Raise the temperature of crankshaft gear (3). Install crankshaft gear (3) on the crankshaft with the keyway in alignment with the dowel. Timing Mark "V" is toward the outside of the crankshaft. The notch in the gear must be in alignment with the dowel in the crankshaft. Note: Install the main bearings dry when clearance checks are made. Apply clean engine oil on the main bearing for final assembly.

Install Tooling (B) and a suitable lifting device on crankshaft (8). The weight of crankshaft (8) is approximately 215 kg (475 lb). Install crankshaft (8).
Illustration 5 g01096760
Ensure that Timing Marks “V” are aligned on idler gear (4) and crankshaft gear (3).
Illustration 6 g00567844Note: Install the thrust plates with the identification "Block Side" toward the cylinder block.
Apply clean engine oil to thrust plates (7). Install thrust plates (7) next to the center main bearings.
Illustration 7 g01096761
Install the lower half of the main bearings in main bearing caps (6).
Check the bearing clearances with Tooling (E). Note: Ensure that the numbers on main bearing caps (6) match the numbers on the cylinder block. The arrows on main bearing caps (6) are toward the front of the cylinder block.
Install main bearing caps (6). Apply Tooling (G) to bolts (5). Install bolts (5) in main bearing caps (6). Tighten the bolt on the tab end of main bearing caps (6). Next, tighten the other main bearing cap bolt. Tighten all bolts to a torque of 258 14 N m (190 10 lb ft).
Illustration 8 g01097026
Put a mark on each bolt and each main bearing cap (6). Tighten the bolt on the opposite side of the tab end of main bearing cap (6) for an additional Dimension (X). Dimension (X) is 120 5 degrees. Next, tighten the bolt on the tab end of main bearing cap (6) for an additional Dimension (X). Dimension (X) is 120 5 degrees.
Illustration 9 g01096759
Install the lower half of the connecting rod bearings in connecting rod caps (1). Apply Tooling (G) to the connecting rod bolt threads. Install connecting rod caps (1) on the connecting rods. The
