Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Clean the crankshaft and inspect the crankshaft for wear and damage. Refer to Specifications, "Crankshaft" for more information. If necessary, replace the crankshaft or recondition the crankshaft.
If necessary, install the crankshaft gear. Refer to Disassembly and Assembly, "Crankshaft Gear - Remove and Install" for the correct procedure.
Ensure that parent bores for bearing shells in the cylinder block are clean. Ensure that the threads for the main bearing bolts in the cylinder block are clean and free from damage.
Clean the main bearing shells and the thrust washers. Inspect the main bearing shells and the thrust washers for wear and damage. If necessary, replace the main bearing shells and the thrust washers.Note: If the main bearing shells are replaced, check whether oversize main bearing shells were previously installed. If the thrust washers are replaced, check whether oversize thrust washers were previously installed.

Lubricate thrust washers (6) with clean engine oil. Install thrust washers (6) into number six main bearing in the cylinder block.Note: The grooves in the thrust washers must be located against the crankshaft. The thrust washers have a locating tab at one end. Ensure that the locating tabs are correctly seated in the cylinder block.

Install lower main bearing shells (5) into main bearing caps (4). Ensure that the locating tabs for lower main bearing shells (5) are correctly seated into the slots in the bearing caps.Note: The lower main bearing shells are plain bearings that do not have oil holes.
Lubricate lower main bearing shells (5) and lubricate the journals of the crankshaft with clean engine oil. Install main bearing caps (4) to the cylinder block.Note: Ensure the correct location and orientation of main bearing caps (4). The locating tabs for the upper and the lower main bearing shells should be on the same side of the engine.
Illustration 5 g06324887
Lubricate the threads of bolts (3) with clean engine oil. Lubricate the underside of the heads of bolts (3) with clean engine oil.
Install bolts (3) to main bearing caps (4). Evenly tighten the bolts to pull the caps into position. Ensure that the caps are correctly seated.Note: Do not tap the main bearing caps into position as the bearing shells may be dislodged.
Tighten bolts (3) to a torque of 80 N m (59 lb ft). Turn bolts (3) through an additional 90 degrees. Use Tooling (B) to achieve the final torque.
Rotate the crankshaft to ensure that there is no binding.
