[QUOTE="INEEDA_TERMI, post: 13565943, member: 127344"] 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, can cause engine failure. NOTICE: During engine assembly do not allow the piston connecting rods to come in contact with the piston cooling jets or engine damage may occur. NOTE: During engine assembly it may become necessary to check bearing clearances and end play. For additional information, refer to Section 303-00. NOTE: The Boss® 302 requires Motorcraft® SAE 5W-50 Full Synthetic Motor Oil, all other 5.0L (4V) engines require Motorcraft® SAE 5W-20 Premium Synthetic Blend Motor Oil. Record the main bearing code found on the front of the engine block. Record the main bearing code found on the rear of the crankshaft. NOTE: This chart is for selecting main bearings 1 and 5 only, the remaining bearings will be selected using a different chart in the next step. [ATTACH=full]514145[/ATTACH] Using the data recorded earlier and the Bearing Select Fit Chart, Standard Bearings, determine the required bearing grade for main bearings 1 and 5. 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 fifth letter of the block and crankshaft codes to select the No. 5 bearing. NOTE: This chart is for selecting main bearings 2, 3 and 4 only. [ATTACH=full]514146[/ATTACH] Using the data recorded earlier and the Bearing Select Fit Chart, Standard Bearings, determine the required bearing grade for main bearings 2, 3 and 4. 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(s) 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 a "1" for the upper bearing and a "2" for the lower bearing. Repeat the above steps using the third and fourth letters of the block and crankshaft codes to select the No. 3 and No. 4 bearings. [/QUOTE]
