maintenance. If the power source is out of sight, lock and tag in the open

(off) position to prevent unexpected power application. Failure to do so

WILL result in fatal electrical shock. Only qualified electricians SHOULD

repair this unit. Improper repair WILL result in fatal electrical shock.

after 100 hours of operation.

ADDITIONAL REPAIRS

To replace bearings, shaft seal, or gaskets, follow the instructions

listed below.

Disconnect electrical cord from power supply.

Relieve pressure in system.

Disconnect inlet and outlet lines.

Empty water from pump housing.

Place pump on bench with motor end up and remove brushes

as described in BRUSH REPLACEMENT instructions. If

brushes are to be reused, mark the location from which each

came. Replace brushes in original orientation upon completion

of repair.

Remove the four cap screws holding motor housing and

pump housing together. Motor housing is now free and can

be removed. Take care not to lose commutator bearing finger

spring.

With a screwdriver, pry the rotor-backhead assembly out of the

pump housing.

Remove the impeller by turning counter clockwise (righthand

thread on shaft).

Remove backhead (the bearing is press fit into the backhead).

10. Place backhead on flat surface with impeller side down and

press out shaft seal.

11. Place impeller on flat surface with vane side down and with

screwdriver and hammer break ceramic seal ring into several

pieces and remove. Next, remove rubber seal ring cup from

impeller.

12. Remove bearing from armature shaft (press-fit on shaft). (Impeller

side bearing is the only serviceable bearing).

13. Inspect the armature commutator bars. The environment in which

the unit has been operating will have influence on the condition

of the commutator. Airborne dust an dirt will accelerate wear. A

rough or scarred appearance may dictate having commutator

reconditioned before reassembly.

14. To reassemble, install new bearing on the shaft. Always press

against the inner race to prevent bearing damage. Make sure

bearing is tight against the shaft shoulders.

15. Place rubber water slinger flat inside seal cavity in impeller side of

backhead. Press shaft seal into backhead. When pressing shaft seal

into place, apply force to the cup flange. Avoid touching the polished

seal surface; oil or scratches on this surface may cause premature

failure of the seal.

16. Press ceramic side of seal into impeller, ceramic side out. Avoid

touching ceramic with hands as oil may cause premature failure of

the seal. Wipe oil off both sides of seal with a soft, lint-free cloth.

17. Reassemble unit in reverse order, beginning with Step 9. Use

caution when sliding rotor shaft through backhead and water slinger

not to pinch or damage water slinger.

18. After reassembly check shaft for free rotation with screwdriver in fan

through air exit openings.
