1. Check the connecting rod bearing clearance with Plastigage.
2. Check the main bearing clearance with Plastigage.
3. Install the bearing halves in the engine block and connecting rods.
4. Apply a coat of new engine oil to the main bearings and rod bearings.
5. Hold the crankshaft so rod journal No. 2 and rod journal No. 3 are straight up, and lower the crankshaft into the block.
6. Apply new engine oil to the thrust washer surfaces. Install the thrust washers (A) in the No. 4 journal of the engine block.





7. Inspect the connecting rod bolts.
8. Apply new engine oil to the threads of the connecting rod bolts.
9. Seat the rod journals into connecting rod No. 1 and connecting rod No.
4. Line up the mark (B) on the connecting rod and cap, then install the caps and bolts finger-tight.
10. 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 cap, then install the caps and bolts finger-tight.
11. Tighten the connecting rod bolts to 9.8 Nm (1.0 kgf-m, 7.2 ft. lbs.).
12. 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 7 of the procedure.





13. Remove any old liquid gasket from the bearing cap mating surfaces.
14. Clean and dry the bearing cap mating surfaces.
15. Apply a 1.5 mm wide bead of the liquid gasket, P/N 08717-0004, 08718-0001, 08718-0002, 08718-0003, or 08718-0009, along the broken lines (A).

NOTE: Do not install components if too much time has passed after applying the liquid gasket (for P/N 08718-0002, no more than 4 minutes, for all others, no more than 5 minutes). Instead, remove the old residue and reapply the liquid gasket.





16. Put the bearing cap on the engine block.
17. Apply new engine oil to the threads of the bearing cap bolts.
18. Tighten the bearing cap bolts in sequence to 25 Nm (2.5 kgf-m, 18 ft. lbs.).





19. Tighten the bearing cap bolts an additional 40°.





20. Clean the excess liquid gasket off the engine block.
21. Use the special tools to drive anew crankshaft oil seal squarely into the block to the specified installed height.





22. Measure the distance between the crankshaft (A) and the oil seal (B).





23. Install the dowel pins (A) and a new O-ring (B) on the oil pump (C), then align the inner rotor with the crankshaft, and install the oil pump.





24. Install the oil screen (D) with a new gasket (E).
25. Install the cylinder head.
26. Install the cam chain.
27. Install the IMA motor.
28. Install the engine assembly.

NOTE: When any crankshaft or connecting rod bearing is replaced, after assembly it is necessary to run the engine at idling speed until it reaches normal operating temperature, then continue to run it for about 15 minutes.
