STARTER(for 1.7 kW Type) 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 be hot and cause injury.

    Note

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


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

      Note

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

    2. Perform a pull-in test.


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

      2. A01HGX2C03
        *a Terminal 50
        *b Terminal C
        B0057RX Moves Outward

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

        If the clutch pinion gear does not move, replace the repair service starter kit.

    3. Perform a holding test.


      1. A01HI8HC03
        *a Terminal C
        B0057RX Disconnect

        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 moves inward, replace the repair service starter kit.

    4. A01HFY2C02
      B0057RX Disconnect
      B0059IK Returns Inward

      Check the clutch pinion gear return.


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

        If the clutch pinion gear does not move inward, replace the repair service starter kit.

    5. Perform a no-load performance test.


      1. Connect the lead wire to terminal C with the nut. Make sure that the lead wire is not grounded.

        Torque:
        10 N*m  { 102 kgf*cm, 7 ft.*lbf }
      2. A01HEW4C01
        *a Terminal 50
        *b Terminal 30
        *c AC/DC 400A Probe

        Connect the battery and an ammeter (AC/DC 400A probe) to the starter assembly as shown in the illustration.

        Note

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

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

        Standard current
        90 A or less at 11.5 V

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

  2. INSPECT REPAIR SERVICE STARTER KIT

    A01HINQ

    1. Check the plunger.


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

        If necessary, replace the repair service starter kit.

    2. A01HIFOC03
      *a Terminal 50
      *b Terminal C

      Check the pull-in coil.


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

        Standard Resistance
        Tester Connection Condition Specified Condition
        Terminal 50 - Terminal C Always Below 1 Ω

        If the result is not as specified, replace the repair service starter kit.

    3. Check the holding coil.


      1. A01HK2LC04
        *a Terminal 50
        *b Switch Body

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

        Standard Resistance
        Tester Connection Condition Specified Condition
        Terminal 50 - Switch body Always Below 2 Ω

        If the result is not as specified, replace the repair service starter kit.

  3. INSPECT STARTER COMMUTATOR END FRAME ASSEMBLY


    1. Check the brush length.


      1. A01HIWLC03
        *a Length

        Using a vernier caliper, measure the brush length.

        Standard length
        9.0 mm (0.354 in.)
        Minimum length
        4.0 mm (0.157 in.)

        If the length is less than the minimum, replace the starter commutator end frame assembly.

    2. Check the starter commutator end frame resistance.


      1. A01HJTS

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

        Standard Resistance
        Tester Connection Condition Specified Condition
        Positive (+) brush - Negative (-) brush Always 10 kΩ or higher

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

  4. INSPECT STARTER ARMATURE ASSEMBLY

    Tech Tips

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


    1. Check the commutator for contamination and burns on its surface.

      If the surface is dirty or burnt, correct it with sandpaper (No. 400) or a lathe.

    2. Check the commutator for an open circuit.


      1. A01HEAGC05
        *a Segment

        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.

    3. Check the commutator for a short circuit.


      1. A01HIATC05
        *a Segment
        *b Coil Core

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

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

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

    4. A01HIWZC04
      *a Length

      Using a vernier caliper, measure the commutator length.

      Standard length
      3.1 mm (0.122 in.)
      Maximum length
      3.8 mm (0.150 in.)

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

  5. INSPECT NO. 2 REPAIR SERVICE STARTER KIT


    1. Check the starter clutch.


      1. A01HJT7C03
        B0057RX Free
        B0059IK Lock

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

        If necessary, replace the No. 2 repair service starter kit.
