KRYOTEC ENGINE 156 69. Install the 1860815000 crankshaft rotation tool. 70. Install the crankshaft pulley, hold the crankshaft rotation tool and tighten the bolt to the proper (Torque Specifi- cations). 71. Remove the 1860815000 crankshaft rotation tool. 72. Measure the protrusion of the pistons at two points 180° apart, on the axis of the pin with the tool and take the average of the two readings for each piston. 73. Choose the thickness of the cylinder head gasket to be used, as a function of the maximum value between the averages of the protrusion of the pistons (Refer to 09 - Engine/Specifications). 74. Bring the first cylinder to TDC and further rotate the crankshaft counterclockwise the equivalent of two teeth on the crankshaft sprocket to lower the piston thus avoiding any interference with the valves during the installation of the cylinder head. NOTE The engine block to cylinder head centering bushings are shorter (12.5 mm) compared to the cylinder head to cylinder head cover centering bushings, so be careful not to reverse them as engine damage may occur. 75. Install the cylinder head centering bushings in the engine block. 76. Install the NEW selected cylinder head gasket. 77. Install the cylinder head. NOTE The cylinder head bolts can not be reused more than four times due to elongation which occurs with each use. In case you do not know the number of uses performed previously on the cylinder head bolts, it is imperative that they be replaced. 78. Tighten the cylinder head bolts (1a) in the sequence shown using a suitable angle tightening tool (1b) to the proper (Torque Specifications). 79. Install the glow plugs and tighten to the proper (Torque Specifications).
