CRANKSHAFT INSTALLATION


NOTE: Before installing the crankshaft, apply a coat of engine oil to the main bearings and rod bearings.


1. Insert bearing halves in the engine block and connecting rods.
2. Hold the crankshaft so rod journals for cylinder No.2 and No. 3 are straight down.





3. Lower the crankshaft into the block, seating the rod journals into connecting rods No.2 and No.3 and install rod caps and nuts finger tight.
4. Rotate the crankshaft clockwise, seat journals into connecting rods No.1 and No.4, and install the rod caps and nuts finger tight.

NOTE: Reference numbers on connecting rod are for big-end bore tolerance and do NOT indicate the position of piston in engine.

5. Torque the connecting rod nuts to 32 N.m (3.2kg-m, 23 lb-ft.)




6. Install the thrust washers, main bearing halves cap and cap bridge, check clearance with plastigage then torque the nuts to 45 N.m 14.5 kg-m, 33 lb-ft).

7. Install the baffle plate.



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




8. Apply non-hardening liquid gasket to the block mating surface of the right side cover and oil pump case, and install them on the engine block.


NOTE:

- Use HONDA PART NO 08740-99986 for the liquid gasket.
- Check that the mating surfaces are clean and dry before applying liquid gasket.
- Apply liquid gasket by starting with an even bead, centered between edges of the mating surface.
- To prevent leakage of oil, apply liquid gasket to the inner threads of the bolt holes.
- Do not allow the sealant to dry before assembly.
- Wait at least 30 minutes after assembly before filling the engine with oil.




8. Install the oil strainer.
9. Install the oil pan.
