Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Ensure that the crankshaft main bearing tabs engage with the grooves in the block and the crankshaft main bearing cap.
Note: The number six main bearing is the thrust bearing.
Clean the bearing surfaces in the cylinder block for the main bearings. Apply clean engine oil to the upper main bearing. Do not apply engine oil to the back side of the bearing surfaces. Install the upper main bearings in the cylinder block. Ensure that the tab on the back side of the bearing engages with the groove in the cylinder block.

Apply clean engine oil to the journals of the crankshaft bearing. Attach a suitable lifting device to crankshaft (1). The weight of crankshaft (1) is approximately 62 kg (137 lb). Align the identification marks on the gear train. Install crankshaft (1) in the cylinder block.
Clean the bearing surface of main bearing caps (3). Install the lower main bearings in the main bearing caps. Ensure that the tab on the back side of the bearing engages with the groove in the main bearing cap. Apply clean engine oil to the lower main bearings. Do not apply engine oil to the back side of the bearing surfaces.
Install main bearing caps (3) with the part numbers toward the right hand side of the cylinder block. Ensure that the main bearing caps have numbers 1 through 7. The numbers should start at the front of the engine. Apply clean engine oil or Molylube to the bolt threads and the washers.Note: When the bolts for the rear main bearing cap are tightened, slide the main bearing cap as far forward as possible until the cap is against the bolts. Hold the main bearing cap in this position and tighten the bolts.
Install bolts (2) for main bearing caps (3). Tighten bolts (2) to a torque of 54 7 N m (40 5 lb ft).
Turn bolts (2) for an additional 90 5 degrees (1/4 turn).
Check the end play of crankshaft (1) with Tooling (A). The end play must be 0.07 mm to 0.32 mm (0.003 inch to 0.013 inch).End By:
Install the flywheel housing. Refer to Disassembly and Assembly, "Flywheel Housing - Remove and Install".
Install the front housing. Refer to Disassembly and Assembly, "Housing (Front) - Install".
