Gang, Neighbor has a Wayne Model SWS50 1/2HP jet pump which quit pumping. It is used for cistern water. She has city water also, so no panic, but I wanted to help out. Checked the pump and motor is running fine but the inside of the pump is "growling" quite a bit and I am assuming the impeller, etc., is shot. Pulled the pump and now have it in my garage. Picture and parts list can be seen at:

problem is: I have removed the 4 bolts which "should" hold the motor and impeller stuff inside the casting for the pump, but I cannot get the motor and impeller to come out of the housing of the pump. I admit, it's pretty gunked up in there and maybe the crud is just keeping it from being removed, but I've been wiggling, prying, etc., and don't seem to be making any progress. Haven't tried tapping/beating/smashing anything as of yet and hope I don't have to. There is no access to any internal parts through the water inlet or outlets or anywhere else, just the four bolts that hold it together. Anyone with experience that could help, suggest??? The four bolts are item #2 on the drawing and item #3 is called a seal plate. It may be the seal plate which is "frozen" into place but the motor won't pull back far enough to allow me to do much of anything in the end of the housing. The nozzle (#11) in the print may stick into the housing far enough that a rod inserted through a 1/4" pipe plug hole at #14 may allow me to tap it back out of the housing, but I probably would ruin the nozzle in the process. Ideas would be appreciated.... Ken.
