T SERIES ENGINES OPERATORS' HANDBOOK
INTRODUCTION
This handbook explains the operation
and routine maintenance of Lister
Petter T series (TR) air cooled diesel
engines.
If your engine is part of a Lister Petter
generating set, there is a separate
operators' handbook for the genset,
to explain such features as the control
module.
ENGINE IDENTIFICATION
To identify which model of Lister Petter
T-Series diesel engine you are using
refer to the engine serial number, which
is stamped on a plate attached to the
engine. It identies the type and build
of the engine (see below) to enable
the correct maintenance procedures
to be carried out. Here is asample

When following the instructions in this
handbook you will need to be familiar
with the parts labelled. (See also table
below.)
USING THIS HANDBOOK
Operating or servicing a diesel engine
is potentially dangerous. You must not
attempt it unless you have the necessary
knowledge and experience.
Read each section thoroughly
and carefully, taking note of the all
information and instructions given. This
is for your safety and to ensure the
correct maintenance of your engine.
For specific aspects of operation
and maintenance, use the table of
contents or the index to nd the section
you need. Where instructions are
numbered in sequence, they must be
followed in that order. This applies in
particular to maintenance and repair
procedures (Sections 5 and 6).
In cases of difculty, or to obtain spare
parts, please consult your local Lister
Petter distributor or dealer.
RUNNING-IN
To assist running-in all engines are
despatched with an initial ll lubricating
oil which must be changed after 100
hours. Your engine does not require
gradual light-load running-in. Extended
light-load running should be avoided,
as this could damage the cylinder bore
and allow lubricating oil to enter the
exhaust system.

T SERIES ENGINES OPERATORS' HANDBOOK
Carefully read and follow all safety
information and instructions in this
manual.
Observe the safety and informative
symbols on your engine and
equipment.
Emergency Precautions
• Be prepared with suitable equipment
and knowledge in case a re starts.
• Identify a location from which calls
to the emergency services can be
made if necessary.
• Ensure a third party knows where
you are working and when you leave
the working area.
General Precautions
• Ensure the engine is securely
mounted.
• Ensure that there is a generous
supply of cooling and combustion air
available.
• Keep the engine and surrounding
area clean.
• Some accessories may require
guards which must be supplied and
tted by the purchaser. Keep all safety
guards in position.
• Do not make any unauthorised
modications as these may affect the
safe operation of the engine and put
the operator at risk.
1.2 PERSONAL SAFETY
• Wear personal protective clothing
and safety equipment appropriate to
the work being done.
• Keep clear of moving parts at all
times.
WARNING
KEEP THE BODY AND CLOTHING
CLEAR OF MOVING OR HOT PARTS
ATALLTIMES. CONTACTOFMOVING
PARTS WITH UNPROTECTED SKIN
CAN CAUSE SEVERE BURNS.
ENTANGLEMENT WITH ROTATING
EQUIPMENT CAN CAUSE SERIOUS
INJURY OR DEATH.
• Tie long hair close to your head.
• Wear close-tting clothing.
• Do not wear a necktie, scarf, loose
clothing or necklace when working
close to a running engine.
• Where possible, remove rings and
other jewellery to prevent entanglement
in moving parts. These items could also
cause a short circuit if any part of the
electrical system is being worked on.
WARNING
Protect yourself against prolonged
exposure to loud noise. Failure to do
so can cause impairment, or loss,
of hearing.
• Wear suitable ear protection against
loud noise.
• To avoid loss of concentration, do
not use music or radio headphones
while operating an engine.
• When undertaking maintenance, do
not work under any plant that is held
only by overhead lifting equipment.
• Where appropriate, make sure that
guards are properly tted.
1.3 PRECAUTIONS WITH
CHEMICALS
Protect yourself from exposure to
hazardous chemicals at all times,
as this can cause serious injury.
Potentially hazardous chemicals
include lubricants, fuel, battery acid,

10
T SERIES ENGINES OPERATORS' HANDBOOK
paint and adhesives.
Manufacturers' safety data sheets
will provide specific details of the
physical and health hazards, safety
and emergency procedures and
any necessary personal protection
equipment required while working with
hazardous materials.
• Handle uids with care at all times.
• Rectify any fuel or oil leak as soon
as is practicable and clean up any
spillages when they occur.
• Remove any build-up of grease, oil
or debris.
• If any uid comes into contact with
the skin, clean off immediately (in the
case of lubricating oil, clean off as soon
as is practicable).
Fuel and High Pressure Fluids
• Store fuel and other flammable
liquids away from re hazards.
• Always stop the engine before
refuelling.
• Do not overll the fuel tank.
• When working with fuel do not
smoke or work near to heaters or other
re hazards.
• High pressure uids are extremely
hazardous. Never allow any part of the
body to come into contact with high-
pressure fuel oil, compressed air or
hydraulic oil, for example when testing
fuel injection equipment.
WARNING
D o n o t e x p o s e p r e s s u r i s e d
containers to heat, and do not
incinerate or puncture them.
WARNING
NEVER TOUCH OR INGEST HIGH-
PRES SURE FLUIDS SUCH AS
HYDRAULIC OIL, COMPRESSEDAIR
OR FUEL OIL. THIS COULD LEAD
TO SERIOUS INJURY, OR DEATH.
1.4 FUEL SYSTEM
PRECAUTIONS
WARNING
NEVERALLOWANY UNPROTECTED
SKIN TO COME INTO CONTACT WITH
THE INJECTOR SPRAY AS FUEL
MAY ENTER THE BLOODSTREAM
WITH FATAL RESULTS.
WARNING
Never make unauthorised
adjustments to the fuel injection
pumps. This could be dangerous
and invalidates warranty claims.
• When priming or checking the fuel
injection pump timing, care must be
taken to wipe any spilled fuel from the
outside of the engine.
• Always t a new joint when a union
has been disturbed.
• Special care must be taken to see
that there is no leakage from the joints
of the fuel pipe connection to the pump.
• When tightening or loosening fuel
injection pump delivery connections
use two spanners to prevent unsealing
of fuel pump delivery valve holders.
• When retting the fuel pipe from the
pump to the injector, the connection to
the injector must be tightened before
the connection to the fuel pump. This
procedure will ensure that there is no
leakage from these joints.
• It is most important that all fuel
joints are tight and leak-proof.
• Always ll the fuel tank through
a ne strainer. It is best to do this at
the end of the engine work period so
that any sediment stirred up has time
to settle before the engine is used
again, and the risk of condensation
contaminating the fuel is minimised. If
using a can, avoid tipping out the last
few drops.

11
T SERIES ENGINES OPERATORS' HANDBOOK
• Funnels are very difcult to keep
clean in dusty conditions. Wash them
before and after use and wrap them up
when not required, or ll the tank direct
from a small-mouthed screw-capped
can.
• The fuel injection equipment is
manufactured to very accurate limits
and the smallest particle of dirt will
destroy its efciency.
CAUTION
Keep the fuel free from water and
contaminants.
1.5 PRECAUTIONS WITH
FILTERS AND ELEMENTS
• Used lters and elements contain
some of the ltered liquid and should be
handled and disposed of with care.
• After handling new or used elements,
wash your hands thoroughly.
WARNING
Do not allow fuel or new or used
lubricating oil to come into contact
with unprotected skin. It is dangerous
and could cause skin irritation.
WARNING
Take careful precautions with lters
and elements. The materials used in
the manufacture and treatment of
some types may cause irritation or
discomfort if they come into contact
with the eyes or mouth, and they
may give off toxic gases if burnt.
1.6 PRECAUTIONS WITH OIL
SEALS
Some engines may be tted with seals
or 'O' rings manufactured from Viton
or a similar material. When these
substances are exposed to abnormally
high temperatures, in excess of 400°C
(752°F), an extremely corrosive acid is
produced.
WARNING
IF AN OIL SEAL CONTAINING
VITON (OR SIMILAR MATERIAL)
DEGENERATES, IT PRODUCES
AN EXTREMELY CORROSIVE ACID
THAT CANNOT BE REMOVED FROM
THE SKIN. IF YOU SEE SIGNS
OF DECOMPOSITION, OR ARE
IN DOUBT, WEAR DISPOSABLE
HEAVY DUTY GLOVES.
• If in any doubt about an oil seal,
always wear disposable heavy-duty
gloves.
1.7 PRECAUTIONS WITH
BATTERIES
Batteries contain hazardous sulphuric
acid. Great care therefore needs to be
taken when using them.
• Do not smoke near batteries and
keep sparks and ames away from
them. Do not work near to heaters or
other re hazards.
• Switch off the battery charger
before connecting or disconnecting
the charger leads. Disconnect the
battery negative (earth) lead rst and
reconnect last.
• Keep the top of the battery well
ventilated during charging.
• Never ash connections.
• Never use a damaged battery.
• Before charging the battery warm
it to around 16°C (60°F).
WARNING
Never attempt to charge a frozen
battery; it may explode.

12
T SERIES ENGINES OPERATORS' HANDBOOK
WARNING
Take especial care with batteries,
which contain highly corrosive
sulphuric acid which is poisonous,
will burn skin and clothing, and will
cause permanent damage including
blindness if splashed into the eyes. If
acid accidentally comes into contact
with skin, eyes or clothes, ush it
away with copious amounts of fresh
water and seek medical aid.
1.8 PRECAUTIONS WITH
ELECTRICAL SYSTEMS
• Ensure that the battery is of sufcient
capacity to start the engine down to its
minimum operating temperature, taking
into account any drag that may be
imposed on the engine by the type of
transmission that is attached to it.
• Ensure that the battery and all
engine wiring cables are of sufcient
size to carry the currents required.
• Check that the engine-mounted
alternator is of sufcient output to cope
with the total electrical load required by
the machine to which it is tted.
Wiring
Ensure that the engine wiring cables are:
• Bound together in a loom and
adequately supported.
• Routed to avoid any hot surfaces,
particularly the exhaust system.
• Not in contact with any rough
surfaces or sharp corners so as to
avoid any possibility of chang.
Charge Winding Precautions
• Never connect a battery into the
system without checking that the
voltage and polarity are correct.
• Always ensure cables are tted to
their correct terminals.
• Never flash any connection to
check the current ow.
• Ne v e r e x p e r i m e n t w i t h a n y
adjustments or repairs to the system.
CAUTION
Ensure that the battery is correctly
connected. Failure to do so could
cause short circuit or reversal of
polarity, destroying diodes and
transistors.
• Never remove any electrical cable
whilethe batteryis connectedinthe circuit.
• Never disconnect the battery
unless the engine has stopped and all
switches are in the off position.
• Always disconnect the battery and
charge windings before commencing
any electric welding when a pole strap
is directly or indirectly connected to the
engine.
1.9 WASTE DISPOSAL
PRECAUTIONS
• Extreme care must be taken
to ensure that waste oil, fuel, filter
elements, battery electrolyte, solvents
or other toxic wastes are disposed of
in accordance with local regulations to
prevent contamination.
WARNING
To avoid contamination and personal
injury, never dispose of toxic or
other waste except in accordance
with ofcial regulations.
1.10 PRECAUTIONS BEFORE
STARTING
WARNING

potentially dangerous. Do not
attempt to do so unless you have
been properly trained.

13
T SERIES ENGINES OPERATORS' HANDBOOK
• Ensure that the engine is free to
turn without obstruction.
• Check that the lubricating oil level
is correct. The oil sump must be lled
to the ‘full’ mark on the dipstick; do not
overll.
• Check that the fuel supply is
adequate and the system is primed.
• Ensure that the battery is connected,
fully charged and serviceable.
• Where possible, disengage the
driven equipment while starting.
1.11 LIFTING PRECAUTIONS
A lifting eye is tted to the top of your
T Series engine. The following points
must be considered before attempting
to lift the engine.
• Ensure any lifting equipment to be
used has the correct capacity to lift the
engine.
• Ensure that the lifting equipment
is designed to give a vertical lift from
directly above the engine lifting eye.
• Check that the engine lifting eye is
not damaged and that it is secure.
• The engine lifting eye is suitable
for lifting the engine and accessory
assemblies originally tted by Lister
Petter.
WARNING
Engine lifting eyes must not be used
to lift the complete plant.
WARNING
DO NOT WORK UNDER ANY PLANT
THAT IS ONLY HELD BY OVERHEAD
LIFTING EQUIPMENT.
1.12 PRECAUTIONS BEFORE
MAINTENANCE
• Understand the service procedures
before commencing any work.
• Ensure all starting devices are
removed or isolated before beginning
any work on engine or plant.
• Ensure the work area is clean,
dry, well ventilated and has adequate
lighting.
• Ensure that all personnel using
equipment or processes in connection
with the maintenance of plant and
machinery have received adequate
and suitable training.

T SERIES ENGINES OPERATORS' HANDBOOK
Table 2 gives technical data for all the
engines in the Lister Petter T Series.
2.1 COMBUSTION AIR
Engine performance is affected by
ambient temperature, which means the
temperatureoftheairenteringtheengine.
The temperature of the combustion air
is measured at the air manifold inlet,
or the air cleaner. The temperature
of the cooling air is measured at the
ywheel fan inlet. The higher of these
two temperatures is taken as being
ambient temperature as far as engine
ratings are concerned.
Every effort should be taken to
ensure that the air cleaner draws
in combustion air at the prevailing
ambient temperature. Any increase in
combustion air temperature above the
2. TECHNICAL DATA AND INFORMATION
standard engine reference condition
of 25°C (77°F) will incur an engine
derate factor.
The engines are able to run satisfactorily
at ambient temperatures up to 25°C
(77°F) without derating. Above this
temperature, the rated power must
be reduced in accordance with the
relevant standard.
Engines: ISO 3046
Generating Sets: ISO 8528
The maximum permitted ambient
temperature is 52°C (125°F).
2.2 COOLING SYSTEM
The engine is air cooled, by means of
an integral ywheel fan. The cooling
air is distributed by means of a cowling
and bafe plates tted to the cylinder
barrels.

T SERIES ENGINES OPERATORS' HANDBOOK
4. ENGINE FLUIDS
4.1 OIL SPECIFICATION
To assist engine running-in, all engines
are despatched with an initial fill
lubricating oil which must be changed,
with the lter, after the rst 100 hours.
All subsequent oil changes must
be as specied in 5.2. Maintenance
Schedule.
The engines must be run on heavy-
duty lubricating oils that at least
meet the requirements of one of the
following:
APICC MIL-L-46152B
DEF2101D MIL-L-2104B
Straight mineral oils are not suitable,
neither are oils of less detergency than
specied.
Higher specication oils meeting API
CD, API CE and API CF-4 are more
commonly available than API CC. The
use of these oils in new engines is
acceptable for topping up the rst-ll
and following the rst 100 hours when
running-in has been completed.
These oils are particularly suited to
engines running at a high-load factor,
or in conjunction with high ambient
temperatures. They must also be used
where the sulphur content of the fuel
exceeds 0.5%.
The oil must be suitable for 250-hour
oil changes without undue degradation,
with sump temperatures reaching
150°C (302°F) under severe tropical
conditions, and 120°C (248°F) under
normal conditions.
For engines in long running installations
Lister Petter should be consulted.
4.2 The chart shows the recommended oil viscosity grades for different temperature °C ranges.
A: intermittent running; B: synthetic oils only. Note:°F = (1.8 x °C) + 32.
