Clutch: Precautions for the repair
20A
Before removing the clutch, check:
-The direction of fitting for the clutch plate.
Before refitting the clutch, check:
-The flywheel friction track (no scratches or blue
stains),
-The crankshaft bearing (no sticking),
-The engine and gearbox seals (replace if necessary),
-The sliding action of the clutch plate on the output
shaft,
-The guide of the thrust bearing and clutch fork (no
wear or scratches).
During refitting:
Check the direction of the clutch plate.
Centre the clutch plate using the (Emb. 1518) or (Emb.
1780).
Gradually torque tighten the clutch pressure plate
bolts.
After refitting, check:
-The clutch play (for a cable operated vehicle),
-Bleeding of the hydraulic circuit (for vehicles with hy-
draulic controls).Special tooling required
Emb. 1518Set of clutch plate centr ing
mandrels
Emb. 1780Set of clutch plate centr ing
mandrels.
WARNING
To prevent the clutch from juddering or slipping, do
not grease the output shaft or the clutch plate hub.

bles - Products) to clean and degrease:
-the flywheel friction face,
-the clutch shaft splines.
II - REFITTING OPERATION FOR PART
CONCERNED
aFit the clutch plate, with the face (3) to the clutch
pressure plate end.aCentre the clutch plate using the (Emb. 1780) (4) .
aRefit:
-the clutch pressure plate,
-the clutch pressure plate bolts by gradually tighten-
ing them in a radial pattern.
aTorque tighten the clutch pressure plate bolts (23
N.m).
aRemove the (Emb. 1780) and (Mot. 1677).
III - FINAL OPERATION.
aRefit:
-the manual gearbox (see 21A, Manual gearbox,

WARNING
Prepare for the flow of fluid, and protect the sur-
rounding components.
WARNING
To avoid damaging the slave cylinder, do not coat
the gearbox output shaft with grease.
WARNING
Never operate the system when the slave cylin-
der is removed (even if it is connected to the
clutch pedal). There is a risk that the hydraulic
piston and the sla ve cylinder stop will be ejected.
Note:
To obtain optimum bleeding, pre-fill the clutch
thrust bearing when refitting the thrust bearing.

IMPORTANT
Before any operation on the sequential system, dis-
charge the accumulator using the Diagnostic tool.
WARNING
If any operation is carried out on the electro-hydrau-
