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).
