Introduction
9803/3400 Issue 1
General
This Service Manual is designed for the benefit of JCB Distributor Service Engineers who are receiving or have received, train-
ing by JCB Technical Training Department.
These personnel have a sound knowledge of safe workshop practices, safety procedures, and general techniques associated
with the maintenance and repair of hydraulic earthmoving equipment.
The replacement of oil seals, gaskets and any other components showing obvious signs of wear or damage is expected as a
matter of course. Components should be cleaned and lubricated where appropriate, and any open hose or pipe connection must
be blanked off to prevent the loss of hydraulic fluid or allow an ingress of dirt. Finally, please remember SAFETY COMES FIRST!
Service Manual Layout
This Service manual is compiled in sections, the first three are numbered and contain information as follows:
1 General Information
2 Care and Safety
3 Routine maintenance
The remaining sections are alphabetically coded and deal with the overhaul and inspection of specific components, for exam-
ple:
A Attachments
B Body and Framework ....etc.
The page numbering in each alphabetically coded section is not continuous. This allows for the insertion of new information in
later issues of this Service Manual.
Section contents, technical data, circuit descriptions, operation descriptions etc are inserted, where necessary, at the beginning
of each alphabetically coded section.
Read the section contents to locate machine types, machine type identification is not listed on individual pages.
All sections are listed on the front cover; tabbed divider cards align directly with each individual section for quick reference.
Where a torque setting is given as a single figure it may be varied by plus or minus 3%. Torque figures indicated are for dry
threads. Torque figures for lubricated threads can be reduced by one third.
“Left Hand” and “Right Hand” are as viewed from the rear of the machine facing forwards.
This Service Manual covers the following machine type:

Vehicle Identification Number (VIN)
The Product Identification Number (PIN), transmission pump
serial number and engine serial number positively identify the
type of Teletruk that you have. These numbers are stamped
on the machine VIN plate as shown in the following Figure.
A typical VIN is a 17 digit number as follows:
SLP TLT25 V E 0788001
SLP Manufacturer (JCB)
TLT25 Machine Model (Teletruk)
V Year (1997)
E Country (England)
0788001 (PIN)
Unit Identification
To confirm the identity of your machine, check the VIN plate
details against the serial numbers of each component.
Typical Engine Identification Number
This applies to the diesel engines only.

Introduction - Zinc Plated Fasteners and Dacromet Fasteners
JCB Teletruks are assembled 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 as follows:
Fastener Type Colour Part Number
Zinc and Yellow Golden finish ‘Z’ (e.g. 1315/3712Z)
Dacromet Mottled silver finish ‘D’ (e.g. 1315/3712D)
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 fasteners.
Note: A Dacromet bolt should not be used in conjunction with a Zinc and Yellow plated nut, as this could change the torque
characteristics of the torque settings further. For the same reason, a Dacromet nut should not be used in conjunction with a
Zinc and Yellow plated bolt.
Use only where no torque setting is specified in the text. Values are for dry threads and may be within three per cent of the
figures stated. For lubricated threads the values should be REDUCED by one third.

Lubricants - Health and Safety
Hygiene
JCB lubricants are not a health risk when used properly for
their intended purposes.
However, excessive or prolonged skin contact can remove
the natural fats from your skin, causing dryness and
irritation.
Low viscosity oils are more likely to do this, therefore
particular care is necessary in handling used oils which can
be diluted with fuel contamination.
Whenever you are handling oil products you should maintain
good standards of care and personal and plant hygiene. For
details of these precautions we advise you to read the
relevant publications issued by your local health authority,
and note the following:
Storage
Always keep lubricants out of the reach of children.
Never store lubricants in open or unlabelled containers.
Waste Disposal
All waste products should be disposed of in accordance with
all the relevant regulations.
The collection and disposal of used engine oil should be in
accordance with any local regulations. Never pour used
engine oil into sewers, drains or on the ground.
Handling
New Oil
There are no special precautions needed for the handling or
use of new oil, beside normal care and hygiene practices.
Used Oil
Used engine crankcase lubricants contain harmful
contaminants. In laboratory tests it was shown that used
engine oils can cause skin cancer.
Here are precautions to protect your health when handling
used engine oil:
1 Avoid prolonged, excessive or repeated skin contact
with used engine oils.
2 Apply a barrier cream to the skin before handling used
engine oil.
3 Note the following when removing engine oil from skin:
a Wash your skin thoroughly with soap and water.
b Using a nail brush will help.
c Use special hand cleansers to help clean dirty
hands.
d Never use petrol, diesel fuel or paraffin for washing.
e Avoid skin contact with oil soaked clothing.
f Don't keep oily rags in pockets.
g Wash dirty clothing before re-use.
h Throw away oil-soaked shoes.
First Aid - Oil
Swallowing.
If oil is swallowed you should not induce vomiting. Get
medical advice.
Skin
In the case of excessive skin contact you should wash with
soap and water.
Eyes
In the case of eye contact, flush with water for 15 minutes. If
irritation persists, get medical attention.
Spillage
Absorb on sand or a locally approved brand of absorbent
granules. Scrape up and remove to a chemical disposal
area.
Fires
Extinguish with carbon dioxide, dry chemical or foam.
Firefighters should use self contained breathing apparatus.
!! WARNING
Do not use water to put out an oil fire. This will only
spread it because oil floats on water.
Extinguish oil and lubricant fires with carbon dioxide, dry
chemical or foam. Fire fighters should use self contained
breathing apparatus.

The Teletruk must be greased regularly to keep it working
efficiently. Regular greasing will also increase the machine’s
working life.
Grease of the correct specification should be applied with a
grease gun (except for the boom pads runway, which should
have Waxoyl applied along its length). Stop greasing when
fresh grease appears at the joint. Use JCB High Pressure
(HP) grease for improved machine reliability.
Location of Greasing Points
For the purposes of greasing, the Teletruk is split into five
separate sections:
A Carriage.
B Boom.
C Rear steer axle.
D Sideshift.
E Boom pads runway.
Note: Refer to the following figures for the location of
each individual grease point.
Greasing Procedure
1 Park the Teletruk on firm level ground.
!! WARNING
After raising or extending the boom, ensure that chocks
or suitable supports are used to prevent it from falling.

deg C deg F deg C deg F
50% -33 -27 -45 -49
Never use less than 45% antifreeze solution otherwise there
will not be enough corrosion protection.
Never use more than 50% antifreeze solution otherwise the
cooling system may be damaged.
Leave the antifreeze in all the year round as it gives protection
against corrosion.
Check the strength of antifreeze solution at least once a year,
preferably at the start of the cold period. Always renew the
antifreeze every two years.
A 50% antifreeze solution should be used even if frost
protection is not needed. This gives protection against
corrosion and raises the coolant's boiling point.

Fuel System - Diesel 10 - 110 - 1
*Types of Fuel
Use good quality diesel fuel to get the correct power and
performance from your engine. The recommended fuel
specification for JCB engines is given below.
Cetane Number: 45 (minimum)
Viscosity: 2.5/4.5 Centistokes at 40 °C (104 °F)
Density: 0.835/0.855 kg/litre
(0.872/0.904 lb/pint)
Sulphur: 0.5% of mass (maximum)
Distillation: 85% at 350 °C (662 °F)
Cetane Number
Indicates ignition performance. Fuel with a low cetane
number can cause cold start problems and affect
combustion.
Viscosity
Is the resistance to flow. If this is outside limits, the engine
performance can be affected.
Density
Lower density will reduce engine power. Higher density will
increase both engine power and exhaust smoke.
Sulphur
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 sulfur fuel you must also
use a highly alkaline engine lubricating oil; or change the
normal oil more frequently.
Distillation
This indicates the mixture of different hydrocarbons in the
fuel. A high ratio of lightweight hydrocarbons can affect the
combustion characteristics.
Low Temperature Fuels
Special winter fuels may be available for engine operation at
temperatures below 0 °C (32 °F). These fuels have a lower
viscosity. They also limit wax formation in the fuel at low
temperatures. (Wax forming in the fuel can stop the fuel
flowing through the filter).
Flow improvers may also be available. These can be added
to the fuel to reduce wax formation.
Petrol
!! WARNING
Do not use petrol in this engine. Do not mix petrol with
the diesel fuel. In storage tanks the petrol could rise to
the top and form flammable vapors.
INT-3-1-6
Filling the Tank
!! WARNING
Diesel fuel is flammable; keep naked flames away from
the machine. Do not smoke while refueling the machine
or working on the engine. Do not refuel with the engine
running. There could be a fire and injury if you do not
follow these precautions.
INT-3-2-2
At the end of every working day, fill the tank through the filler
A with the correct type of fuel.
This will prevent condensation from developing in the fuel
tank overnight.

6 Open the fuel injection pump vent valve A.
7 Operate the priming pump C or priming pump lever B
slowly until fuel with no air flows freely from the valve, then
close the valve.
Notice: If no fuel is moved when the priming lever B is
operated then the pump diaphragm may have rested in a
maximum lift position. To move the diaphragm, use the
starter key to turn the engine slightly, then try the priming
lever again.
8 Slacken the bleed plug on the sedimentor bowl and again
operate the lift pump priming lever until fuel with no air
flows freely from the plug, then tighten the plug.
9 Remove the E.S.O.S. fuse to prevent the engine from
starting.
!! 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.
