manipulated more easily:

using appropriate equipment.

proceed with caution to remove the reduction
gear motor. It is recommended to wear gloves.
Installing the traction motor
- To install the traction motor, proceed in the reverse
order as for removal.
- Replace the O-ring (5) and grease it before refitting
the motor (1) in the reduction gear (8).
- Check the tightening torque of all the joints and con-
nections of the motor (see section 2).
CAUTION
- To prevent a short-circuit, it is important to
clamp the 3 terminals U, V, W of the traction
motor supply cables (tightening torque
9 Nm ).
- It is always possible to use an open-end
wrench to hold them while tightening.
- Make sure that all the fixtures are tightened at the
correct torque of 9.5 Nm
- Check the electrohydraulic brake air gap setting (see
