Crankshaft Installation

Installation

Special Tools Required
^ Handle Driver 07749-0010000
^ Driver Attachment, 96 mm 07948-SB00101 or 07VAD-P8A010A

1. Check the connecting rod bearing clearance with plastigage.
2. Check the main bearing clearance with plastigage.
3. Apply engine oil to the main bearings and rod bearings.
4. Install the bearing halves in the cylinder block and connecting rods.
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. Install the thrust washers (A) on both edges of the No. 4 main bearing recess.
7. Apply engine oil to the threads of the connecting rod bolts.
8. Seat the rod journals into connecting rod No. 1 and connecting rod No. 4. Install the caps and nuts finger tight. Install the cap so the bearing recess is on the same side as the recess in the rod.
9. Rotate the crankshaft clockwise, and seat the journals into connecting rod No.2 and connecting rod No. 3. Install the connecting rod cap and bolts finger tight.
10. Tighten the connecting rod bolts to 32 Nm (3.3 kgf-m, 24 ft. lbs. ).
11. Install the bearing cap bridge. Coat the bolt threads with engine oil.
12. Torque the bearing cap bolts sequentially in two steps.
1st step torque: 25 Nm (2.5 kgf-cm, 18 ft. lbs.)
2nd step torque: 51 Nm (5.2 kgf-cm, 38 ft. lbs.)

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





Bearing Cap Bolts Tightening Sequence:

13. The seal mating surface on the engine block end cover should be dry. Apply a light coat of grease to the crankshaft and to the lip of the seal.





14. Drive the crankshaft oil seal squarely into the engine block end cover.





15. Confirm that the clearance is equal all the way around with a feeler gauge.
Clearance: 0.5 - 0.8 mm (0.02 - 0.03 inch)
16. Clean and dry the engine block end cover mating surfaces.





17. Apply liquid gasket, P/N 08718-0001 or 08718-0003, evenly to the block mating surface of the engine block end cover and to the inner threads of the bolt holes. Install the dowel pins (A), and the engine block end cover (B) on the cylinder block.

NOTE: Do not install the parts if 5 minutes or more have elapsed since applying the liquid gasket. Instead, reapply liquid gasket after removing the old residue.

18. After assembly, wait at least 30 minutes before filling the engine with oil.
19. Clean and dry the oil pump mating surfaces.





20. Install the oil pump (A).
-1 Install a new crankshaft oil seal in the oil pump.
-2 Apply liquid gasket, part No. 08718-0001 or 08718-0003, evenly to the block mating surface of the oil pump and to the inner threads of the bolt holes.
-3 Grease the lip of the oil seal and apply oil to the new O-ring (B).
-4 Install the dowel pins (C), then align the inner rotor with the crankshaft and install the oil pump.
-5 Clean the excess grease off the crankshaft and check the seal for distortion.
21. Install the oil screen (D) with a new gasket (E).
22. Install the oil pan:
^ Aluminum Oil Pan Type.
^ Steel Oil Pan Type.
