STARTER(for Transaxle CVT with Stop and Start System) INSPECTION

PROCEDURE


  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 become hot and cause injury.

    Note

    Perform each of the following tests within 3 to 5 seconds to prevent the coil from burning out.


    1. Perform a pull-in test.


      1. A01LVXY

        Remove the nut, and disconnect the field coil lead wire from terminal M.

      2. A01M14BC02
        *a Terminal 50
        *b Terminal C
        *c Starter Body
        A01M03W Moves outward

        Connect a battery to the magnet starter switch assembly as shown in the illustration. Check that the clutch pinion gear moves outward.

        If the clutch pinion gear does not move outward, replace the magnet starter switch assembly.

    2. Perform a hold-in test.


      1. A01M3GDC02
        *a Terminal 50
        *b Terminal C
        *c Starter Body
        A01M03W Disconnect

        While maintaining the battery connections of the pull-in test, disconnect the negative (-) lead from terminal C. Check that the clutch pinion gear does not return inward.

        If the clutch pinion gear returns inward, replace the magnet starter switch assembly.

    3. Perform a return test.


      1. A01M1DNC02
        *a Terminal 50
        *b Starter Body
        A01M03W Disconnect
        A01LZQW Returns inward

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

        If the clutch pinion gear does not return inward, replace the magnet starter switch assembly.

    4. Perform a no-load performance test.


      1. A01LVXY

        Connect the field coil lead wire to terminal M with the nut. Make sure that the field coil lead wire is not grounded.

        Torque:
        9.0 N*m  { 92 kgf*cm, 80 in.*lbf }

      2. Secure the starter assembly in a vise between aluminum plates.

        Note

        Ensure that the starter assembly is secured in the vise to prevent it from falling out.

      3. A01M0PFC02
        *a Terminal 50
        *b Terminal 30
        *c Starter Body
        A01M03W Rotates

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

        Note

        Do not allow any lead to get caught as the clutch pinion gear operates.

      4. Check that the starter assembly operates smoothly and steadily while the clutch pinion gear is moving outward.

        Measure the current according to the value(s) in the table below.

        Standard Current

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

  2. INSPECT STARTER ARMATURE ASSEMBLY

    Tech Tips

    If there is no continuity between any segments, replace the starter armature assembly.

      *a Armature Shaft

      Check the commutator for runout.


      1. Place the armature shaft on V-blocks.

      2. Using a dial indicator, measure the runout.

        Maximum Runout
        0.05 mm (0.00197 in.)

        If the runout is greater than the maximum, replace the starter armature assembly.

    5. A01M1Y8
