prevention and sealing. According to a 
survey conducted by a pump manufacturer, seventy per 
cent of the causes of problems in hydraulic equipment 
were attributable to inadequate maintenance of the quality 
of the hydraulic fluid. Therefore, it is obvious that control of 
the quality of the hydraulic fluid helps prevent hydraulic 
equipment problems and greatly improves safety and 
reliability. Furthermore from an economic angle it extends 
the life of the hydraulic fluid if quality is maintained.
Effects of Contamination
Once inside the system, hydraulic circuit contaminants 
greatly effect the performance and life of hydraulic 
equipment. For example, contaminants in a hydraulic 
pump develop internal wear to cause internal leakage and 
hence lower discharges. Wear particles generated will 
circulate with the hydraulic fluid to cause further 
deterioration in the performance of this and other 
equipment. Contaminants also enter principal sliding 
sections of the equipment causing temporary malfunction, 
scuffing, sticking and leakage and can lead to major 
problems.The main contaminants can be classified as 
follows:
1
Solid Particles - sand, fibres, metallic particles, 
welding scale, sealing materials and wear particles 
etc.
2
Liquid - usually water and incompatible oils and 
greases.
3
Gases - Air, sulphur dioxide etc. which can create 
corrosive compounds if dissolved in the fluid.
These contaminants can appear during manufacture, 
assembly and operation.
Cleaning Operation
The purpose of cleaning oil is to remove contaminants of 
all types and sludge by filtering hydraulic fluid through a 
cleaning unit. K Fig 4. ( T 2-2-10). General Bulletin 011 
also refers.
Procedure
Connect the cleaning unit in place of the hydraulic filter. 
K Fig 4. ( T 2-2-10). Run the system for sufficient time to 
pump all the hydraulic fluid through the unit. Disconnect 
the cleaning unit and reconnect the filter. Top up the 
system with clean hydraulic fluid as required.

Contaminant Standards
Dirt that damages your system is in many cases too small 
to be seen with the eye. The particle size is measured in 
microns.
1 micron = 0.001 mm (0.0000394 in).
Listed below are a few typical comparisons:
 Red Blood Cell = 8 microns (0.008 mm, 0.000315 in)
 Human Hair = 70 microns (0.07 mm, 0.00275 in)
 Grain of Salt = 100 microns (0.1 mm, 0.00394 in)
Smallest particle visible to the naked eye is 40 microns 
(0.00157) approximately.
Standards will often be quoted to ISO (International 
Standards Organisation) for which literature can be 
obtained.
Filters
The filter assembly fitted to all product ranges is designed 
to filter all the contamination that is generated through use 
to the required level of cleanliness. The filter must be 
serviced to the requirements of the machine Service 
Schedules.
To ensure optimum performance and reliability it is 
important that the machines hydraulic system is serviced 
periodically 
in accordance with the manufacturers 
requirements.

precautions must be taken if the engine is to be 
washed using a high pressure system.
Ensure that the alternator, starter motor and any other 
electrical components are shielded and not directly 
cleaned by the high pressure cleaning system.
ENG-3-3
Important: Do not aim the water jet directly at bearings, oil 
seals or electrical and electronic components such as the 
engine electronic control unit (ECU), alternator or fuel 
injectors.
Use a low pressure water jet and brush to soak off caked 
mud or dirt.
Use a pressure washer to remove soft dirt and oil.
Note: The machine must always be greased after 
pressure washing or steam cleaning.
Original Components
Always Install new oil seals, gaskets, etc. 
Components showing obvious signs of wear or damage 
should be replaced with new ones. 
Before re-installing original components do the following:
 Clean components using the applicable cleaning 
materials.
 Inspect components for signs of excessive wear or 
defects.
 Check the component specifications such as wear 
limits where applicable.
New Components
Ensure that the correct new components are installed. Do 
not substitute components from another machine. 
Components may look the same but may not be 
interchangeable. Refer to the JCB parts systems.

Battery Charging System Precautions
Obey the procedures below to prevent damage to the 
alternator and battery.
1
Ensure that 
the battery negative terminal 
is 
connected to the earthing cable.
2
Never make or break connections to the battery or 
alternator, or any part of the charging circuit whilst the 
engine is running. Disregarding this instruction will 
result in damage to the regulator or rectifying diodes.
3 Main output cables are 'live' even when the engine is 
not running. Take care not to earth connectors in the 
moulded plug if it is removed from the alternator.
4 When arc welding on the machine, protect the 
alternator by removing the moulded plug (or if 
separate output cables fitted, remove the cables).
5
If slave starting is necessary, connect the second 
battery in parallel without disconnecting the vehicle 
battery from the charging circuit. The slave battery 
may then be safely removed after a start has been 
obtained. Take care to connect batteries positive to 
positive, negative to negative.

Hydraulic Rams
Installation
1
Precautions when installing the ram on the machine.
a When installing and removing from the machine, 
suspend the ram safely.
b Suspending the ram by the piping is not only 
dangerous, but can also cause damage to the 
cylinder.
c Secure the piston rod with a band. It is very 
dangerous if the rod extends unexpectedly. Also, 
the rod can be damaged and become unusable.
2 Welding after installing the ram may result in damage.
a
If electric welding is done even at a point away 
from the ram, there may be sparking inside the 
ram and it will become necessary to replace the 
ram with a new one.
3 When painting the machine, mask the ram.
a
If paint adheres to the rod surface or to the wiper 
ring and the ram is operated, the wiper ring will not 
function properly and foreign matter and paint can 
easily enter the ram. This will cause damage to 
the seals, drastically shortening the life of the ram.
4
Install the ram only when it is clean.
Caution During Use
1
Use only under designated conditions.
a
If hydraulic oil other than the designated oil is 
used, the seals quickly degenerate and become 
damaged. If the relief valve is set at a value higher 
than specified, it may cause ram damage and is 
dangerous.
b
In high temperature environments (approx. 90C 
and above) or low temperature environments 
(below -20C), seals quickly become damaged. 
Special seal materials are necessary so check to 
see if the ram that you are using is suitable or not.
c The number one cause of ram oil leakage is rod 
damage. Be careful not to damage the rod.
2 Warm up sufficiently before beginning work.
a
In cold conditions the rod seals may be frozen, so 
if the ram is operated at maximum pressure and 
maximum speed, the seals will be damaged.
b There is a large amount of air in a new ram or one 
which has been left for a long time, so the ram will 
not operate smoothly. Also, if pressure is applied 
suddenly without bleeding 
the air, high 
temperatures will be generated due to adiabatic 
compression and the seals may burn.
c Before beginning work, always move the ram at 
full stroke with no load and expel air from the 
cylinder.
3 When stopping or storing, do it at a safe and fixed 
position.
a The installed ram cannot maintain the same 
position for a long period of time, because the oil 
inside the ram may leak and the hydraulic oil 
volume decreases as it cools. Stop or store the 
machine in a safe and fixed position.
Maintenance, Inspection Points
1
Carry out daily maintenance and inspection.
a The key point for correct long-term ram function is 
daily maintenance and inspection. Carry out 
maintenance and inspection so that the ram 
functions fully at all times. Always remove any 
mud, water, dust or oil film adhering to the rod and 
keep it in normal condition. However, when 
cleaning the wiper ring and seals, do not get them 
wet with water but wipe clean with a rag. To 
prevent rust forming during storage, the amount of 
exposed ram piston rod should be kept to a 
minimum. If leaving for more than one week, 
apply a light coating of suitable grease or 
petroleum jelly to the exposed part of the ram 
piston rod.
2
Use genuine JCB parts when replacing parts.

a
If parts other than genuine JCB parts are used, 
the desired results may not be obtained. Use only 
genuine JCB parts.
3
Caution during dismantling and reassembly.
a Dismantling the ram while it is still installed on the 
machine can be dangerous as unexpected 
movements of the machine can occur. Remove 
the ram from the machine and then dismantle.
b
If reassembled with dirty hands, foreign matter 
can enter the ram causing a shorter life span and 
also the other hydraulic equipment may be 
damaged. Reassemble in a clean state.
c Follow the instructions in the diagrams regarding 
torque tightening for screwed parts. If the torque is 
too high or too low, it can cause damage.
