(pos. , Fig. 31).
Insert the upper half-bearings between the con-rods and the
shaft (pos. , Fig. 56).
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. 57).
Apply the lower half-bearings to the caps (pos. , Fig. 58)
ensuring that the half-bearing reference notches are
positioned in their housing on the cap (pos. , Fig. 58).
Fasten the caps to the half supports by means of M12x1.25x87
screws (pos. , Fig. 59).
Note the correct assembly direction of the caps.
Numbering must be turned upward.
Calibrate the screws with a torque wrench as indicated in chapter 3,
bringing the screws to tightening torque at the same time.
