  4. INSTALL INTAKE VALVE GUIDE BUSH

    A01E0FLE01

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

      Select a new guide bush (STD or O/S 0.05)
      Bush Size Bush Bore Diameter
      Use STD 10.985 to 11.006 mm (0.4325 to 0.4333 in.)
      Use O/S 0.05 11.035 to 11.056 mm (0.4344 to 0.4353 in.)

      If the bush bore diameter of the cylinder head is greater than 11.006 mm (0.4333 in.), machine the bush bore diameter to between 11.035 to 11.056 mm (0.4344 to 0.4353 in.).

      If the bush bore diameter of the cylinder head is greater than 11.056 mm (0.4353 in.), replace the cylinder head.

    2. A01DX1ZE01

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

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

      SST
      09201-10000   ( 09201-01060 )
      09950-70010   ( 09951-07100 )
      Standard protrusion height (H)
      10.3 to 10.7 mm (0.406 to 0.421 in.)
    4. A01DW47E01

      Using a sharp 6.0 mm reamer, ream the guide bush to obtain the standard specified clearance between the guide bush and valve stem.

  5. INSTALL EXHAUST VALVE GUIDE BUSH

    A01E10XE01

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

      Select a new guide bush (STD or O/S 0.05)
      Bush Size Bush Bore Diameter
      Use STD 10.985 to 11.006 mm (0.4325 to 0.4333 in.)
      Use O/S 0.05 11.035 to 11.056 mm (0.4344 to 0.4353 in.)

      If the bush bore diameter of the cylinder head is greater than 11.006 mm (0.4333 in.), machine the bush bore diameter to between 11.035 to 11.056 mm (0.4344 to 0.4353 in.).

      If the bush bore diameter of the cylinder head is greater than 11.056 mm (0.4353 in.), replace the cylinder head.

    2. A01DWECE01

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

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

      SST
      09201-10000   ( 09201-01060 )
      09950-70010   ( 09951-07100 )
      Standard protrusion height (H)
      10.3 to 10.7 mm (0.406 to 0.421 in.)
    4. A01E2B3E01

      Using a sharp 6.0 mm reamer, ream the guide bush to obtain the standard specified clearance between the guide bush and valve stem.

  6. INSTALL VALVE STEM OIL SEAL

    A01DZ0WE01

    1. Using SST, push in a new oil seal.
