Downloaded from www.Manualslib.com manuals search engine HOW TO USE THE MANUAL
PRESENTATION
To facilitate the use of the manual. operations have been qrouped in three volumes
- Volume 1 contains
- the CHARACTERISTICS ADJUSTMENTS CHECKS
This volume is essential for all workshops for repairs or overhauls
Volume 2 contains the operations usually carried out and concerning
- REMOVAL and FITTlNG
- RECONDITIONING
- ELECTRICAL. HEATING and AIR-CONDITIONING SYSTEMS
BODYWORK
- Volume 3 deals with the CX Diesel.
cd
E The above volumes are sold separately. They are presented bound in dark red Fibrex with,a
1~ MULTO 1) type mechanism to facilitate the insertion of supplements or the extraction of a
-
cl3 particular operation required by the workshop
L
a COMPOSITION
Every volume comprises
- the list of operations contained in the volume
- these operations filed in numerical sequence
- the list of all the tools mentioned in the operations and the manufacturing drawings for special
tools which are not sold but are intended to be manufactured by the workshop itself (‘(MR)) tools).

Downloaded from www.Manualslib.com manuals search engine OPERATIONS
The sequence of operations has been devised in order to obtain the best standard of work in the
shortest possible time.
The numbering of the operations is made up as follows
a) The code letter for the car (/ MA 3) for all CX vehicles except CX vehicles with ,c Fuel Injection )I.
b ) A number made up of three figures denoting the unit or its component.
c ) A figure code designating the type of repair
- the figures 0 0 0 indicate the characteristics of the car
the figures 0 0 indicate the characteristics of the unit
- the figure 0 indicates checks and adjustments
the figures 1 4. 7 indicate removal or fitting
- the figures 2. 5. 8 indicate dismantling or reassembly and
the figures 3 6 9 indicate reconditioning
The thumb-indexing which corresponds to the list of operations enables the particular operation
to be found without difficulty. TOOLING
Special tooling is denoted in the text by a number followed by the letter ‘I
The part-numbers inferior to the 6000 series concern tools aiready in use and common to vehicles
previously introduced and to CX vehicles.
The 6000 series refers to tools specially designed for CX vehicles
Additional tools of local manufacture are indicated in the text by a number preceded by the index
MR manufacturing drawings for these tools appear at the end of the particular volume filed in
numerical order. TIGHTENING TORQUES :
Torques are expressed in the following units
either in metres Newton ( m.N ) the legal unit for measuring torque. with the corresponding
amount in metre-kilogrammes ( m.kg )
or in decanewtonmetres ( da Nm ) 9.8i Nm 1 m.kg ci.981 daNm
The numbers corresponding to the torques are (t rounded off 1)
Examples 2 m.N 0.2
m..kg 60 m.N 6
m.kg
IMPORTANT When a tightening torque figure is followed by the words 11 torque wrench 11 the
operution must without fail be carried out with a torque wrench.
IMPORTANT WlTHOUT FAIL after each operation or group of operations there is a chapter
headed (, TIGHTENING TORQUES ,,; the screws nuts or studs which are underlined
indicate
that they are of a special grade ,c SECURITY HARDWARE 1). When refitting it is ESSENTIAL
to use this type of HARDWARE TO THE EXCLUSION OF ANY OTHER. ADVISORY SERVICE

With the engine at idling speed :
- Unscrew the pressure-release screw on the pressure requlator by one or one and one half turns : a sound
, of leakage should be heard from the requlator.
= Retighten the release screw : cut-out must occur which results in a reduction in the running noise
emitted by the H P pump.
If not check in the following sequence
- that there is sufficient fluid in the reservoir,
- that the reservoir filter is clean and in good condition,
= that the H.P pump is primed and there is no air leak on the suction side of the pump,
- that the release screw of the pressure requlator is correctly tightened
