Lock in the rod in correspondence with the two planes with a 36 fork spanner (1, fig. 44) and proceed with
calibration with a torque wrench (1, fig. 45).
Insert the connecting rod in the plunger guide (1, fig. 39) and then insert the spindle (1, fig. 38). Apply the two
shoulder Seeger rings (1, fig. 37).
Assembly has been carried out properly if the connecting rod foot, plunger guide
and spindle rotate freely.
Separate the caps from the half supports. Proper coupling can be verified by the numbering on the side
(1, fig. 40). After having checked casing cleaning, proceed with assembly of half support/plunger guide unit
inside casing rods (1, fig. 33).
Insertion of the half support/plunger guide cunit in the casing must be made with
the half bearings set in the direction in which numbers are visible from above.
