Main Moving System: Crankshaft: Reassembly

1. Install a grooved main bearing (upper bearing) on the cylinder block side.
2. Install a groove less main bearing (lower bearing) on the main bearing cap side.
3. Both upper and lower center trust bearings are grovels.

4. Apply engine oil to journals and pins. Install the crankshaft.
5. Install the bearing caps with the arrow mark directed toward the front of the engine. The cap number must be correct.
6. Tighten the cap bolts to the specified torque.

   Tightening torque 

   1. Main bearing cap bolts : 25 N.m (250, 18 lb.ft) + (90°)
7. Cap bolts should be tightened evenly in 4 to 5 increments before they are tightened to the specified torque.
8. Make sure that the crankshaft turns freely and check the end play of the crankshaft.

11. Install the new oil seal case gasket and oil seal case assembly.

    Tightening torque 

    1. Oil seal case : 10-12 N.m (100-120 kg.cm, 7-9 lb.ft)

    < For M/T > 

12. Install the rear plate to the cylinder block.
13. Install the flywheel assembly and tighten the bolts to the specified torque.

    Tightening torque 

    1. Flywheel bolt : 130-140 N.m (1300-1400 kg.cm, 94-101 lb.ft)

    < For A/T > 

14. Install the adapter plate to the cylinder block.
15. Install the drive plate and tighten the bolts to the specified torque.

Tightening torque 

1. Drive plate: 130-140 N.m (1300-1400 kg.cm, 94-101 lb.ft)
