Install upper main bearings (7). The bearing tabs for the upper main bearings must be located in the correct position in the cylinder block. Lubricate upper main bearings (7) with clean engine oil.
Clean the upper half of the thrust washers and lubricate the upper half of the thrust washers. Place the upper half of the thrust washer on both sides in the recess in the cylinder block of the center main bearing. The grooves on the thrust washer must be located against the crankshaft.
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 the crankshaft in the cylinder block. The weight of the crankshaft is approximately 32 kg (70 lb). Do not scratch any of the finished surfaces on the crankshaft.
Clean the lower half of the thrust washers and lubricate the lower half of thrust washers . Place the lower half of the thrust washers in both sides of the center main bearing cap. The grooves on the thrust washer must be located against the crankshaft.

Install main bearing caps (4) in the position that was marked during the removal process. All of the bearing tabs for the main bearings should be on the same side. Install main bearing cap bolts (3). Tighten main bearing cap bolts (3) to a torque of 245 N m (181 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.
Install connecting rod bearing caps (6). Install new bolts (5) in the connecting rod. Tighten bolts (5) evenly to a torque of 18 N m (13 lb ft). Note: Do Not reuse the old bolts in order to secure the connecting rod cap.Note: Ensure that the etched number on the connecting rod bearing cap matches the etched number on the connecting rod . Ensure that the etched numbers are on the same side.
Tighten bolts (5) evenly to a torque of 70 N m (52 lb ft).
