19. Stand the pump upright and extract the two bearing
supports, making use of the threaded holes for
removal. ▲ Doing so you will remove the spacers
for axial adjustement too, which should be marked
and separated for a right re-setting while assembling.
20. Remove the ball bearing from its support, taking
away the bull ring.
21. Mark the gears in order to set them rightly while re-
assembling.
22. Withdraw the shafts, with the gears, still inserted.
For this operation we suggest a mechanical lifting
equipment, which can use the threaded holes
arranged on shaft ends.
23. Remove the inside ring of the roller bearing by means
of an extractor. Remove the gear taking care not to
damage the toothing outline.
