Op Description
1 Remove the no. 3 screws TCEI 4x20 from the rear balancing block
2 Remove the balancing block
3 Remove the 6 screws TCEI 6x20 from the front flange of the electrospindle
4 Gently remove the worn shaft kit by pulling it from the front flange
5 Insert the new kit in the same way, checking the presence of the ORM0040-10 gasket and
replacing it if it is damaged
6 Screw the 6 screws TCEI 6x20 back again with a flat washer 6 and a drop of loctite 243
thread-locking compound (or equivalent product) on the front flange of the electrospindle.
Tighten with a torque of 10 Nm
7 Reinsert the balancing block so that the mark on it corresponds to those on the shaft
8 Screw the 3 screws TCEI 4x20 with a knurled washer and tighten it with a maximum torque
of 4 Nm
Interpose the thickness spacer between the gear wheel and the encoder reader
BEFORE proceeding with other operations.
If this is not done the magnetic component of the reader could be attracted and
knock against the gear wheel, which could cause potential damage to the
reader.
