  4. REMOVE NO. 1 ENGINE COVER SUB-ASSEMBLY


    1. A01G6L6

      Lift the rear of the No. 1 engine cover sub-assembly to detach it from the 2 pins.

    2. Lift the front of the No. 1 engine cover sub-assembly to detach the it from the pin and remove it.

      Note

      Attempting to disengage both front and rear pins at the same time may cause the No. 1 engine cover sub-assembly to break.

  5. REMOVE AIR CLEANER CAP SUB-ASSEMBLY


    1. A01G6TI

      Disconnect the vacuum switching valve assembly from the air cleaner cap sub-assembly.

    2. A01G9UT

      Disconnect the mass air flow meter connector and separate the 2 wire harness clamps from the air cleaner cap sub-assembly.

    3. A01G7KC

      Separate the fuel vapor feed hose from the air cleaner cap sub-assembly.

    4. A01G481

      Disconnect the ventilation hose from the cylinder head cover.

    5. A01G7ME

      Loosen the hose clamp and disconnect the air cleaner cap sub-assembly from the throttle with motor body assembly.

    6. A01G64N

      Release the 2 clamps and remove the air cleaner cap sub-assembly.

  6. DISCONNECT FUEL TUBE SUB-ASSEMBLY


    1. A01G6HQE01

      Remove the No. 1 fuel pipe clamp.

    2. A01G50PE01
      Text in Illustration
      *1 Fuel Pipe
      *2 Fuel Tube Connector
      *3 Nylon Tube
      *4 O-ring
      *5 Retainer
      A01G8AH Pinch
      A01G47H Pull

      Pinch the retainer of the fuel tube connector, and then pull the fuel tube connector off of the fuel pipe.

      Note


      • Check for foreign matter on the fuel tube around the fuel tube connector. Clean it if necessary. Foreign matter can affect the ability of the O-ring to seal the fuel tube connector and fuel pipe.

      • Do not use any tools to separate the fuel tube connector and fuel pipe.

      • Do not forcibly bend, kink or twist the nylon tube.

      • Keep the fuel tube connector and fuel pipe free from foreign matter.

      • If the fuel tube connector and fuel pipe are stuck, push and pull to release them.

      • Cover the fuel tube connector and fuel pipe with plastic bags to prevent damage and contamination.

    3. Disconnect the fuel tube sub-assembly from the fuel hose clamp.

  7. REMOVE VACUUM SWITCHING VALVE ASSEMBLY (for ACIS)


    1. A01G7OS
