Check of a condition and replacement of components of the generator
Dismantling
Typical design of the automobile generator of an alternating current
|
|
1. Remove the generator from the engine (see Has undressed Removal and generator installation) and lay it on a pure workbench.
2. Give nuts of fastening of a back cover, release a plug nut In, throw off from the plug a washer and изоляционную the plug, then uncover (address to an illustration above).
3. Turn out screws of fastening of a regulator of pressure and щеткодержателя.
4. Remove щеткодержатель and a regulator of pressure from a back end face of a frame. If dismantling was made for the purpose of regulator replacement, pass to performance of procedure of paragraph 8, establish the new block, collect the generator and establish it on the engine (the Section Check of a condition of system of a charge see). In below-mentioned paragraphs the description of procedure of replacement of brushes is resulted.
5. Measure size выступания by each of brushes if results of measurements leave for the bottom border of an admissible range (see Specifications), replace brushes in gathering with the holder.
|
|
On some models the soldering iron can be necessary for replacement of brushes. |
6. Check up smoothness of a course of brushes in directing holder.
7. Remove выпрямительную assemblage. Remove four rubber изоляционных inserts and a sealing plate.
8. By means of a marker or чертилки mark mutual adjusting position of forward and back casings of the generator.
9. Give a fixing nut and remove приводной a pulley with роторного a generator shaft.
10. Give four fixing nuts have undressed generating assemblage on two parts.
11. Remove a persistent washer and take a rotor from a forward part of assemblage. |

Check
|
|
|
|
1. Measure resistance between two sliding contact rings (address to an accompanying illustration), the rating value makes 2 – 4 Ohm. Make sure of absence of conductivity between each of contact rings and роторной assemblage. At negative results of check, and also in case of excessive deterioration of contact rings replace a rotor. |
2. Check up on breakage статорные generator windings, conductivity should take place between each pair face plugs of assemblage. If in any of measurements the ohmmeter gives out the infinite indication, replace статор. Check up windings on presence of signs of breakdown on weight (conductivity presence between the plug and a frame. Defective статор is subject to replacement.
3. Check up serviceability of a condition of positive and negative section of the rectifier.
|
|
a. It is necessary to begin with check of positive section, – assemblage should have conductivity only in one of directions, polarity change should lead to situation change on opposite (address to an accompanying illustration). It is necessary to check up each of assemblage plugs serially; |
|
|
b. Further pass to check of negative section, – operate in a similar manner (address to an accompanying illustration). |
|
|
Assemblage
|
|
1. Installation of components is made as it should be the return to an order of their dismantle. Pay attention an order of performance of procedures.
2. At landing щеткодержателя on a generator shaft it is necessary to wring out serially by means of a small screw-driver each of coal brushes.
3. Screw fastening screws щеткодержателя and a pressure regulator.
4. Track reliability of a tightening of three nuts of fastening of a back cover.
5. Collect клеммную assemblage and fix its components the nut.
6. Establish the generator on the engine (see Has undressed Removal and generator installation). |
