4 Mount the vanes on the rotor. Be sure the vane positions and orientations are
the same as when disassembled.
5 Mount side plate "B" on the cylinder. After using the knock-pin to position side
plate "B", place the spacer and bearing in position, then use a hammer and
bearing punch to pound the bearing in. After the bearing is in, secure the side
plate "B" mounting bolts.
6 Use the bearing punch and hammer again to pound in the bearings at side
plates "A" and "B".

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.
