1. Insert thrust washers onto journal No.4 of the cylinder block.
2. Insert the bearing shells into the cylinder block bed and onto the connecting rods.
3. Hold the crankshaft so that the crankpins for cylinders No.2 and No.3 are at the bottom.
4. Lower the crankshaft into the cylinder block bed, seating the crankpins in connecting rods No.2 and No.3, install the caps and tighten the nuts by hand.
5. Turn the crankshaft clockwise, seat the journals in connecting rods No.1 and No.4, install the caps and tighten the nuts by hand.
Note: Install the caps so that the recesses in the bearings are on the same side as the recesses in the connecting rods.
6. Check the connecting rod bearing clearance using a Plastigage gauge (see above), then tighten the cover nuts to 31 Nm (3.2 kgf/m). Apply engine oil to the bolt threads.
Note: The reference numbers on the connecting rods indicate the diameter of the big end of the connecting rod and have no bearing on the location of the piston in the engine.
7. Install the thrust washers on journal No.4. Lubricate the surfaces of the thrust washers with oil.
8. Install the main bearing caps.
9. Check the gap using a calibrated Plastigage wire (see above), then tighten the bearing cap bolts in two passes.
- 1st pass: 25 Nm (2.5 kgf/m)
- 2nd pass: 51 Nm (5.2 kgf/m)
Note: Apply oil to the surfaces of the thrust washers and the threads of the bolts.
Note: If you replace the main or connecting rod bearing, after assembly, let the engine run at idle speed until it warms up to normal operating temperature, then for about 15 more minutes.
Note:
- Use sealant P/N 08C70-K0234M, 08C70-K0334M or 08C70-X0331S.
- Before applying sealant, ensure that the contact surfaces are clean and dry.
- Apply the sealant evenly, distributing it over the entire contact surface.
- To prevent oil leakage, apply sealant to the threads of the bolt holes.
- Do not install components if more than five minutes have passed since applying the sealant. Instead, reapply the sealant, removing any traces of the old one.
- After assembly, wait at least 30 minutes before adding oil to the engine.
10. Apply sealant to the contact surface of the cylinder block on the right cover side, then install it on the cylinder block.
1. Apply sealant along the dotted line.
2. RIGHT COVER
3. RIGHT COVER
