i got the shaft! off that is! i rigged up a pump impeller puller from wood and bolts and it did the trick. wanted to share pics in case anyone else has a similiar problem with a stuck impeller. here goes!
first off this is the motor off the mobile maid with the wash impeller very much stuck on the shaft.
cut the white plastic pump guard strainer off with my dremel so i could see what the impeller looks like. i may be able to find a new strainer when i go to modern parts house in parma this week. if not oh well!
i then put impeller between 2 boards to support it. that's when i got the idea to build a pump impeller puller.
it has a small round base and fans out near the top, like an ice cream cone actually. i decided to mount it on a board with a hole in it to support and hold it without putting pressure on the impeller blades.
i was sure they would break under the pressure of pushing that shaft off.
so a trip down home depot's lumber and hardware aisle and 12 bucks later i was in business!
impeller puller out of 5/16 threaded rod that i bought and cut into 12 inch sections. i used fender washers and nuts to anchor it down into it's little "impeller puller tower"
2 firing strips on the top of the threaded rod to act as the "push" behind the impeller removal. i secured them with nuts and fender washers and drilled a 5/16 hole thru the center directly above the center of the motor shaft on the impeller.
you follow me here?
i soaked it all again in pb blaster
the idea is when i turn a nut on the center rod it will tighten up on the rod against the firing strips screwing the rod downward. the rod touches a bolt i screwed into the motor shaft. i did not use origional bolt that holds impeller on but bought a longer one.
as i continued to turn the nut the rod was screwed down and it literally pushed the shaft off the impeller which was tightly lodged in it's wooden cradle. yet the impeller blades were toughing nothing!
after impeller was lifted off shaft about 1/2 inch. i could feel it moving and it made a creaking sound with every turn of the nut! the wood was groaning a bit too! very interesting experience i must say!
done here! i am excited. there are no more top impellers around i was told by larry in parma at modern parts house. if i break this impeller i'm screwed! if i don't break it the impeller is screwed! off the shaft, literally!
it's off. i took everything in to the sink and washed it all in good soapy water. the pump housing looks great, the impeller is fine, i will however replace the o ring along it's bottom that seals it against the lower drain impeller. the seals look good actually!
the drain impeller is in the background and is the other half of the seal. both look good actually, i wonder if that was where the leak was coming from?
