Big Problem, Hopefully Simple Solution

[RUSURE]

So, we lifted the talon up on a host, took everything off necessary to get the oil pan off to look at the crank. Everything was fine until we found out that number 3 bearing was moving a little. So we took a pry bar to see if the crank was able to shift as well, stiff as a board, which is a good thing. All other bearings were fine, really tight and couldn't move what so ever except number 3. So, I said, why don't we just put another bearing in right? Or will this cause the same thing to happen again. My buddy that was helping me is a mechanic, well, pretty much, he does all this kinda stuff but he said that he doesn't think you can just put a new bearing in??

Inside the bearing there is a little lip on one side, I believe this was "melted" right down and is was not smoot anymore, kinda felt like when you brake pads go right to the melt and grind your discs.

Question, can I or can't I just put a new rod bearing in?

Take the rod off the crank and inspect the face of the crank and behind the bearing on the rod. pretty much if you see and groves and can feel them with your finger nail then you need to get the crank redone. if the crank and everything looks good and there are no gouges and such then you can slap a new bearing in there plastigage the clerance and if it all checks out, lots of lube and you should be good to go.

Also if there are any metal shaving in the oil pan/oil then you need to clean out your block to prevent metal shavings from damaging other bearing and such after work is completed.

Good luck, and hopefully everything works out fine

Well, we found very very small and barely any metal shavings, I think I got lucky and caught the problem before it got too big, but, we took the capping off the bearing(like two separate pieces of metal, U shaped) and underneath that it was rough, like we could feel groves.

Ok, where were the rough groves at? On the crank face or on the rod face? also you are going to need to clean all the metal shavings from the block and head.

they are on the rod face, my buddy says it's too bad for machining.
