General information
Introduction
10
This workshop manual has been designed to provide
assistance in the service and the overhaul of Perkins
3012 (CV12) engines. Most of the general
information, which is included in the User’s Handbook
(Sections 1 to 9), has not been repeated in this
Workshop Manual and the two publications should be
used together.
Read the ’Safety precautions’ and remember them.
They are giv en for your protection and must be
applied at all times.
Danger is indicated in the text by two methods:
Warning! This indicates that there is a possible
danger to the person.
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.
Bank and cylinder bore identification
The left and right s ides of the engine are as seen from
the rear (flywheel) end. Where reference is made to
’A’ and ’B’ banks of cylinders: ’A’ bank is to the left and
’B’ bank to the right when viewed from the front end.
The cy linders are numbered from the front of the
crankcas e, A1 to A6 and B1 to B6.
To ensure that you use the correct information for
your specific engine type, refer to ’Engine
identification’ below.
Engine ident ification
The engine number is stamped on the data plate
which is fastened to the right side of the crankcase.
For early engines, a typical engine number is
6A27487U 59426V, which consists of these codes:
6A = Engine family
27487 = Engine number
U = Country of manufacture
59426 = Build line number
V = Year of manufacture
Engines produced after August 1994, have a new
engine number system. For these engines, a typical
number is: SGD 12 0012 U 1572 Y, which consists of
these codes:
SG = Engine applic ation
D = Engine type
12 = Number of engine cylinders
0012 = Engine specification number
U = The country of manufac ture
1572 = Build line number
Y = Year of manufacture
Units such as the fuel injection pump and
turbochargers have their own data plates.
If you need parts, service or information for your
engine, you must give the complete engine number to
your Perkins distributor.

General safety precautions
These safety precautions are important.
Reference must also be made to the local regulations
in the country of operation.
l Only use these engines in the type of application
for which they have been designed.
l Do not change the specification of the engine.
l Do not smoke when you put fuel in the tank .
l Clean away fuel which has been spilt. Material
which has been contaminated by fuel must be
moved to a safe place.
l Do not put fuel in the tank while the engine runs
(unless it is absolutely necessary).
l 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).
l Do not make adjustments that you do not
understand.
l Ensure that the engine does not run in a location
where it c an cause a concentration of toxic
emissions.
l Other persons must be kept at a safe distance
while the engine or equipment is in operation.
l Do not permit loose clothing or long hair near
moving parts.
l Keep away from moving parts during engine
operation. Warning! The fan cannot be seen
clearly while the engine runs.
l Do not operate the engine if a safety guard has
been removed.
l Do not remove the filler cap of the cooling system
while the engine is hot and while the coolant is
under pressure as dangerous hot coolant can be
discharged.
l Fuel and oil pipes MUST be inspected for cracks
or damage before they are fitted to the engine.
l 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.
l Disconnect the battery terminals before a repair is
made to the electrical system.
l Only one person must control the engine.
l Ensure that the engine is operated only from the
control panel or from the operator’s position.
l Be extremely careful if emergency repairs must be
made in adverse conditions.
l If your skin comes into contact with high pressure
fuel, obtain medical assistance immediately.

Read and use the instructions relevant to lift
equipment which are given on page 15.
Always use a safety cage to protect the operator
when a component is to be pressure tested in a
tank of water. Fit safety wires to secure the plugs
which seal the hose connections of a component
which is to be press ure tested.
Do not allow compressed air to contact your skin.
If compressed air enters your skin, obtain medical
help immediately.
Turbochargers operate at a high speed and at
high temperatures. Keep fingers, tools and other
items away from the inlet and outlet ports of the
turbocharger and prevent contact with hot
surfaces.
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 in a safe place to
prevent contamination.
Ensure that the control lever of the transmission
drive is in the ‘out-of-drive’ position before the
engine is started.
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.
Fit only genuine Perkins parts.

Safety
Engine lif t equipment
Use only the lift equipment which is designed for the
engine. The part number for the lift adaptor to use for
the 3012 engine is: 21825 822.
Use lift equipment or obtain assistance to lift heavy
engine components such as the cylinder block,
cy linder head, fly wheel housing, crankshaft and
flywheel.
Check the engine lift brackets for security before the
engine is lifted.
.
A
Asbestos joints
Some joints and gaskets contain compress ed
asbestos fibres in a rubber compound or in a metal
outer cover. The ’white’ asbestos (Chrysotile) which
is used is a safer type of asbestos and the danger of
damage to health is extremely small.
Contact with asbestos particles normally occurs at
joint edges or where a joint is damaged during
removal, or where a joint is removed by an abrasive
method.
To ensure that the risk is kept to a minimum, the
procedures given below must be followed when an
engine which has asbestos joints is dismantled or
assembled.
l Work in an area with good ventilation.
l Do NOT smoke.
l Use a hand scraper to remove the joints - do NOT
use a rotary wire brush.
l Ensure that the joint to be removed is wet with oil
or water to contain any loose particles.
l Spray all asbestos debris with water and place it in
a closed c ontainer which can be sealed for safe
disposal.
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.
Viton seals
Some seals used in engines and in components fitted
to engines are made from Viton.
Viton is used by many manufacturers and is a s afe
material under normal c onditions 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:
l Ensure that the components have cooled.
l Use Neoprene gloves and discard the gloves
safely after use.
l Wash the area with a calcium hydroxide solution
and then with clean water.
l Disposal of gloves and components which are
contaminated, must be in acc ordance with local
regulations.
If there is contamination of the skin or eyes, wash the
affected area with a continuous s upply of c lean water
or with a calcium hydroxide solution for 15-60
minutes. Obtain immediate medical attention.
