6.8 Vacuum Pump Motor
Procedure
1 Pull out the vacuum pump. (For this procedure, refer to section 6.6 " 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.
WARNING
• Turn the main power off before performing this procedure.
• Do not touch the vacuum pump immediately after operation
because it may be extremely hot. Allow the pump to cool before
beginning this procedure.

3 Remove parts that hinder motor replacement. These parts include the vacuum
pump, duct, and 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. The bolts that secure the pulley, motor, and vacuum pump should be
tightened finger-tight at this time.
Final tightening should be completed 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 length "L".
7 Reassemble the remaining parts in the reverse order of the disassembly proce-
dure, then connect the wire connectors.
