The amount of oil to be introduced in the
engine is 2.7 liters - without replacing the oi l-
filter - or 2.9 liters, after re placing the filter.
The minimum oil pre ssure at 80
o is:
-in the idle mode 1 bar
-at 4000 rot/min 3 bar
The oil pump belongs to the “gearwheel”
type. Take off the cap and a lso the clapper of
the oil-pump.
To check:
* play A (mm): - min. 0.110
- max. 0.294 * play B (mm):
-min. 0.02
- max. 0.86.
CAUTION!
P rotect the distribution and alternator belt in order to avoid water-
or cleaning substance projection on them.

DIS M O UNT ING
The following are dismounting:-the water conduit and the oil-l evel-
gauge guide; their watert ight sealing is
done with rubbe r rings which must be re-
placed for every dismantlement; -the clutch;
-t he engine flywhe e l, bl oc ked by
means of MOT 582;
-the lower c rankcase;
-the pinion of the crankshaft;
-the stretching runner/ pulley;
-the water-pump;
-the oil-pump
Per f o r m co nn e cting rods caps
identification in regards t o connecting rod
body. To
be taken off:
-the caps of t he connecting rod a nd
the bushes;
-the jacket-maintaining device;
the jacket-piston-rod set; -the bearing caps and their bushing;
-the shaft and the axial play bushes;
-the bushes on the block.
The axes of the pistons are taken apart .
The piston is placed on i ts stand, after
positioning the piston bolt (a xis) with the
release hole (t wo lines T for position-find-
ing the centre of the hole will make align-
ment easier). The bol ts are taken off in a pressing-
machine by means of the E extraction
CAUTION!
Do not use punchers for line-
up m arking in order to avoid fis-
sures; use an indelible pen.

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.

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.
