Installation
CRANKSHAFT INSTALLATIONNOTE: Before installing the crankshaft, apply a coat of engine oil to the main bearings and rod bearings.
1. Insert the bearing halves into the cylinder block and connecting rods.
2. Hold the crankshaft so the rod journals for cylinders 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 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. Apply engine oil to the bolt threads.
Torque: 31 Nm (3.2 kgs.cm, 23 ft.lbs.)
NOTE: Reference numbers on connecting rod are for big-end bore tolerance and do not indicate the position of piston in the engine.
6. Install the thrust washers on the No. 4 journal. Oil the thrust washer surfaces.
7. Install the main bearing caps. Check clearance with plastigage, then tighten the bearing cap bolts in 2 steps.
First step: 25 Nm (2.5 kgs.cm, 18 ft.lbs.)
Second step: 51 Nm (5.2 kgs.cm, 38 ft.lbs.)
NOTE: Coat the bolt threads with oil.
- Use liquid gasket, part No. 08718-0001 or 08718-0003.
- 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 oil leakage, apply liquid gasket to the inner threads of the bolt holes.
- 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.
- After assembly, wait at least 20 minutes before filling the engine with oil.
8. Apply liquid gasket to the block mating surface of the right side cover, then install it on the cylinder block.
9. Apply liquid gasket to the oil pump mating surface of the block, then install the oil pump on the cylinder block.
NOTE: Do not apply liquid gasket to O-ring grooves. Apply a light coat of oil to the crankshaft and to the lip of the oil seal. Use new O-rings and apply oil when installing them.
10. Install the oil screen.
11. Apply liquid gasket on oil pump and right side cover mating areas.
12. Install the oil pan gasket and oil pan.
NOTE:
- Use a new oil pan gasket.
- Install oil pan no more than five minutes after liquid gasket applied.
13. Tighten nuts finger tight at six points as shown.
14. Tighten all bolts and nuts starting from nut 1 clockwise in three steps.
NOTE: Excessive tighting can cause distortion of the oil pan gasket and oil leakage.
