Sounded more like fettling than bodging!

 

To you perhaps. To me it sounded more like a bodge to fit a pump of the wrong dimensions.

Unless the design has been altered, the seal is a carbon ring in a rubber diaphragm pushed onto the back of the impeller by a spring, a bit like the PSS shaft seal. The diaphragm allows the seal to "wave about" yet still stay on the back of the impeller. i don't find it strange, but you were very wise to swap the pump. FWIW unless you have a decent press and a degree of skill to remove the impeller, changing the bearing is not as easy as some here seem to think. You also need to change the seal assembly.

Thanks, Tony.  Always helpful and to the point!
