Main Bearing Clearance
Yeah but them are undersize. What I was sayin.....and you know it dammit....was that when you get a crank turned, the crankpin diameter decreases. So, as such, you need a bearing with a decreased or undersized inside diameter. Unless you're simply trying to get dead specific on clearances, you'll generally not need an "oversize" bearing. In other words, if the machinist does his job, the undersize bearings will be right.
