Before installation of the cylinder head assembly, be sure the 4D-0514 Plug is installed at location (X). |
14. Attach tooling (B), and a hoist to cylinder head assembly (10). Put the cylinder head assembly in position.
15. Put clean engine oil on the threads of the cylinder head bolts (11). Install the cylinder head bolts and washers. Tighten the bolts in the following sequence.
a. Tighten all of the bolts to a torque of 30 ± 5 N·m (22 ± 4 lb ft).
b. Tighten bolts 1 through 8 in number sequence to a torque of 270 ± 35 N·m (200 ± 26 lb ft).
c. Tighten bolts 1 through 8 in number sequence to a torque of 450 ± 20 N·m (330 ± 15 lb ft).
15a. Tighten the two 3/8 inch bolts (12) to a torque of 55 ± 10 N·m (40 ± 7 lb ft).
16. Install the O-ring seals, the gasket, and valve cover base (7).
NOTE: Install the lever assembly and rod assembly (8) as a unit when installing the fuel injector.
17. Install the fuel injector. See the topic, Install Fuel Injector.
18. Connect rod assembly (8) to the fuel control shaft and install cap (9), the bolt and the access cover.
19. Install the gasket and inlet elbow (5).

Tighten the individual exhaust manifold section to the cylinder head first. Then, tighten the individual exhaust manifold section to the other manifold sections. This procedure will prevent exhaust manifold damage caused by misalignment. |
20. Install the gasket and exhaust manifold section (4).
21. Install the gasket and elbow (6).
22. Install the gaskets and water manifold section (1).
23. Install fuel manifold (3) and connect fuel lines (2).
24. Turn on the fuel supply.
25. Fill the cooling system with coolant to the correct level. See the Maintenance Manual.
