Install dowel (8) in the crankshaft.Protrusion of dowel (8) from the crankshaft face ... 8.4 mm (0.33 inch)
Install dowel (9) in the crankshaft.Protrusion of dowel (9) from the crankshaft ... 4.1 0.5 mm (0.16 0.02 inch)
Install crankshaft gear (7) on the crankshaft with the keyway in alignment with dowel (9). Timing Mark "V" of the gear should face away from crankshaft (6).Note: Install the main bearings dry when clearance checks are performed. Refer to Disassembly and Assembly, "Bearing Clearance - Check". Apply clean engine oil on the main bearings for final assembly.
Install the upper halves of the main bearings in the cylinder block.Note: Ensure that the main bearings are installed so that the bearing tabs fit into the notch in the cylinder block. The upper halves of the main bearings have the oil groove and the oil hole.

Install Tooling (A) and a suitable lifting device on each end of crankshaft (6). The weight of crankshaft (6) is approximately 188 kg (415 lb).
Install crankshaft (6) with Timing Mark "V" on the crankshaft gear in alignment with Timing Mark "V" on the cluster gear.
Install the thrust plates on each side of the No. 4 main bearing.Note: Install the thrust plates with the words "Block Side" toward the cylinder block.
Install the lower halves of the crankshaft main bearings in the main bearing caps.Note: Ensure that the main bearings are installed so that the bearing tabs fit into the notch in the main bearing cap.
Position main bearing caps (4) on the crankshaft.Note: Ensure that the numbers on the main bearing caps match the numbers on the cylinder block. Also ensure that the "FRONT" on the main bearing cap is installed toward the front of the cylinder block.
Lubricate the threads of bolts (3) with clean engine oil. Install bolts (3) and the washers.
Lubricate the threads of bolts (5) and the seal of the washer with clean engine oil. Install bolts (5) and the washers.Note: Inspect the washers that go on bolts (5).
Tighten bolts (3) and bolts (5) for the main bearing caps, as follows:
Tighten Bolt (A) to a torque of 258 14 N m (190 10 lb ft).Note: Bolt (A) is on the bearing tab side of the
