NOTICE: During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces that enters the oil passages, coolant passages or the oil pan, may cause engine failure.

NOTE: Assembly of the engine requires various inspections/measurements of the engine components (engine block, crankshaft, connecting rods, pistons and piston rings). These inspections/measurements will aid in determining if the engine components will require replacement. For additional information, refer to Section 303-00.

NOTE: If the cylinder head(s) is replaced, a new secondary timing chain tensioner will need to be installed.

   • Read the code on the crankshaft flange.
   • Read the code on the cylinder block face.
     • The first letter after the first asterisk makes up the code for main No. 1 and the next letter for main No. 2. The first letter after the second asterisk makes up the code for main No. 3 and the last letter for main No. 4.

3. NOTE: This chart is for selecting main bearings 1 and 4 only, the remaining bearings will be selected using a different chart in the next step.

   • 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 "F" and the crankshaft code letter is "P", the correct bearing grade for this main bearing is a "1" 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.

4. NOTE: This chart is for selecting main bearings 2 and 3 only.

   • 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 "F" and the crankshaft code letter is "P", the correct bearing grade for this main bearing is "1".
   • Repeat the above steps using the third letter of the block and crankshaft codes to select the No. 3.
