Remove impeller from motor - A.O. Smith SQ1102 Pool Pump Motor

remove the motor from the wet end of the pump remove the cover on the impeller then remove the impeller screw it it normally backwards thread then spin off the impeller this has a regular thread split the motor from the backing plate then remove the seals and replace with new ones then reverse process

look to make sure there is no ***** in the center of the impeller, if so, it loosens to the right. the impeller will come off by turning it to the left (facing the impeller) if you still have trouble with the impeller, search your area for your ''local pool pump motor repair guy'' with free testing.
he should be able to save the impeller and install a new seal for around $20.
remember to prime the pump with water after any repair !

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

Turn off the system at the breaker,
Undo bolts for housing and separate the motor from the pump to access the impeller. Some styles of motors have a screw that is reverse threaded holding the impeller in place, if it has one , remove the screw. Once you have access to the impeller you can use a big pair of channel locks to turn the impeller. Take off the back cover of the motor or remove the plastic or metal cap that is covering the shaft. Use a wrench to hold the back end of the shaft as you unscrew the impeller.

For an impeller really stuck on the motor shaft you need to pull the motor thru-bolts and remove the rotor with the pump still attached from the stator. Lock the rotor in a vice and turn the impeller off with a large set of channel locks or a large strap wrench.

remove the bolts holding the suction side cover on. remove the cover on the end of the motor and use a tool (armature holding tool) to immobilize the motor shaft. remove the center screw (if applicable) in the middle of the impeller by turning clockwise. Spin the impeller off by turning counter-clockwise. If it will not come off, you may need an impeller wrench. Once the impeller is off you can remove the four through bolts and the motor should come right off.

Sounds like maybe your motor bearing are going bad, or have already seized up. When you say "rubber seal" are you referring to the rubber portion of the shaft seal? Either way, 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. If the bearings are seized up then you'll have to replace the motor, or have it rebuilt.

Might be a screw in middle of impeller with reverse thread. If so, remove. Remove back cover of motor, hold center shaft with wrench and unscrew impeller from shaft.

The impeller is threaded onto the motor shaft, take the back cover off and use a wrench to hold the motor shaft, then turn the impeller counter clockwise to remove.

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.
