If the shaft seal has been leaking for some time the stem on the impeller has likely spit due to corrosion on the motor shaft. This makes it near impossible to un screw the impeller. You can try and isolate the armature of the motor and use a channel lock on the impeller. The only other way to get it off is by breaking it. Use a flat head screwdriver and a hammer and break apart the area around the center of the impeller until you can pry off the everything but the stem. You'll have to remove the ceramic part of the seal and pick out as much of the stem as you can. Then you can get the wetend off the motor and remove the metal cup seal.

I have a speck 90 series pump with a broken impeller how do i remove the impeller off the shaft


You'll need to remove the back plate off the motor. Take a pair of channel locks and hold onto the bolt that goes through the motor. With your other hand, unscrew the impeller off the shaft.

Replace the mechanical seal located behind the impeller along the motor shaft. Half is on the impeller and half is in the seal plate.

Im getting a loud buzzing noise when the pump is running


could be an obstruction in the impeller, or the bearings going out. You can split the pump in two be 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 and impeller and diffuser can all be pulled back away from the pump. You need to remove the diffuser (plastic housing that goes around the impeller) usually by a series of 3 to 6 small screws. Now you can easily try and spin the impeller and check for obstructions that might have bound it. If you do not see anything stuck in the impeller, then the noise is likely coming from the motor (probably the bearings) you can replace the motor, or have it rebuilt. if your not gunna rebuild it you can deal with it as long as the noise doesn't bother you and the motor is not getting too hot

How do you separate the motor from the housing?


Remove the bolts in the back of the plastic strainer housing, that will take the basket assembly off the pump.
The diffuser/ should be visible, this simply pops off with a little twist. The impeller should be now be visible
Remove the metal cap from the back of the pump.
Remove the rubber cap on the back of the motor under the metal case, (may not have one)
You will see a the back of the motor shaft and a slot that a flat head screw driver fits into.
Now is a tricky part that is somewhat dangerous.
You need to hold the impeller and turn that motor shaft with the screwdriver counter clockwise. It's best to hold the impeller with a rag for a better grip. You need to make sure you're using a beefy screwdriver that fits that slot well, or you might slip and jab yourself with the screwdriver.
It is tough to remove. Be careful.
Once the impeller is removed, you will see the seal plate, the bolts for this are on the back out the motor mount plate and can be removed with little effort.
You should now be down to a just a motor.
You may need to buy a replacement seal, as they tend to fall apart once tampered with.

Speck Pump Model E90 has very little pressure when vaccuming pool


while I can not personally vouch for this company, they do stock speck parts.

http://www.poolpartsonline.com/m-44-speck.aspx

You will most likely need part # 2920741271 - O-RING (strainer tank) It's the o-ring that sits underneath the strainer lid and is most likely cause of your weak vac pressure. Make sure when you replace it, you use a good silicone based lube. It will help the lid seal better and prevent the o-ring from deteriorating faster if you used a petrol based lubricant.

How do you change a pump seal on a hayward 1hp pool pump


The seal is located behind the impeller. Once you remove the impeller it is fairly obvious how to replace it. Basically, unscrew everything, replace it and put it back together again. There is a decent diagram on page 11 of the Hayward owners manual found here if you need it. http://www.haywardnet.com/products/Manuals/pdfs/Manual113.pdf
