1.1 Replacement of Transfer Motors in NR and NL Sections
(1) Pull out the connector of the motor, loosen two anchor bolts (shown in Fig. G1), and
detach the motor.
(2) Attach the pulley of the detached motor to the new motor, keeping the distance shown
in Fig. G2 and mount the new motor on the main body.
(3) Adjust the tension of the belt by moving the motor mounting plate.
Refer to "3. Set Values for Various Belt Tensions" in Chapter 3 for details.
1.2 Replacement of Transfer Motors in NA, NB, and NC Sections
(1) Remove the two bolts for each motor in the NA, NB, and NC sections and detach the
motors from the main body.
(2) Attach the pulley of the detached motor to the new motor, keeping the distance shown
in Fig. G2 and mount the new motor on the main body.

and loosen the belt.
(2) Remove Bolt B (shown in Fig. G5) and detach the motor unit.
(3) Attach the mechanical lock of the detached motor to the new motor as shown in
Fig. G6 and mount the new motor on the main body.
(4) Adjust the tension of the belt by moving Block A in Fig. G5. (Use a vice.)
Refer to "3. Set Values for Various Belt Tensions" in Chapter 3 for details.
(5) Determine the position of the chute as shown in Fig. G7 while the motor is set in the
"Phase C" mode (Phase C Detection Jig Used) and tighten the mechanical lock
securely.
Tightening Torque: 392 N (40 kgf/cm)
(6) Adjust the sensor so that the limit sensor of the chute is set in the "E/NR" (Light
