PROCEDURE


  1. REPLACE INTAKE VALVE GUIDE BUSH


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

    2. Place the cylinder head sub-assembly on wooden blocks.

    3. A01IEJIN07

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

      09950-70010   ( 09951-07100 )
    4. A01IK1S

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

      Standard Intake Valve Guide Bush Bore Diameter
      10.285 to 10.306 mm (0.405 to 0.406 in.)
      New Guide Bush Selection Chart
      Bush Size Specified Condition
      STD 10.333 to 10.344 mm (0.40681 to 0.40724 in.)
      O/S 0.05 10.383 to 10.394 mm (0.40878 to 0.40921 in.)
      Standard Bush Length
      41.3 to 41.7 mm (1.63 to 1.64 in.)

      If the intake valve guide bush bore diameter of the cylinder head sub-assembly is more than 10.306 mm (0.406 in.), machine the intake valve guide bush bore of the cylinder head sub-assembly to a dimension of 10.335 to 10.356 mm (0.407 to 0.408 in.) to install an O/S 0.05 intake valve guide bush.

      If the intake valve guide bush bore diameter of the cylinder head sub-assembly is more than 10.356 mm (0.408 in.), replace the cylinder head sub-assembly.

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

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

      SST
      09201-10000   ( 09201-01050 )
      09950-70010   ( 09951-07100 )
      Standard Protrusion Height
      14.8 to 15.2 mm (0.583 to 0.598 in.)
    7. A01IJYQ

      Using a sharp 5.5 mm reamer, ream the intake valve guide bush to obtain the standard oil clearance.

      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 to 212°F).

    2. Place the cylinder head sub-assembly on wooden blocks.

    3. A01IG3ZN01

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

      09950-70010   ( 09951-07100 )
    4. A01IIN9

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

      Standard Exhaust Valve Guide Bush Bore Diameter
      10.285 to 10.306 mm (0.405 to 0.406 in.)
      New Guide Bush Selection Chart
      Bush Size Specified Condition
      STD 10.333 to 10.344 mm (0.40681 to 0.40724 in.)
      O/S 0.05 10.383 to 10.394 mm (0.40878 to 0.40921 in.)
      Standard Bush Length
      46.8 to 47.2 mm (1.84 to 1.86 in.)

      If the exhaust valve guide bush bore diameter of the cylinder head sub-assembly is more than 10.306 mm (0.406 in.), machine the exhaust valve guide bush bore of the cylinder head sub-assembly to a dimension of 10.335 to 10.356 mm (0.407 to 0.408 in.) to install an O/S 0.05 exhaust valve guide bush.

      If the exhaust valve guide bush bore diameter of the cylinder head sub-assembly is more than 10.356 mm (0.408 in.), replace the cylinder head sub-assembly.

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