Depending on the presented defect on the bearing
shells it is possible to identify what is the problem of
the engine: excessive clearance, out-of-roundness or
taper. A failure or excessive clearance also can be
detected by the reduction of the lubricant oil pressure.
The prolonged operation with low oil pressure can cause
beats and vibrations in crankshaft and consequently
early deterioration of the bearing shells.
To perform the measurement of the bearings with the
bearing shells installed, well clean the bearing cap,
avoiding distortion due to oil or dirt presence.
Also clean bearing bolt holes. The holes must be
completely free of oil residues, splinters and
impurities.
