Crankshaft Installation

Crankshaft Installation

Special Tools Required
^ Handle driver 07749-0010000
^ Oil seal driver attachment 07ZAD-PNAA100

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 engine block.
6. 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 and flange of the connecting rod bolts.
9. Seating 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 lbf-ft).
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. Do not loosen it back to the specified angle.





13. Remove old liquid gasket from the bearing cap bridge mating surfaces.
14. Clean and dry the bearing cap bridge mating surfaces.
15. Apply a 1.5 mm wide bead of the liquid gasket, P/N 08717-0004, 08718-0001, 08718-0003, or 08718-0009, along the broken lines (A). Install the component within 5 minutes of applying the liquid gasket.

NOTE:
^ 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.





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





19. Tighten the bearing cap bolts an additional 40°.
20. Clean the excess liquid gasket off the engine block.
21. Use the handle driver and oil seal driver attachment to drive a new oil seal squarely into the engine block to the specified installed height.





22. Measure the distance between the crankshaft and oil seal.





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





24. Install the oil screen (D) with new gasket (E).
25. Install the cylinder head.
26. Install the cam chain.
27. M/T model: install the flywheel, clutch disc, and pressure plate.
28. A/T model: Install the drive plate.
29. Install the transmission:

^ Manual transmission.
^ Automatic transmission.

30. Install the engine assembly.

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