Install the cylinder head in the reverse order of removal, taking into account the following:

• before installing the cylinder head on the cylinder block, align the TDC mark on the flywheel with the installation protrusion in the clutch housing hatch;
• if necessary, measure the piston protrusion relative to the plane of the cylinder block, calculate the arithmetic mean value and determine the thickness of the cylinder head gasket in accordance with Table 3-7;
• turn the crankshaft counterclockwise so that the pistons of all cylinders are approximately at the same level;
• install the cylinder head, tighten the mounting bolts by hand and tighten them using the specified techniques and in the specified order (Fig. 3-11).
