SPECIFICATION
British Leyland UK Limited is constantly seeking ways to improve the specification of
its vehicles and alterations take place continually. While every effort is made to produce
up-to-date literature this Manual should not be regarded as an infallible guide to current
specifications. Further the specification details set out
in this Manual apply toa range of
vehicles and not to any particular one.
Distributors and Dealers are not agents of British Leyland
UK Limited and have
absolutely no authority to bind British Leyland

INTRODUCTION
The purpose of this manual is to assist skilled mechanics in the efficient repair and maintenance of British Leyland
vehicles. Using the appropriate service tools and carrying out the procedures as detailed will enable the operations to be
completed in the time stated in the 'Repair Operation Times'.
Indexing
For convenience, the manual is divided into a number of divisions.Page 01.3 lists the titles and reference number of the
various divisions.
A list of the operations within each division appears in alphabetical order on the page preceding each division.
Operation Numbering
A master index of numbered operations has been compiled for universal application to all vehicles manufactured by the
British Leyland Motor Corporation and, therefore, because of the different specifications of various models, continuity of the
numbering sequence cannot be maintained throughout this manual.
Each operation described in the manual is allocated a number from the master index and cross-referswith an identical
number in the 'Repair Operation Times'. The number consists of six digits arranged in three pairs.
Each instruction within an operation has a sequence number and, to complete the operation in the minimum time, it is
essential that the instructions are performed in numerical sequence commencing at
1 unless otherwise stated. Where
applicable, the sequence numbers identify the relevant components in .theappropriate illustration.
EmissionControl Equipment
With the exception of Section
17, all remaining sections of this manual relate to basic vehicles not fitted with emission
control equipment. Where an operation is affected by the presence of this equipment, refer also to Emission Control (Section
17).
ServiceTools
Where performance of an operation requires the use of a service tool, the tool number is quoted under the operation
heading and is repeated in, or following, the instruction involving its use. An illustrated list of all necessary tools is included in
section
99.
References
References to the left- or right-hand side in the manual are made when viewing from the rear. With the engine and
gearbox assembly removed, the 'timing cover' end of the engine is referred to as the front. A key to abbreviations and
symbols is given on page 01.5
REPAIRS AND REPLACEMENTS
When service parts are required it is essential that only genuine British Leyland Stanpart or Unipart replacements are
used. Attention is particularly drawn to the following points concerning repairs and the fitting of replacement parts and
accessories.
Safety features embodied in the car may be impaired if other than genuine parts are fitted. In certain territories,
legislation prohibits the fitting of parts not to the vehicle manufacturer's specification. Torque wrench setting figures
given in the Repair Operation Manual must be strictly adhered to. Locking devices,where specified, must be fitted. If
the efficiency of a locking device is impaired during removal it must be renewed. Owners purchasing accessories while
travellingabroad should ensure that the accessory and its fitted location on the car conform to mandatory requirements
in their country of origin
The car warranty may be invalidated by the fitting of other than genuine British Leyland parts. All British Leyland
Stanpart or Unipart replacements have the full backing of the factory warranty.
British Leyland Distributors and Dealers are obliged to supply only genuine service parts.

LOCATION OF COMMISSION AND UNIT
NUMBER
The Commission Number is the identification number
which is required for registration and other purposes. It is
stamped gn a plate attached to the body adjacent to the
left-hand door striker plate and is visible when the door is
opened.
The significance of the Commission Number is as follows:
CF -
this prefix denotes TR6model range.
1234 - is the accumulated total build of this model.
U - denotes that the model was constructed to meet
a
U.S.A. specification.
The Commission Number plate also bears code symbols for
identification of the vehicles exterior colour, trim colour,
and trim material. Refer to page
04.6.
The Engine Number is stamped on a machined flange on
the left-hand side of the cylinder block. The significance of
the Engine Number and suffix is as follows:
CF
- this prefix denotesthe model range.
1234 - is the accumulated total build of this unit.
U - the engine was built to meet U.S.A. specifications.
E - denotes engine unit.
The Gearbox Number is stamped on the left-hand side of
the gearbox casing. The gearbox letters denote model range
and the numbers accumulated total build.
The Rear Axle Number is stamped on the bottom flange of
the axle housing. The letters denote model range and the
numbers the accumulated total build.
IMPORTANT: In all communications relating to Service
and spares it is essential to quote Commission Number,
paint and trim codes, and unit numbers (if applicable).

PAINT AND TRIM CODING SYSTEM
The commission number plate affixed to the scuttle side panel bears code symbols for identification of the vehicle's
exterior colour, trim material and trim colour.
Colour Code
Nine basic colours are allocated a number as shown in the table. Shades of these colours are classified as 1st shade, 2nd
shade, 3rd shade, etc. The number of each shade change prefixes the basic colour to indicate the shade colour.
The main trim material is identified by prefixing the colour code number with a letter, e.g.:

RECOMMENDED FUEL
The Triumph TR6 engme is designed to operate on fuel hanng
a minimum octane rating of 97(High compression engines)
OR 91 (Lower compression engines): this is equivalent to the British
4 star and 2 star rating respectively.
Where such fuels are not available and it is necessary to use fuels of lower or unknown rating, the ignition timing must be
retarded from the specified setting, just sufficiently to prevent audible detonation (pinking) under all operating conditions,
otherwise damage to the engine may occur.
IMPORTANT: When cars for the U.S.A. market enter the "United States" the ignition timing must be set to suit the use of
the recommended grade of fuel AND TO COMPLY WlTH REGULATIONS ON EMISSIONS FROM
THE CRANKCASE
AND EXHAUST.
ANTI-FREEZE SOLUTIONS
Only solutions which meet
B.S.I. 3151 or 3152 specifications may be used.
