7 Place the liners and bearing retainers on side plates "A" and "B".
Note: Even if the number of liners and their combinations are assembled in the same manner as
when disassembled, there may be some play when the shaft rotates.
The number of liners and the liner thickness should therefore be adjusted as necessary to
eliminate this play.
8 Verify that there is no contact between the rotor and the side plates when the
rotor is rotated while pushing and pulling the rotor shaft.
9 Complete the vacuum pump reassembly by reversing steps 1 to 6 of the disas-
sembly procedure, then reconnect the cable connectors.

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.
