5. Opposite side of the motor: to lock the system, hold the locking tool in the coupling and block it
from rotation (see below).
6. To eliminate the system backlash, apply approximately twice the application preload torque on the
bevel gearbox female hex with a torque wrench. Once this torque is reached, reduce the torque
slowly to a value near 0 and apply the application preload torque Tp.
7. While holding the preload torque, tighten the coupling screws one after the other in several passes
until the tightening torque T
