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.

How to remove a plastic impeller when I've already taken out center bolt.

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.

How do I take it apart

follow this steps and fix it. God bless you
  1. Turn off the pump motor and close the input and output valves.
  2. Loosen the fasteners that secure the tube connecting the pump and motor.
  3. Move the motor away from the pump housing.
  4. Remove fasteners holding the diffuser to the backplate.
  5. Inspect the diffuser and O-ring for wear, replacing as needed.
  6. As needed, remove fasteners attaching the impeller to the shaft. Alternately, the impeller may be screwed on to the end of the shaft.
  7. Remove the impeller and seal from the shaft.
  8. Inspect and replace the impeller and seal.
  9. Reassemble the pump.

J5s is a back pull out. Remove the bolts holding the front casing to the motor. Remove the diffuser. The impeller will either be screwed on. ie the impeller is moulded with a thread, or key wayed .ie a separate metal nut holds down the Noryl impeller and a small piece of "key" steel keeps the impeller on the shaft.
Remove the rear fan cover, and either use a flat screw driver (if there is a slot in the rear of the shaft) or a shifter (if the shaft has a hex) or you may have to prise the fan off. to get a good hold of the shaft.
Hold the rear of the shaft, and with the correct socket undo the hex on the impeller. either the nut or the whole impeller will come off. If just the nut type. Use cable ties to thread down the centre of the impeller to the out side and join. do this in a couple of places.Use these as a lever point to pull off the impeller.
The seal just pulls off. there is two parts stationary and rotating.( 18th may, yourve probably worked it out by now)

How to remove the impeller from a Masport Onga HJ200 pump to access and replace the seal between the pump and the motor.

The impeller is screwed on to the motor shaft; to remove it you need to hold the motor shaft at the fan end so that you can unscrew the impeller - normal right hand thread. Holding the shaft can sometimes be quite difficult so a good suggestion would be to remove the fan cowl along with the fan, this will enable you to secure the shaft with a small pipe wrench or similar. Once you have the impeller removed it will be possible to ascertain what steps need to be taken next - you may need a new shaft sleeve as well as a new mechanical seal assembly.
Good luck,

How do you assemble a Hayward pool pump

If it is completely apart, I am guessing you were replacing the motor? Anyway, motor gets mounted to the mounting plate plate by way of four bolts through the mounting plate into the motor. There is an top and bottom to the mounting plate usually indicated on the plate. Next goes the seal plate, there is a top and a bottom as well, usually indicated on the plate, also there is a **** in the seal plate at the bottom, an opening so if the shaft seal leaks, the water has somewhere to go instead of to your motor to rust it out. There are no bolts for the seal plate, it is held in place by the impeller. You need to get a new shaft seal before you do all this (SPX1600Z2), any compitent pool company should have a bunch of them in stock. Shaft seal is two pieces. The white porcelin piece with a rubber gasket around it goes over the shaft and into the seal plate. It fits snug in the seal plate and does not touch the metal shaft of the motor. The other half of the shaft seal goes on the impeller. The side of the piece of the shaft seal that is all black, with no metal, does not bump up to the impeller, it eventually will touch the white porcelin that is now in the seal plate. That black part of the shaft seal that goes on the impeller is made of carbon and can break somewhat easily so don't bang it on anything. You have to wiggle that part of the shaft seal onto the impeller with a little elbow grease. Make sure it is seated all the way on the impeller. Now you can screw the impeller on the the motor shaft. The motor shaft will want to spin on ya so you have to take the back of the motor off and hold the shaft. Should be a 7/16 or 1/2 inch wrench depending on what motor you got. Snug the impeller up while holding your wrench on the shaft. Doesn't need to be a death grip, the motor will actually tighten the shaft seal more due to the direction that it spins. Now the seal plate should be imobile after you tightened the impeller on. You now put the diffuser on to the seal plate. It also has a top and a bottom usually indicated by some writing. The diffuser has little nobs on it (for lack of a better term) that correspond with female groves that accept the nobs located on the seal plate. It just sits there in those groves, no bolts of screws or anything. Lubricate the gasket on the pump housing before you slide everything back into it. And make sure there isn't any debris that's gonna pinch between the seal plate and the gasket. Slide the whole mechanism into the pump and the seal plate should meet flush with the rest of the pump and tighten to it by way of four bolts (9/16"). When sliding that in there you can take off the pump lid, remove the skimmer basket, reach through the whole and guide the diffuser to the hole. Get those four bolts well snug, but if you tighten too much they will start to recess into the housing which aint a huge deal but you don't really want to go too far down that road. I hope thats all understandable, maybe i went into too much detail but I have taken apart and put back together so many hayward pumps that I have learned all the little things that potentially go wrong......good luck!

Softub about 4 years old - I have a leaking water pump seal - does the impeller need a puller to remove it or can it be levered off ?

Thank you for posting your question here on is threaded onto the motor shaft. Lock the shaft at the end opposite the impeller and turn it off counter clockwise.

1hp whisperflow pump, seal change. How?

Make sure breaker/power to pump is off. Remove the six bolts holding the wet end to the seal plate. Remove the diffuser to expose the impeller. Remove the screw in the middle of the impeller by turning clockwise (left hand threads). 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. Once the impeller is off, remove the four bolts holding the seal plate to the motor. 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. Apply a thin coat of lube to the seal plate and impeller where the new seal will go. 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. 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. 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. Reinstall the diffuser over the impeller and then install the wet end onto the seal plate using the six bolts, don't overtighten them.

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.

I hope this helps, if you have any specific questions, email me at

How to get impeller off hayward power flo sp1525

Once you have the housing apart, 6 screws/nuts I believe, make sure you have the power completely shut off at the breaker. Remove the rear housing on the motor to expose the armature (shaft). Depending on the motor, you will need a 7/16" open end wrench to hold the shaft, be careful not to damage any components, you may have to remove the capacitor or switch to access the shaft. Once the shaft is being held, try to remove the impeller by turning counter-clockwise facing the impeller. If it will not move, you may have to use an impeller removal tool. c85eef7.gifMost pool supply places have them. Be sure to install a new shaft seal, its best to replace the seal anytime you mess with the impeller. Having a good shaft seal will save your motor bearings.

This video helps, although its not the same pump..

I hope this helps....
