STARTER (for 1.6 kW Type) INSPECTION


  1. INSPECT STARTER ARMATURE ASSEMBLY


    1. Check the commutator for dirt and/or burns on the surface.

      If the surface is dirty or burnt, correct it with 400-grit sandpaper or a lathe.

      Inspect the commutator for an open circuit.


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

        Standard Resistance
        Tester Connection Condition Specified Condition
        Segment - Segment Always Below 1 Ω

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

      *b Armature Coil Core

      Inspect the commutator for a short circuit.


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

        Standard Resistance
        Tester Connection Condition Specified Condition
        Segment - Armature coil core Always 10 kΩ or higher

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

    4. B007QOP

      Using a vernier caliper, measure the commutator diameter.

      Standard diameter
      29.0 mm (1.14 in.)
      Minimum diameter
      28.0 mm (1.10 in.)

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

    5. B007SXQ

      Check the commutator circle runout.


      1. Place the shaft of the starter armature on V-blocks.

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

        Maximum commutator runout
        0.05 mm (0.00197 in.)

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

    6. B007PP3

      Measure the undercut depth of the commutator.

      Standard undercut depth
      0.7 mm (0.0276 in.)
      Minimum undercut depth
      0.2 mm (0.00787 in.)

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

  2. INSPECT STARTER BRUSH HOLDER ASSEMBLY


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

      *a Brush *b Spring
      *c Length - -
      Standard length
      14.4 mm (0.567 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.

    2. B007U28E16

      *a Brush
      *b Brush Spring

      Inspect the load of the brush spring.


      1. Take a pull scale reading immediately after the brush spring separates from the brush.

        Standard spring load
        16 to 20 N (1.7 to 2.0 kgf, 3.6 to 4.5 lbf)
        Minimum spring load
        6.7 N (0.7 kgf, 1.5 lbf)

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

    3. B007TYRE01

      Inspect the insulation.


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

        Standard Resistance
        Tester Connection Condition Specified Condition
        Positive brush holder - Negative brush holder Always 10 kΩ or higher

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

  3. INSPECT STARTER CENTER BEARING CLUTCH SUB-ASSEMBLY


    1. Check the gear teeth of the planetary gears and starter center bearing clutch for wear or damage.

      If any planetary gear is damaged, replace the planetary gear assembly.

      If any gear of the starter center bearing clutch is damaged, replace the starter center bearing clutch sub-assembly.

    2. B007TF5

      Check the movement of the clutch pinion gear.

      B007QIC Lock

      1. Rotate the clutch pinion gear clockwise and check that it turns freely.

      2. Try to rotate the clutch pinion gear counterclockwise and check that it locks.

        If the clutch pinion gear cannot be turned clockwise smoothly, or does not lock in the counterclockwise direction, replace the starter center bearing clutch sub-assembly.

  4. INSPECT MAGNET STARTER SWITCH ASSEMBLY


    1. B007TPH

      Push in the plunger and check that it returns quickly to its original position.

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