- Apply the two pins Ø5 on the reduction gearbox (Fig. 26,
pos. ). Pre-assemble the bearing on the pinion and
insert it fully into its seat in the reduction gearbox with a
hammer (Fig. 27).
The bearings and crown wheel can be mounted cold. The
press fitting operation can be facilitated by heating the
involved parts to a temperature between 120°C - 150°C (250°F
- 300°F), ensuring that the ring nuts fit fully into their seats.
- Insert the O-ring into the reduction gearbox seat (Fig. 28).
- Fit the cover onto the pinion bearing using two M8 grub
screws or screws to hold it in position during assembly
(Fig. 29, pos. ).
- Mount the reduction gearbox cover by pressing a buffer
on the face of the cover or using the special tool code
27517400 (Fig. 30).
- Make this easier by simultaneously screwing in some fixing
screws (Fig. 29, pos. ).

screws and calibrate the screws with a torque wrench
(Fig. 31) as indicated in chapter 3.
