2. NOTE: This step is for selecting the correct main bearings.
   NOTE: The #1 main bearing is at the front of the engine block.
   • Select the crankshaft main bearings for each crankshaft journal.
   • Record the code that is on the cylinder block face.
   • Record the code that is on the crankshaft flange.
   • The first letter is for main No. 1 and the next letters are for mains 2, 3 and 4.

   Courtesy of FORD MOTOR COMPANY

3. NOTE: This chart is continued in the next step.
   NOTE: This chart is for selecting main bearings 1 and 4 only.
   • Using the data recorded earlier and the Bearing Select Fit Chart, Standard Bearings, determine the required bearing grade for main bearings 1 and 4.
   • 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 2 intersect. This is the required bearing grade(s) for the No. 1 crankshaft main bearing.
   • As an example, if the engine block code letter is "M" and the crankshaft code letter is "M", the correct bearing grade for this main bearing is a "2" for the upper bearing and a "2" for the lower bearing.
   • Repeat the above steps using the fourth letter of the block and crankshaft codes to select the No. 4 bearing.

5. NOTE: This chart is continued in the next step.
   NOTE: This chart is for selecting main bearings 2 and 3 only.
   • Using the data recorded earlier and the Bearing Select Fit Chart, Standard Bearings, determine the required bearing grade for main bearings 2 and 3.
   • Read the second letter of the engine block main bearing code and the second 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 2 intersect. This is the required bearing grade for the No. 2 crankshaft main bearing.
   • As an example, if the engine block code letter is "N" and the crankshaft code letter is "H", the correct bearing grade for this main bearing is "2".
   • Repeat the above steps using the third letter of the block and crankshaft codes to select the No. 3.
