START BY:a. remove exhaust manifoldb. remove rocker shaft assembly and push rodsc. remove fuel injection nozzles * 1. Loosen hose clamp (2), and remove tube assembly (1) between the cylinder head assembly and the timing gear cover. 2. Remove 22 bolts (3) that hold the cylinder head assembly to the cylinder block. 3. Fasten tool (A) and a hoist to the cylinder head assembly. Remove the cylinder head assembly from the cylinder block. Weight of the cylinder head assembly is 57 kg (125 lb.).4. Remove the cylinder head gasket, water ferrule and seal from the cylinder block.*The fuel injection nozzles do not have to be removed from the cylinder head assembly when the cylinder head assembly is removed from the cylinder block. If the fuel injection nozzles are not removed, do not put the cylinder head assembly down on a flat surface. This can cause damage to the fuel injection nozzles. Install Cylinder Head Assembly
Check the cylinder head and block for top deck flatness. The flatness of the cylinder head and block should be within 0.15 mm (.006") total, and a maximum of 0.08 mm (.003") for any 152.4 mm (6.00") span.1. Check the condition of the water ferrule and seal (4). Make a replacement if needed. Put the water ferrule and seal (4) in position with the adjusting screw of hose clamp (2) toward the top and approximately 45° to the right of vertical line as seen from the front of the engine. Make sure the seal is installed all the way into the counterbore.2. Clean the surfaces of the cylinder head assembly and the cylinder block that make contact with each other.

Put 5P960 Multipurpose Type Grease on the threads of all the cylinder head bolts. 5. Install the cylinder head bolts, and tighten them as follows: a. Tighten bolts 1 through 18 in the number sequence shown to a torque of 81.5 13 N m (60 10 lb.ft.).b. Tighten bolts 1 through 18 in number sequence to a torque of 149 6.5 N m (110 5 lb.ft.).c. Tighten bolts 1 through 18 again in number sequence to a torque of 149 6.5 N m (110 5 lb.ft.).d. Tighten bolts 19 through 22 in number sequence to a torque of 43.5 6.5 N m (32 5 lb.ft.). 6. Install tube assembly (5) between the cylinder head assembly and the timing gear cover. Tighten hose clamp (6).END BY:a. install fuel injection nozzlesb. install rocker shaft assembly and push rodsc. install exhaust manifoldDisassemble Cylinder Head Assembly
