(1) with a gage pad inner diameter were measured * should pad installed and tightened to a predetermined torque), and the outer diameter of the journal, the difference between the two diameters is bearing gap.contact ball bearing

(2) with a width of about 10 mm, a length slightly less than the pad width, of a thickness equivalent to allow the repair of a gap brass, cis axially placed in between the bearing and the journal, with a predetermined torque after tightening, in the reduced pressure state under test turn crankshaft (be careful not to use excessive force, so as not to damage the bearing), such as rotation, show that the gap is too large.engine bearings

(3) between the bearing and journal, is perpendicular to the axial direction, put an appropriate thickness of a soft metal sheet or the soft wire, to tight vagay predetermined torque after, remove the soft metal sheet, its thickness is measured, this value is the bearing clearance.angular contact bearing
