USE OF THE MANUAL
In this manual you will find three major chapters:
- specifications,
- removal of en
gine,
- reassembl
y of engine.
To repair a component on the vehicle refer to the
Workshop Repair Manual and Technical Notes.
UNITS OF MEASUREMENT
- All the dimensions are expressed in millimetres,
mm (unless otherwise indicated).
The tightening torques:
- in decaNewton metres daN.m
(reminder:
1 daN.m = 1.02 m.kg).
The tightening torques without tolerances
must be kept within
±10°.
- in degrees, the tightening torques without to-
lerances must be kept within
±3 %.
The pressures are in
bars.

WARNING: When valves are re

tial to refit
(new) valves with the same part num-

- the distributor with the wiring loom,
- the fuel pump (if fitted) with new seals,
- the thermostat support, making it tight 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 seal, using mounting bush
Mot. 1127-01;
this tool is designed to obtain an offset seat fo

Lubricate the camshaft.
Refit the camshaft and its flange.
Check:
- the end play which should be between
0.06 and
0.015 mm; if this is not the case, the flange o
r
the camshaft are to blame,
92102-1R
- the camshaft sprocket, immobilising it with tool
Mot. 799-01, and tighten the bolt to a torque
value of
4.5 daN.m (lubricate the thread an

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.
