  2. CHECK V-RIBBED BELT FOR WEAR

    1. Check the V-ribbed belt for wear or damage.

      OK

      The V-ribbed belt is not worn or damaged.

    REPLACE OR ADJUST V-RIBBED BELT

  3. CHECK GENERATOR PULLEY WITH CLUTCH FOR WEAR

    1. Check the generator pulley with clutch grooves for wear or damage.

      OK

      The generator pulley with clutch grooves are not worn or damaged.

    REPLACE GENERATOR PULLEY WITH CLUTCH

  4. CHECK FOR NOISE WHILE CLUTCH PULLEY IS OPERATING

    1. Start the engine and check the generator pulley with clutch for looseness.

      OK

      The generator pulley with clutch is not loose.

    TIGHTEN GENERATOR PULLEY WITH CLUTCH TO SPECIFIED TORQUE

  5. INSPECT GENERATOR PULLEY WITH CLUTCH (UNIT INSPECTION)

    1. Remove the generator assembly (Click here).

    2. Check the installation condition of the generator pulley cap.

      OK

      The generator pulley cap is not loose or missing.

    3. Check for grease leaks (for wet pulley) or particle formation due to friction (for dry pulley).

      OK

      No grease leaks (for wet pulley) or large build-up of particles (for dry pulley).

    4. Check the generator pulley with clutch for misalignment (interference with the generator assembly).

      Using a screwdriver, hold the fan of the generator rotor assembly located inside the generator assembly in place and check that the generator pulley with clutch locks when turned clockwise and turns freely when turned counterclockwise.

      OK

      The generator pulley with clutch locks when turned clockwise and turns freely when turned counterclockwise.

    INSPECT PULLEY OTHER THAN GENERATOR ASSEMBLY PULLEY

    REPLACE GENERATOR PULLEY WITH CLUTCH

  6. CHECK FOR NOISE WHEN ROTOR IS TURNING FREELY

    1. Perform a road test and check that noise does not occur when decelerating.

      OK

      Noise does not occur.

    2. Turn the engine off and check that no noise is produced by the generator with clutch pulley as the engine stops.

      OK

      Noise does not occur.

    REPLACE GENERATOR PULLEY WITH CLUTCH

  7. CHECK ENGAGEMENT OF GENERATOR PULLEY WITH CLUTCH

    1. Remove the generator assembly (Click here).

    2. A288971
