Lock the piston guide in a vice with the aid of a special tool
and calibrate the screws with a torque wrench (pos. , Fig. 50)
as indicated in chapter 3.
Insert the con-rod in the piston guide (pos. , Fig. 45) and
then insert the spindle (pos. , Fig. 44). Fit on the two Seeger
rings with the special tool (pos. , Fig. 43).
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. 42).
After having checked casing cleaning, proceed with assembly
of half support-piston guide unit inside casing rods (pos. ,
Fig. 41).
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. 40).
Insert the bend shaft through the rear opening of the casing
and lay it on the bottom.
The bend shaft must be inserted into the casing
so that the teeth on the ring gears are oriented as
shown in Fig. 51.

Pre-assemble the PTO shaft:
Onto the PTO shaft, slip on the 2 internal rings of the bearings
(one per side) (pos. , Fig. 52).

From one side of the casing, insert the bearing lubrication
bush (pos. , Fig. 53) and an external bearing ring (pos. ,
Fig. 54) using a buffer and an extractor hammer.

The internal and external bearing rings must
be reassembled in exactly the same order and
pairings in which they were dismantled.
