REPAIR AND MAINTENANCE

INSTRUCTIONS:

To disassemble pump, follow these steps:

1.

Remove handles (9).

2.

Remove body (18).

3.

Remove the volute (19).

4.

Follow these instructions for removing the impeller
(2): Remove the impeller by rotating the impeller
counter-clockwise. It may be necessary to strike
the end of one of the impeller vanes with a wood
block and hammer to start the counter-clockwise
rotation.

5.

If the mechanical shaft seal (8) needs replacing:

a.

With a screwdriver, pry the white seal ring and
its rubber boot out of the back of the impeller.

b.

Remove the pump bracket (rear housing) (13)
by removing the four bolts (4).

c.

To remove the seal assembly (8) from the rear
housing, drive it out from behind.

6.

To replace the seal component in the rear
housing, coat the bore in the housing where the
seal goes with gasket material (Permatex or
equivalent) and press the seal component into the
housing by using an arbor press or drill press.
Use a short piece of pipe that fits on the small
flange of the seal case so that you are not
pressing on the delicate, finely finished, carbon
seal ring. Do not damage the seal face.

7.

To replace the seal component in the impeller
hub, lubricate the outside of the rubber boot with
vegetable oil or soap and press the white ring and
rubber boot into the hub using your two thumbs.
Be certain that the seal ring is all the way down
and even with the back of the impeller so that the
ring does not wobble when the impeller rotates on
the shaft. Do not damage the surface of the white
ring.

8.

Re-assemble the pump in the reverse manner
from the disassembly. Use thread sealant on four
(4) bolts that bolt bracket to pedastal.

To disassemble the bearing pedestal, follow these
steps:

1.

Remove the pump - step 1 through 5b above.

2.

Remove snap ring (43) and tap shaft out with
rubber mallet or use wood block to protect shaft at
impeller end.

3.

Remove bearings with bearing puller or by tapping
shaft off bearings. Use rubber mallet or wood
block to protect shaft.

4.

Clean bearing bores in pedestal and shaft
surfaces and apply Loctite 609 or 620 or
comparable product to shaft bearing surfaces and
install bearings.

5.

Apply the loctite or comparable product to bearing
surfaces in pedestal and install shaft and bearings
in pedestal.

6.

Replace snap ring and re-assemble pump in
reverse manner from disassembly.
