How do I pull the piston out of my motomaster twin stack - 5 gallon compressor?


The model # 058-7949-6 has a 2 hp motor.
If I plug it in, it only hums. So I pulled the head off and examined the piston, cylinder wall and rings - they look OK. I can turn the impeller by hand but only about a half turn. Then the piston binds the engine body - no flex/mobility. I'm wondering if the bearing is welded/bonded to the shaft? How do I get the bearing out??? THANKS for any INFO/videos you can provide.
