Did it break?
There are two styles or ways an impeller connects to the shaft of a motor...
threaded
keyed

If not broken, and a threaded style, simply great the impeller onto the shaft. Ensure that you have a new shaft seal installed first.
also... Some threaded shafts utilize an auxiliary screw which is in the middle of the impeller, and it's a BACKWARDS/REVERSE thread!
If not broken and keyed shaft, simply line up the key way, insert the key, then tighten the set screws, once the proper distance/orientation has been set away from the seal plate.
and again... Ensure you have a new shaft seal.

Pentair 011523 pump shaft seal is leaking. How do you remove the impeller and motor?


Separate the plumbing portion of the pump from the seal plate which is attached to the motor. The bolts will be a 9/16 inch hex head, that are visible facing the motor. Remove those bolts. That will then allow you to pull the motor and the seal plate away from the plumbing portion of the pump. Remove the diffuser which is covering the impeller, and then the impeller will need to be unthreaded off of the motors shaft. The motors shaft, will need to be locked. You can do this by removing the Cap on the backside of the motor and you can use whatever tool required to keep the shaft from spinning. Once you are able to lock the shaft, you can read the impeller... Note* some styles will have a screw in the middle of the impeller securing it to the motors shaft? This screw is Backwards thread, not normal thread. If your pump has this screw, need to remove it first, then you will be able to unthread the impeller off of the motors shaft.
once the impeller is removed, you can then remove the two halves of the shaft seal. Very carefully reinsert the new shaft seal into the proper places, just the way they were prior to you removing them.

Reassemble in backwards order as you disassembled everything.
good luck

How can I remove/separate the pump/impeller from the pump Housing?


No. Do not try to unscrew the impeller! If yours is a housing with motor attached just grab the part that has the O-ring and pull it straight out. Though you may need to kind of wiggle it as you pull. Do it over a sink, the liquid in the housing is gray water and can be dumped. The impeller shaft cannot be bent and impeller must be firmly attached to the shaft. If it is bent or loose on the shaft it will not pump properly. If it's solid and straight it should work. Put some petroleum jelly on the O-ring before reassembly. I also like to coat the threads of the filter cap befor screwing it into place.

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.

The bearing needs to be pressed onto the ceramic shaft before inserting the impeller into the housing. Then it just drops in (while trying to hold on to it the best you can to keep it from slamming in.). New bearings didn't come with the new impeller? If not you will have to carefully pry out the old bearing from inside the housing.

Pump disassembly


I removed the impeller on my DW761UQB. The instructions were molded into the plastic pump housing. This is how I DID MINE: Remove motor mount screws. Remove the chopper screw (screw only goes into impeller, not motor shaft). Remove chopper and rotate/remove strainer. Place socket or wrench on impeller tip and place another wrench on rear of motor's plastic fan. Unscrew fan from impeller shaft ( threads are LEFT handed, turn CW). Once fan is 'backed off' of the impeller, CAREFULLY pry the motor/fan from pump housing (impeller is attached to motor shaft via splines). Don't crack the delicate plastic pump housing. Mine was stuck, but separated with moderate force. Now remove the impeller/seals from the pump housing. This worked for MY above mentioned model, I don't know what other models it applies to. I am not a pro.

Frigidaire dishwasher impeller melted! Can't find replacement part!


I have the same problem and after talking to a local service center and doing some online research (remember: Google is your friend) I have discovered this is considered a non-serviceable part and you must buy the entire motor. The impeller comes with the motor. This is probably not the answer you were hoping but is what you have to do. With that said, I plan to JB Weld the ****** back on the motor shaft!

Impeller loose on pump motor shaft


The bore in the impeller is spun out. Mix some JB Weld and apply a liberal amount to the bore of the impeller, install it back on the motor shaft and rotate the shaft a 1/2 turn to distribute the weld before cure. Originally the impeller was a press fit. Don't allow food to get sucked into the pump, lock down and damage to the impeller will occur
