Use the lifting device to align flywheel housing (3) with Tooling (A). Install the flywheel housing to the cylinder block.
Install bolts (1) and bolts (2) to the flywheel housing.
Remove Tooling (A). Install remaining bolts (2).
Follow Step 11.a through Step 11.b to tighten bolts (1) and bolts (2) in the tightening sequence that is shown in Illustration 5.
Tighten bolts (1) to a torque of 78 N m (58 lb ft).
Tighten bolts (2) to a torque of 63 N m (46 lb ft).
Check the alignment of flywheel housing (3) with the crankshaft. Refer to System Operation, Testing and Adjusting, "Flywheel Housing - Inspect" for more information.End By:
