11. Rotate the crankshaft clockwise, and seat the journals into connecting rod No. 2 and connecting rod No. 3. Line up the mark on the connecting rod and the cap, then install the caps and the bolts finger-tight.
12. Torque the connecting rod bolts to 9.8 N-m (1.0 kgf-m, 7.2 lbf-ft).
13. Tighten the connecting rod bolts an additional 90 °.
NOTE: Remove the connecting rod bolt if you tightened it beyond the specified angle, and go back to step 8 of the procedure. Do not loosen it back to the specified angle.
14. Remove all of the old liquid gasket from the bearing cap bridge mating surfaces the bolts, and the bolt holes.
15. Clean and dry the bearing cap bridge mating surfaces.
16. Apply liquid gasket (P/N 08717-0004, 08718-0003, or 08718-0009) to the engine block mating surface of the bearing cap bridge. Install the component within 5 minutes of applying the liquid gasket.
NOTE:
- Apply a 2.5 mm (0.098 in) diameter bead of liquid gasket along the broken line (A).
- If you apply liquid gasket P/N 08718-0012, the component must be installed within 4 minutes.
- If too much time has passed after applying the liquid gasket, remove the old liquid gasket and residue, then reapply new liquid gasket.
17. Put the bearing cap bridge on the engine block.
18. Apply new engine oil to the threads of the bearing cap bolts.
19. Torque the bearing cap bolts in sequence to 25 N-m (2.5 kgf-m, 18 lbf-ft).
20. Tighten the bearing cap bolts an additional 40 °.
21. Clean the excess liquid gasket off the engine block.
22. Clean and dry the crankshaft oil seal housing.
23. Apply a light coat of new engine oil to the lip of the crankshaft oil seal.
24. Use the driver handle, 15 x 135L, and the oil seal driver attachment, 96 mm, to drive a new crankshaft oil seal squarely into the block to the specified installed height.
25. Measure the distance between the cylinder block (A) and the oil seal (B).
26. Install the cylinder head Cylinder Head Installation.
27. Install the oil pump (A) with a new O-ring (B).
28. Install the oil screen (C) with a new gasket (D).
29. Install the oil pan Engine Oil Pan Installation.
30. Install the cam chain Cam Chain Installation.
31. Connect the CKP sensor connector (A), then install the CKP sensor cover (B).
32. Install the harness cover (C).
33. Install the IMA motor rotor position sensor Service and Repair, the IMA motor housing IMA Motor Housing Removal/Installation, and the IMA motor rotor Service and Repair.
34. Install the transmission CVT Transmission Installation.
35. Install the engine/IMA motor/transmission assembly Engine Installation.
NOTE: When any crankshaft or connecting rod bearing is replaced, run the engine at idle until it reaches normal operating temperature, then continue to run it for about 15 minutes.
