Using a caliper gauge, measure the bush bore diameter of the cylinder head.

Select a new guide bush.

• New Guide Bush:

• Item	Specified Conditions
  Bush Bore Diameter	13.004 to 13.025 mm (0.512 to 0.513 in.)	13.054 to 13.075 mm (0.514 to 0.515 in.)
  Bush to be Used	STD	O/S 0.05

If the bush bore diameter of the cylinder head is more than 13.025 mm (0.513 in.), machine the bush bore to a dimension of 13.054 to 13.075 mm (0.514 to 0.515 in.).

If the bush bore diameter of the cylinder head is more than 13.075 mm (0.515 in.), replace the cylinder head.

Gradually heat the cylinder head to approximately 80 to 100°C (176 to 212°F).

Using SST and a hammer, tap in a new guide bush to the specified protrusion height.
