- Record the main bearing code found on the front of the engine block.
- Record the main bearing code found on the back of the crankshaft.
- Using the data recorded earlier and the Bearing Select Fit Chart, Standard Bearings, determine the required bearing grade for each main bearing. Read the first letter of the engine block main bearing code and the first letter of the crankshaft main bearing code. Read down the column below the engine block main bearing code letter, and across the row next to the crankshaft main bearing code letter, until the two intersect. This is the required bearing grade for the number one crankshaft main bearing. As an example, if the engine block code letter is "F" and the crankshaft code letter is "D", the correct bearing grade for this main bearing is a "2". Repeat this process for the remaining four main bearings.
- If oversize bearings are being used, use the procedure in the previous step and the Bearing Select Fit Chart, Oversize Bearings to determine the required bearing grade for each main bearing.
