WARNING: When valves are re
placed, it is essen-
tial to refit
(new) valves with the same part num-
ber
(1) as the previous ones, in order to prevent
an
y damage to the valve and seat.

The same part number can cover several mar-
kin
gs, and in this case the valves are fully inter-

geable.
Sim
ply check that the new valves with a different
markin
g do indeed correspond to the same part
number.

REFITTING THE CYLINDER HEAD
Lubricate all the parts.
Fit the valve spring seating washers (1).
Fit the seals (2) on the valve guides (3) using an 11
mm tubular socket wrench.
WARNING: When valves are bein
g replaced, it is
essential to refit
(new) valves having the same
markin
g (8) as the previous ones, in order to pre-
vent an
y damage to the valve and seat.
The same
part number can cover several mar-
kin
gs, and in this case the valves are fully inter-
chan
geable.
Sim
ply check that any new valves with a marking
different from the previous ones do indeed corre-
s
pond to the same part number.
10030R1
Refit in the following order:
- the new valves (4),
- the springs (5) (identical for the inlet and ex-
haust),
- the cups (6).
Compress the springs.
Fit the collets (7) (identical for the inlet and ex-
haust valves).

- the water pump,
92312R
- the three bolts mounting the oil pump sprocket
on the hub, and remove the sprocket and chain
assembly,
- the oil pump.
Carry out the marking of the big end shells with
reference to their bodies.
WARNING: Do not use a scriber tool for the mar-
kin
g, in order to avoid starting any cracks in the
connectin
g rods .
Use an indelible
pencil instead.
Remove:
- the big end shells and the bearings,
- the liner clamps
(Mot. 588),
- the "liners - pistons - connecting rods" assem-
blies,
- the bearing shells with their bearings (mar
k
them),
- the crankshaft (recover the side clearance
shims),
- the crankshaft bearings in the cylinder block.
EXTRACTING THE GUDGEON PINS
Place the piston on the "V" of the support with
the pin lined up with the clearance hole (two
marks (T) showing the centre of the hole assist this
alignment).
Use the extraction mandrel (E) to remove the
gudgeon pin on the press.

There is an arrow painted on the back of the belt
showing the direction of rotation and two marks
for the setting.
Line up the marks (N) on the belt with those on
the sprockets (L) and the housings (M).
Respect the direction of mounting of the belt and
begin to position it on the crankshaft sprocket.
Fit the sensor of
Mot. 1273.
98708R
Turn the knurled wheel of the sensor until it re-
leases (three "clicks").
Tension the belt using tool
Mot. 1135-01 until
the display of the
Mot. 1273 shows the re-
commended fitting value
.
Belt tension (in SEEM units)
Fitting value: 30 U.S.
Lock the tension wheel, carry out a check and ad-
just the value.
Rotate the crankshaft at least
three turns.
Check that the tension value is within the fitting
tension tolerance (
±10 %), and if not readjust it.
NOTE : Never refit a belt which has been remo-
ved.
Tighten nut (O) of the tension wheel to 5 daN.m.
It is essential to tighten the tension wheel nut to
a tor
que value of 5 daN.m to prevent any risk of
working loose which might damage the engine.
WARNING: Certain camshaft s
prockets have five
marks, but onl
y the rectangular mark on the face
of a tooth shows the TDC. The other marks are
used for ad
justing the valve rockers.
10072S
Only the camshaft sprockets with marks will be
available in future from the Parts De
partment.
