Maintenance

6-3

1. Using a phillips head screwdriver, remove the two #6 Self-

Tapping Screws (14) on the back of the base that hold the pump

together.

2. Pull apart the three major plastic assemblies in the pump –

the Lower Shield (7), Base (8), and Stator (1) Assemblies.

⁄16" x 1

⁄4" long Alignment Pin (11) aligns the three assemblies

and can be left sitting in the base. The Rotor Assembly (13)

rotates within ball bearings pressed into the Base and Lower

Shield. Two Washers (12) prevent the Rotor Assembly from hitting

the bearings.

3. Replace the Rotor Assembly and Washers with new ones.

4. Reassemble all parts.

a. Slip one washer onto the bottom of the Rotor Shaft. Slip the

bottom of the Rotor Shaft through the bearing pressed into

the Base.

b. Add the second washer onto the top of the Rotor Shaft.

c. Place the Alignment Pin (11) in the mounting hole in the

Base.

d. Slip the Boss (15) in the Stator Assembly over the alignment

pin, until the bottom of the Boss makes contact with the base.

e. Bring the Lower Shield Assembly down, so that the following

four assembly actions occur:

i. The top of the Rotor Shaft fits through the bearing

pressed into the Lower Shield.

ii. The Boss in the Lower Shield fits over the alignment pin.

iii. The slot in the Lower Shield fits over the Clamp Plate.

iv. The bottom of the Lower Shield is flush with the Base.

f. Attach the Base to the Lower Shield with the two #6 Self-

Tapping Screws.
