If crankshaft gears (6) were removed, install crankshaft gears (6) on the crankshaft and install bolts (7).
Check the clearance of the bearings. Refer to Disassembly and Assembly, "Bearing Clearance - Check" for the correct procedure.
Illustration 2 g01353563Note: Place clean engine oil on the main bearings and on the connecting rod bearings prior to installation.Note: The upper halves of the main bearings have an oil hole in the center.
Install the upper halves of main bearings (8) in the cylinder block.
Install the upper halves of connecting rod bearings (9) in the connecting rod assemblies.

Typical example
Note: Ensure that the word "FRONT" that is on the end of the crankshaft is toward the front of the engine.
Attach a suitable lifting device to crankshaft (4) and position the crankshaft in the cylinder block. The weight of crankshaft (4) is approximately 762 kg (1680 lb).

Tightening sequence
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.
Place Tooling (C) on the bolts for the main bearing caps.

Place clean engine oil on thrust plates (3). Install thrust plates (3) on each side of the center main bearing.
Place main bearing caps (5) into position and install the bolts. Tighten the bolts in the numerical sequence that is shown above to a torque of 190 14 N m (140 10 lb ft). Tighten the bolts again for an additional 180 5 degrees.
Check the end play with Tooling (B). The end play must not exceed 0.40 0.23 mm (0.0157 0.0091 inch).

Tightening sequence
Place Tooling (C) on the bolts for the connecting rod caps and install the bolts.
Tighten the bolts with the following steps:
Tighten bolts (14) and (15) to a torque of 90 5 N m (65 4 lb ft).
Tighten bolts (16) and (17) to a torque of 90 5 N m (65 4 lb ft).
Tighten bolts (14) and (15) again to a torque of 90 5 N m (65 4 lb ft).
Tighten bolts (16) and (17) again to a torque of 90 5 N m (65 4 lb ft).
Tighten each bolt for an additional 90 5 degrees (1/4 turn). An impact wrench may be used.
Place the remaining connecting rod caps in position and tighten the bolts with the same procedure that is in Steps 12.a through 12.e.
