No sign of any seal leaks. It looks like the front bearing is bronze, and
is just worn out (motor shaft wobbles when I turn the rotor by hand).

I found the slot in the rear of the shaft behind the cap, but the impeller
is on too tight. I finally got the motor front housing off and the rotor
out, so I can clamp the rotor in a vice. I still can't budge the impeller.
With the scroll around it, I can't get anything on it to unscrew it (and I
AM turning it in the right direction) and it's too tight to reach in and
turn by hand. About the only thing I can think of is to make up some sort
of clamp out of aluminum plate, that clamps onto the impeller outer
diameter, and then turn it with a wrench of some kind. Lot of work to just
try and salvage the pump. I've also tried a strap wrench through the outlet
hole, but there wasn't quite enough room. Frustrating.

I picked up a couple of Waterway spa pumps (they say 5 hp on them, one is
two-speed). The pumps are fine, but the motor front bearings seem to be
worn out. I can't get the pumps off the motor shaft to replace the
bearings, but I can cut up the pumps and salvage the motors that way.
These
are A. O. Smith, 220 V, 1 ph, 12 amp, 3450 rpm, capacitor start motors
(metal content).

Some questions.

Any idea what I could get for these on Ebay "as is".

What would the motors alone be worth if I replace the bearings?

Would these motors be good as compressor motors?

Any idea how to get the pump impellers off the shaft, so that I can
rebuild
them and sell them as complete units? The impeller seems to be pressed or
epoxyed onto the shaft, since there is no sign of a setscrew or key. No
exposed shaft inside the pump to apply a puller. I've tried levering off
one the pumps between the front housing and back of the pump, but nothing
moves.

Any advice would be appreciated. Thanks.


Take the cap off the back motor and there will be a slot or flats (if
not there then it will be on the front of the shaft between the
impeller and motor) to hold the shaft so that the impeller will thread
off.

When the shaft seal leaks it screws up the front bearing. They can be
a major pain to get off. The two speed is for circulation and jets,
the other is a booster pump and is probably in better condition.

Might be hard selling used pool pumps that big. Their more likely to
be from a commercial application or rich folk.
