I'm building my engine up right now and i'm looking at my crnak cap jornals and rod journals and they have microscopic cross hatches on them. When you place your finger on the journals, they are smooth, but they can be smoother. Could i lightly sand and polish it up with some fine, fine sandpaper before i put the new bearings on them. I'm a DIYer and i don't want to send it to a shop if i have to.

 

That's great buddy, I'm being serious, could i just smooth them out with fine grade sandpaper?

 

i wouldnt cause you would risk ------- it up, thats something i would leave to the machine shop.

 

perhaps maybe the lines are supposed to be there.

 

600 grit sandpaper. not in one area for to long

 

Don't touch your crank, seriously, Honda made it perfect for you.

 

Now are you talking about the Main caps and Rod caps? or the actual journals on the crank? either or I dont think I'd ---- with them. The only time I ever clean up the journals is if they look like ---- and if in that case you may just want to get the crankshaft micropolished.
