How do I remove impeller from motor? Is there bolt or does it screw off? It appears head of bolt is sheared off.

The impellar spins off counterclockwise on most pumps. The hard parts are holding the motor shaft from rotating and finding a way to grip the impellar.

I believe that on the back of the motor shaft, there are either wrench flats or a screwdriver slot.
Use the appropriate tool to hold the shaft from rotating and grip the impellar with your hands or a strap wrench or other device and unscrew it.

My Pentair WF-26 1.5 HP just started emitting a loud "whine" detectable above the regular pump noise. Looking through the window into the debris basket the water also looks more frothy than...

The loud "whine" you hear, does it sound like its a metal kind of "whine"? There are a couple of things it could be. Your impellar may have debris caught in it and to properly check and clean the impellar you will need to open up the pump and remove the diffuser and check/clean as needed. You can sometimes remove the basket and try to feel your way with a couple of fingers to the impellar but your only able to reach 10% of it. Whisperflo is an outstanding pump but very notorious for debris getting stuck in the impellar and the impellar breaking easily because it is plastic. If you have ran the pump without prime/no circulation you can easily have caused heat damage to the impellar. The other thing to check is the motor. Although it is only 2 1/2 years old the motor still could be going out. The bearings are the top noise makers when a motor is going bad. You will still have normal suction/circulation it will just be really loud when the motor runs each day.

I hope this helped. Please don't hesitate to submit any further questions you may have. I would be glad to help.

Ihave a hayward 1hp inground pool pump and can not get the impellar off

you will need to hold the motor shaft at the back of the motor with either a 7/16 open end wrench, or either armature tool. You can then use a closed face impeller wrench to remove it. Make sure if there is a screw in the center of the impeller to remove it by turning clockwise.

Motor humming will not turn

You can undo the bolts that are holding the motor to the pump. That will let you spin the impellar of the pump .. Please withdraw it slowly and observe how the extra pieces fall out because if you get them in wrong the pump will not work correctly, While you have it apart , try and spin the impellar and switch the motor on , seeing if it will run if you hand start it .. if it will not run , then you probably need a new motor .. Most pool shops can test the motor for you to confirm that .

Have you used pool 'O' ring grease on all 'O'rings - tipped water from bucket on all pipe joins on suction side to see if blows bubbles?

Jandy jhp .75 hums when you turn it on does not pump

It sounds as if motor is spinning and pump is free so the impellar must not be attached to the motor shaft. There is a set screw on the impellar to hold it to shaft or the pump impellar could be cracked. Only way to tell is take the impellar housing off.

what kind of motor or pump? Hayward, pac flo?

Hi George It's your impellar or bearings you need some tools for the bearings but if it is impellar you can do this I would suggest you just take it in and rebuild hole thing as you will be better off in the long run.
