Change Procedure for RT Axis Motor Unit
[Reassembly]
8 Attach the pulley
1. Insert the key into the shaft of a new motor.
CAUTION
Smoothly insert the key without stress to
the shaft of motor.
2. Insert the pulley into the shaft of the motor.
3. Put the set shoe deep into the hole of the screws (2-H3x5),
which is to lock the pulley in the keyless position.
4. Apply adhesive (Locktite 242) to the screws (2-H2.5x4)
and (2-H3x5).
5. Refer to the figure, 2.5mm of the gap between shaft and
pully then tighten the screws (2-H2.5x4, 2-H3x5).
6. Apply adhesive (Locktite 242) to the screws (4-C5x12),
and apply the bracket to the motor.
9 Install the motor bracket to the head housing.
1. Apply the RT-axis timing belt to the pulley on the motor side.
2.Lock the bracket to the head housing by
temporarily fastening screws (4-C4x18, W4).
10 Connect the power cable and the encoder cable
to the motor.
