Downloaded from www.Manualslib.com manuals search engine Op. MA. 640-O 1 II CHECKING AND ADJUSTING :
1. Checking the operation of the air-conditioning :
Faulty operation may be due to the following
Insufficient quantity of R.12 fluid, caused by
improper filling 01 a leak.
Water in the system.
Insufficient quantity of fluid may be detected by examining the transparent index mark of the de-watering tank.
This lack of fluid would be shown up by the appearance of air-bubbles during operation.
The presence of water is shown up by the formation of a small quantity of ice near the pressure release valve
which causes irregular functioning of the system.
In both cases. the system must be drained. the circuits niust be put under vwzuum (to eliminate any trace of
water ). and refilled with R.12 fluid. 2. Corburation
: Adjusting the idling speeds (as soon as electric coolinq fans cut out )
a) Vc,hirlcs wi/hou/ loryue con wrtcr :
Engine idling speed 850 to 900 rpm ( compressor switched off )
Fast idling speed 1000 to 1050 rpm ( compressor in operation )
b) Vrhirles with torque co~twrt~~r
Engine idling speed 700 to 750 rpm ( compressor switched off )
Fast idling speed 725 to 775 rpm ( handbrake on, vehicle immobilised. one gear engaged, and compressor
switched off 1
The fast idling speed is adjustable by means of adjusting screw located on top of the vacuum capsule on the
cmburettor. NOTE
: In case the fast idle is impossible to obtain, the vacuum capsule may be moved ( slacken both fixing
screws on carburettor ). in order to reduce the clearance at the fixing point of the rod controlling the first
choke butterfly opening. 3. Adjusting the pulleys :
Camshaft pulley-water pump pulley no aligning to be carried out
Toothed belt tensioner-water pump pulley L = 2’ - 0.5 mm. this value to be obtained by placing shims
between the tensioner and its mounting plate. c
Water pump /
In
Alternator drive
Tensioner
Compressor-water pump alignment to within 0.5 mm by placing shims ( 1 ) between the compressor mounting
plo& and the clutch housing.
Tensioner -compressor alignment to within 0.5 mm by
movement of the tensioner mounting plate in its slots. 4. Tensioning the belts :
Trapezoidal belts for compressor :
- Fitting tension 40 to 50 daN ( 40 to 45 kg ) ( 88 to 99 lb )
- Operating tension 25 daN ( 25 kq ) ( 55 lb )
- Toothed belt driving water-pump : 15 to 18 doN ( 15 to 18 kg ) ( 33 to 40 Ib ) NOTE
: Insufficient tension will considerably reduce the reliability of the toothed belt.
A tension stronger than 18 daN ( 18 kg ) ( 40 lb ) will cause the belt to whistle.
Consequently, adjust the belt at the limit of the noise : tension it until it whistles while running. then reduce
tension until the noise disappears.

a) It is imperative to wear goggles
b ) Do not smoke R 12 fluid,in the presence of a flame turns into a toxic gas.
c) Never heat any section of the refrigerating system.
d) Never switch on the refrigerating system if both electric cooling fans are not connected
e ) Never check the compressor oil level without first having drained the refrigerating circuit.
f ) Never use any oil other than TOTAL (( LUNARIA 25 H, SUNISO No 5 or TEXACO CAPELLA (( E 1) grade 500
g ) Never use refrigerating fluid other than R.12.
NOTE Refrigerating fluid may- be sold under different names : FORANE (( 12 )), FLUGENE (( 12 ))! FREON ((12 ))
( the most important feature is the number (( 12 H which defines the fluid’s properties ).
IMPORTANT NOTES
A. The compressor
MUST NEVER b e switched on when the circuit has been drained of its refrigerating fluid.
during work ‘being carried out in the workshop. for example,. Indeed, in these conditions,
the compressor
would be functioning in air, and would deteriorate rapidly.
‘Consequently, in case of an exchange of compressor necessitating draining the system of its refrigerating
fluid, in a workshop not equipped with the necessary equipment for refilling ( SOGEV equipment )
IT IS
IMPERATIVE,
before driving the vehicle to another workshop equipped with the special equipment. to carry
out the following
- To leave the blanking plugs on the compressor. in order to avoid ingress of air ( the new compressor contains
refrigerating fluid ).
- To blank the intake and outlet hoses and to fix them tempororily.
- Todisconnect the supply lead to the electro-magnetic compressor clutch
( lead with white sleeve ).
NOTE : We remind you that if the circuit has been in contact with the atmosphere, it is necessary to replace
the de-watering tank, and the compressor oil.
B. Slight oil seepage is permissible at the front bearing of the air-conditioning compressor.
Compressors showing such a seepage, and being replaced OS a result, will not be accepted under warranty.
