Okay...I have to leave for work soon. I'll start breaking it apart tomorrow. I'll go slow and take pictures.
thanks.
thanks.
How to troubleshoot Pump / motor?
- Thread starter doc.mosi
- Start date
Okay...photos to follow.
I've got the intake and return fittings removed. The drain plug out. Some type of plastic C-clip and the basket is off too. Then the housing from the pump it's self.
Now I'm stuck. I don't see any way to take off the impeller itself. No visible screws. Is it pressed on or threaded, if threaded normal or reverse threaded? I don't want to break anything.
Also...it seems to me I should put in new gaskets, o-rings etc... since I have it apart... how do I find these online? Is there some type of kit?
Sorry for all the questions and thanks in advance.
I'll put all the pics in the next post.

Impeller is threaded on the shaft. My Hayward is a normal thread. The slot in the back end of the shaft is so that you can hold the shaft with a screwdriver while you turn the impeller to get it off. When you take off the impeller, be very gentle with the seal behind it. Don't touch where the spring meets the ceramic seal.
Got the impeller off using rubber strap wrench...didn't have to hold the shaft. 
I just busted the first long bolt. @$!#

I think my motor is DOA. I'm gonna try to get the broken long bolts out of the pump housing so I can get it separated and try to save the pump and just replace the motor. Anyone think I can save this motor? I don't know much, but it seems to be dead of neglect.
Any thoughts on a decent replacement motor / pump-motor combo? I don't even know the name of this pump. It's an AO Smith Motor sold with branding of Hayward, the pump doesn't have a name on the plate that I can see.
Here is the back plate.

Here is the motor. See it's all rusted up. You can see the end of the broken long bolt too.

Copper windings?/wires inside all rusted up, well not the wires actually but the flat plates (I don't know the terminology) . The motor part (don't know the part name) that sits inside the copper wires was rusted to the plates, that's why it wouldn't turn.
Even the inside of the motor housing is all rusted up too.

Good job getting it apart. Unfortunately we've hit my limit on pump knowledge. I would also guess that its time for that motor to be done, but wait for a second opinion.
Thanks for the help. It is much appreciated. I'll wait for a couple more people to chime in.
I think I would buy a new pump. I have a pentair whisperflo 1 1/2hp. And its a good quiet little pump. Your pump is all corroded, do you really want to put money and time into a new motor and have something else go wrong.
If you do get a new one,wire it 220v. Save on electricity

I would not call a 1.5 hp Whisperflo a "little" pump, that is actually quite powerful. Likely overkill unless you have a spa or a need to move a lot of water.
I would suggest a small 2 speed, maybe a Dynamo. Others know more about the above ground pumps.

I agree with jbliz, for your pool a 3/4 pentair dynamo 2-speed (model 340194) would be a good choice for your pool size. The dynamo 1 hp 2-speed version or the 1 hp hayward matrix 2-speed are large for you pool, but would also work.
