Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: Apply clean engine oil to the crankshaft main bearings prior to assembly. Do not apply oil to the back of the crankshaft main bearing. Ensure that the tabs on the back side of the crankshaft main bearings fit in the grooves of the crankshaft main bearing caps and the cylinder block.
Ensure that the crankshaft main bearings are installed in the correct locations. Two different part numbers are used in quantities of three and four. The part number having the quantity of four is to be installed on crankshaft main bearings 2, 3, 5, and 6. The part number having the quantity of three is to be installed on crankshaft bearing 1, 4, and 7. The thrust plate is to be installed on the center crankshaft main bearing only.
Illustration 1 g01147837
Note: The crankshaft end play is controlled by thrust plate (3) . Thrust plate (3) is located at the center of the crankshaft.
Install thrust plate (3) .
Use Tooling (A) to install the new upper halves of crankshaft main bearings (2) in the cylinder block. This half of the bearing has an oil hole.
Illustration 2 g01011713
Install the new lower halves of crankshaft main bearings (2) in crankshaft main bearing caps (1) . Do not apply oil to the back of the crankshaft main bearing.Note: Crankshaft main bearing caps (1) should be installed with the part number toward the right side of the engine. The numerical sequence is identified by stamped numbers 1 through 7 that are located on the bottom surface. The thrust plate is used on the number 4 crankshaft main bearing only.Note: Inspect the bolts for main bearing caps (1) . Refer to Reuse and Salvage Guidelines, SEBF8301, "Inspection and Reuse of Critical Fasteners Used in All Engines" to determine if the bolts should be replaced or reused.
Position crankshaft main bearing caps (1) with the part numbers toward the right-hand side of the cylinder block. Position crankshaft main bearing caps (1) in a numerical sequence.Note: If necessary, use new bolts for the installation of bearing caps (1) .
Apply clean "SAE 30W" oil or molybdenum grease to the bolt threads and the washers. Install the bolts. Refer to Table 2 for torque specifications.
