2. Remove bolts (1). 3. Disconnect air hose (2) from the cylinder head to the air compressor.4. Remove air compressor inlet tube (3).5. Disconnect the air tube from the inlet manifold to the fuel ratio control. 6. Remove oil inlet tube (4).7. Remove two bolts (5). 8. Remove the bolts that hold the cylinder head to the cylinder block.9. Fasten a hoist to the cylinder head. Carefully remove the head from the block. Weight is 164 lb. (74.4 kg).Install Cylinder Head
1. Install a new, dry cylinder head gasket.2. Fasten a hoist to the cylinder head and put the cylinder head in position on the cylinder block.3. Install the push rods. Put the rocker shaft in position on the engine.
Dowel pins (A) on each end of the rocker shaft assembly must be in alignment with holes (B). If the pins and holes are not in alignment during installation of the rocker shaft assembly, damage to the rocker shaft assembly will be the result.
4. Put 5P3931 Anti-Seize Compound on the threads of cylinder head and rocker shaft bolts. Install the bolts in the following step sequence: 1. Tighten all bolts in number sequence to a torque of 115 lb. ft. (155 N m).2. Tighten all bolts in number sequence to a torque of 185 13 lb. ft. (250 17 N m).3. Tighten all bolts in number sequence (hand turn only) to a torque of 185 13 lb. ft. (250 17 N m) again.4. Tighten all bolts (hand turn only) in letter sequence to a torque of 32 5 lb. ft. (43 7 N m). 5. Make an adjustment to the valves to get a clearance of .015 in. (0.38 mm) for the intake valves and .025 in. (0.64 mm) for the exhaust valves.6. Install the turbocharger oil inlet tube. Install the two bolts that connect the oil outlet tube to the turbocharger.7. Connect the air tube from the fuel ratio control to the inlet manifold.8. Connect the air hose from the air compressor to the cylinder head.9. Install the two bolts removed from the temperature regulator.10. Fill the cooling system with coolant to the correct level.end by:a) install fan driveb) install fuel injection lines
