Fasten tool (C) to the exhaust manifold and the hoist. Remove cylinder head assembly (11). The weight of the cylinder head assembly is 205 kg (455 lb.).Install Cylinder Head Assembly
1. Clean the machined surfaces of the cylinder head and cylinder block that make contact with the cylinder head gasket. 2. Put a new cylinder head gasket in position on the cylinder block. Make sure the holes in the cylinder head gasket are all in alignment with the holes in the cylinder block. Fasten a hoist to cylinder head assembly (1) and put it in position on the cylinder block. 3. Install the push rods. Put the rocker shaft in position on the cylinder head.
Make sure the dowels in the rocker shaft assembly are in alignment with the holes in the cylinder head before the bolts are installed and tightened.
4. Put 5P3931 Anti-Seize Compound on the threads of the cylinder head bolts and rocker shaft bolts. Install the bolts and washers and tighten the bolts as follows: a) Tighten all the bolts in number sequence to a torque of 155 N m (115 lb. ft.).b) Tighten all bolts in number sequence to a torque of 250 17 N m (185 13 lb. ft.).c) Tighten all bolts in number sequence (hand turn only) to a torque of 250 17 N m (185 13 lb. ft.).d) Tighten all bolts in letter sequence to a torque of 28 N m (22 lb. ft.).e) Tighten all bolts in letter sequence to a torque of 43 7 N m (32 5 lb. ft.).f) Tighten all bolts in letter sequence (hand turn only) to a torque of 43 7 N m (32 5 lb. ft.). 5. Make adjustments until the intake valve clearance is 0.38 mm (.015 in.) and the exhaust valve clearance is 0.64 mm (.025 in.). See VALVE CLEARANCE SETTING in TESTING AND ADJUSTING.6. Install the valve cover. See Install Valve Cover.7. Fasten a hoist to the fan drive and remove it from tool (A). Remove tool (A) from the front of the cylinder block and fasten the fan drive to the cylinder head. Make an adjustment to the vee belt tension. See V-Belt tension chart in the Specifications. 8. Install bracket (3) for the refrigerant compressor.9. Install inlet tube assembly (6) and return tube assembly (4) for the turbocharger.10. Put the wire harness for the glow plugs in position and install clip (5). Connect the wires to the glow plugs.11. Install bracket (2).12. Install the two bolts that hold the housing for the water pump to the cylinder head.13. Install the two bolts that hold the bracket for the transmission oil filter to the cylinder head.14. Install the water temperature sensing line in the cylinder head.15. Slide the hose for the inlet elbow for the radiator in position. Tighten the two clamps that hold it.16. Fill the cooling system with coolant to the correct level.
