    NOTICE

    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.


  1. Place crankshaft main bearing caps (2) in position on the cylinder block. Apply clean engine oil or Molylube on the bolt threads and on the washer face. Install bolts (1) .

  1. Tighten bolts (1) to a torque of 54 ± 7 N·m (40 ± 5 lb ft). Tighten each bolt (1) for an additional 90 ± 5 degrees (1/4 turn).

  1. Check the end play of the crankshaft with Tooling (B). The end play must be 0.07 to 0.32 mm (0.003 to 0.013 inch).

End By: Install the engine oil pump. Refer to Disassembly and Assembly, "Engine Oil Pump - Install".
