The over-he ight X must be between 0.02
mm and 0.09 mm.
Place the jackets in such way that :
-the difference between two joint jackets
to be maximum 0.05 mm;
- the over-height to be in ascending order
between cylinders 1 and 4;
- in case of an incorrect over-height, check
the over-height by m eans of a new kit of jack-
ets, i n order to see i f t he c ause i s the block or
the cylinders jacket or check the theoretical size
values of the block and of the jackets. When over-height is correctly obtained, per-
form the A, B, C, D assembly then mark with
numbers jackets, pistons and the bol ts from 1
to 4 (no.1 towards flywheel) so that the corre-
s pondence with the corresponding connecting
rods may be achieved.
Pistons bolts mounting
The pistons bolts are fixed in connecting rods
and free in pistons. Mount the pistons bolts by means of the
MOT 574-22 that is containing:
- a support for piston ( S);
- an extracting mandrel ( M);
- the piston supporting bushings (B);
- the bolts for mounting ( A) provided with
their centering guides (C ). Use an electric plate of
1500 W (electric
oven) for connecting rods heating. Place the connecting rods on the electric
plate so that connecting rod end surfaces are
in contact with the heating plate.
Check if the pistons bolts are freely gliding
in the new corresponding pistons. Mount the piston bolt E on the mounting
bolt A.
Sc rew the centering guide C till end and
then unscrew it for a quarter of turn.

The arrow marked on the piston head must
be oriented towards engine flywheel. The c onnecting rods ha ve no mounting
direction, but the ha lf-bearings spurs are to
be positioned on the same part. In order to assemble the piston and the
connecting rod, proceed as follows: -place the bushing B 13 on the support
and attach the piston (with the arrow oriented
upwards) on the bushing;

- lubricate the centering guide and the
piston bolt with engine oil;
- check t he free gliding of the piston
bolt and the piston positioning.
When the connecting rod end is reaching
the necessary temperature (about 250 °C),
proceed to the ra pid of the piston bolt, as
follows: -introduce the centering guide in the
piston; - position the connecting rod i n the
piston;
-press till end the piston bold.
Check if the pi ston bolt is remaining re -
tired as against the piston outer diameter for
each of the connecting rod position in the pis-
ton.
Rings mounting
Mount the rings on the pi ston in the
following sequence: -
oiling ring ( 3);
-s ealing ri ng (2) w ith the mark “TOP”
upwards; -compression ri ng (1) with t he mark
“TOP” upward. The compression and sealing rings are to be
mounted with the slots disposed at 90° against
de bolt’s axle and displaced between them with
180°. The oiling ring is to be mounted with the
slot oriented at 45° against the bolt’s a xle.
The rings slots being adjusted, shall never be
reworked.
Lubricate the pistons with engine oil.
M ount the assemblies “connecting rod-
piston-rings” in the cylinder’s jackets, by means
of the mounting bushing. Mount the sealing gaskets on the cylinder
jackets.
