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.

1. Longitudinal adiustment :
Check
the clearance of the front door with the
front wing and the rear door : J=6+_3mm
If necessary. add or withdraw the adjustment shims
( thickness 1 or 2 mm ) at <( a 1) and << b to_ a) Fitting shims at SC a u :
Remove screw (2) and loosen the 2 screws ( 1).
Slide the shims between hody and hinge.
Fit screw (2) and tighten the three fixing
nuts of upper hinge.
b) Fitting shims at <, b n :
Remove the two fixing screws (4) for distance
strop (3) and tilt it.
Loosen the two screws (5 ).
Slide the shims between body &hinge and
retighten fixing screws (5 ). 2. Transversal and height adjustments :
Loosen hinge fixing screws.
Move the door vertically in order to obtain a
clearance of : Jl = 7 +‘2mm
between the upper port of the window frame and
the roof edging.
Check ‘the continuity of the a light line 1) and
the difference in alignment between door and
front wing. Inset of front door in relation to
front wing = maximum of 2 mm.
Tighten the hinge fixing SCWNS and fix door
check (3) using screws (“4). 3. Adjustment of door striking plate engagement :
Loosen. the two door striking plate fixing screws
and adjust the plate so that correct locking and
sufficient compression of the door rubber sealing
strips is obtained.
If necessary, fit shims at (cc )P.
The rear edge of the front door must not stand
proud by more than 2 mm with respect to the front
edge of the rear door.
Tighten the screws (6 ).
