10 Remove the vanes.

Notes:

1. Be sure to note the orientation and positions of the vanes, as the new vanes must be

installed in the same manner.

2. If a broken vane exists, air blow the pump interior to remove any fragments.

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, use care to 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, 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 Kurorosen or

Daifuron S3).

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".
