Cylinder head gasket
Mount the MOT 484 device or MOT
588 clamps for jackets maintenance.
Check the cylinder head smoothness using
a lineal a nd a set of templates. The maximal admissible deformation: 0.05
mm. The cylinder head is not to be rectified!REMOU NT I NG
Clean the gasket-seating surface of the cyl-
inder head.
Mount the cylinder head with a new gasket.
Perform the dismounting operation s in the re-
verse order.
Tighten the cylinder head observing the cyl-
inder head tightening method described in chap-
ter 10 “Dismounting-Remounting” .
Mount the distribution belt ( see chapter 11
”Distribution belt”).
Adjust the tilters.
Perform the cooling circuit filling and purging
(see chapter 19 “ Filling and Purging” ).
REMARK:
At each operation implying battery dis-
mounting,
when reconnecting it, introduce the radio

ALTERNATOR – STARTER
B. The indicator is lighting, engine being running.
This shows a charging failure, which may be caused by:
- alternator driving belt broken, charging wire connected to alternator is broken (+ per-
manent);
-alternator failure(rotor, stator, diodes or brushes);
- voltage regulator failure;
- an over voltage.
C. Client is claiming a charging defect, but the luminous indicator is correctly oper-
ating.
If the adjusted voltage is smaller than 13.5 V, check the alternator.
The defect may be caused by : -worn diode;
-b roken phase;
- collector wear or coal dust.
VOLTAGE CHECKING
Connect a voltmeter to the battery plugs and read its voltage value.
Start the engine and speed the e ngine till the voltmeter needle i s set on the adjusted voltage.
This voltage must be between 13.5 V and 14.8 V
Connect maximum of consumers; the voltage must still between 13.5 V and 14.8 V.
AT T E N T I O N !
In case electric arch welding is performed on vehicle obligatory disconnect the bat-
tery and the voltage controller (alternator).

INTENSITY (A)E NGINEE 7J
Nominal intensity 7 5 80
Minimal intensity, generated by the alternator with
maximum of consumers under operation 5 1 60
DIAGNOSTIC
Special tool: CLIP tester and accessories for physical measurements.
CH ARGING CIRCUIT CHECKING
CLIP tester i s enabling the a lternator checking, by m easuring t he genera ted vol tage and
intensity with and without electric consumers.
REMARK: The ammeter pliers is of inductive type 0 ÷ 1000 A. Its mounting is done
without the battery disconnecting, enabling so the memorized data preserving and the
adapting values from the injection c omputer.
Mount the ammeter di rectly on t he alternator e xit, having t he arrow directed towards the
alternator.
The measurements are to be performed in three stages :
- measurement of the battery voltage with contact taken off;
- measurement without consumers of the adjusted voltage and generated intensity;
- measurement, with maximum of consumers, of the adjusted voltage and generated in-
tensity.
The values resulting further to the measurements, lead to following interpretations:
- voltage battery (without consumers) < 12.3 V – indicating discharged battery.
Without consumers :
- adjusted voltage > 14.8 V – indicating defective regulator;
- adjusted voltage < 13.2 or charging current < 2A – indicating charging failure.
With consumers:
- adjusted voltage > 14.8 – indicating defective regulator.
- adjusted voltage < 12.7 – indicating that alternator charging current must be checked
compared with its characteristics:
If the measured current is too small, check the following:
- alternator wear (collector brushes, etc);
- battery connections;
- engine mass stripe;
- drive belt tension.
If the measured current is correct and the adjusted voltage is too small, the cause may be: -the vehicle has too many electric consumers;
- the battery is discharged.
