CYLINDER HEAD REPLACEMENT

PROCEDURE


  1. REMOVE INTAKE VALVE GUIDE BUSH


    1. A005H0F

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

    2. A005KAZE01

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

      SST
      09201-10000   ( 09201-01050 )
      09950-70010   ( 09951-07100 )

  2. REMOVE EXHAUST VALVE GUIDE BUSH


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

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

      SST
      09201-10000   ( 09201-01050 )
      09950-70010   ( 09951-07100 )

  3. INSTALL INTAKE VALVE GUIDE BUSH


    1. A005GFX

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

      Inside diameter
      10.285 to 10.306 mm (0.4050 to 0.4057 in.)

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

    3. A005I9EE02
      *1 9.4 to 9.8 mm

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

      SST
      09201-10000   ( 09201-01050 )
      09950-70010   ( 09951-07100 )
      Protrusion height
      9.4 to 9.8 mm (0.370 to 0.386 in.)
    4. A005GQ5E02
      Text in Illustration
      *1 Reamer

      Using a sharp 5 mm reamer, ream the intake valve guide bushing to obtain the standard oil clearance between the intake valve guide bushing and valve stem.

      Standard oil clearance
      0.025 to 0.060 mm (0.0010 to 0.0024 in.)

  4. INSTALL EXHAUST VALVE GUIDE BUSH


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

      Inside diameter
      10.285 to 10.306 mm (0.4050 to 0.4057 in.)

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

    3. Using SST and a hammer, tap a new exhaust valve guide bushing in to the specified protrusion height.

      SST
      09201-10000   ( 09201-01050 )
      09950-70010   ( 09951-07100 )
      Protrusion height
      9.4 to 9.8 mm (0.370 to 0.386 in.)

    4. Using a sharp 5 mm reamer, ream the exhaust valve guide bushing to obtain the standard oil clearance between the exhaust valve guide bushing and valve stem.

      Standard oil clearance
      0.030 to 0.065 mm (0.0012 to 0.0026 in.)
