[QUOTE="oexing, post: 142791, member: 1493"] There is another clip of the drive side , link below, well, you cannot go more than to an uninterrupted diameter for checking. At least you get all diameters for checking where ball or roller bearings go. Vincent S. says you better get runout below 1 thou for avoiding bellmouthed outer race seats in engine halves. You can have minimal runout by bashing the webs when from twisted runout. In directions of crankpin and 180 degrees opposite you may tweak it in the vice or wedge it apart depending on what sort of runout - and hope it stays that way when in operation.
