Crankshaft Installation

Special Tools Required

- Driver Handle, 15 x 135L 07749-0010000
- Bearing Driver Attachment, 24 x 26 mm 07746-0010700
- Oil Seal Driver Attachment, 96 mm 07ZAD-PNAA100

1. M/T model: Install the crankshaft pilot bushing when replacing the crankshaft. Using the driver handle, 15 x 135L and the bearing driver attachment, 24 x 26 mm drive in the crankshaft pilot bushing until the driver handle and the bearing driver attachment bottom against the crankshaft.





2. Check the main bearing clearance with plastigage.

3. Check the connecting rod bearing clearance with plastigage.

4. Install the bearing halves in the engine block, the lower block, the connecting rods, and the rod caps.

5. Apply a coat of new engine oil to the main bearings and the rod bearings.

6. Hold the crankshaft so rod journal No. 2 and rod journal No. 3 are straight up, then lower the crankshaft into the engine block. Be careful not to damage the journals.

7. Apply new engine oil to the thrust washer surfaces. Install the thrust washers (A) in the No. 4 journal of the engine block.





8. Inspect the connecting rod bolts Connecting Rod Bolt Inspection.

9. Apply new engine oil to the threads of the connecting rod bolts.

10. Seat the rod journals into connecting rod No. 1 and connecting rod No. 4. Line up the mark (B) on the connecting rod and the cap, then install the caps and bolts finger-tight.

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 bolts finger-tight.

12. Torque the connecting rod bolts to 20 Nm (2.0 kg-m, 14 lb-ft).

13. Tighten the connecting rod bolts an additional 90 °.

NOTE: Remove the connecting rod bolt if you tightened it beyond the specified angle, then 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 lower block mating surfaces, the bolts, and the bolt holes.

15. Clean and dry the lower block mating surfaces.

16. Apply liquid gasket, P/N 08717-0004, 08718-0003, or 08718-0009 to the engine block mating surface of the lower block, and to the inside edge of the threaded bolt holes. 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 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 lower block on the engine block.

18. Apply new engine oil to the threads of the bearing cap bolts. Torque the bearing cap bolts in sequence, to 29 Nm (3.0 kg-m, 22 lb-ft).






19. Tighten the bearing cap bolts an additional 56 °.






20. Torque the 8 mm bolts in sequence to 22 Nm (2.2 kg-m, 16 lb-ft).

NOTE:

- Wait at least 30 minutes before filling the engine with oil.
- Do not run the engine for at least 3 hours after installing the lower block.





21. Apply a light coat of new engine oil to the lip of the crankshaft oil seal.

22. Use the driver handle and the oil seal driver attachment, 96 mm to drive a new crankshaft oil seal (A) squarely into the engine block to the specified installed height.





23. Clean the excess grease off the crankshaft, and check that the oil lip seal is not distorted.

24. Measure the distance between the engine block (A) and the crankshaft oil seal (B).










25. Install the baffle plates.






26. Install the oil pump.

27. Install the oil pan Engine Oil Pan Installation.

28. Install the cylinder head Cylinder Head Installation.

29. M/T model: Install the flywheel, the clutch disc, and the pressure plate.

30. A/T model: Install the drive plate Service and Repair.

31. Install the transmission:

- Manual transmission Manual Transmission Installation
- Automatic transmission Automatic Transmission Installation

32. Install the engine/transmission Engine Installation.

NOTE: Whenever 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.
