How do you remove the impeller from the pump shaft on my USQ1102 pump? Tom Marchand

the impeller is screwed on like a bottle cap. On a sq flange motor, it is harder to do. the armature spins when you try to remove the impeller. you can try to use needle nose vise grips to keep it from spinning by gripping the shaft from underneath (between pump and motor) then try unscrewing the impeller. If this does not work, You will have to remove the armature. their are 4 thru bolts that can be removed from the back of the motor. they are each about a foot long. WD40 the place where the connect to the pump housing or you may break the housing. When removed, you can tap the rear of the armature with a hammer and chisel. when it pops free, remove the armature from the motor. you now have in your hand, the pump still attached to the armature. you can place the armature in a vise, (make sure you do not damage it) then use channel lock pliers to unscrew the impeller. The impeller may still break. Or you can try and place a wedge in the pump housing to keep the impeller from moving and turn the armature. good luck, it is not an easy job.

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

WELL HERE YA GO. I TAKE THE MOTOR COMPLETELY APART , TAKE THE ROTOR AND PLACE IT IN THE VICE , THAN I TAKE A BIG PAIR OF CAHNEL LOCK PLIERS AND BY GRIPPING THE OUT SIDE EDGE OF THE IMPELLER, TURN TO THE LEFT ! IT IN MOST CASES COMES OFF WITH EASE .. IF YOU DONT HAVE THE TOOLS, GET THE MOTOR DOWN TO THE ROTOR AND SEARCH YOUR AREA FOR YOUR LOCAL POOL PUMP MOTOR REPAIR GUY WITH FREE TESTING .. AND I'M SURE HE WILL TAKE IT OFF FOR FREE FOR YA .. I'TS BEST OFF TO HAVE HIM DO IT, BECAUSE IF YOU BREAK THE IMPELLER , IT CAN COST YOU BIG ! .. IF I WAS OF HELP HIT THAT YES BUTTON .. THANKS ..JAY... THE POOL PUMP REPAIR GUY IN LONGWOOD FLORIDA .. HOME OF THE BARK'N GOOD DEAL

Can you send me a picture of the parts you need? If so, sned it to [email protected] or use the contact us feature found at www.arrowmotor.net.

I have never taken this pump apart.
If I were in your position and I could move the impellar 1/8 turn, the next thing that I would do is carefully loosen the nut on the end of the shaft being careful that nothing else disassembles. Once this nut is loose say 2 turns, try the impellar again watching what is moving. It seems that the nut may have to be removed.
Also, I'm not sure which way the nut of the impellar rotates to remove, but you seem to have that under control since you have it moving already.

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.

If it's a separate shaft, it requires a puller tool, but first you have to remove a nut that holds the impeller to the shaft. If the shaft is part of the impeller, meaning that it is a one piece fabrication, then there is nothing you can do about it. You haven't even stated where does this impeller come from, a washing machine, a water pump, etc.

First, separate motor and pump. Remove back cover of motor. Drive shaft of motor either has a slot on end for a large screwdriver or a flat on it for a wrench.(usually 7/16) Hold shaft and unscrew impeller.

the drive shaft goes down through the water pump impeller and I suspect that the problem will be in the pump
the impeller is rubber and if run dry will melt the rubber into the housing and bind up the shaft
Brute force is a last resort so get all the information you can from a service dealer mechanic

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.
