This can be very tricky at times. Quite often a sharp blow from a hammer on the wrench will work. Sometimes an impact wrench will work too. If that fails, then remove the fan cover from and try holding the motor shaft with channel locks, or vice grips. If it has a fan, you might have to remove it.

How could I remove the impeller to rotate the discharge.

You do not to to remove anything on the pump end to rotate it. Loosen the 4 motor thru-bolts at the end opposite the pump; they pass all the way thru the motor into the pump bracket. Once those are backed out you can spin the pump discharge into the position you need and reinstall the thru-bolts...done!

How do you remove the impeller from the motor shaft?

If the shaft seal has been leaking the impeller stem may have split due to corrosion. This makes it very hard to un thread the impeller. After removing the face plate, try sliding a screwdriver into the front of the motor thru the vents. You should be able to seize the armature from turning by doing this. Then use a large channel lock wrench and try and un screw the impeller CCW. If this doesn't work you have to break the impeller off. See my previous post.

How do I remove the wet end of the pump from the motor section. The pump is a Waterway Spa Pump Executive 56 Frame 4hp Dual Speed 2"

Take the screws off the outer cover fo the wet end. That will expose the impeller.
At the other end of the pump is a small metal cap in the middle. Pry that off with a screwdriver. That reveals the shaft of the motor which has a slot in it. This allows you to hold the shaft still with a large screwdriver.
While someone holds the shaft with a big screwdriver, you rotate the impeller counter clockwise to unscrew it off the motor shaft.
In my case the impeller was so caked onto the shaft with rust that we could not loosen it. We broke the impeller and still could not unscrew it. The screwdriver keeps jumping out of the slot in the shaft.
So the next step was to take the shaft out of the motor. On the far end of the motor are 4 small looking bolt heads. Undo those. They go right through the motor into the 4 legs of the wet end.
Stand the motor up with the wet end up. Pull hard to pull the wet end motor cover off the motor and you will then have the wet end and armature of the motor in your hands. Heavy.
Place some wood into a large vice and then grip the big silver part of the armature in the vice. Then unscrew the impeller.

Need to change out bearings

You will need a 7/16 inch open ended wrench, a bearing puller, a phillips screwriver, a 12" peice of metal electrical conduit, and the bearings.
dismantle wet end of pump down to the impeller. Remove the shaft cap at the back of the motor(small circular cap in back). use 7/16" wrench to hold the shaft under the cap whiile spinning the impeller counter clockwise untill impeller is off. using a 1/4" hex driver remove the 4 through bolt located at the rear of the motor. seperate end caps on motor housing to access the bearings. use puller to remove. use the 3/4" conduit to tap new bearing into place. Reassemble unit.

Make sure you have an o-ring kit for this pump first

I have a Waterways 3.5hp pump that I am trying to remove the impeller from. I can lock the shaft but the impeller will not turn off by hand. Is there a method or tool to assist in turning off the impeller?

Are you holding the motor using the 'flats' on the shaft on the back side?

I have removed lots of impellers - usually I find the center has spun out of the impeller so I use channel locks to remove the hub. All the pumps I take care of are standard thread - might yours be 'backward'?

Try this, get a leather belt and wrap it around the impeller. About a foot from the end, put a stick under the belt. Hold the stick and belt together and try to lever it off that way.

When removing the impeller, how do you hold the shaft still?

Im guessing ...

On the motors I maintain, I remove the back cover. There is a start cap (usually black) on the left side held in place with a clamp. Use a phillips to loosen the clamp. DONT TOUCH ANYTHING that looks like a terminal, and be careful of the centrifical switch on the end of the shaft. Move the cap out of the way. The shaft has two flats that just happen to be 1/2 inch, Put an end wrench on the flats and you j
will have no trouble removing the impeller.

I hope this helps you

How do i remove impellor

The impeller in my 4 HP, 2-speed Waterway Executive High Performance 56 pool & spa pump has a brass coupling embedded in the back side. This coupling can be unscrewed from the motor shaft by keeping the shaft from rotating while turning the impeller in the reverse direction. Then the seal can be tapped out.

Execetive 56 4hp pump

Looking at the face of the pump, the impeller unscrews by turning it counterclockwise. Also, for some strange reason, the 4HP pump gets a 3HP impeller; the rating is embossed, in very small letters, near the center of the impeller. The 3HP impeller part number is: 310-4200.
Be sure to change the seal: US Seal P/n: PS-1000.
