6A-134 ENGINE REPAIR
NOTE:
• *The height determining the thickness of gaskets is
referred to the maximum pistons overhanging once
the four pistons have been measured
• To do the measurements in the pistons place them in
T.D.C. position using a dial gauge.
• The difference between the minimum and
maximum heights of the four pistons overthanging
must be
£ £ £ £ £
0,2 mm.
• The cylinder head gasket comes in a kit of required
gaskets to carry out complete repairs of the engine;
this is the one with the greatest thickness. Obviously,
it is also supplied separately according to required
thickness.

Engine flywheel housing
18) Install flywheel housing (31) aligning with fixings and dust
protection plate.
19) Fix housing with its screws tightened to the specified
tightening torque.
Tightening torque fixing involvent of the flywheel:
7 ÷ 10 Kg-m (70 ÷ 100 Nm)

Flywheel synchronization
NOTE:
• The engine flywheel must be synchronized with the
pistons, because its connection with crankshaft is
no prepared to be in a unique position.
• There is a small play between the flywheel and its
screws, accordingly, before tightening the screws of
the engine flywheel you will have to locate its position
as described now.
20) To carry out the flywheel synchronization do as follows:
• Ensure the screws fixing the engine flywheel are loose and
that the flywheel can move by the amount allowed by the
screws play.
• Turn crankshaft till piston nº 1 is in the T.D.C. position.
• Turn crankshaft ~ 90º in the opposite direction.
• Using the dial gauge (G) and the magnetic support, deter-
mine the exact point of equilibrium between pistons n°1
and n°2 as follows.
With comparator touching on the head of the piston n° 1,
put comparator to zero; then, displace comparator, from
magnetic support till touching the head of the piston n° 2
and determine displacement of the needle.
If there is no displacement of the needle, pistons n° 1 and n°
2 are perfectly equilibrated; otherwise, it is necessary to
share the value measured by the needle rotating adequately
the crankshaft.
