Insert the bush locking flanges into the conical bushes
(pos. , Fig. 78).
Apply a sufficiently long (35-40 mm) M16 screw to the M16
hole on the bend shaft and screw it in, until the flange is
touching the bush (pos. , Fig. 79). Do not tighten the screw.
Repeat the operation on the other side.

(pos. , Fig. 40).
Insert the upper half-bearings between the con-rods and the
bend shaft (pos. , Fig. 80).
For proper assembly of the half-bearings, ensure
that the reference tab on the half-bearings are
positioned in their housing on the half support
(pos. , Fig. 81).
Apply the lower half-bearings to the caps (pos. , Fig. 82)
ensuring that the half-bearing reference notches are
positioned in their housing on the cap (pos. , Fig. 82).
Fasten the caps to the half supports by means of M12x1.25x87
Fig. 78
screws (pos. , Fig. 83).
Calibrate the screws with a torque wrench as indicated in
chapter 3 bringing the screws to tightening torque at the
same time.
Note the correct assembly direction of the caps.
Numbering must be turned upward.
