  1. REMOVE INTAKE VALVE GUIDE BUSH

    A01EVI8E01

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

    2. Place the cylinder head on wooden blocks.

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

  2. REMOVE EXHAUST VALVE GUIDE BUSH

    A01ETPQE03

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

    2. Place the cylinder head on wooden blocks.

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

  3. INSTALL INTAKE VALVE GUIDE BUSH

    A01EYL0

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

      Standard cylinder bore diameter
      10.285 to 10.306 mm (0.4049 to 0.4057 in.)
      Select a New Guide Bush (STD or O/S 0.05)
      Bush Size Bush Bore Diameter
      Use STD 10.333 to 10.344 mm (0.4068 to 0.4072 in.)
      Use O/S 0.05 10.383 to 10.394 mm (0.4088 to 0.4092 in.)

      If the cylinder head bush bore diameter is greater than 10.306 mm (0.4057 in.), machine the bush bore to a dimension of 10.335 to 10.356 mm (0.4069 to 0.4077 in.) and install an O/S 0.05 valve guide bush. If the bush bore diameter of the cylinder head is greater than 10.356 mm (0.4077 in.), replace the cylinder head.

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

    3. Place the cylinder head on wooden blocks.

      *a Protrusion Height

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

      SST
      09201-10000   ( 09201-01050 )
      09950-70010   ( 09951-07100 )
      Standard protrusion height
      9.6 to 10.0 mm (0.3779 to 0.3937 in.)
    5. A01ETFL

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

      Standard oil clearance
      0.025 to 0.060 mm (0.000984 to 0.00236 in.)

  4. INSTALL EXHAUST VALVE GUIDE BUSH

    A01EXBF

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

      Standard cylinder bore diameter
      10.285 to 10.306 mm (0.4049 to 0.4057 in.)
      Select a New Guide Bush (STD or O/S 0.05)
      Bush Size Bush Bore Diameter
      Use STD 10.333 to 10.344 mm (0.4068 to 0.4072 in.)
      Use O/S 0.05 10.383 to 10.394 mm (0.4088 to 0.4092 in.)

      If the cylinder head bush bore diameter is greater than 10.306 mm (0.4057 in.), machine the bush bore to a dimension of 10.335 to 10.356 mm (0.4069 to 0.4077 in.) and install an O/S 0.05 valve guide bush. If the bush bore diameter of the cylinder head is greater than 10.356 mm (0.4077 in.), replace the cylinder head.

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