3. Crankshaft pulley bolt/screws (246) and pulley (194), if equipped with mechanical fan.
4. Balancer bolts/screws (46) and balancer assembly (42).
5. Match mark crankshaft hub (45) to engine front cover assembly.
- Do not crank engine over after match marking crankshaft hub and engine front cover assembly. Rotating crankshaft assembly will misalign installation of crankshaft hub and balancer assembly to crankshaft assembly possibly resulting in engine imbalance.
6. Crankshaft hub bolt/screw (43) and washer (44).
