General information 1
Introduction
This Workshop Manual has been written for Perkins Technicians working at distributors to provide assistance
in the service and overhaul of Perkins 700 Series engines. It has been compiled for use in conjunction with
normal workshop practice and information contained in current service bulletins. Mention of certain accepted
practices therefore, has been purposely omitted in order to avoid repetition. For overhaul procedures the
assumption is made that the engine is removed from the application.
Note: With effect from engine number U------U806626D, a requirement of emissions legislation is that access
to adjustments that affect the engine’s exhaust emissions is limited to personnel approved by Perkins Engines
Company Limited. These adjustments are on the timing case, therefore, only Perkins approved personnel
should remove and fit the timing case. If there is doubt, contact your nearest Perkins Dealer/Distributor for
advice. Any claim including but not limited to warranty will not be acceptable to Perkins Engines Company
Limited if it can be seen that an adjustment has been made by a person not approved by Perkins.
How to use this manual
This manual is illustration and text based and is divided into 16 chapters. The illustrations and text in each
chapter follow the sequence for the complete disassembly of a particular assembly or component. Reassembly
is achieved by using the illustrations in reverse order from the rear of the chapter. Reference to renewing joints
has been omitted, it being understood that this will be carried out when applicable. Similarly, it is understood
that in reassembly and inspection, all parts are to be thoroughly cleaned and lubricated, and where present,
burrs and scale are to be removed. Any open ports of high precision components, e.g. fuel injection equipment
exposed by dismantling, must be blanked off until reassembly, to prevent the ingress of debris.
When fitting setscrews into "through" holes into the interior of the engine, the threads should be cleaned and
fitted with a suitable sealant. Throughout this manual, whenever the "left" or "right" of the engine is referred to,
it is that side of the engine when viewed from the flywheel end.
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, where relevant.
POWERPART recommended consumable products are listed on page 10. Reference to the relevant
consumable products is also made at the beginning of each operation.
Data and dimensions are provided as an integral part of each operation and also in Chapter 2, Specifications.
Always use the full engine number to order new parts.
Read and remember the "Safety precautions" on page 6. They are given for your protection and must
be used at all times.
Note: Most of the information included in the User’s Handbook (Chapters 1 to 6), has not been repeated in
this Workshop Manual. The two publications should be used together.
The engines referred to in this manual are the UA (3,0 litre - direct injection), the UB (2,6 litre - indirect injection)
and the UC (3,0 litre - turbocharged direct injection).
The engines conform to Stage 1 off-highway emissions to C1-8 mode cycle ref. ISO 8178 part 4.

The 3,0 litre versions are, water cooled, naturally aspirated or turbocharged, four cylinder diesel engine with
direct injection. They have been specifically designed for industrial and agricultural applications. The 2,6 litre
version, is a water cooled, naturally aspirated, four cylinder diesel engine with indirect injection. It has been
specifically designed for fork-lift truck applications. Where the information applies to only one engine type, this
will be indicated in the text and/or illustration by use of the particular code letters.
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.
