Main Bearing Identification
Upper and lower Number 3 bearing halves are flanged to carry the crankshaft thrust loads and are NOT interchangeable with any other bearing halves in
the engine. All bearing cap bolts removed during service procedures are to be cleaned and oiled before installation. Bearing shells are available in
standard and the following undersized: 0.025 mm (0.001 in.), 0.051 mm (0.002 in.), 0.076 mm (0.003 in.), 0.254 mm (0.010 in.), and 0.305 mm (0.012
