Useful information

To clean components

It is important that the work area is kept clean and that

the components are protected from dirt and other

debris. Ensure that dirt does not contaminate the fuel

system.

Before a component is removed from the engine,

clean around the component and ensure that all

openings, disconnected hoses and pipes are sealed.

Remove, clean and inspect each component

carefully. If it is usable, put it in a clean dry place until

needed.  Ball and roller bearings must be cleaned

thoroughly and inspected.  If the bearings are usable,

they must be flushed in low viscosity oil and protected

with clean paper until needed.

Before the components are assembled, ensure that

the area is as free from dust and dirt as pos sible.

Inspect each component immediately before it is

fitted, wash all pipes and ports and pass  dry

compressed air through them before connections are

made.

Use suitable gloves for protection when components

are degreased or cleaned with trichloroethylene,

white spirit, etc.  Degreasing solutions which are

basically trichloroethane are not rec ommended.

Suitable fluids to clean and to protect

components

Warning!  Full information for the use of all the

products listed below and for their safe disposal, and

especially for the health and safety of the personnel

who use them, will be found in the Manufacturer’s

data.

Ardrox 667: Ardrox Limited, Brentford, Middlesex.

Maxan 774:Henkel Chemicals Limited, Edgeware

Road, London.

These products are basically methy lene chloride and

are safe to use on most metals for the removal of

carbon and to remove paint.  They can damage

rubber and most plastic materials.

Method of use

The components to be degreased must be lowered

completely into the degreasing solution.  Allow

enough time to elapse for the components to be

thoroughly cleaned.  Subsequently, the components

must be thoroughly  flushed in clean water.  In use,

maintain a layer of water at least 76 mm (3 inches)

deep above the cleaning fluid to ensure that vapour

and toxic gases are not released.

Warning!  Do NOT smoke near the container.

Protection for the eyes and for the skin must be used

always during the use of these fluids, and the

container must be in a place with good ventilation.

Duroclean 150 powder: Diversey Limited,

Northampton.

This product is basically an alkaline degreasing

solution and is safe to use on brass, copper and

ferrous metals.  It must not be used on aluminium,

lead, tin or zinc.

Method of use

It is recommended that Duroclean 150 is used with a

maximum concentration of 50 grams for each litre of

water.  The components to be degreased must be

lowered completely into the degreasing solution

which is heated to 65°C.

10

Leave to soak until all contamination has  been

removed.

Subsequently, the components must be thoroughly  

flushed in clean water.  If neces sary, a suitable

corrosion inhibitor can be added to the last quantity of

water.

Warning!  Protection for the eyes and for the skin

must be used always during the use of this product.

Crodafluid CR2: Croda Chemicals Limited, Goole,

Yorkshire.

This product is basically an acid solution with a

corrosion inhibitor.  It is used to remove corrosion

from components that are made of ferrous metals.

Method of use

Crodafluid CR2 must be contained in a tank that is

made from a material which is not affected by acid.

Before the process begins, the components must be

degreased before they are lowered completely into

the Crodafluid solution.  For medium to heavy

deposits of corrosion, the solution can be heated to

70°C. Inspect the components now and then to check

the results of the process.  Surface corrosion can be

removed in a short period of time.  The last operation

is to wash thoroughly the components in clean water.

Warning!  Protection for the eyes and for the skin

must be used always during the use of this product.

Diverspray 30:  Diversey Limited, Northampton.

This product is a moderate and basically alkaline

compound with corrosion inhibitors.  It is either

sprayed over the components to clean them, or is

contained in a tank, for the immersion and agitation of

the components.

Diverspray 30 may be added to water to wash

components if a corrosion inhibitor is necessary.  It is

used after other processes, such as corrosion

removal, are finished.

NALCO 2568 Powder: NALCO Limited, PO Box 11,

Winnington Avenue, Northwich  CW8 4DX

This product (which is supplied only in quantities of 25

kg) is an inhibited sulphamic acid and can be used for

the removal of hard deposits from the tube stack of

the oil cooler.

Warning!  The solution must be made and used in

accordance with the manufacturer’s instructions.

The NALCO 2568 powder should be mixed with clean

fresh water in the ratio which follows:

15 - 40 kg/Tonne of water

(15 - 40 lb/100 UK gallons of water)

When the action of the solution is finished, dip the

tube stack in a solution made from: 0,5 kg (1 lb) of

sodium carbonate to 25 litres (5 UK gallons) of hot

water.  The final operation is to dry the inside of the

tubes with compressed air.

Oil seals

Apply petroleum jelly to oil seals before they are fitted,

and do not damage the lip of the seal on sharp edges.

Unless other specifications apply, fit the seal with the

edge of the lip toward the bearing.

Hose connections

Do not use a screwdriver to remove hoses by force

because adaptors or pipe connections c an be

damaged.  Cut through the hose and then cut the

ends of the hose from the adaptor or pipe connection.

When a new hose is fitted, a suitable rubber lubricant

can be used instead of antifreeze, water or french

chalk.  Never lubricate a hose with oil or grease.

Gaskets, joints and ’O’ rings

Discard all used items if an engine or a component is

dismantled and fit only new and correct parts.

If a jointing compound is needed, ’Hylomar PL 32’

jointing compound is recommended for use, but on

metal joints ONLY.  Only a thin application is needed,

an excessive quantity of compound can restrict the

flow of fluids in pipes and passages.

Caution: ’Hylomar’ jointing compound must NOT be

used in contact with any fibre joints as the solvent

contained in ’Hylomar’ can damage the joint material.

Apply a small amount of a suitable lubricant to ’O’ ring

seals to prevent damage during assembly.

Locking devices

Split pins, lock plates and tab was hers which have

been used must be discarded.  Various methods to

retain securely the nuts of an engine are shown (A).

Stiffnuts can be used again only if they have not lost

their grip and the original torque is needed to turn

them.

There must be a minimum protrusion of one full

thread of the bolt or stud through the stiffnut when it is

tightened fully. Discard all stiffnuts  which have nylon

or fibre inserts.

Application of thread locking compounds

Remove all oil, grease and dirt from engine parts

before thread locking compounds are applied to

them. Most thread locking compounds have a date by

which they must be used, ensure that the compounds

used are within those dates.

Fits and clearances

The dimensions given in section 11C are acceptable

limits.  The components which have measurements

within these limits are acceptable for a complete

period of service.

Certain components which are worn by more than

these limits can be corrected in accordance with a

Service Reclamation Scheme (SRS).  Information

A

122

about the Service Reclamation Schemes is available

from the Serv ice Department at Perkins Engines

(Shrewsbury) Limited.

Applied torques

The specifications for applied torques, which are

given in section 11B, apply to some bolts and nuts

where damage or failure can occur if they are

incorrectly tightened.  Where joints are fitted, for

example, between the cylinder head and the

crankcas e, it is also important that bolts and nuts are

tightened evenly and gradually as instructed in the

assembly sequence. The torque wrenches, listed

below, are s uitable for the torque load requirements of

the 3012/CV12 engine, and are available from

Perkins Distributors.

8 to 54 Nm (6 to 40 lbf ft), 21825 846

30 to 150 Nm (20 to 110 lbf ft), 21825 991

70 to 310 Nm (50 to 230 lbf ft), 21825 992

Checks for cracks

When possible, it is recommended that components

which are affected by high stresses such as the

crankshaft, the connecting rods, the gears and the

cylinder liners are tested for cracks during overhaul.

They should also be checked for cracks when they

have been affected by an excessive load or impact. It

is recommended that ferrous components are tested

by the electro-magnetic method if possible. Portable

electro-magnetic test equipment is available from

Radalloyd Limited, Oadby, Leicester. Non-ferrous

components can be tested by the use of a dye

penetrant process such as ’Ardrox 996’, available

from Ardrox Limited, Brentford, Middlesex. The dye

penetrant must conform to one of the standards listed

below:

MIL-STD 271-E

MIL-L 25135

B.S. 5750

D.T.D. 929

Exchange units

It is recommended that unserviceable units are

returned, as complete as the new exchange unit, with

covers fitted to all openings and the joint faces

protected.  When necessary, protec t the unit, both

inside and outside, from corrosion.

Parts

To ensure maximum reliability, fit only genuine

PERKINS parts supplied by a PERKINS distributor.

These parts are made to the latest specification and

have a guarantee for 12 months.  The use of parts,

such as filter elements, which do not conform to

PERKINS standards, may reduce the life of the

engine and can affect the warranty.

If you need parts, spares or information for your

engine, give the complete engine number to your

Perkins distributor.  This will ens ure that the correct

parts can be obtained.

Recommended specific applied torques

Caution: The torque loads listed below apply to threads in an oil wet condition, unless the use of thread

locking compound is recommended.

Application of a torque specification is NOT enough to ensure that the relevant components are retained

securely as an assembly.  It is important to conform also to the recommendations for assembly and, if given,

the sequence in which the bolts or nuts must be tightened.  This information is given in the relevant section of

this publication.

If a bolt or nut is retained with a locking washer, lock plate or split pin, the specification for a torque load can

be exceeded, if nec essary, by the MINIMUM amount that is needed for correct assembly.
