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

      Standard cylinder bore diameter
      10.285 to 10.306 mm (0.4049 to 0.4057 in.)

      If the bush bore diameter of the cylinder head is between 10.285 to 10.306 mm (0.4049 to 0.4057 in.), proceed to the next step.

      If the bush bore diameter of the cylinder head is 10.356 mm (0.4077 in.) or more, replace the cylinder head.

    5. Select a new guide bush (STD or O/S 0.05), and measure its diameter.

    6. Machine the bush bore diameter of the cylinder head side to the diameter of the selected guide bush.
