How much does it cost to fix a spun bearing?

Why couldn't I just have the rod bearing repaired? It hasn't been driven since the failure occurred.

Firstly - it will likely be difficult to find a repair facility that is willing to invest the time necessary to do this repair - anymore it’s just too cost prohibitive to do major engine work. Next - to complete this repair - the engine MUST be removed - disassembled - the crankshaft will have to be re-machined or replaced - plus connecting rod reconditioning along with replacing all the bearings - and all of that is required just for a “spun bearing” .. Not to mention the other internal engine damage that is sure to be present..... Why would anyone do all of that when it will be less expensive just to replace the engine ? Can’t just pull the oil pan and stick a new bearing in and put it back together - it simply isn’t that easy! .... Plus that wouldn’t last long enough for the engine to start.
