ENGINE AND LOWER ENGINE UNITS
After the tu ning of the distri bution and the adjustment of the rocker-arms, the
following are further re-m ounted: -the cylinder-head cap, fitted with a new fitting; the screws are tightened at 1 daNm;
-the water-intake conduit and t he oil-level gauge guide (with new watert ight-
sealing ri ngs); -the cap of the distribution;
-the pulley of the crankshaft; the screw is first tightened at 2 daNm, then at 68
o+/-6o.
C
AUTION!
If the screw is not duly tightened, it c an come undone, which c an result in t he oi l-
pump not being operated and the distribution being disrupted, thus causing serious
damage to the engine.
-the intake and exhaust collectors: the screws are tightened at 2.5 daNm;
-the belt(s) of accessories: the same method as that for the distribution belt is used.
The stretching values are :
* alternator belt 263+/-10Hz
* Air-Comditioning (A.C) compressor belt 222+/-10Hz.

ST ARTING AND CHARGING
B.The light turns on when the engine is running
This indicates a charging fa ult, the cause of which may be: - the carrying belt of t he alternator i s broken, the charging conductor i s cut (+ con-
tinuous); - a fault with the alternator (rotor, stator, diodes or brushes);
- a fault with the voltage regulator;
- a voltage surge (overvoltage).
C. The customer / user claims a fault with the charging, as the
on-board light works correctly.
If the re gulated voltage is less than 13.5 V, the alternator is checked. The cause of the defect may be:
- a burnt diode;
- disconnected or cut live wire;
- the coal powder or the wear of the collector.
C
ONTROL OF VO LTAG E
A voltmeter is connected across the terminals of the battery and the voltage value is
read.
The engine is run until the needle of the voltmeter settles at the regulated voltage. This value should be within 13.5 and 14.8 V.
The maximum of consumer devices are connected: the voltage should remain between 13.5 and 14.5 V.
CAUTION!
In case electric arc welding i s being done on t he car, the battery and t he voltage
regulator will be compulsorily disconnected (t he alternator).

DIAGNOSING
Special device: Tester CLIP - SAGEM and accessories for physical measurements.
I
NSPE CT ION OF CHARG ING CIRCUIT
The CLI P - SAGEM tester allows the inspection of the alternator, by measuring the volt-
age and the curre nt supplied with, and without electri c consumers.
NOTE: The Ampere pincers are of the inductive type (0-1000 A). Its mounting
wi ll be done without disconnecting the battery, thus allowing for the memorized
da ta and the adapting values in the injection calculator to be preserved.
M ount the ammeter clamps directly to t he alternator exit, having the arrow oriented
towards this one
.
The measurements are effected in thre e steps: - measuring the battery voltage without contact on;
- measuring the regulated voltage and the current supplied without consumers;
-
measuring the regulated voltage and the current supplied with a maximum of consumers.
The values obtained as a result of t he measurements lead to the following interpretations: -the voltage of t he ‘empty’ battery < 12.3 V: so, the battery is flat;
With no consumers: -regulated voltage > 14.8 V: so, the regulator is faulty;
-regulated voltage (‘empty’) < 13.2 V or charging current < 2 A: so, there is a defect
of charging. With consumers: -regulated voltage > 14.8 V: so, the regulator is faulty;
-regulated voltage (‘empty’) < 12.7 V:the alternator charging current in regard to its
characteri stics must be checked.
IN TENSITY (A) EN GINEE7J
Rated intensity 75 80
Minimal intensity, which has to be supplied by the
altern ator to all working consumers 51 60
If the measured output is too little, the following will be checks:
-wear of alternator (collector brushes, etc.);
-battery connections;
-the mass braid of the engine;
-conformity of alternator;
-tension of carryi ng belt.
If the measured output is correct and the regulated voltage is too little, the cause may be:
-the car has too many electric consumers;
-the battery is flat. AL
