ASSEMBLING THE CONNECTING RODS AND
PISTONS
The pistons are marked with an arrow stamped
onto their heads indicating the
flywheel end.
The connecting rods have no particular mounting
direction, but nevertheless the
bearin
g stop lugs
should be
positioned on the same side.
Follow the instructions below when assembling
the piston and the connecting rod:
- place the bush
B13 on the support and fix the
piston (with the arrow pointing upwards) onto
the bush with the clip,
92310R
- lubricate the centring device and the gudgeon
pin with engine oil,
- push the gudgeon pin into the mounting to
check that it slides freely, and re-centre the pis-
ton if necessary,The followin
g operations must be carried out qui-
ckl
y in order to reduce the heat loss to a mini-
mum.
When the piece of solder reaches its melting poin
t
(turns into a droplet):
- wipe off the droplet of solder,
- engage the centring guide in the piston,
- fit the connecting rod into the piston,
- quickly push in the gudgeon pin until the guide
reaches the bottom of the support base.
Check that the gudgeon pin remains within the
piston diameter for any connecting rod position in
the piston.

91803G1 FITTING THE PISTON RINGS
Mount on the piston:
- the scraper ring (3),
- the taper compression piston ring (2), with the
"To
p" mark facing upwards,
- the upper piston ring (1), with the
"To
p" mark
facing upwards.
Once the seating of all the piston rings has been
adjusted, never alter this seating.
Oil and bed in the piston rings, seating the scrape
r
ring onto a solid part of the groove.Fit the "connecting rods - pistons - piston rings"
assemblies into the liners using the piston ring
compressor.
Before fitting the "liners - pistons - connecting
rods" assemblies into the cylinder block, do no
t
forget to fit the O-ring on each liner, ensuring
that it is not twisted.
Fit the assembly into the cylinder block in the pre-
established order, checking that a
0.1 mm shim
will pass freely between the liners.

Immobilise the liners using tool
Mot. 588.
92062R
Shims of the following thicknesses (mm) are avai-
lable from the Parts Department:
2.80; 2.85; 2.90;
2.95.
Refit the connecting rod shells and tighten the
nuts to a torque value of
4.2 daN.m.
Check:
- the end float of the connecting rods,
- that the assembly is able to rotate properly. Fit the crankshaft and the end float shims.
Lubricate the crankpins and the main bearing
journals with engine oil.
Refit the crankshaft bearing shells.
Apply a thin layer of
RHODORSEAL 5661 on bea-
ring
N°
1 zone (K) and tighten the bolts to
2.5 daN.m , then angle tighten to
43°

± 6°.
Check the end floatof the crankshaft, which
should be between:
-
0.045 and 0.852 mmwith wear,
-
0.045 and 0.252 mmwithout wear.
92314S MOUNTING THE BEARING SHELLS
The connecting rod bearing shells are identical.
The crankshaft bearing shells are grooved on the
cylinder block side.
92315R
The upper shell of bearing
No. 5 is a special one
and is also grooved.

Fit:
- the oil pump, checking that the centring dowls
are present, and tighten to a torque value of
2.5 daN.m,
- the two sprockets and chain of the oil pump,
and tighten the three bolts mounting the
sprocket to the hub to
1 daN.m,
- the crankshaft end cover, sealing it with
Loctite
518.
The bead (H) should be
0.6 to 1 mm wide and
should be applied as shown in the diagram be-
low. - the crankshaft seal (bearing No.1), using tool
Mot. 1129-01; this tool is designed to ensure an
offset seal bearing surface. Lubricate the lip
and the outside of the seal.
92319R
92067R
-the crankshaft end seal, using tool
Mot. 1128-
01; lubricate the lip and the outside diamete
r
of the seal.
Turn over the s
pacer if the old seal has marked
the bearin
g surface.

Method of tightening the cylinder head
90775S
Preseating of the gasket:
Initial tightening to
2 daN, followed by angula
r
tightening to
97°
± 2° in the recommended or-
der:
- tighten bolts
1-2,
- tighten bolts
3-4-5-6,
- tighten bolts
7-8-9-10.
Seatin
g of the gasket:
Wait
3 minutes (settling time).
Ti
ghtening:
- Slacken bolts
1-2.
Retighten bolts
1-2 to
2 daN.m, then angle
tighten to
97
° ±
2°.
- Slacken bolts
3-4-5-6.
Retighten bolts
3-4-5-6 to
2 daN.m, then angle
tighten to
97
° ±
2°.
- Slacken bolts
7-8-9-10.
Retighten bolts
7-8-9-10 to
2 daN.m, then angle
tighten to
97
° ±
2°.
There is no cylinder head retightening operation.Refit the rocker shaft, positioning the mark (1) on
the timing side and the bolts (A) at (B).
92063R
NOTE :
There are two sizes of bolts (A) :
M8×
100
and M8×
125.
Refit:
- the rocker shaft mounting bolts (2), tightening
them to a torque of
2.3 daN.m and not forge
t-
ting to lubricate the threads and underneath
the bolt heads with engine oil,
- the cylinder head cover without tightening i
t
in order to facilitate the setting of the timing,
- the crankshaft sprocket.
