5.2.8.2 Impeller Shaft Installation
1. If the impeller shaft coupling is removed from the impeller motor install
the coupling on the motor shaft against the front face of the motor.
Tighten the retaining setscrew (using a 3/32-inch Allen wrench).
2. Slide the impeller shaft into the coupling until it bottoms against the
end of the motor shaft. Tighten the retaining setscrew snugly (using
a 3/32-inch Allen wrench), about ¼ turn past the first resistance.
3. Mount the impeller motor on the back of the panel with the retaining
screws and washers.
4. Fasten the impeller motor grounding terminal (with pump motor
grounding terminal) on the back of the panel with the retaining
screw and serrated lockwasher.
5. Remount the panel in the mounting enclosure.
6. Reattach the sample and reagent tubing to the inlet of the metering pump.
7. Apply a small quantity of silicone grease to the O-ring and
impeller shaft.
8. Reinstall the seal adapter, grit guard, cell sealing O-ring, impeller,
and cell body and cell retaining screws, as described in paragraph
5.2.6, Impeller Shaft Seal Replacement - Installation of Shaft Seal.
5.2.9 Pump motor removal and replacement
1. Remove the panel assembly from the mounting enclosure. Refer
to paragraph 5.2.1, Wetside Panel Removal and Replacement.
2. Remove the pump rotor and thrust washer from the panel assembly.
Refer to paragraph 5.2.1, Pump Rotor, Rollers, and Thrust Washer
Removal and Replacement.
3.
Disconnect the motor ground lead from the back of the panel.
4. Remove the two screws that mount the motor from the front of the panel.
5. Gently slide the motor out from the back of the panel. The motor
shaft has a sliding fit inside the ball bearing in the pump hub. If it
binds while trying to slide it out, check the exposed portion of the
shaft for dirt or scratches that may cause binding. Clean off the
dirt or carefully remove scratches with a fine file. The shaft can be
damaged by excessive filing.
