Replacement [12/2012 - ]: Procedure

  1. REPLACE INTAKE VALVE GUIDE BUSH 
    1. Heat the cylinder head to approximately 80 to 100°C (176 to 212°F).
    2. Place the cylinder head on wooden blocks.
    3. Using SST and a hammer, tap out the valve guide bush.

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

      Standard bush bore diameter

      10.285 to 10.306 mm (0.405 to 0.406 in.)

      If the bush bore diameter of the cylinder head is between 10.285 and 10.306 mm (0.405 and 0.406 in.), proceed to the next step.

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

    5. Select a new guide bush (STD or O/S 0.05) and measure its diameter.
    6. Machine the bush bore of the cylinder head to the diameter of the selected guide bush.

      *1 Adhesive
      *2 Application Width
      *3 Distance

      Adhesive

      Distance

      6.0 mm (0.236 in.)

      NOTE:
      • Install the spark plug tube within 3 minutes after applying adhesive.
      • Be careful not to deform the spark plug tube.
      • Be careful not to expose the seal to coolant for at least 1 hour after installing it.
    2. Using a wooden block and hammer, tap in the spark plug tube to the specified protrusion height.

      NOTE:

      To avoid tapping in the spark plug tube too far, measure the protrusion height while tapping it.

  4. REPLACE RING PIN 
    NOTE:

    It is not necessary to remove the ring pin unless it is being replaced.

    1. Remove the ring pins.
    2. Using a plastic-faced hammer, tap in new ring pins to the cylinder head.
