PROCEDURE


  1. REPLACE INTAKE VALVE GUIDE BUSH

    Note

    The standard protrusion amount (A) of the valve guide bush determines whether the cylinder head is type A or B. Therefore, measure the standard protrusion amount (A) before removing the valve guide bush.

    A00190XN01
    Standard Protrusion Height (A)
    Type Specified Condition
    Cylinder Head Type A 14.3 to 14.7 mm (0.563 to 0.579 in.)
    Cylinder Head Type B 15.8 to 16.2 mm (0.622 to 0.638 in.)

    1. Heat the cylinder head to approximately 80 to 100°C (176 to 212°F).

    2. Place the cylinder head on wooden blocks.

    3. A001EIRE01

      Using SST and a hammer, tap out the valve guide bush.

      SST
      09201-10000   ( 09201-01050 )
      09950-70010   ( 09951-07100 )
    4. A001C4O

      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.

      Cylinder Head Type B 15.8 to 16.2 mm (0.622 to 0.638 in.)

      Note

      Install the valve guide bush after determining cylinder head type A and B.

    9. A001FXG

      Using a sharp 5.5 mm reamer, ream the guide bush to obtain the standard specified clearance between the guide bush and valve stem.

  2. REPLACE EXHAUST VALVE GUIDE BUSH

    Note

    The standard protrusion amount (A) of the valve guide bush determines whether the cylinder head is type A or B. Therefore, measure the standard protrusion amount (A) before removing the valve guide bush.

    A00190XN01
    Standard Protrusion Height (A)
    Type Specified Condition
    Cylinder Head Type A 14.3 to 14.7 mm (0.563 to 0.579 in.)
    Cylinder Head Type B 15.8 to 16.2 mm (0.622 to 0.638 in.)

    1. Heat the cylinder head to approximately 80 to 100°C (176 to 212°F).

    2. Place the cylinder head on wooden blocks.

    3. A001C1GE01

      Using SST and a hammer, tap out the valve guide bush.
