7.3.8. Dismantling, check of components and assembly of a starter

Fig. 7.62. Removal of lock and restrictive rings


For removal of the obgonny coupling from a shaft of an anchor of a starter it is necessary to remove lock and restrictive rings (fig. 7.62).
Pull together (down to the leading gear wheel) a restrictive ring from a lock ring. After that the restrictive ring can be removed from a starter anchor shaft.

Check of lack of short circuit of a winding of an anchor on "weight"

Fig. 7.63. Check of resistance between each lamel of a collector and the core of an anchor


By means of an ohmmeter check lack of the closed chain (resistance) between each lamel of a collector and the core of an anchor (fig. 7.63).
If the chain is closed (resistance tends to zero), replace a starter anchor assembled.

Check of lack of short circuit of a winding of an anchor

Fig. 7.64. Check of lack of short circuit of a winding of an anchor


Establish an anchor in a grauler (the device for check of a winding of a starter and the generator). If there are signs of short circuit, replace an anchor. If the thin steel plate located at the anchor case vibrates at rotation of an anchor of a starter, the winding of an anchor means it is closed накоротко (fig. 7.64).

Check of lack of break in an anchor winding

Fig. 7.65. Check of lack of break in an anchor winding


By means of an ohmmeter check existence of the closed chain (resistance) between lamels of a collector (fig. 7.65).
If the chain is opened, means there is a break at an anchor winding.

Check of lack of break in a stator winding

Fig. 7.66. Check of lack of break in a stator winding


By means of an ohmmeter check existence of the closed chain between conclusions of brushes (fig. 7.66).
If the chain is opened, means there is a break in a stator winding. In this case replace the starter case assembled with a stator winding.

Check of lack of short circuit of a winding of the stator on "weight"

Fig. 7.67. Check of lack of short circuit of a winding of the stator on "weight"


At the winding installed on the stator check lack of the closed chain between a brush conclusion (a stator winding) and the starter case, using an ohmmeter (fig. 7.67).
If the chain is closed, replace the starter case assembled with a stator winding.

Check of a brush

Fig. 7.68. Line of admissible wear of brushes


The brushes which are worn out below the maximum permissible line should be replaced (fig. 7.68).

Check of the brush holder

Fig. 7.69. Check of lack of the closed chain between a plate (plus) of the brush holder and the brush holder


Check lack of the closed chain between a plate (plus) of the brush holder and the brush holder (fig. 7.69).
If the chain is closed, replace the brush holder assembled.

Check of the obgonny coupling
Check the leading gear wheel and a gear wreath of a flywheel (model with MKPP) or the hydrotransformer (model with the automatic transmission) for lack of zadir or the increased wear.

Fig. 7.70. Check of the obgonny coupling


Rotate the leading gear wheel, holding the case of the obgonny coupling. The gear wheel has to rotate smoothly, without jammings in one direction and not rotate in an opposite direction (fig. 7.70).

Replacement of brushes
Remove a worn-out brush, trying not to damage a brush wire.
Smooth out an emery paper the end of a wire of a brush for providing the strong soldering.

Fig. 7.71. Place of solder of the end of a wire of a brush


Solder the end of a wire of a brush (fig. 7.71).

Replacement of the plug of a back arm
Before removal of the plug measure and write down depth of landing of the plug in an arm.

Fig. 7.72. Removal of the plug


The plug can be removed by means of a stripper, as shown in the figure 7.72.
Press the new plug so that depth of its landing corresponded to the value which is written down earlier.

Assembly
Install the obgonny coupling on the forward end of a shaft of an anchor of a starter.

Fig. 7.73. Installation of a restrictive ring


Establish at first a restrictive ring, then a lock ring on the forward end of a shaft of an anchor of a starter. Put on a restrictive ring of the obgonny coupling a lock ring against the stop (fig. 7.73).

Fig. 7.74. Lever arrangement


At installation of the lever in a forward arm of a starter pay attention to a lever arrangement. If the lever is installed incorrectly (i.e. in an opposite direction), then the leading gear wheel remains in the put-forward situation, and will not be able correctly to work (fig. 7.74).

Check of the relay of a starter

Fig. 7.75. Scheme of check of the relay of a starter


Remove the relay of a starter and check a condition of a chain between conclusions according to the table. If the condition of a chain differs from specified, then replace the relay (fig. 7.75).

Check of the sensor switch of a pedal of coupling

Fig. 7.76. Scheme of check of the sensor switch of a pedal of coupling


Check a condition of a chain between conclusions according to the table (fig. 7.76).
