Check of a state and replacement of components of the generator


Typical design of the automobile generator of alternating current

1 — the Pulley
2 — the Cover from the drive
3 — the Forward bearing
4 — the Holder
5 — the Rotor
6 — the Back bearing
7 — a bearing Cover
8 — the Rubber insulating insert

9 — Pruzhina
10 — the Brush
11 — tension Regulator
12 — the Cover from contact rings
13 — the Holder of vypryamitelny assembly
14 — the Terminal insulator
15 — the Brush holder with a cover
16 — the Back cover


1. Remove the generator from the engine (see the Section Removal and installation of the generator) and lay it on a pure workbench.
2. Give nuts of fastening of a back cover, release a plug B nut, throw off a washer and the insulating plug from the plug, then uncover (address an illustration above).
3. Turn out screws of fastening of the regulator of tension and the brush holder.
4. Remove the brush holder and the regulator of tension from a back end face of a frame. If dismantling was made for the purpose of replacement of the regulator, pass to implementation of the procedure of paragraph 8, install the new block, collect the generator and install it on the engine (see the Section Check of a Condition of System of a Charge). The description of the procedure of replacement of brushes is provided in the following paragraphs.
5. Measure the size of a vystupaniye of each of brushes if results of measurements go beyond the lower bound of admissible range (see Specifications), replace brushes assembled with the holder.

On some models the soldering iron can be necessary for replacement of brushes.

6. Check smoothness of the course of brushes in the holder's guides.
7. Remove vypryamitelny assembly. Remove four rubber insulating inserts and a sealing plate.
8. By means of a marker or a chertilka mark the mutual adjusting provision of forward and back casings of the generator.
9. Give a fixing nut and remove a driving pulley from a rotor shaft of the generator.
10. Give four fixing nuts divide generating assembly into two parts.
11. Remove a persistent washer and take a rotor from a forward part of assembly.



1. Measure resistance between two sliding contact rings (address an accompanying illustration), the nominal rate makes 2 – 4 Ohms. Make sure of lack of conductivity between each of contact rings and rotor assembly. At negative results of check, and also in case of excessive wear of contact rings replace a rotor.
2. Check statorny windings of the generator for break, conductivity has to take place between each pair of face plugs of assembly. If in any of measurements the ohmmeter issues the infinite indication, replace the stator. Check windings for existence of signs of breakdown on weight (existence of conductivity between the plug and a frame. The defective stator is subject to replacement.
3. Check serviceability of a condition of positive and negative section of the rectifier.   
   a. It is necessary to begin with check of positive section, – assembly has to have conductivity only in one of the directions, change of polarity has to lead to change of a situation on opposite (address an accompanying illustration). It is necessary to check each of assembly plugs serially;
   b. Further you pass to check of negative section, – act in a similar manner (address an accompanying illustration).



1. Installation of components is made as it should be the return to an order of their dismantle. Pay attention a performing procedures order.
2. When landing the brush holder to a shaft of the generator it is necessary to wring out serially by means of the small screw-driver each of coal brushes.
3. Screw screws of fastening of the brush holder and the regulator of tension.
4. Track reliability of tightening of three nuts of fastening of a back cover.
5. Collect terminal assembly and fix its components by the nut.
6. Install the generator on the engine (see the Section Removal and installation of the generator).
