2.1.2
Assembly of mechanical parts
Proceed with assembly following the reverse order indicated
in par. 2.1.1.
The correct sequence is as follows:
Assemble the red to the piston guide.
Insert the piston guide rod into its seat on the piston guide
(pos.
, Fig. 38) and join the rod to the piston guide by means
of the 4 M6x20 screws (pos.
, Fig. 39).

Lock the piston guide in a vice with the aid of a special tool
and calibrate the screws with a torque wrench (pos.
, Fig. 40)
as indicated in chapter 3.

Insert the con-rod in the piston guide (pos.
, Fig. 36) and
then insert the spindle (pos.
, Fig. 35). Fit on the two Seeger
rings with the special tool (pos.
, Fig. 34).
Assembly has been carried out properly if the
con-rod foot, piston guide and spindle rotate
freely
Separate the caps from the half supports. Proper coupling can
be verified by the numbering on the side (pos.
, Fig. 33).
After having checked casing cleaning, proceed with assembly
of half support-piston guide unit inside casing rods (pos.
,
Fig. 32).
Insertion of the half support-piston guide unit in
the casing must be made with the half bearings
set in the direction in which numbers are visible
from above.
Block the three units with the use of special tool code
27566200 (pos.
, Fig. 31).
Pre-assemble the bearing, PTO side, on the shaft to the end
stroke (pos.
, Fig. 41) and mount the bearing on the opposite
side on the casing (pos.
, Fig. 42).
The bearing in Fig. 42 has a tapered internal
ring. Check that the taper goes from the outside
inwards to allow inserting the bush.

Insert the shaft (pos.
, Fig. 29) until the pre-assembled
bearing is flush with the edge of the casing (pos.
, Fig. 43).
