This is definitely way over DIY level this forum represents.
How did you judge bad bearing?
Seeing how complex those engines are, I doubt you can do much without pulling engine out and then it is only logical choice to give it complete overhaul.

Have you ever changed bearings on crankshaft
I have changed Crankshaft bearings and cam bearings and pistons with the engine in the vehicle. But not on a 211, of course you have be able to remove the oil pan, but the main trick is to only remove one bearing cap at a time AND you can roll out the upper bearing using a soaked in water popsicle stick as a pusher tool to remove the old bearing. Do not use anything metal to attempt to remove the bearing. Pay attention to the orientation of the oil holes on the OLD bearing so you get the new bearing installed with out covering the galleries, because you wont be able to see them, and this is where you could really screw up! You may need to roll the crankshaft while pushing.
