Disassembly
1) If your pump has a retaining ring on the cap, use the retaining ring pliers to remove the
ring. Supporting the pump under the arbor press and using the ram to apply pressure aids in
removal of the retaining ring, and can help prevent it from flying off.
If your pump has a sticker on the cap and no retaining ring, remove the sticker. You will see
two small holes on the outer edge and one larger hole in the center. Support the pump in a
vise, and using the spanner wrench in the two outer holes, unscrew the cap counterclockwise.
2) Remove the stainless cap (retaining ring version) or stainless cover (screw-on cap version),
and then remove the o-ring underneath. Sometimes the cap/cover is too difficult to remove by
hand, and a tiny, flathead screwdriver can help to pry the cap free from the o-ring underneath.
3) Flip the pump over and support it on its rim. It should be held several inches above the
work surface of the arbor press, otherwise it will be difficult to fully press the rotor out. Make
sure nothing is obstructing the graphite flanges and rotor from being pressed out. The shaft
of the pump should be positioned directly inline with the ram of the press.
4) Press down on the pump rotor with the arbor press until you hit the bearing. Then you will
need to press the rotor the rest of the way out with the small metal rod (material #3). At this
point the rotor, front flange, vanes, and pins should be out of the pump. Sometimes additional
parts will have come out, but the proceeding steps are still required.
5) Next, you will need to remove the ball bearing. If you have a bearing puller, use it to
remove the ball bearing. If not, insert a slightly tapered pin (one end slightly larger than
11mm and one end slightly smaller) from the inside of the pump, through the seal, and into
the bearing. Support the pump with the bearing facing down, but make sure the bearing is not
obstructed from being pushed out. Then press the bearing out with the tapered pin from the
inside.
