ENGINE AND LOWER ENGINE UNITS
Mount the lower c asing and tighten the scre ws at a moment of 1daNm.
The watertight-sealing is done with RHODORSEAL 5661; girdle D must be 3 mm thick.
Do not forget to replace the two crescent-shaped fittings (in the A are a) with new
ones.
-the fl ywheel: beforehand oil t he face for t he pl acing of the flywheel on the crank-
s haft, using LOCTITE AUTOFORM; apply on the screws one drop of LOCTITE
FRENETANCH and tighten them at 5 - 5.5 daNm, after having blocked the flywheel
by means of the cogged sector MOT 582.
-the clutch (be cautious about the centring): scre ws are tightened at 2 daNm;
-the water-pump (the watertight-sealing is done with LOCTITE 518, the H girdle
must be of 0.6 - 1 mm). The screws are tightened at a couple of 1 - 2 daNm.

SUGGESTIONS
The contac
t is set
If the voltage < the minimal voltage, then the battery may be flat.
Check the charging circuit, in order to detect the cause of the problem.
If the voltage > the maximal voltage, then it is possible that the
battery may be overcharged.
Check the charging voltage to be correct, with and without consumers.
In idle mode
If the vo ltage < the minimal voltage, then the charging voltage is too
small.
Check the charging circuit, in order to detect the cause of the problem.
If th e voltage > the maximal voltage, then the charge of the battery is
too high.
The vo ltage regulator is faulty.
Remedy this problem, and then check the level of the electrolyte in the
ba ttery.

CLUTCH
It is a dry mono-disc clutch with hydraulic
command. The clutch mec hanism has a diaphragm
spring.
The clut ch d isc has an elastic hub.
Th e su pply of the hydraulic circuit is done
with liquid from the brake-liquid tank. The principle of this command is the same
as that of a brake command.
The cl utch pedal operates on the emitting
cy linder, which transmits the liquid under pres-
sure to a concentric hydraulic receiver, the mo-
bile part of which acts directly on the diaphragm
spring.
The hydrau lic receiver is fixed on the clutch crankcase through the agency of two screws.
