Starter Inspection

Perform a pull-in test.

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





2. Connect the battery to the magnet starter switch as shown in the illustration. Check that the clutch pinion gear extends.
   If the clutch pinion gear does not move, replace the magnet starter switch assembly.
   

Perform a hold-in test.

1. Maintain the battery connections of the pull-in test above, but disconnect the negative (-) lead from terminal C. Check that the pinion gear remains extended.
   If the clutch pinion gear returns inward, replace the magnet starter switch assembly.
   

Check the clutch pinion gear return.

1. Disconnect the negative (-) lead from the starter body. Check that the clutch pinion gear returns.
   If the clutch pinion gear does not return, replace the magnet starter switch assembly.
   

Perform a no-load performance test.

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

   Torque:

   10 N*m{102 kgf*cm, 7 ft.*lbf}

2. Clamp the starter in a vise.
   

   NOTICE:

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

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

   NOTICE:

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

4. Check that the starter operates smoothly and steadily while the pinion gear is moving out. 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.
   

Check the starter clutch.

1. 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 starter repair service starter kit.
   

Inspect the plunger.

1. Push in the plunger and check that it returns quickly to its original position.
   If necessary, replace the magnet starter switch assembly.
   

Inspect 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 magnet starter switch assembly.
   

Inspect the hold-in coil.

1. 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 magnet starter switch assembly.
   

Check the surface of the commutator for dirt and burns.
If the surface is dirty or burnt, correct it with sandpaper (No. 400) 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.
   

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
   Commutator - Armature coil core	Always	10 kΩ or higher

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

Using a vernier caliper, measure the commutator length.

Standard length:

3.1 to 3.8 mm (0.122 to 0.149 in.)

Maximum length:

3.8 mm (0.149 in.)

Using a vernier caliper, measure the brush length.

Standard length:

4.0 to 9.0 mm (0.158 to 0.354 in.)

Minimum length:

4.0 mm (0.158 in.)

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 - Negative (-) brush	Always	10 kΩ or higher

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