СТАРТЕР (для моделей мощностью 1,4 кВт) ПРОВЕРКА


  1. INSPECT STARTER ASSEMBLY

    CAUTION:

    As a large electric current passes through the cable during this inspection, a thick cable must be used. If not, the cable may became hot and cause injury.

    Note

    The following tests must each be performed within 3 to 5 seconds to prevent the coil from burning out.


    1. Mount the starter in a vise between aluminum plates.

    2. Perform a pull-in test.


      1. Remove the nut, then disconnect the lead wire from terminal C.

      2. A01DVY9E01

        Connect the battery to the magnet starter switch as shown in the illustration. Then check that the clutch pinion gear extends.

        If the clutch pinion gear does not move, inspect the magnet starter switch assembly. If the magnet starter switch assembly is not as specified, replace it.

    3. A01DYMOE01

      Perform a holding test.


      1. Disconnect the negative (-) terminal lead from terminal C with the condition specified in the pull-in test above being maintained. Check that the pinion gear remains out.

        If the clutch pinion gear returns inward, inspect the magnet starter switch assembly. If the magnet starter switch assembly is not as specified, replace it.

    4. A01E0YX

      Inspect the clutch pinion gear return.


      1. Disconnect the negative (-) terminal lead from the starter body. Check that the clutch pinion gear returns inward.

        If the clutch pinion gear does not return inward, inspect the magnet starter switch assembly. If the magnet starter switch assembly is not as specified, replace it.

    5. Perform an operation test without load.


      1. Connect the lead wire to terminal C.

        Torque:
        5.9 N*m  { 60 kgf*cm, 52 in.*lbf }
      2. A01DZHFE01

        Connect the battery and an ammeter to the starter as shown in the illustration.

      3. Check that the starter rotates smoothly and steadily while the pinion gear is extended. Then measure the current.

        Specified current
        90 A or less at 11.5 V

        If the result is not as specified, inspect the starter assembly.
