^ Holder handle 07JAB-001020A
^ Holder attachment, HEX 50 mm, offset 07MAB-PY3010A
^ Socket, 17 mm 07JAA-001010A or a commercially available 17 mm socket
1. Set the crankshaft sprocket so that the No.1 piston is at top dead center (TDC). Align the TDC mark (A) on the crankshaft purser plate with the pointer (B) on the cylinder block.
2. Install the cam chain with the colored piece (A) aligned with the punch mark (B) on the crankshaft sprocket.
3. Clean and dry the oil pump mating surfaces.
4. Apply liquid gaskets, part No. 08718-0009, evenly to the cylinder block mating surface of the oil pump and to the inner threads of the bolt holes.
NOTE: Do not install the parts if 5 minutes or more have elapsed since applying liquid gasket. Instead, reapply liquid gasket after removing the old residue.
5. Install the dowel pins (A), then align the inner rotor with the crankshaft and install the oil pump (B) using new O-rings (C).
6. Install the oil screen (D) using a new gasket (E).
7. Clean and dry the oil pan mating surfaces.
8. Apply liquid gasket part No. 08718-0009 evenly to the cylinder block mating surface of the oil pan and to the inner threads of the bolt holes.
NOTE: Do not install the parts if 5 minutes or more have elapsed since applying liquid gasket. Instead, reapply liquid gasket after removing the old residue.
9. Install the new oil pan gaskets (A) and a new O-ring (B) on the oil pan, then install the oil pan (C).
10. Tighten the bolts and nuts to the specified torque.
Specified torque:
8 x 1.25 mm
22 Nm (2.2 kgf-cm, 16 ft. lbs.)
6 x 1.0 mm
12 Nm (1.2 kgf-cm, 8.7 ft. lbs.)
11. Clean the bolt (A), washer (B), pulley (C) and, crankshaft (D).
12. Install the crankshaft pulley, and tighten the bolt to 20 Nm (2.0 kgf-m, 14 ft. lbs.).
13. Tighten the pulley bolt an additional 90°.
14. Clean the cylinder head and block surfaces.
15. Apply liquid gasket, part No. 08718-0009, to the shaded areas of the cylinder head gasket mating surface of the block and oil pump.
16. Install the dowel pins and new cylinder head gasket.
17. Apply liquid gasket, part No. 08718-0009, to the cylinder head mating surface of the block and oil pump along the broken line.
18. Install the cylinder head on the block.
19. Apply engine oil to the threads and under the heads of all the cylinder head bolts.
20. Tighten the cylinder head bolts in sequence to 39 Nm (4.0 kgf-cm, 29 ft. lbs.). Use a beam-type torque wrench. When using a preset-type torque wrench, be sure to tighten slowly and do not overtighten. If a bolt makes any noise while you are torquing it, loosen the bolt and retighten it.
21. Turn the cylinder head bolts 90°.
22. Tighten the 6 mm bolts to 12 Nm (1.2 kgf-cm, 8.7 ft. lbs.).
23. Make sure the crankshaft pulley is at TDC.
24. Place the camshaft sprocket into the cylinder head.
25. Install the cam chain on the camshaft sprocket with the punch mark (A) aligned with the colored piece (B).
26. Fit the camshaft sprocket on the camshaft.
27. Turn the camshaft sprocket counterclockwise to relieve cam chain free play, and check the alignment of the TDC mark (C) on the camshaft sprocket with the cylinder head surface. If the camshaft sprocket is not positioned at TDC, remove the camshaft sprocket from the camshaft, and reposition the cam chain to bring the camshaft sprocket to TDC.
28. Hold the camshaft with an open-end wrench, then tighten the camshaft sprocket mounting bolt.
29. Put the new cylinder head plug into the cylinder head.
30. Press the rod to pump the oil out of the timing chain auto-tensioner.
31. Install the new O-ring into the spacer. Set the spacer and new gasket on the cam chain auto-tensioner, then tighten the bolt and nuts equally while pressing the cam chain auto-tensioner against the cylinder head.
32. Adjust the valve clearance.
33. Install the cylinder head cover.
34. Install the engine oil cooler bypass hoses.
35. Tighten the idler pulley bracket mounting bolt.
36. Install the water pump.
37. Install the engine.
