Setting the timing (continued).
NOTE:
If necessary, you can slightly rotate the pinions (10)and (7)anticlockwise in order to engage the belt.
The angular displacement value of the belt in relation to the pinions should not be more than half a tooth.
Remove tool
[5].
Act on the tensioner roller
(8)by its square «a», using tool [6]to check that the camshaft and injection
pump pinions can turn freely.
Position the belt tension instrument
[7]on the belt at «b».
Using tool
[6], act at «a»in the direction opposite to that of engine rotation, to obtain a tension value of
106 ± 2 SEEM units.
Tighten screws
(9), (5)and (6).
Remove tools
[7], [2], [3]and[4].
Rotate the crankshaft
8 timesin the normal direction of rotation.
Peg the flywheel, using tool
[2].
Peg the camshaft hub, using tool
[4].
Peg the injection pump hub, using tool
[3].
Slacken screws
(9), (5)and (6).
Position the belt tension instrument
[7]on the belt at «b».
Using tool
[6], act at «a»in the direction opposite to that of engine rotation, to obtain a tension value of
42 ± 2 SEEM units.

Refitting.
Place the pedal in the high position (contact at “a”).
Attach the cable yoke on the hook of the clutch pedal.
Fit a new clip
(3).
Fit the endpiece (4)to the bulkhead (fit with G6grease).
Clip the endpiece (5)on the gearbox.
Couple the cable to the lever (1).
Depress the clutch cable several times to lodge the cable in place.
Check that the endpiece (4) is correctly lodged on the bulkhead.
Check the operation of the automatic adjusting system.
After fitting the cable, pull the clutch lever in the inverse direction
(direction F), the lever should
move back when pulled by hand.
Press the clutch pedal very lightly and repeat the same operation. The lever should not move
back.
WARNING:If a system blockage is detected when checking, or if the pedal has been removed,
the pedal position must be adjusted. The correct positioning of the pedal is obtained by the
angular displacement of the stop supports
"a"and "b".

ELECTRICAL
SYSTEM
CHARGING CIRCUIT ALTERNATOR WITH MONOFUNCTION REGULATOR
Checking the alternator output.
Connect as shown in the diagram opposite, using an ammeter (A), a voltmeter (V),
and a rheostat
(R)or a Volt/Ammeter/Rheostat combination.
Referring to the vehicle’s equipment specification
(see table opposite), adjust the
engine speed and rheostat charge to obtain
U = 13.5 V.
Reminder:The excitation energising current will flow through the warning lamp;
check that the warning lamp comes on when the ignition is switched on. It shouldgo out when the engine has started
(accelerate slightly).
Checking the voltage regulator.
Set the rheostat to zero and disconnect all the electrical consumers.
Display
3000alternator rpm. If U alternator is > 14.7 V, the regulator is faulty.
Note:These tests should be performed with the engine hot and the battery fully
charged.
Method of reading the alternator speed.
Fit a reflecting shim on the pulley of the alternator.
Adjust a stroboscope to the frequency equivalent to the control speed.
(e.g. 2000 rpm = 2000/60 = 83 Hz).
Adjust the engine speed so that the shim appears fixed.
