ROTOR CASE DISASSEMBLY - PUMP TYPE B660 - B680

1. Remove the end cover and untighten the two locking

nuts of the rotors.

2. Untighten the back nuts and remove the rotor case.

3. Unscrew anticlockwise the rotor nuts, interposing a

non metal element between the rotors, making them
stop rolling.

4. Take care of the reference marked on rotors and

shafts (1-2) so that you will set them rightly while re-
assembling.

5. Extract the rotors, taking care you don't damage by

means of metal tools.

6. Untighten the two security screws and remove the

seal flange.
