a.
A301950

Using a caliper gauge, measure the intake valve guide bush bore diameter of the cylinder head sub-assembly.

Standard Bush Bore Diameter:

9.685 to 9.706 mm (0.3813 to 0.3821 in.)


New Guide Bush Selection Chart (STD or O/S 0.05):

9.735 to 9.755 mm (0.3833 to 0.3841 in.) O/S 0.05


HINT:

If the intake valve guide bush bore diameter of the cylinder head sub-assembly is greater than 9.706 mm (0.3821 in.), machine the intake valve guide bush bore to a diameter of 9.735 to 9.755 mm (0.3833 to 0.3841 in.) to install an O/S 0.05 intake valve guide bush. If the bush bore diameter of the cylinder head sub-assembly is greater than 9.755 mm (0.3841 in.), replace the cylinder head sub-assembly.



b.

Heat the cylinder head sub-assembly to 80 to 100°C (176 to 212°F).


c.

Place the cylinder head sub-assembly on wooden blocks.
