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.

If this, if that...:blah5:


its all relative....so it's an .001 oversize of a .010 undersize=.009, how exactly does this matter as to helping this duder when its already been stated by me, u and others to have the crank polished or get a .009, .019, or whatever the hell diameter bearing he needs.

I dont care anymore, this dispute is no longer about helping the guy...so im out.
