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

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 :
3.5 -mm pipe t 5.8 to 6 6 ft lbs
4 5 mm pipe 5 8 to 0 mN ( 0.8 to.0 9 ‘1 kg )
6 6 to 8 0 ft.lbs

9 to 11 mN (0 9 to 1 1 m.kg ) c ) Fittilzg :
I Only use joints of a quality compatible with LHM mineral fluid.
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

pipvs : pipes must not touch one another or any other component, nor may any other
unit, whether fixed or movable, exert any stress on them.
