3.9 Replacing the Vacuum Pump Motor

Procedure

WARNING

• Be sure to switch off the 200V power supply before

beginning this procedure.

• Do not touch the vacuum pump immediately after

operation as it may be extremely not. Allow the

pump to cool before performing this procedure.

1. Pull out the vacuum pump. (For this procedure, refer to section 3.7 "Replacing the

Vacuum Pump Belt").

2. Use calipers to measure the distance between the vacuum pump pulley and the

motor pulley, and make a note of this measured value.

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.
