PROCEDURE

  1. REPLACE INTAKE VALVE GUIDE BUSH

    1. Heat the cylinder head sub-assembly to between 80 and 100°C (176 and 212°F).

    2. Using SST and a hammer, tap out the intake valve guide bush to the combustion chamber side.

      09950-70010
    3. Using a caliper gauge, measure the intake valve guide bush bore diameter of the cylinder head sub-assembly.

      A012HZO
      Standard bush bore diameter
      10.985 to 11.006 mm (0.4325 to 0.4333 in.)
      Tip:
      • If the intake valve guide bush bore diameter is as specified, install a standard intake valve guide bush.

      • If the intake valve guide bush bore diameter is not as specified, machine the bush bore to 11.035 to 11.056 mm (0.4345 to 0.4353 in.) and install an oversize intake valve guide bush.

        Bush Size Bush Bore Diameter mm (in.)
        Standard Standard 10.985 to 11.006 (0.4325 to 0.4333)
        Oversize (0.05) Oversize 11.035 to 11.056 (0.4344 to 0.4353)
    4. Heat the cylinder head sub-assembly to between 80 and 100°C (176 and 212°F).

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

      09201-10000   ( 09201-01050 )
      09950-70010
      Standard protrusion height
      15.9 to 16.7 mm (0.626 to 0.657 in.)
    6. Using a reamer, ream the inside of the intake valve guide bush to obtain the specified oil clearance.

      A012JT6
      Standard oil clearance
      0.025 to 0.060 mm (0.000984 to 0.00236 in.)
  2. REPLACE EXHAUST VALVE GUIDE BUSH

    1. Heat the cylinder head sub-assembly to between 80 and 100°C (176 and 212°F).

    2. Using SST and a hammer, tap out the exhaust valve guide bush to the combustion chamber side.

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

      A012FSB
      Standard bush bore diameter
      10.985 to 11.006 mm (0.4325 to 0.4333 in.)
      Tip:
      • If the exhaust valve guide bush bore diameter is as specified, install a standard exhaust valve guide bush.

      • If the exhaust valve guide bush bore diameter is not as specified, machine the bush bore to 11.035 to 11.056 mm (0.4344 to 0.4353 in.) and install an oversize exhaust valve guide bush.

        Bush Size Bush Bore Diameter mm (in.)
        Standard Standard 10.985 to 11.006 (0.4325 to 0.4333)
        Oversize (0.05) Oversize 11.035 to 11.056 (0.4344 to 0.4353)
    4. Heat the cylinder head sub-assembly to between 80 and 100°C (176 and 212°F).

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

      Standard protrusion height
      15.9 to 16.7 mm (0.626 to 0.657 in.)
    6. Using a reamer, ream the inside of the exhaust valve guide bush to obtain the specified oil clearance.

      Standard oil clearance
      0.030 to 0.065 mm (0.00118 to 0.00256 in.)
  3. REPLACE RING PIN

    1. Remove the 4 ring pins shown in the illustration.

    2. Using a plastic-faced hammer, tap in 4 new ring pins to the specified protrusion height.
