Circulator pump frozen on propeller side what causes this

kingjames

I Have another zone not used with same pump can I swap the bearing shafts or is there any trouble shooting I can do to try and free it have oiled pumps

A frozen bearing is almost always due to a lubrication problem. That's the good news. The bad news is that once a bearing of this type has frozen, both the bearing and the associated shaft are damaged and no attempt should be made to use them again.

Put a 007e on there and be done with it. Look at the rusted, leaking flange.

Could also be a jammed impeller from rust and scale build-up?

If you want to swap from one to the other? I would swap the entire bearing assembly or the entire circulator. Can't see how much work one or the other will be from here. Your call.

Or the water from the leak flooded the bearing and wick cavity. Sometimes they can  be salvaged if the seal is still holding. 

Better start shopping for the replacement assembly

if it is a zone valve system, an ECM will save energy and smooth out pumping-operation.

I was hoping that it was a rust and scale build up and once I took it out it would clear propeller just don’t have the money right now to hire someone and all the nuts are rusty or I would replace it with other one so I figured I might be able to swap shaft and bearing

Put some penetrating oil on the protruding threads and use some sockets or wrenches, if they fit properly they will either unscrew the bolts or shear them off so you can replace them.

I've replaced quite a few 3 piece circulators with modern wet rotor circulators. The rusty hardware can be overcome with a Sawzall or preferably an angle grinder. Then it's pretty straightforward to change it out. Usually the cause of failure is lack of proper maintenance.

That pic is a sign of neglect. You can pull off the cover that the oil port is connected to and look at the wicking and the impeller shaft. Might pull the wicking out and put some Mystery Oil from the autoparts store on it and try and work it in. But... be aware that there is a shaft seal with a ceramic bearing to keep the water out of that compartment. What shape is that in???

Without the money, you will need to just go without heat in that zone. Perhaps you can drain the water from those pipes so they don't freeze and cause a pipe to split.

I have heard it said, "If you can't afford to do it right, how do you expect pay to do it again?" You should do the necessary maintenance on the rest of the system before you have another failure.

As far as swapping the bearing assembly from another pump. After you drain the water from the pipes, and purchasing a gasket, you can swap a working bearing assembly for the seised bearing assembly.
Don't try it without the gasket. They never stay in one piece like the flange gaskets do (sometimes)

Note that most of what i learned to do i learned because i grew up not being able to pay someone to do it.
