    Can anyone ID this 350 main bearing? Thought I would see a .010" or something indicating size.

    Just pulled one cap off, motor is still together and at the shop not in my garage. Heading to the machine shop this week but trying to get an idea if I'll be looking for a crank due to some scoring.

    I would bet that if it doesn’t say 10 or 20 then it’s standard size but the mic will tell.

    I just calipered a std main bearing thickness at .094
    So I would think .010 mains would measure .094 + .005 per half = .099 and so on for .020 or .030 mains.

    Thanks Mart. Getting .098 on a worn bearing so .010 bearing is likely. Hope not, but likely.
