Cam bearing issue
I have been following this thread with great interest, and have had some issues with camshaft installs myself. Generally only one bearing would give me fits and usually remedied with a small wipe or two with a scotch pad. I am in the process in rebuilding a Kent cross-flow engine and they suggested using fine emery cloth to clean the cam journals. I have never heard of this before, is it done to remove the polished glaze from the journal?
Other web sites also mention it as well, using 600 grit paper and oil on a lathe. Maybe here, and we are only taking cam journals, a dull or hazy surface on the journals would help to retain and carry the oil then a journal that is highly polished....
The pictures the op showed bearings wear on the bottom which pretty much normal as we all know the weight of things are on top. All the bearings look the same, hard to believe anything is bent here. I use assembly grease in these areas, oil doesn't really like to stay put for to long.
