The first thing you will need to do is remove the four 9/16″ bolts that hold the wet end / volute of your pump to the motor assembly. You will need to use either a crescent wrench, socket or even an open end wrench. You will want to remove the top bolts first and then you can remove the lower bolts.
You will want to turn the 9/16″ bolts to the left which is counter clockwise until they thread all the way out of the pump housing, you will want to to this with the two top bolts.
Hayward Super Pump Impeller Removal [Step Two]
Once you have removed the top two 9/16″ bolts that hold the Hayward Super Pump housing to the motor assembly you will have to remove the two lower 9/16″ bolts. You will not be able to use a wrench here as there is no space to do so. What you will want to do is use a 9/16″ socket with a 4″ socket extension to remove the bottom bolts. You will want to also turn these bolts to the left which is counter clockwise.
If you do not have a 4″ extension as shown you can also use a bigger extension like a 6″ or 12″ extension, They might be longer but will also work to remove the pump housing bolts.
Hayward Super Pump Impeller Removal [Step Three]
Once you have removed the four bolts from around the pump housing / wet end of the pump you will now be able to remove the motor assembly from the volute / wet end of the pump. You will now want to place the pump housing off to the side so you can work on removing the impeller from the motor shaft.
There may be a small amount of water that drains from the pump housing when you remove the motor assembly. Always be sure to remove the pump housing either outside or in a place that has drainage.
Hayward Super Pump Impeller Removal [Step Four]
Now that you have removed the wet end / pump housing of the pump you will see the impeller. This is the time to get your strap wrench out and also notice the “top” imprinted into the seal assembly housing. You will need to put the pump back together the same way you took it apart, so notice the top that is marked on the top.
Now if you were just going to try to remove the impeller as this point, you would never be able to because the motor shaft would continue to spin as you spun the impeller.
Hayward Super Pump Impeller Removal [Step Five]
You will need to be able to hold back on the motor shaft as you spin the impeller. You can do so by holding onto the motor shaft with either a pair of channel lock pliers or a 1/2″ wrench. But first you will have to remove the rear motor access cover so you can gain access to the back of the motor shaft.
You will want to loosen and remove the two 5/16″ bolts that hold the back cover onto the motor. Once you do so you will be able to see the motor shaft, capacitor and the motor switch.
Hayward Super Pump Impeller Removal [Step Six]
Once you loosen the two bolts you can take the cover all of the way off so you have room to work. Move the cover back and forth and side to side to gain access to the back of the motor shaft. You might even have to pull on the cover a bit of you motor is older.
If the rear cover of your motor is stuck on, you can use a hammer and a Flathead screwdriver to tap on the edge of the cover to help remove it from the motor casing. Sometimes older motors can develop some surface rust between the cover and the motor casing resulting in a hard to remove rear motor cover.
Hayward Super Pump Impeller Removal [Step Seven]
When the rear cover has been removed from the back of your Hayward Super Pump motor you will be able to see the motor switch. Right behind the motor switch you will see the motor shaft. On the motor shaft of this AO Smith motor you will see two flat spots that you can either grab with a pair of channel locks or you can use a 1/2″ wrench to also grab that shaft.
You will want to grab the motor shaft and also turn the impeller counterclockwise at the same time. This may take some strength to remove the impeller. You could also use a strap wrench to turn the impeller.
Hayward Super Pump Impeller Removal [Step Eight]
If you do not have a strap wrench you can also use your hands to remove the impeller from the motor shaft. You will need to hold back on the rear of the shaft like we explained in the above paragraph, but if you are strong enough you will be able to spin off the impeller by hand.
You will want to turn the impeller to the left which is counterclockwise until the impeller has be removed from the motor shaft.
Hayward Super Pump Impeller Removal [Step Nine]
Once you have “spun off” the impeller you will see two parts of the mechanical seal. One part of the mechanical seal is on the impeller and the other part is on the seal assembly.
Once you have removed the impeller you then can change the mechanical seal. Make sure the impeller is also free of debris before reinstalling it back on to the motor shaft. Once you replace the seal, you can spin it back onto the shaft holding the rear of the motor shaft and by turning the impeller to the right which is clockwise and will thread the impeller onto the shaft.
