The main bearings are a "select fit" to achieve proper oil clearances. For main bearing selection, the block and crankshaft have grade identification
marks.
The marks for the cylinder block main bore grade are located on the left side pan rail, just rear of the left engine mount bracket. These grade marks (1,
2, or 3) are read left to right, corresponding to main bore 1, 2, 3, 4.

Figure 17 Crankshaft Main Journal Grade Marking Location - Rear Of Block (Inverted) View
The grade marks for the crankshaft are located on the rear-most crankshaft counter weight. The crankshaft journal grade marks (A, B. or C) are read
left to right, corresponding with journal number 1, 2, 3, 4.
Use the Main Bearing Selection Chart to properly select the main bearings. For an example, if the main bore grade is 3 and the journal grade is B. the
proper select fit bearing would be a (2) +0.003 mm (+0.0002 inch).
