    a haynes book can tell you. im at work or i would look in my book for ya, cause i cant remember. oil clearance for the bearings has something to do with i believe some kind of mylar strip(?) laid long ways on the crank journal and put main caps on,torque, and remove to measure how wide the strip was flattened out and the book gives you allowable tolerences
