Pump leaking how do i remove the impeller from the motor shaft

Depending on the pump you have to separate the motor from the housing bust removing the bolts. Once the expelled is exposed, remove the cover and the back end of the motor housing the electrical wiring. You can access the shaft of the motor and hold it in place with a small box wrench. Than spin the expelled off counter clockwise. Replace the melchanical seal and reinstall the impeller. Replace the seal for the housing and reinstall the housing to the motor. Fill the pump with water again and turn the lower back on

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

Removing the impeller requires you lock the shaft as you turn the impeller off counter-clockwise. You will also need to check for an impeller screw in the center of the impeller inlet. If a screw is present they are usually left hand thread. Back out the screw first, then proceed to remove the impeller.

To lock the impeller you will have to remove the motor end cover or a cap covering the shaft end depending on which version your particular motor has. Look at the end opposite the pump and imagine a shaft from one end to the other right in the center.

Once you remove the cover you will see a slot for a screwdriver, a flat for a wrench, a hex hole for a hex key or some combination of these. Lock the shaft and spin off the impeller. Some are so tight you will end up breaking them in the process. Simply replace it and the seal. Be sure the motor shaft is in good enough condition to allow the new seal to work properly. If too much shaft material has rotted away the new seal will leak soon after it is installed; you would need a new motor at that point.

The shaft seal more likely than not needs to be replaced. If your shaft seal has been leaking for any length of time, the bearings could be damaged and this should be replaced. The whisperflow uses a PS1000 shaft seal and is fairly easy to replace (most seals available online or at most swimming pool retail stores). It is best advised not to run the pump until you have had this inspected by a licensed pool technician or have changed out the seal.

1) Make sure breaker/power to pump is off. 2) Remove the six bolts holding the wet end to the seal plate. 3) Remove the diffuser to expose the impeller. 4) Remove the screw in the middle of the impeller by turning clockwise (left hand threads). 5) Remove the dust cap at the rear of the motor and use a wrench to hold the shaft while you remove the impeller by turning counterclockwise. 6) Once the impeller is off, remove the four bolts holding the seal plate to the motor. 7) Press the old seal out of the seal plate and clean it thoroughly. Remove the ceramic part of the seal from the impeller and clean it thoroughly as well. 8) Apply a thin coat of lube (I prefer Magic Lube or Lube Tube) to the seal plate and impeller where the new seal will go. 9) Remove the new PS1000 shaft seal from the box (being careful *NOT* to touch the ceramic or carbon face with your fingers), press the metal part into the seal plate carefully, try not to bend the metal and make sure its completely seated against the seal plate. 10) You can now install the seal plate back onto the motor and secure with four bolts. Press the ceramic part into the impeller, use cardboard or paper between your fingers and the ceramic face. 11) Once you have seated the seal into the impeller, hold the motor shaft and thread the impeller on until snug, then reinstall the stainless screw, remember it is left hand thread so you'll have to turn it counterclockwise. 12) Reinstall the diffuser over the impeller and then install the wet end onto the seal plate using the six bolts, don't overtighten them.
Check the pump for operation and you should be good to go!

sounds like a shaft seal leak..... cut power to pump ... unbolt the motor at the seal plate and pull motor from pump... take electrical cover off back of pump and hold the shaft at the middle (may have to do some digging to find it) of the back of the pump... now youll be able to remove the impeller by spinning it counter clockwise...
make sure you dont go cheap on the seals... and make certain to replace all seals on pump
(diffuser oring, housing gasket, shaft seals, and lid gasket

You will need to disassemble the pump and check the impeller. remove any debris and try turning the impeller by hand. If it does not move or is dragging, you will need to overhaul the pump. Possibly a shaft seal leak has damaged the motor bearing(s). Replace the shaft seal and motor bearings. If the motor is badly deteriorated, you might need to replace the motor. Note... the impeller turns counterclockwise to loosen. you may need special tools to grip and hold the motor shaft and the impeller to prevent damage to the impeller. If the impeller is seized on the shaft from rust, you may have to break it to get it off. reassemble with teflon lubricant on the shaft threads when reinstalling the impeller. This will prevent seizure later.

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.

The pump seal is bad on the unit. This requires disassemble of the pump unit. Remove power to the unit, dissasemble pump housing, remove the impeller from the shaft of the motor by removing the allen screw with an allen wrench. Seperate pump housing from motor remove the old seal replace seal. Lube motor shaft with a little clean oil or wd40 to facilitate easy install thru new seal,reassemble in reverse.

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.
