If crankshaft gear (1) was removed, install the gear on crankshaft (2).
Check the clearance of the main bearings. For the correct procedure, see this Disassembly and Assembly, "Bearing Clearance - Check" topic.
Illustration 2 g00577547Note: The upper halves of the main bearings have an oil hole in the center.
Install the upper halves of main bearings (3) in the cylinder block. Coat the bearings with clean engine oil.
Install the upper halves of connecting rod bearings (4) in the connecting rod assemblies. Coat the bearings with clean engine oil.

Typical example
Note: Ensure that the word "FRONT" that is on the end of the crankshaft is toward the front of the engine.Note: The weight of the crankshaft is approximately 590 kg (1300 lb).
Attach a suitable lifting device to crankshaft (2) and position the crankshaft in the cylinder block.
Ensure that the lower halves of the main bearings are in position in the main bearing caps. Coat the bearings with clean engine oil. Note: The main bearing caps must be installed with the word "FRONT" and the part number toward the front of the engine. Each main bearing cap has a number on the bottom surface and each main bearing must be installed in the corresponding position in the cylinder block.

Bolt tightening sequence for main bearing caps
(X) Front of engine
Coat the threads of the bolts for the main bearing caps with clean SAE 30 engine oil. Except for the center main bearing cap, place the main bearing caps into position. Install the bolts and washers. Tighten the bolts according to the sequence that is shown in Illustration 4. Tighten the bolts to a torque of 190 14 N m (140 10 lb ft). Then tighten the bolts for an additional 180 5 degrees (1/2 turn).

Place clean engine oil on thrust plates (9). Install thrust plates (9).
Install the center main bearing. Use the tightening procedure that is in Step 7.
Use Tool (B) to measure the end play of the crankshaft. The end play must not exceed 0.17 to 0.63 mm (0.007 to 0.025 inch).
Make sure that the upper halves of the bearings are in position on the connecting rods. Make sure that the lower halves of the bearings are in position on the connecting rod caps.
Check the clearance of the connecting rod bearings. For the correct procedure, see Disassembly and Assembly, "Bearing Clearance - Check".
Position one connecting rod onto a journal of the crankshaft. Note: The number that is on the side of the connecting rod caps must be installed next to the corresponding number that is on the side of the connecting rod.
