3. Loosen the motor belt adjuster bolt.
4. Disconnect wires to the motor junction box. See Figure 9-8.
5. Remove motor from motor bracket.
6. If reusing motor pulley, remove from faulty motor and install on
new motor.
7. Adjust the tension of the motor belt by using the belt adjuster bolt
located below the motor. The motor bracket attachment bolts must
be loosened before adjustments can be made. The encoder fasteners
must be loose and the encoder pushed away from the motor belt.
The motor belt should deflect 3 mm (1/8 in.) with a 1.4 kg (3 lb)
force applied perpendicular against the belt. Tighten the motor
bracket fastening bolts and recheck the belt tension. Readjust belt
tension if necessary.
8. Move the encoder so that the pulley teeth engage the motor belt
and the pulley turns when the belt moves. It should deflect the
motor belt 1mm (.03in). Tighten the encoder fasteners.
