Installation

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


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

Seating Crankshaft Into Block:

3. Lower the crankshaft into the block, seating the rod journals into connecting rods No.2 and No.3. Install the 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: Install caps so the bearing recess is on the same side as the recess in the rod.


5. Check rod bearing clearance with plastigage, then torque the cap nuts:
47 Nm (4.7 kg-m, 34 lb ft)

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

Torque Sequence:

6. Install the thrust washers, main bearing caps and bearing cap bridge.
- Check clearance with plastigage, then tighten the bearing cap bolts in 2 steps.
- In the first step tighten all bolts in sequence to about 30 Nm (3.0 kg-m, 22 lb ft).
- In the final step tighten in same sequence to 75 Nm (7.5 kg-m, 54 lb ft).

NOTE: Coat thrust washer surfaces and bolt threads with oil.

CAUTION: 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 approximately 15 minutes.







7. Insert the balancer shafts into the block, then install the retainer to the front balancer shaft and block.

Right Side Cover:

Cover Installation:

8. Apply liquid gasket to the block mating surface of the right side cover. Apply a light coat of oil to the crankshaft and to the lip of the seal, then install the cover on the engine block. Torque the 6 x 1.0 mm bolts to 12 Nm (1.2 kg-m, 9 lb ft).


NOTE:
- Use liquid gasket, part No. 08718-0001.
- Check that the mating surfaces are clean and dry before applying liquid gasket.
- Apply liquid gasket evenly, being careful to cover all the mating surface.
- To prevent leakage of oil, apply liquid gasket to the inner threads of the bolt holes.
- Do not install the parts if 20 minutes or more have elapsed since applying the liquid gasket. Instead reapply liquid gasket after removing the the old residue.
- After assembly, wait at least 30 minutes before filling the engine with oil.

Oil Pump:

9. Apply liquid gasket to the block mating surface of the oil pump, then install it on the engine block. Torque the 6 x 1.0 mm bolts to 12 Nm (1.2 kg-m, 9 lb ft).

- Apply grease to the lips of the oil pump seal and the balancer seal.
Then, install the oil pump inner rotor onto the crankshaft. When the pump is in place, clean any excess grease off the crankshaft and the balancer shaft, then check that the oil seal lips are not distorted.

Oil Pump And Screen Installation:

10. Install the baffle plate, then install the oil screen. Torque the 6 x 1.0 mm bolts to 12 Nm (1.2 kg-m, 9 lb ft).

Balance Shaft Gear Drive Installation:

11. Apply molybdenum disulfide to the thrust surfaces of the balancer gears as shown, before installing the balancer driven gear and the balancer drive gear case.

Rear Balancer Shaft Driven Gear:

12. Hold the rear balancer shaft with a 6 x 100 mm bolt, then install the balancer driven gear.

Balancer Driven Pulley Removal:

13. Hold the front balancer shaft with a screwdriver, then install the timing balancer belt driven pulley. Torque the 8 x 1.25 mm bolt to 30 Nm (3.0 kg-m, 22 lb ft).

Installing Balancer Gear Case:

14. Install the balancer gear case to the oil pump. Torque the 8 x 1.25 mm bolt to 25 Nm (2.5 kg-m, 18 lb ft).

NOTE: Align the groove on the pulley edge with the pointer on the gear case while holding the rear balancer with 6 x 100 mm bolt, then install the gear case.

Check Alignment Of Pointers Both Shafts:

15. Check alignment of pointers after installing the gear case.

Oil Pan Installation:

16. Install the oil pan.

Tightening Sequence For Oil Pan:

17. Tighten the bolts and nuts in the sequence shown, to 14 Nm (1.4 kg-m, 10 lb ft).

NOTE: Tighten the bolts and nuts in two steps and torque them in a criss-cross pattern.
