STARTER (for 2.2 kW Type) INSPECTION


  1. INSPECT STARTER

    A01BI07E01

    Note

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


    1. Perform pull-in/holding test.


      1. Remove the nut and disconnect the field coil lead wire from terminal C.

      2. Connect the battery to the magnet starter switch assembly as shown in the illustration. Then check that the clutch pinion gear moves outward.

      3. Disconnect the negative (-) lead from terminal C. Check that the pinion gear remains out.

        A01BHQ1E01

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

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

    2. Perform operation test without load.


      1. Install the field coil lead wire with the nut to the terminal C.

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

      2. Mount the starter in a vise.

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

      1. Measure the resistance between any 2 segments of the commutator.

        Standard resistance
        Below 1 Ω

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

      2. A01BHQ4E02

        Measure the resistance between a segment of the commutator and armature coil core.

        Standard resistance
        10 kΩ or higher

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

    2. A01BDZU

      Inspect the commutator for circle runout.


      1. Place the armature on V-blocks.

      2. Using a dial gauge, measure the circle runout.

        Maximum circle runout
        0.05 mm (0.0020 in.)

        If the circle runout is greater than the maximum, correct with sandpaper (#400) or replace the starter armature assembly.

    3. A01BC53

      Using a vernier caliper, measure the commutator diameter.

      Standard commutator diameter
      35.0 mm (1.378 in.)
      Minimum commutator diameter
      34.0 mm (1.339 in.)

      If the diameter is less than the minimum, replace the starter armature assembly.

    4. A01BHZ3

      Using a vernier caliper, measure the undercut depth of the commutator.

      Standard undercut depth
      0.7 mm (0.028 in.)
      Minimum undercut depth
      0.2 mm (0.008 in.)

      If the undercut depth is less than the minimum, correct it with a hacksaw blade.

    5. Inspect the bearings.


      1. Check that the bearings rotate smoothly. If the result is not as specified, replace the starter armature assembly.

  3. INSPECT STARTER YOKE ASSEMBLY


    1. A01BDOVE02

      Inspect the field coil for open circuit.


      1. Measure the resistance between the lead wire and field coil brush lead.

        Standard resistance
        Below 1 Ω

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

    2. A01BB61E02

      Inspect the field coil for ground.


      1. Measure the resistance between the terminal C wire and starter yoke body.

      2. Measure the resistance between the brushes and starter yoke body.

        Standard resistance
        10 kΩ or higher

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

  4. INSPECT BRUSH

    A01BF6RE01

    1. Using a vernier caliper, measure the brush length.

      Standard length
      16.5 mm (0.650 in.)
      Minimum length
      9.0 mm (0.354 in.)

      If the length is less than the minimum, replace the starter brush holder assembly and starter yoke assembly.

  5. INSPECT STARTER BRUSH HOLDER ASSEMBLY


    1. A01BD5AE01

      Inspect the brush insulation.


      1. Using an ohmmeter, measure the resistance between the positive and negative brush holders.

        Standard resistance
        10 kΩ or higher

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

    2. A01BHRA

      Take the pull scale reading the instant the brush spring separates from the brush.

      Standard spring installed load
      26.5 to 32.3 N (2.7 to 3.3 kgf, 5.9 to 7.3 lbf)
      Minimum spring installed load
      17.6 N (1.8 kgf, 4.0 lbf)

      If the spring load is less than the minimum, replace the starter brush holder assembly.

  6. INSPECT STARTER CLUTCH SUB-ASSEMBLY


    1. A01BH3KE01

      Rotate the pinion gear clockwise, and check that it turns freely. Try to rotate the pinion gear counterclockwise and check that it locks.

      If necessary, replace the starter clutch subassembly.

  7. INSPECT MAGNET STARTER SWITCH ASSEMBLY
