Introduction
The 2300 and 2800 Series engines are from Perkins Engines Company Limited, a world leader in the design
and manufacture of high-performance diesel engines.
Perkins approved assembly and quality standards, together with the latest technology, have been applied to
the manufacture of your engine to give you reliable and economic power.
This Workshop Manual has been designed to provide assistance in the service and the overhaul of Perkins
2300 and 2800 Series engines. Most of the general information, which is included in the User's Handbook
(Chapters 1 to 6), has not been repeated in this Workshop Manual and the two publications should be used
together.
To ensure that you use the relevant information for your specific engine type, refer to "Engine identification"
on page 6.
When reference is made to the "left" or "right" side of the engine, this is as seen from the flywheel end of the
engine.
Special tools have been made available and a list of these is given in Chapter 16, Special tools. Reference to
the relevant special tools is also made at the beginning of each operation.
Data and dimensions are included in Chapter 2, Specifications.
Read the "Safety precautions" on page 2 and remember them. They are given for your protection and must be
applied at all times.
In addition to the general safety precautions, danger to both operator and engine are highlighted by the
following conventions:
Warning! This indicates that there is a possible danger to the person (or the person and engine).
Caution: This indicates that there is a possible danger to the engine.
Note: Is used where the information is important, but there is not a danger.

Safety precautions
These safety precautions are important. You must refer also to the local regulations in the country of use.
Some items only apply to specific applications.
Always refer to the text of this handbook for specific warnings and cautions.
Only use these engines in the type of application for which they have been designed.
Do not change the specification of the engine.
Do not make adjustments that you do not understand.
Do not allow the engine to stand on its sump.
Do not smoke when you put fuel in the tank.
Clean away fuel which has been spilt. Material which has been contaminated by fuel must be moved to a
safe place.
Do not put fuel in the tank while the engine runs (unless it is absolutely necessary).
Do not clean, add lubricating oil, or adjust the engine while it runs (unless you have had the correct training;
even then extreme caution must be used to prevent injury).
Ensure that the engine does not run in a location where it can cause a concentration of toxic emissions.
Other persons must be kept at a safe distance while the engine or auxiliary equipment is in operation.
Do not permit loose clothing or long hair near moving parts.
Warning! Keep away from moving parts during engine operation. Some moving parts cannot be seen clearly
while the engine runs.
Do not operate the engine if a safety guard has been removed.
Do not remove the filler cap or any component of the coolant system while the engine is hot and while the
coolant is under pressure, because dangerous hot coolant can be discharged.
Do not allow sparks or fire near the batteries (especially when the batteries are on charge) because the
gases from the electrolyte are highly flammable. The battery fluid is dangerous to the skin and especially
to the eyes.
Disconnect the battery terminals before a repair is made to the electrical system. Always disconnect the
negative terminal first.
Only one person must control the engine.
Ensure that the engine is operated only from the control panel or from the operator's position.
If your skin comes into contact with high-pressure fuel, obtain medical assistance immediately.
Diesel fuel and lubricating oil (especially used lubricating oil) can damage the skin of certain persons.
Protect your hands with gloves or a special solution to protect the skin.
Do not wear clothing which is contaminated by lubricating oil. Do not put material which is contaminated
with oil into the pockets.
Discard used lubricating oil and coolant in accordance with local regulations to prevent contamination.
The combustible material of some components of the engine (for example certain seals) can become
extremely dangerous if it is burned. Never allow this burnt material to come into contact with the skin or with
the eyes.

Always use a safety cage to protect the operator when a component is to be pressure tested in a container
of water. Fit safety wires to secure the plugs which seal the hose connections of a component which is to
be pressure tested.
Do not allow compressed air to contact your skin. If compressed air enters your skin, obtain medical help
immediately.
Turbochargers operate at high speed and at high temperatures. Keep fingers, tools and debris away from
the inlet and outlet ports of the turbocharger and prevent contact with hot surfaces.
Some components are not waterproof and should not be washed with a high-pressure water jet or steam.
Fit only genuine Perkins parts.

Viton seals
Some seals used in engines and in components fitted to engines are made from Viton (fluorocarbon).
Viton is used by many manufacturers and is a safe material under normal conditions of operation.
If Viton is burned, a product of this burnt material is an acid which is extremely dangerous. Never allow this
burnt material to come into contact with the skin or with the eyes.
If it is necessary to come into contact with components which have been burnt, ensure that the precautions
which follow are used:
Ensure that the components have cooled.
Use Neoprene gloves and discard the gloves safely after use.
Wash the area with a calcium hydroxide solution and then with clean water.
Disposal of gloves and components which are contaminated, must be in accordance with local regulations.
If there is contamination of the skin or eyes, wash the affected area with a continuous supply of clean water or
with a calcium hydroxide solution for 15-60 minutes. Obtain immediate medical attention.
Welding
Welding can cause damage to the electronic components fitted to the engine. If welding is necessary, the
precautions which follow must be undertaken before and during the welding operation.
Cautions:
Switch off the engine.
Disconnect the cable from the negative terminal of the battery. If the machine is fitted with a battery
disconnect the switch then open the switch.
If welding to the engine, remove the ECM (electronic control module).
If welding onto the machine chassis, ensure that the earth clamp is attached as close to the welding point
as possible and NOT near to the ECM.
If it is necessary to weld near to the ECM, remove the ECM from the engine.
Environmental protection
There is legislation to protect the environment from the incorrect disposal of used lubricating oil. To ensure that
the environment is protected, consult your Local Authority who can give advice.

Engine identification
If you need parts, service or information for your engine, you must give the complete engine number. The
engine number is stamped on a data plate which is fastened to the right side of the engine.
A typical engine number is: HGA060125U 1103H, which consists of these codes:
H
Code for engine capacity
Engine application
G
A
Engine type
06
0125
U
Number of engine cylinders
Engine specification number
The country of manufacture
Build line number
1103
H
Year of manufacture
Engine lift equipment
A dry engine weighs approximately 1551 kg (3,419 lb). Ensure that the lift equipment used is suitable. An
adjustable lifting beam should be used and the chains or cables must be parallel to each other during use.
Before the engine is lifted:
Always use lift equipment of the approved type and of the correct capacity to lift the engine. Never use a
single lift bracket to raise an engine.
Check the engine lift brackets for damage and security before the engine is lifted.
Use suitable lift equipment or obtain assistance to lift heavy engine components such as the cylinder block,
cylinder head, damper unit, flywheel housing, crankshaft and flywheel.
Warning! The lifting eyes which are fitted to the engine must be used for lifting only the engine. Do NOT use
them to lift the engine if it is still attached to its driven unit.

Recommended torque figures
Exceptions to these torque figures are given in the Workshop Manual where necessary.
Before any components are fitted to the engine, ensure that they are in a new or close to new condition. Bolts
or threads must not be worn or damaged. Components must be free from rust or other corrosion. Clean with
a non-corrosive cleaner if necessary. Do not lubricate the threads of fasteners. Rust preventative which has
been applied by the component supplier for shipping and storage is acceptable. Certain components may
require an application of a particular lubricant, details are given in the Workshop Manual where relevant.
