6. Adjust the tension of the new belt. If the belt tension is outside the prescribed range, move the motor position in 0.1 mm increments to adjust the "L" dimension. 7. Reassemble the remaining parts in the rev…
3. Remove all parts which hinder the motor replacement work. These parts include
the vacuum pump, duct, the belt.
4. Remove the motor, then remove the pulley from the motor.
5. Mount the pulley on the new motor, then set the motor and vacuum pump on the
base. Bolts which secure the pulley, motor, and vacuum pump should only be
partially tightened at this time.
Final tightening should be performed after adjusting the pulley deviation and the
distance between the vacuum pump pulley and motor pulley (distance noted at
step 2). The pulley deviation should be 0.3 mm or less.

6. Adjust the tension of the new belt. If the belt tension is outside the prescribed
range, move the motor position in 0.1 mm increments to adjust the "L" dimension.
7. Reassemble the remaining parts in the reverse order of the disassembly procedure,
then connect the harness connectors.

3.10 Replacing the Vacuum Hoses
Procedure
WARNING
• Be sure to switch off the 200V power supply before
beginning this procedure.
• The spring force may cause the cam axis to rotate if
the cam axis is positioned anywhere other than the
origin position (0 degrees). Always use extreme
care when working inside the machine, as this is a
dangerous area.
1. Detach all nozzle holders.
2. Move the placing head where a vacuum hose is to be replaced to ST9, fix the cam
angle at 180 degrees, then replace the vacuum hose between the head manifold
and the nozzle shaft assembly.
3. Connect the vacuum hose to joint 4 for CP-742ME/742E, or joint 3 for CP-732E as
shown in the figure below.
