^ Driver attachment, 106 mm 070AD-RCA0200
1. Measure the diameter of each connecting rod bolt at point A and point B.
2. Calculate the difference in diameter between point A and point B.
Point A - Point B = Difference in Diameter
Difference in Diameter
Specification: 0 - 0.1 mm (0 - 0.004 in.)
3. If the difference in diameter is out of tolerance, replace the connecting rod bolt.
4. Check the connecting rod bearing clearance with plastigage.
5. Check the main bearing clearance with plastigage.
6. Install the bearing halves in the engine block and connecting rods.
7. Apply new engine oil to all the main bearing and rod bearing journals.
8. Lower the crankshaft (A) into the block.
9. Apply new engine oil to the thrust washer surfaces. Install the thrust washers (A) in the No. 3 journal.
10. Install the bearings (A) and bearing caps (B) with the arrow (C) facing the timing belt end of the engine.
11. Apply new engine oil to the bolt threads and flanges, then loosely install the bearing cap bolts (D) and bearing cap side bolts (E).
12. Set the crankshaft to bottom dead center (BDC) for the cylinder you are installing the piston in.
13. Remove the connecting rod cap. Install the ring compressor, and check that the bearing is securely in place.
14. Position the piston with the arrow (A) facing the timing belt side of the engine.
15. Position the piston in the cylinder, and tap it in using the wooden handle of a hammer (A). Maintain downward force on the ring compressor (B) to prevent the rings from expanding before entering the cylinder bore.
16. Stop after the ring compressor pops free, and check the connecting rod-to-crank journal alignment before pushing the piston into place.
17. Line up the mark (A) on the connecting rod and cap, then install the cap.
18. Apply new engine oil to the bolt threads. Torque the bolts (B) to 20 Nm (2.0 kgf-cm, 14 ft. lbs.).
19. Mark the connecting rod (A) and bolt head (B) as shown.
20. Tighten the bolt until the mark on the bolt head lines up with the mark on the connecting rod (turn the bolt 90°).
21. Tighten the bearing cap bolts (A), and then the bearing cap side bolts (B) to the specified torque in the sequence shown. Repeat the torque sequence again to assure the bolts are properly torqued.
22. The seal mating surface on the engine block end cover should be dry. Apply a light coat of multipurpose grease to the crankshaft and to the lip of the seal.
23. Drive the new crankshaft oil seal until the special tool bottoms on the engine block end cover.
24. Remove any old liquid gasket from the engine block end cover mating surfaces, bolts, and bolt holes.
25. Clean and dry the engine block end cover mating surfaces.
26. 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), new O-ring (B), and the engine block end cover (C) on the engine block.
NOTE: Do not install the parts if 4 minutes or more have elapsed since applying the liquid gasket. Instead, reapply liquid gasket after removing the old residue.
27. Remove any old liquid gasket from the oil pump mating surfaces, bolts, and bolt holes.
28. Clean and dry the oil pump mating surfaces.
29. Install the oil pump (A).
NOTE: Do not install the parts if 4 minutes or more have elapsed since applying the liquid gasket. Instead, reapply liquid gasket after removing the old residue.
30. Install the baffle plate (D), then install the oil screen (E).
31. Install the VTEC solenoid valve/oil filter assembly (A), with a new VTEC solenoid valve filter (B).
32. Install the oil pan.
33. Install the crankshaft position (CKP) sensor.
34. Install the cylinder heads.
35. Install the transmission:
^ Manual transmission.
^ Automatic transmission.
36. Install the engine assembly.
NOTE: When any crankshaft or connecting rod bearing is replaced, after assembly it is necessary to run the engine at idling speed until it reaches normal operating temperature, then continue to run it for about 15 minutes.
