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 
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

PRECAUTIONS WHEN CARRYING OUT WORK ON THE CAR 
1. Battery : 
a) Disconnect the negative terminal first, then the positive one. 
b) Ensure the battery is properly connected, with the negative terminal being connected 
to earth. 
c) Carefully connect both leads to the battery terminals, the negative lead being connected 
last. 
Before connecting the negative lead ensure that there is no flow of current. This can 
be established by briefly touching the negative terminal pith the lead end : sparks 
indicate a short circuit which must be corrected first. 
d) Before using the starter ensure that the two leads are correctly tightened on their 
respective terminals. $ 2. Alt ernator-Regulator : 
a) Do not rotate the alternator unless it is connected to the battery.

2 b) Before connecting the alternator ensure that the battery is correctly connected 
2 (negative terminal to earth ). 
c) Do not check the operation of the alternator by short-circuiting either the positive or 
the u EXC )) terminals and the earth terminal. 
d) Take care not to reverse the leads connected to the regulator. 
e) Do not attempt to re-energize the alternator : this is never necessary and in any case 
would damage both the alternator and the regulator. 
f ) Do not connect a suppressor capacitor at the u EXC )) terminal of the alternator or the 
regulator. 
g) Do not connect a charging unit to the battery and never carry out arc welding ( or spot 
welding) on the car chassis unless both the positive and the negative leads are 
disconnected from the battery. 3. Ignition coil : 
4. Q.I. Headlamps : 
a) Connect the supply lead of the coil to the external ballast resistor terminal and not to 
the coil itself. 
b) Connect the suppressor with a jump lead to the feed terminal of the coil. Only fit the 
suppressor recommended by the factory. 
a) Only replace a Q.I. bulb with the headlamps switched off. After having used the head- 
lamps, it is wise to let them cool down for five minutes before handling. 
b) Do not touch a Q.I. bulb with bare fingers. Any fingerprints on the bulb must be cleaned 
off with soapy water and the bulb dried with a lint-free cloth.

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

5. PRECAUTIONS TO BE TAKEN BEFORE WORKING ON THE HYDRAULIC SYSTEM : 
a) (.~rvJuI/)~ CIVOII the area of work, the unions and the unit to be removed 
Disconnect the lead from the negative terminal of the battery 
Only use petrol or lead-free petrol for cleaning.

- Place the vehicle in the G /arc B 
position. stop the engine. 
- Slacken the Pressure Requlator release screw. 
Wait until the front of the car has reached the low position 6, PRECAUTIONS TO BE TAKEN DURING REMOVAL : 
a) t3lnuk o!! the w~~tnl pi/~es with plugs, and rubber tubes with round pins of the correct diameter 
b) 
t3lmk of/ //IV op,c,/li,lg.s of components with pluqs of the correct diameter 
NOTE : Plugs and pins must be carefully cleaned before insertion. 7.. CHECK OR TEST OF HYDRAULIC UNITS : 
- Use 3654-T t~sf hc~~c-h equipped and designed for use with LHM fluid 
This bench is /)ciitltc’d ~IY’~‘~/ and its accessories are marked in green. 
- Never use the bench with another fluid or for testing components operating with another fluid (units of a (( D )) 
car using LHS2 for instance ). 
NOTE The (< Le Bozec )) pump used on test benches for checking DIESEL injectors can be resorted to for 
testing components operating with LHM mineral fluid provided that the bench is cleaned first. 8. PRECAUTIONS TO BE TAKEN DURING REFITTING : 
E steel pipes must be blown through with compressed air, 
5 rubber tubes and joints must be washed in petrol or white spirit and then dried with compressed air, 
= hydraulic units must also be cleaned with petrol or white spirit and blown through with compressed air. 
NOTE Renew all joints and seals during refittinq . 
b 
) 12rlbrijicntim : 
- Follow the indications as stated in the operations in the Manual.. 
- Joints and internal parts must be liqhtly oiled hefore fitting ( use mineral fluid LHM only ) 
L If parts in contact with hydraulic units have to be qreased use a mineral grease only ( as employed for 
Cardan shafts or bearings ).

I To connect a union proceed as follows : 
- Position sleeve-seal (( a u lightly coated with 
L,HM fluid; this sleeve seal must not reach the 
extremity of pipe (( b )). 
- Centre the pipe in the housinq by lininq it up 
with the axis of the hole, avoidinq all stress. 
( Ensure that the end u b )I of the pipe enters 
into the smali bore C< c )> j. 
Start screwing in the union nut by hand. 
- Tiqhten nut moderately : excessive force could 
cause a leak because of deformation of the pipe 
NOTE Tiqhteninq torques :

The design of the various seals ensures that their sealing action increases with fluid pressure The oiltiqhtness e 
is therefore not improved by greater tiqhtness of the unions
