Hi, I have a QC 1072 A.O. Smith pool pump motor. How to get the impeller off? Which direction does the impeller spin off? Where to but impeller and seal? Thank you very much Greg


The impeller is just screwed on the shaft. COUNTERCLOCKWISE to remove. Some have a screw in the center attaching it to shaft. This is removed by by turning CLOCKWISE.(reverse threads) Remove back cover and secure shaft with a wrench. There are flats on the shaft to hold it. You might need a large pipe wrench to loosen impeller. Wrap with rag so you don't damage impeller.

MY E90 III SPECK POOL PUMP IS LEAKING BEHIND THE IMPELLER. WE JUST REPLACED THE HOUSING O RING. PLEASE ADVISE A FIX


Thank you for posting your question here on Fixya.com.


Replace the mechanical seal located behind the impeller along the motor shaft. Half is on the impeller and half is in the seal plate.

Where I can buy the A.O Smith 3/4 HP pool pump impeller?


You'll need information from the pump that the AOSmith electric motor is attached to in order to get an impeller or any other pump parts. If there is no nameplate for the pump are there numbers on the impeller you need?

I can't remove the impeller on a 4hp Speck pump...I've worked on several 3/4 to 3 hp pool pumps but this one is a first...also, how is the seal plate attached? maybe I'll figure that out if I'm able to...


If the shaft seal has been leaking for some time the stem on the impeller has likely spit due to corrosion on the motor shaft. This makes it near impossible to un screw the impeller. You can try and isolate the armature of the motor and use a channel lock on the impeller. The only other way to get it off is by breaking it. Use a flat head screwdriver and a hammer and break apart the area around the center of the impeller until you can pry off the everything but the stem. You'll have to remove the ceramic part of the seal and pick out as much of the stem as you can. Then you can get the wetend off the motor and remove the metal cup seal.

How do you remove the impeller from the motor shaft?


If the shaft seal has been leaking the impeller stem may have split due to corrosion. This makes it very hard to un thread the impeller. After removing the face plate, try sliding a screwdriver into the front of the motor thru the vents. You should be able to seize the armature from turning by doing this. Then use a large channel lock wrench and try and un screw the impeller CCW. If this doesn't work you have to break the impeller off. See my previous post.

How do I remove existing motor and replace it with a new one ? Hayward 2.0 hp # SP2615X20 Thank you


Turn off the electric first. Now split the pump in two by removing the large clamp or 4-6 bolts holding the two halves together. (not the 4 bolts holding the motor to seal plate, but the the bolts holding the seal plate to the seal plate housing). Once you remove the clamp or bolts, the motor with seal plate, diffuser, and Impeller can all be pulled back away from the pump. Then disconnect the electrical from the motor and you can pull the motor with the seal plate, and impeller all the way out and work on it. To get to the impeller, you need to remove the diffuser (plastic housing that goes around the impeller) usually by a series of 3 to 6 small screws. To remove the impeller you need to lock the motor and unscrew impeller. Depending on the motor, you remove a cap in the middle of the tail piece and hold with a wrench, or remove a cap that covers the whole end and grab the shaft with a wrench (usually 7/16") by sliding it under the thermal overload switch, or removing the capacitor for even easier access. Once you've locked the shaft, you can just unscrew impeller. If the impeller has a bolt or screw in the middle remove that first. this screw will be reverse thread so make sure you don't turn the wrong way and break or strip. If there is no screw, or after you've removed it, just spin the impeller off (standard thread). If you can't do it by hand and assuming you don't have an impeller wrench, be very careful and use a large pliers, pipe wrench, or strap wrench to loosen it. After that you unbolt the motor from the seal plate, pull the seal plate away from motor (this removes half the seal), and then pop the other half of the seal from the seal plate. Make sure to replace the shaft seal, and use a tiny bit of pool lube on the rubber parts when installing, but keep the white ceramic, and black graphite surfaces 100% free of any dirt, grease, etc while working with them. Installation is pretty much just the reverse. Install half the seal into the seal plate. Install the seal plate onto motor and bolt into place. Install other half of seal onto shaft. Screw impeller onto shaft and install screw (if one was there to start with) in center of impeller (reverse thread). install diffuser over impeller make sure it is centered and doesn't rub the impeller hub. Install new diffuser and valute o-rings. Hookup wiring before re-attaching to rest of pump. Clamp or bolt back together. Pour plenty of water into pot to prime and flip the motor on for a sec or two. Pour some more water. Install pot lid. You should be good to go. Keep in mind there are many different pumps and some variations to the above instructions, but the above should cover most situations. Hope this helps. If you need further assistance post a reply in the comments, and don't hesitate to leave a good thumb rating if you found this helpful. Thanks, and good Luck!

How do I remove the pb460 booster pump in order to install the new one? Does the water have to be turned off from the pool?


You are trying to remove the pump so you can replace the impeller correct?
To remove the impeller you do not need to remove the whole pump. Turn off the electric first. Then just remove the several bolts and separate the back half from the front. Then disconnect the electrical from the motor and your can pull the motor with the seal plate, and impeller all the way out and work on it. To remove the impeller you need to lock the motor and unscrew impeller. Depending on the motor, you remove a cap in the middle of the tailpiece and hold with a wrench, or remove a cap that covers the whole end and grab the shaft with a wrench (usually 7/16") by sliding it under one of the components (not sure exact part off top of my head have to look at it) and then turning impeller. If the impeller has a bolt or screw in the middle remove that first. It should be reverse thread so make sure you don't turn the wrong way and break or strip. If there is no screw, or after you've removed it, just spin the impeller off (it should be counter clockwise standard thread). If you can't do it by hand and assuming you don't have an impeller wrench, be very careful and use a large pliers, pipe wrench, or strap wrench to loosen it. After that you unbolt the motor from the seal plate, pull the seal plate away from motor (this removes half the seal), and then pop the other half of the seal from the seal plate. Make sure replace the shaft seal, and use a tiny bit of pool lube on the rubber parts when installing, but keep the white and black ceramic surfaces 100% free of any dirt, grease, etc while working with them

Im getting a loud buzzing noise when the pump is running


could be an obstruction in the impeller, or the bearings going out. You can split the pump in two be removing the large clamp or 4-6 bolts holding the two halves together. (not the 4 bolts holding the motor to seal plate, but the the bolts holding the seal plate to the seal plate housing. once you remove the clamp or bolts, the motor with seal plate and impeller and diffuser can all be pulled back away from the pump. You need to remove the diffuser (plastic housing that goes around the impeller) usually by a series of 3 to 6 small screws. Now you can easily try and spin the impeller and check for obstructions that might have bound it. If you do not see anything stuck in the impeller, then the noise is likely coming from the motor (probably the bearings) you can replace the motor, or have it rebuilt. if your not gunna rebuild it you can deal with it as long as the noise doesn't bother you and the motor is not getting too hot

I'm replacing the impeller and seal assembly on a Hayward 3/4 HP Max-Flo pump as the original impeller broke at the shaft. I had to remove the impeller thread assy. inside the seal by splitting it as there...


First remove seal plate and mounting plate on motor. The front end bell of the motor is alunimun and is probally corroded, you will need to scrape most of this corrosition off the front of motor and then wire brush this clean. A coat of paint will not hurt at this point or coat or coat in a good pool lubricant to stop corrosion in the future. This calcium will build to the point of warpin seal plate and tweaking impeller shaft and it will quite often crack the seal also. As far as reassembly hand tighten only. If the pump has the motor it came with you have to shut the power off at the breaker and carefully use a 3/8 open end wrench to hold the back of the motir shaft. If the motor has been replaced you will need to check with the manifctuer.

How do you separate the motor from the housing?


Remove the bolts in the back of the plastic strainer housing, that will take the basket assembly off the pump.
The diffuser/ should be visible, this simply pops off with a little twist. The impeller should be now be visible
Remove the metal cap from the back of the pump.
Remove the rubber cap on the back of the motor under the metal case, (may not have one)
You will see a the back of the motor shaft and a slot that a flat head screw driver fits into.
Now is a tricky part that is somewhat dangerous.
You need to hold the impeller and turn that motor shaft with the screwdriver counter clockwise. It's best to hold the impeller with a rag for a better grip. You need to make sure you're using a beefy screwdriver that fits that slot well, or you might slip and jab yourself with the screwdriver.
It is tough to remove. Be careful.
Once the impeller is removed, you will see the seal plate, the bolts for this are on the back out the motor mount plate and can be removed with little effort.
You should now be down to a just a motor.
You may need to buy a replacement seal, as they tend to fall apart once tampered with.
