Insert the con-rod in the piston guide (pos. , Fig. 39) and
then insert the spindle (pos. , Fig. 38). Apply the two
shoulder Seeger rings (pos. , Fig. 37).
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. 40).
After having checked casing cleaning, proceed with assembly
of half support-piston guide unit inside casing rods (pos. ,
Fig. 33).
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. 32).
Pre-assemble the ring inside the bend shaft bearings (on both
sides of the shaft as far as possible) using special tool code
27604700 (pos. , Fig. 45) (pos. , Fig. 46).
The inner and outer rings of the bearings must
be reassembled keeping the same coupling with
which they were disassembled.
Insert the shaft from the PTO side, taking care not to hit the
previously assembled con-rod shanks (pos. , Fig. 47) and
(pos. , Fig. 48).
The bend shaft must always be assembled with
the PTO on the opposite side with respect to the
G1/2" holes for the oil discharge plugs on the
Fig. 45
pump casing (pos. , Fig. 50).
Fully insert the shaft in the casing (pos. , Fig. 49 and Fig. 50).
