Main Bearing Clearance

Wild you need to step up here

A crank ground UNDERSIZE, as in .010, .020 uses UNDERSIZE bearings.

UNDERSIZE bearings give you LESS clearance, not more.

I did..lol

look everyone..ha ha...if he has too lil clearance he needs either to have the crank polished/ground or a bearing with a larger Inner Diameter=oversized bearings.

undersize technically means the bearing will have a smaller inner diameter.

K? LOL
