Cylinder Head Installation

Cylinder Head Installation





1. Measure the diameter of each cylinder head bolt at point A and point B. If either diameter is less than 11.5 mm (0.45 inch), replace the cylinder head bolt.
2. Clean and dry the cylinder head, engine block, and chain case mating surfaces.





3. Apply liquid gasket, P/N 08717-0004, 08718-0001, 08718-0003, or 08718-0009, to the shaded areas (A) of the cylinder head gasket mating surface of the engine block and chain case.

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.





4. Install the dowel pins (A) and the new cylinder head gasket (8).





5. Apply liquid gasket, P/N 08717-0004, 08718-0001, 08718-0003, or 08718-0009, to the cylinder head mating surface of the block and chain case within 5 mm of the edge of the cylinder head gasket.

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.

6. Install the cylinder head on the engine block.
7. Apply new engine oil to the threads and flange of all the cylinder head bolts.





8. Tighten the cylinder head bolts in sequence to 29 Nm (3.0 kgf-m, 22 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.
9. Tighten all cylinder head bolts in two steps (90° per step). If you are using a new cylinder head bolt, tighten the bolt an extra 90°.
10. Tighten the 8 mm bolts (A) to 22 Nm (2.2 kgf-m, 16 ft. lbs.).





11. Make sure the crankshaft pulley is at top dead center (TDC). Align the TDC mark (A) on the crankshaft pulley with the pointer (B) on the chain case.





12. Assemble the idler gear (A) and cam chain sprocket (B) with three mounting bolts (C). Torque the bolts to 13 Nm (1.3 kgf-m, 9.4 ft. lbs.).
13. Place the idler gear/cam chain sprocket assembly and idler gear collar into the cylinder head.
14. Install-the cam chain on the sprocket, then fit the assembly into the cylinder head.





15. Turn the idler gear counterclockwise to relieve cam chain free play, and check the alignment of the TDC marks (A) on the cam chain sprocket with the cylinder head surface. If the cam chain sprocket is not positioned at TDC, remove the idler gear from the cylinder head and reposition the cam chain to bring the cam chain sprocket to TDC.





16. Apply new engine oil to the idler gear/cam chain sprocket center bolt threads (A). Install a new O-ring (B) on the bolt.
17. Install the washer (C) on the idler gear, and tighten the center bolt.
18. Clamp the cam chain auto-tensioner in a soft-jawed vise.





19. Turn the 5 x 0.8 mm bolt (A) clockwise to compress the bottom of the auto-tensioner, then insert the set pin (B), P/N 14511-PCX-005.





20. Remove the 5 x 0.8 mm bolt from the maintenance hole. Install a new O-ring (A), then install the nozzle (B) and end cover (C).





21. Install the cam chain auto-tensioner (A) in the cylinder head with new O-rings (B).
22. Remove the maintenance bolt (C) from the cylinder head.





23. Remove the set pin (A) from the cam chain auto-tensioner. Reinstall the maintenance bolt (B) with a new washer (C).





24. Insert the bolts (A) into the rocker shaft holder, then install the rocker arm assembly (B).





25. Check the alignment of the TDC marks (A) on the cam chain sprocket with the cylinder head surface.
26. Align the TDC marks (B) on the intake camshaft gear (C) and the exhaust camshaft gear (D), and install the camshafts.
27. Apply new engine oil to the bolt threads of all the camshaft holder bolts.





28. Put the camshaft holders on the cylinder head, then tighten all bolts to 22 Nm (2.2 kgf-m, 16 ft. lbs.). To prevent damaging the camshafts, tighten the bolts two turns at a time, in the sequence shown.





29. Make sure the camshaft gears are at TDC.
30. Adjust the valve clearance.
31. Install the cylinder head cover.





32. Install the intake manifold (A) with a new gasket (B), then install the intake manifold stay.
33. 2000-2005 models: Install the injectors.





34. Install the exhaust manifold (A) using new gaskets (B) and new self-locking nuts (C).
35. Install the exhaust manifold bracket (D). Make sure the smooth sides of the washers (E) face the exhaust manifold bracket.
36. Put the exhaust manifold cover on the exhaust manifold.





37. Install the heat shield.





38. Tighten the four bolts securing the exhaust manifold cover.
