Introduction
This Workshop Manual has been written to provide assistance in the service and overhaul of
Perkins 4006-23, TAG1A, TAG2A and TAG3A engines. It should be used in conjunction with normal workshop
practise 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.
The engine conforms with USA (EPA/CARB) stage 2 and EEC stage 2 emissions legislation for agriculture,
construction and industrial applications.
Most of the general information which is included in the relevant User's Handbook has not been repeated in
this workshop manual and the two publications should be used together.
Where the information applies only to certain engine types, this is indicated in the text.
When reference is made to the "left" or "right" side of the engine, this is as seen from the flywheel end of the
engine.
When not working on the engine, ensure that all covers, blank flanges, doors, etc., are refitted to openings to
prevent the ingress of dirt, etc.
Please quote the engine type and serial number with all your enquiries. This will help us to help you. The type
and serial number are on a plate fitted to the crankcase.
If any doubt exists regarding the installation, use or application of the engine, the Installation Manual should
be consulted for further advice contact Applications Department at Perkins Engines (Stafford) Ltd.
Oil change intervals may be changed according to operating experience by agreement with Perkins Engines
(Stafford) Limited and subject to oil analysis being carried out at regular intervals.
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.
POWERPART recommended consumable products are listed under "POWERPART recommended
consumable products" on page 7. Reference to the relevant consumable products is also made at the
beginning of each operation.
Data and dimensions are included in Chapter 2, Specifications.
Read and remember the "General safety precautions" on page 4. They are given for your protection and must
be used 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.
