Motor shaft should
not reach the end of
the input bore.
Motor shoulder must
not reach the
clamping hub.
Motor radius must not
reach the clamping
hub.
Motor shaft must be

clamping hub width.
Make sure that the clamping screws of the input split-bore are not tight.
4.
Lower the motor
vertically
onto the gearbox and fix it by tightening the 4 screws of the flange at the
5.
adequate tightening torque (table below):
WARNING!
The motor must be mounted without applying any stress on the input shaft. The motor
centering is done by the gearbox input shaft. That is why it is absolutely necessary to mount
the motor vertically. A wrong mounting can lead to bad running conditions damageable for
the gearbox.
Gradually tighten the 2 clamping hub screws by half rotations until the tightening torque shown in the
6.
table below is reached.
