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".
