How to remove impeller from motor to replace. I 've removed all the bolts but can't remove the impeller from the shaft.

To remove the impeller you will twist the impeller off in a counter clockwise motion. However, the impeller cannot be freed from the motor shaft without first securing the motor shaft.

Most pump motors have a circular plastic cap in the center of the motor. Removing this cap will give you access to the motor shaft. Some shafts have a slot for a screwdriver to hold the shaft while you unscrew the impeller or in some cases the impeller bolt. Some are reverse thread so try both directions if it won't loosen.Hope this helps.

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

The bearings are in the motor itself. You can separate the motor from the wet end by removing the wet end. You can then remove the cap or cover on the back of the motor to expose the shaft. It may be a hex tool, a slotted tool, or 7/16 wrench that you'll need to hold the shaft while you spin off the impeller (you may need an impeller tool as well).

Once the impeller is off, you can remove the seal plate and the motor will be isolated. You can then remove the through bolts and proceed to replacing the bearings. You will most likely need to replace the shaft seal as well.

There are many tricks associated with doing this invasive of repair. I cannot cover every scenario you might encounter. Personally, when the bearings go bad, I usually replace the motor as it's usually a number of years old and all of the components will start to go bad including the windings. These motors run at high temperature and unless you've encountered a bad shaft seal that allowed water into the bearings, it may be worth replacing the entire motor. Just my thoughts. Hope it helps a little.

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!

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!

Disconnect all power. Remove the six bolts holding the seal plate to the wet end. Remove the two small allen screws to remove the diffuser. Remove the dust cap from the end of the motor and secure the shaft from moving. If installed, remove the Phillips head screw in the center of the impeller by turning clockwise (left hand threads). You can now remove the impeller by turning counter clockwise, note that you may need an impeller wrench to remove it and a specific tool to hold the shaft while you remove the impeller. Once the impeller is off you can remove the four bolts that hold the motor to the seal plate. This process just needs to be reversed to re-install but you will need a new shaft seal (PS-1000).

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 screws on the motor shaft. First replace the through bolts in the motor. These are the long bolts, they will just cause headachs. On the back of the motor their will be a place to hold the shaft from turning, If you hold the shaft the impeller just unscrews. If you look in the center of the impeller it may have a set screw holding it to the shaft. If you have one of these it will be a left hand screw. Then you will need to break the impeller free as the brass that holds the impeller on will stick to the stainless steel of the shaft. Don't let how tight this is fool you when you put this back together it just goes on hand tight. Good luck

It is a good idea to replace the tank o-ring when taking to pump apart, but if the o-rings are in good condition, just apply a light coat of lube and reuse them.

This is a general guide for replacing a seal, if you have trouble removing the impeller, you may need an impeller wrench and a tool to hold the motor shaft.
