PROCEDURE


  1. REPLACE INTAKE VALVE GUIDE BUSH


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

    2. A01SCU4N01

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

      SST
      09201-10000   ( 09201-01080 )
      09950-70010   ( 09951-07100 )

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

    4. Select a new intake valve guide bush.

      New Guide Bush
      Item Specified Condition
      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 valve guide bush bore diameter of the cylinder head sub-assembly is more than 13.025 mm (0.513 in.), machine the valve guide bush bore diameter to between 13.054 and 13.075 mm (0.514 and 0.515 in.).

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

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

    6. A01SBYAN01

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

      SST
      09950-70010   ( 09951-07100 )
      09201-10000   ( 09201-01070 )
      Standard protrusion height (H)
      10.8 to 11.2 mm (0.425 to 0.441 in.)
    7. A01SAODC02
      *a Sharp 8.0 mm Reamer

      Using a sharp 8.0 mm reamer, ream the intake valve guide bush to obtain the standard clearance between the intake valve guide bush and valve stem.

      Standard clearance
      0.02 to 0.055 mm (0.000787 to 0.00217 in.)

  2. REPLACE EXHAUST VALVE GUIDE BUSH


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

    2. A01SCL7N01

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

      SST
      09201-10000   ( 09201-01080 )
      09950-70010   ( 09951-07100 )

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

    4. Select a new exhaust valve guide bush.

      New Guide Bush
      Item Specified Condition
      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 valve guide bush bore diameter of the cylinder head sub-assembly is more than 13.025 mm (0.513 in.), machine the valve guide bush bore diameter to between 13.054 and 13.075 mm (0.514 and 0.515 in.).

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

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

    6. A01SD8ZN01

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

      SST
      09950-70010   ( 09951-07100 )
      09201-10000   ( 09201-01070 )
      Standard protrusion height (H)
      10.8 mm to 11.2 mm (0.425 to 0.441 in.)
    7. A01SEYWC01
      *a Sharp 8.0 mm Reamer

      Using a sharp 8.0 mm reamer, ream the exhaust valve guide bush to obtain the standard clearance between the exhaust valve guide bush and valve stem.

      Standard clearance
      0.035 to 0.07 mm (0.00138 to 0.00276 in.)

  3. REPLACE TIGHT PLUG

    Tech Tips

    It is not necessary to remove a tight plug unless it is being replaced.


    1. Remove the tight plugs.

    2. Apply adhesive to new tight plugs.

      Adhesive
