Typical Example1. Remove bolts (1) from the alternator bracket.2. Remove the bolts that hold plate (3) and remove the plate.3. Disconnect water line (2) from the air compressor. Turn the water line tee toward the lifting bracket in order to provide clearance to remove the head bolt. 4. Remove bolts (4) and (5) that hold the cylinder head assembly to the cylinder block.5. Fasten a hoist and remove the cylinder head assembly. The weight is approximately 135 kg (300 lb).
Do not put the cylinder head assembly down on a flat surface. This can cause damage to the fuel injection valves.
6. Remove the gasket and seals from the spacer plate.Install Cylinder Head Assembly
Be sure a new gasket has been installed between the spacer plate and the cylinder block. See topic, "Remove & Install Spacer Plate". 1. Thoroughly clean the spacer plate and the bottom surface of the cylinder head assembly. Install a new head gasket, new seals (1) and two O-ring seals (2). 2. Fasten a hoist and pit the cylinder head assembly (3) in position on the cylinder block.3. Put clean engine oil on the threads of the cylinder head bolts. Install the cylinder head bolts and washers. Tighten the bolts in sequence shown in Illustration 88255P3. a. Tighten bolts 1 through 20 in number sequence to a torque of 270 25 N m (200 18 lb ft).b. Tighten bolts 1 through 20 in number sequence to a torque of 450 20 N m (330 15 lb ft).c. Tighten bolts 1 through 20 in number sequence to a torque of 450 20 N m (330 15 lb ft) by hand.d. Install the rocker shaft assemblies and push rods. See topic, "Install Rocker Shaft Assemblies And Push Rods".e. Tighten bolts 21 through 26 in number sequence to a torque of 270 25 N m (200 18 lb ft).f. Tighten bolts 21 through 26 in number sequence to a torque of 450 20 N m (330 15 lb ft).g. Tighten bolts 21 through 26 in number sequence to a torque of 450 20 N m (330 15 lb ft) by hand.h. Tighten the 3/8 in bolts to a torque of 43 7 N m (32 5 lb ft). If the studs for the exhaust manifold were removed, install new studs, and tighten them to a torque of 25 4 N m (18 3 lb ft).4. Make an adjustment to the valves to have a clearance of 0.38 mm (.015 in) for intake and 0.76 mm (.030 in) for exhaust. Tighten the locknuts for the valve adjustment screws to a torque of 28 4 N m (21 3 lb ft).5. Install the valve cover bases and the inner fuel lines. See topic, "Install Rocker Shaft Assemblies And Push Rods".6. Install the valve covers. See topic, "Install Valve Covers".
