1 cap ( in the K area ) a t hi n l ayer of
R HODORSEAL 5661 is applied.
The screws are tightened at 2.5 daNm,
and then at an angle of 43o+/-6o.
The axial play of the cranksha ft i s
checked; it must be within: * 0.045 and 0.852 with wear ;
* 0.045 and 0.252 without wear.

The axial bushes can have: 2.80 mm,
2.85 mm, 2.90 mm, 2.95 mm. The rod caps are m ounted and tightened
at 4.2 daNm.
To check:
-the horizontal play of the rods;
-the rotation of t he whole set.
To mount:
-the oi l-pump (c heck t he existence
of the c entri ng jacks); the screws are tight-
ened at 2.5 daNm;
-the pi nion and the c arrying c hain of
the oil-pump;
-the oil-seal ring on the front cap
(which is oi led), by means of t he MOT
550 device;
-the front cap of the crankshaft; the
w atertight-sealing is done with LOCTITE
518 (the girdl e must be 0.6 - 1mm thick);
-the oil-seal ri ng on no. 1 be aring -
by means of MOT 1129 - 01.
The bri m and the outer part of t he oil-
seal ring are oiled.

Mount the lower c asing and tighten the scre ws at a moment of 1daNm.
The watertight-sealing is done with RHODORSEAL 5661; girdle D must be 3 mm thick.
Do not forget to replace the two crescent-shaped fittings (in the A are a) with new
ones.
-the fl ywheel: beforehand oil t he face for t he pl acing of the flywheel on the crank-
s haft, using LOCTITE AUTOFORM; apply on the screws one drop of LOCTITE
FRENETANCH and tighten them at 5 - 5.5 daNm, after having blocked the flywheel
by means of the cogged sector MOT 582.
-the clutch (be cautious about the centring): scre ws are tightened at 2 daNm;
-the water-pump (the watertight-sealing is done with LOCTITE 518, the H girdle
must be of 0.6 - 1 mm). The screws are tightened at a couple of 1 - 2 daNm.

CYLINDER HEAD RE-MOUNTING
.The following are to be mounted:
-the jack for c ylinder-head centri ng
on the block; -the new cylinder-head fitting;
-the cylinder-head (aft er the stand
has been taken apart ); the joining surface
cylinder c rankcase- cylinder-he ad is care-
fully cleaned; -the cylinder-he ad scre ws (whose
threads and scre w-ends are oiled).
THE METHOD OF TIGHTENINGT THE CYLINDER-HEAD
1. Pre-compressing the fitting -a l l the scre ws a re tight ened at 2
da Nm, then at 97o+/- 2o, in th e or d er below:
-wait for 3 minut es - the
stabilization delay.
2. Combustion-head tightening-screws 1 - 2 are loosened till they
are totally free;
-sc rews 1 -2 a re ti ghte ne d at 2
daNm, t hen at 97
o+/-2o;
Screws no. 2 are tightened at
2.3 daNm , but nor before oiling the
threads. -the cylinder-head cap, without tight-
ening it (in orde r to be a ble then to set/
tune the distri bution); -the pinion of the crankshaft.
-t he op e ra t i on of l o ose n i ng a n d
tightening is repeated for the scre w groups
3-4-5-6-, then for 7-8-9-10.
The cylinder head is not restricted.To be mounted subsequently:
-the rocker-arm ra mp, by position-
ing marki ng no. 1 on the axis towards the
distribution;

After the tu ning of the distri bution and the adjustment of the rocker-arms, the
following are further re-m ounted: -the cylinder-head cap, fitted with a new fitting; the screws are tightened at 1 daNm;
-the water-intake conduit and t he oil-level gauge guide (with new watert ight-
sealing ri ngs); -the cap of the distribution;
-the pulley of the crankshaft; the screw is first tightened at 2 daNm, then at 68
o+/-6o.
C
AUTION!
If the screw is not duly tightened, it c an come undone, which c an result in t he oi l-
pump not being operated and the distribution being disrupted, thus causing serious
damage to the engine.
-the intake and exhaust collectors: the screws are tightened at 2.5 daNm;
-the belt(s) of accessories: the same method as that for the distribution belt is used.
The stretching values are :
* alternator belt 263+/-10Hz
* Air-Comditioning (A.C) compressor belt 222+/-10Hz.
