Pic. 7.62. Removal of retaining and restrictive rings
To remove the overrunning clutch from the starter armature shaft, it is necessary to remove the retaining and restrictive rings (pic. 7.62).
Pull off (down to the pinion) stop ring from retaining ring. After that, the restrictive ring can be removed from the starter armature shaft.
Checking the absence of a short circuit in the armature winding «mass»
Pic. 7.63. Resistance check between each commutator lamella and armature core
Use an ohmmeter to check for a closed circuit (resistance) between each commutator lamella and armature core (pic. 7.63).
If the circuit is closed (resistance tends to zero), replace the starter armature assembly.
Checking the absence of a short circuit in the armature winding
Pic. 7.64. Checking the absence of a short circuit in the armature winding
Set the anchor in the growler (starter and alternator winding tester). If there are signs of a short circuit, replace the armature. If a thin steel plate located at the armature housing vibrates when the starter armature rotates, then the armature winding is short-circuited (pic. 7.64).
Checking the absence of a break in the armature winding
Pic. 7.65. Checking the absence of a break in the armature winding
Use an ohmmeter to check for a closed circuit (resistance) between collector lamellas (pic. 7.65).
If the circuit is open, then there is an open in the armature winding.
Checking the absence of a break in the stator winding
Pic. 7.66. Checking the absence of a break in the stator winding
Using an ohmmeter, check for a closed circuit between the brush terminals (pic. 7.66).
If the circuit is open, then there is an open in the stator winding. In this case, replace the starter housing assembly with the stator winding.

Pic. 7.67. Checking the absence of a short circuit in the stator winding «mass»
With the winding installed on the stator, check the absence of a closed circuit between the brush output (stator winding) and starter housing using an ohmmeter (pic. 7.67).
If the circuit is open, replace the starter housing assembly with the stator winding.
Brush check
Pic. 7.68. Brush wear line
Brushes worn below the limit line should be replaced (pic. 7.68).
Checking the brush holder
Pic. 7.69. Checking the absence of a closed circuit between the plate (a plus) brush holder and brush holder
Check for an open circuit between the plate (a plus) brush holder and brush holder (pic. 7.69).
If the circuit is shorted, replace the brush holder assembly.
Overrunning clutch test
Check drive gear and flywheel ring gear (models with manual transmission) or torque converter (models with automatic transmission) for scoring or excessive wear.
Pic. 7.70. Overrunning clutch test
Rotate the pinion gear while holding the freewheel housing. The gear should rotate smoothly, without binding, in one direction, and not rotate in the opposite direction (pic. 7.70).
Brush replacement
Remove the worn brush, being careful not to damage the brush wire.
Sand the end of the brush wire with sandpaper to ensure a strong solder.
Pic. 7.71. Place the solder end of the brush wire
Solder the end of the brush wire (pic. 7.71).
Rear Bracket Bushing Replacement
Before removing the bushing, measure and record the seating depth of the bushing in the bracket.
Pic. 7.72. Removing the sleeve
The sleeve can be removed with a puller, as shown in Figure 7.72.
Press in a new bushing so that its seating depth corresponds to the previously recorded value.
Assembly
Install a freewheel onto the forward end of the starter armature shaft.
Pic. 7.73. Installing the restrictor ring
Install the stop ring first, then the retaining ring on the front end of the starter armature shaft. Slide the freewheel stop ring onto the circlip until it stops (pic. 7.73).
Pic. 7.74. Lever location
When installing the lever in the front starter bracket, pay attention to the location of the lever. If the lever is set incorrectly (those. in the opposite direction), then the pinion gear remains in the extended position, and will not be able to work correctly (pic. 7.74).
Checking the starter relay
Pic. 7.75. Starter relay test circuit
Remove the starter relay and check the condition of the circuit between the terminals in accordance with the table. If the circuit condition is not as specified, replace the relay (pic. 7.75).
Checking the clutch pedal switch
Pic. 7.76. Clutch pedal switch test circuit
Check the condition of the circuit between the terminals in accordance with the table (pic. 7.76).
