Стартер Проверка

Mount the starter in a vise between aluminum plates.

Perform a pull-in test.

1. Remove the nut, and then 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, inspect the magnet starter switch assembly. If the magnet starter switch assembly is not as specified, replace it.
   

Perform a holding test.

1. 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 extended.

   If the clutch pinion gear returns inward, inspect the magnet starter switch assembly. If the magnet starter switch assembly is not as specified, replace it.
   

Inspect the clutch pinion gear return.

1. Disconnect the negative (-) terminal lead from the starter body. Check that the clutch pinion gear returns inward.
   If the clutch pinion gear does not return inward, inspect the magnet starter switch assembly. If the magnet starter switch assembly is not as specified, replace it.
   

Perform an operation test without load.

1. Connect the field coil lead wire to terminal C.

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

   Specified current:

   120 A or less at 11.5 V
   

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

   УКАЗАНИЕ:

   Inspect the starter brush holder assembly, starter yoke assembly and starter armature assembly. If there is a malfunction, replace the part and perform this test again.

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 C - Terminal 50	Always	Below 1 Ω

   *1	Terminal C
   *2	Terminal 50

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

Inspect the holding coil.

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

   Standard Resistance:

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

   *1	Switch Body
   *2	Terminal 50

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

Using a vernier caliper, measure the brush length.

Standard brush length:

16.5 mm (0.650 in.)

Minimum brush length:

9.0 mm (0.354 in.)

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

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

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

Check the brush spring load.

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

   Standard spring load:

   27 to 32 N (2.7 to 3.3 kgf, 6.0 to 7.3 lbf)
   

   Minimum spring load:

   18 N (2 kgf, 4.0 lbf)

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

Inspect for an open circuit.

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

   Standard Resistance:

   Tester Connection	Condition	Specified Condition
   Lead wire - Brush	Always	Below 1 Ω

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

Inspect for a short circuit.

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

   Standard Resistance:

   Tester Connection	Condition	Specified Condition
   Starter yoke body - Brush	Always	10 kΩ or higher

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

Check the commutator for dirt and/or burns on the surface.
If the surface is dirty or burnt, correct it with sandpaper (No. 400) or a lathe. Replace the armature if necessary.

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
   Segment - Coil core	Always	10 kΩ or higher

   *1	Segment
   *2	Coil Core

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

Inspect the commutator circle runout.

1. Place the armature on V-blocks.
   

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

   Maximum circle runout:

   0.05 mm (0.00197 in.)
   

   If the runout is more than the maximum, correct it with sandpaper (No. 400) or replace the starter armature assembly.
   

Using a vernier caliper, measure the commutator diameter.

Standard diameter:

35.0 mm (1.38 in.)

Measure the undercut depth of the commutator.

Standard depth:

0.7 mm (0.0276 in.)

Minimum depth:

0.2 mm (0.00787 in.)

Inspect the bearings.

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

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