7.3.8. Dismantling, check of components and starter assembly

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 a leading gear wheel) a restrictive ring from a lock ring. After that the restrictive ring can be removed from a shaft of an anchor of a starter.

Fig. 7.63. Resistance check between everyone ламелью a collector and the anchor core

By means of an ohmmeter check absence closed chains (resistance) between everyone ламелью a collector and the anchor core (fig. 7.63).

If the chain is closed (resistance aspires to zero), replace a starter anchor assembled.

Fig. 7.64. Check of absence 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 case of an anchor, vibrates at rotation of an anchor of a starter, the winding of an anchor means is closed накоротко (fig. 7.64).

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

By means of an ohmmeter check existence closed chains (resistance) between ламелями a collector (fig. 7.65).

If the chain is opened, means there is a break at an anchor winding.

Fig. 7.66. Check of absence 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.

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

At the winding established on a 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.

Fig. 7.68. Line of admissible wear of brushes

The brushes worn out below the maximum permissible line it is necessary to replace (fig. 7.68).

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

Check lack of the closed chain between a plate (plus) of a shchetkoderzhatel and a shchetkoderzhatel (fig. 7.69).

If the chain is closed, replace a shchetkoderzhatel assembled.

Check a leading gear wheel and a gear wreath of a flywheel (model with MKPP) or the hydrotransformer (model with AKPP) on absence задиров or the increased wear.

Fig. 7.70. Check of the obgonny coupling

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

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).

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

Fig. 7.72. Plug removal

The plug can be removed by means of a stripper, as is shown in drawing 7.72.

Press the new plug so that depth of its landing corresponded to the value written down earlier.

Establish the obgonny coupling for 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 for 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 lever installation in a forward arm of a starter pay attention to a lever arrangement. If the lever is established incorrectly (i.e. in an opposite direction), the leading gear wheel remains in the put-forward situation, and (fig. 7.74) cannot correctly work.

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

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

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

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