I'm rebuilding this engine because of bad rings, but when I had a closer look at the #2 rod journal I got aware of this mark. It doesnt "catch" my fingernail, but I can feel the surface is not as smooth as the rest of the journal. The rod bearing looks like the rest of the bearings, only normal wear. Can I just reuse the crank or do I have to get it to a shop for resurface?

Thanks

 

i would have the crank journals lightly micro-polished. then have the correct bearings measured and selected.

 

OK, thanks. I'll try that and slap it together. Hope it'll work

 

i wouldnt worry about them.. its sometimes normal.. how do the bearings look? if anything thats from initial start-up.. i wouldnt waste the money..
