Ensure that the main bearing journals and the connecting rod bearing journals of the crankshaft are clean. Attach a suitable lifting device in order to position crankshaft (5) in the cylinder block. The weight of the crankshaft is approximately 32 kg (70 lb).Note: Be careful not to damage the finished surfaces on the crankshaft.
Lubricate the lower half of the thrust washers. Place the lower half of the thrust washers on both sides of the rear main bearing cap. The grooves on the thrust washers must be positioned toward the crankshaft.

Apply soapy water to side seals (9). Position side seals (9) in the grooves on the rear main bearing cap with the rounded edges of the seals toward the outside. Use Tooling (C) to push the seal into position in order to reduce the risk of damaging the seal's metal core. Apply Tooling (B) around side seals (9) .
Install the bolts for the rear main bearing cap. Tighten all of the bolts for the main bearing caps to a torque of 98 to 108 N m (72 to 80 lb ft).
Ensure that the upper connecting rod bearings are centered in the connecting rod. Ensure that the lower connecting rod bearings are centered in the connecting rod cap. Lubricate the bearing faces with clean engine oil.Note: Remove the tape or
