How do you replace doughboy pool pump impeller?

Answer 1

I just had to do this a few days ago and it took some time but was relatively easy.

First - Make sure you have the proper replacement impeller, nothing is worse than getting half way through a job and discovering you have the wrong parts.

You will also need:

Ratchet set or drill driver

Screwdrivers

Set of channel lock or similar pliers

Set of normal pliers

Comfortable chair and some shade

Your beverage of choice

# Make sure your pump is unplugged and turn your filter to backwash. This will keep water from rushing out when you disconnect the pump. Now disconnect the hose coming from the skimmer from where it attaches to the pump. If you hurry and stick the hose in the top of the skimmer basket you won't get very wet. Next, disconnect the hose to the filter where it connects to the pump. Pick up the pump (not by the electrical cord) and take to your workspace. Turn the pump upside-down and unscrew the screws that hold the top cover on the pump. You will now see an electrical motor connected to a water pump assembly. At the back of the motor you will see where the electrical wires are connected. There should be a white, black and green wire. Make a note of which wire is connected where.

# Gently pull the white and black wire from the back of the motor with a wiggling motion. Unscrew the screw connecting the green wire to the back of the motor. Be careful not to strip it, as if your pump is old enough for the impeller to go out the grounding screw will probably be at least a little corroded. # Next look for a silver strap holding the motor down on the base. Unscrew that and you will have the motor and pump free from the housing. # On the front of the water pump there will be two screws holding the basket and casing. Unscrew them and give the basket a gentle twist to remove. # You will now see six screws holding the water pump together. Make a mark with a screw or something else sharp to make sure you can get the halves lined back up the correct way. Unscrew the screws and separate the two halves. (One half of the pump will still be attached to the motor) # The round black plastic disk with the shaft on one side is what you will be replacing. Since you are replacing it the disk is probably disconnected from the shaft. Use a set of pliers to hold on to the remnants of the shaft while using the channel locks to hold the steel shaft between the motor and the pump. Unscrew the impeller shaft, screw the new impeller (not to tight). # Put everything back together in the same order you took it apart. Be careful not to mess up the gasket between the pump halves. # Once you get everything put back together make sure to check for leaks and you should be good to go.
