Apply two M16 threaded pins to the end of the crankshaft
and, while keeping it raised (pos. , Fig. 72), insert the bearing
support cover complete with bearing and O-ring (pos. ,

the other side
Fasten the bearing support covers with 6+6 x M10x30 screws
(pos. , Fig. 74).
Calibrate the screws with a torque wrench as indicated in
chapter 3.
Partly insert the two pressure bushes, keeping the bend
shaft lifted up by means of the previously-mounted M16 pin
(pos. , Fig. 75).
Insert the pressure bush completely onto the bend shaft
Fig. 72
(pos. , Fig. 76 and Fig. 77) using an extractor hammer and a

The pressure bush must be inserted dry (no
lubricant oils).

Insert the bush until the outside (conical) surface perfectly
couples with the inside of the bearing. During insertion, make
sure that the bearing stays in contact with the bend shaft
