5) Install the crankshaft upper bearing to the cylinder block.

Note

  • Check that the crankshaft upper bearing has oil holes and an oil groove.

Caution

  • Do not confuse the difference of bearing shapes.

6) Apply engine oil to the sliding surface of the crankshaft upper bearing.

Caution

  • Do not apply engine oil to the cylinder block installation surface and back surface of the bearing.

7) Thoroughly apply engine oil to the crankshaft journal section.

8) Install the crankshaft to the cylinder block.

Caution

  • Prevent the crank angle sensor rotor from coming in contact with the cylinder block, etc., when installing the crankshaft.

9) Thoroughly apply engine oil to the thrust bearing.

10) Install the thrust bearings to the front and rear sides of the cylinder block No. 3 journal.

Caution

  • Install so that the oil groove of the thrust bearing touches the crankshaft.

11) Install the lower crankshaft bearing to the bearing cap.

12) Apply engine oil to the sliding surface of the lower crankshaft bearing.

Caution

  • Do not apply engine oil to the bearing cap installation surface and back surface of the bearing.

13) Install the bearing caps to the cylinder block in the order shown in the diagram.

Note

  • Install so that the bearing cap front mark faces the front of the engine.

14) Apply engine oil to the threaded portions and seating surfaces of the bolts.

15) Final tighten the bearing cap bolts gradually to the cylinder block in the order shown in the diagram.

Tightening torque: 167 N・m { 17.0 kgf・m / 123 lb・ft }

16) Check that the crankshaft turns smoothly by rotating it manually after tightening each bearing cap location.

3. CKP sensor installation

1) Install the CKP sensor to the cylinder block.

Tightening torque: 5.0 N・m { 0.5 kgf・m / 44 lb・in }
