Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: Place clean engine oil on the crankshaft main bearings prior to assembly. 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 g01022781
Install thrust plate (4) on the crankshaft.
Use Tooling (A) and install the new upper halves of crankshaft main bearings (3) in the cylinder block. This half of the bearing has an oil hole. Do not put oil on the back of the crankshaft main bearing.
Illustration 2 g01022767
Install the new lower halves of the crankshaft main bearings in crankshaft main bearing caps (2) . Do not put oil on the back of the crankshaft main bearing.
Crankshaft main bearing caps should be installed with the part number toward the right side of the engine. Crankshaft main bearing caps are to be identified by stamped numbers 1 through 7 located on the bottom surface. The thrust plate is to be installed in the original position on the crankshaft main bearing.
Place crankshaft main bearing caps (2) in position on the cylinder block. Place clean engine oil or Tooling (C) on the bolt threads and the washer face. Install bolts (1) .
Tighten the bolts to a torque of 95 5 N m (70 4 lb ft). Place an index mark on each bolt head. Tighten each bolt for an additional 90 5 degrees (1/4 turn).
Check the end play of the crankshaft with Tooling (B) . The end play must be 0.10 mm (0.004 inch) to 0.50 mm (0.020 inch).Note: The crankshaft end play is controlled by crankshaft thrust bearings (4) . Thrust bearings (4) are located at the center of the crankshaft.End By: Install the oil pan. Refer to Disassembly and Assembly, "Engine Oil Pan - Remove and Install".
