10 Remove the vanes.
Note
1. Be sure to note the orientation and positions of the vanes. The new vanes must be installed in
the same positions.
2. If a vane was broken, then clean any fragments from the pump interior with compressed air.
11 Mount the special tool on side plate "A", then push out the rotor. Support the
shaft area with your hand to avoid dropping the rotor. After removing the rotor,
remove the special tool.
Note: When pushing out the rotor, avoid scratching the rotor shaft and the cylinder.
12 Remove the side plate "A" mounting bolts, and use a plastic hammer to knock
the pin off, and then remove side plate "A".
13 After disassembling to this point, clean each component using a soft cloth
soaked in an organic solvent (chlorine or fluorine based solvent such as Daiflon
S3, by Showa Chemical).

Assembly
1 Insert the rotor into side plate "A".
2 Place the spacer and bearing in side plate "A", then use a bearing punch and
hammer to pound the bearing in.
Note: Place a wood block beneath the shaft to prevent it from being scratched.
3 Mount side plate "A" on the cylinder. After using the knock-pin to position side
plate "A", secure it with the bolts.

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".
