How to change the brush on the generator with your own hands - step by step instruction and recommendations

Generator brushes are one of the important elements that are necessary for the proper operation of any vehicle. Due to these components, current is redirected along the circuit. If the brushes do not function, the system will stop producing tension. The entire airborne circuit will not operate from the generator, but from the battery. As a result, many mechanisms will not function at full power, while discharging the battery. Before changing the brushes on the generator, you need to pick up new items for later installation.

There are the simplest elements that have low strength and reliability, because of which you have to make a replacement very often. For a longer period of service, brushes are often treated with a special solution. For aggregates in which the main work occurs at high speeds, graphite brushes are excellent, which are designed for such conditions.

Prophylaxis when replacing

To ensure that the regulator has served as long as possible, the seat of the brush holder must be well vented. It will not be unnecessary to clean the contacts. Also, in disassembled form, you should check the strength of the spring and polish the contact ring. After this procedure, it is necessary to replace the brushes.

Replacement procedure without removing the generator

So, how to change brushes on the VAZ-2108 generator? It is very easy to do this, since they are attached to the generator using a single bolt. It is first necessary to disconnect the power terminals from the battery.

For greater convenience, when disconnecting the wires, use pliers, otherwise you can simply pull the wire from the terminal clip. It is necessary to remove not only the regulator wire, but the entire harness, which is suitable for the starter and the generator. After disconnecting it is necessary to take out a single bolt and to dismantle the voltage regulator. Then replace worn brushes with new ones. Next, you need to install the brushes and regulator in place.

Removing the device and replacing the brushes

In other cases on some cars it is not possible to replace the brushes without dismantling the generator. Many will wonder how to change the generator's brushes by removing it. In this case, you need to use the jack and lift the front of the car. Further it is necessary to climb under the car and to dismantle fixing bolts of protection of the engine and a mudguard from the right forward party. After removing the protection and the panel of the mudguard, you need to find a generator and a nut that holds the bracket. When unscrewing it, care must be taken to ensure that the sealing washers are not lost. Then unscrew the nut of the tension bracket of the generator. After the belt is dismantled.

As soon as all the fixing nuts have been unscrewed, it is necessary to disconnect from the generator suitable wires to it and remove the device itself. On it, unscrew the fastening of the three strands using a wrench. The last wire is removed by disconnecting the plastic pad. Further from the contacts of the brushes the suitable wire is disconnected and the old brushes are removed. Then new ones are installed. Assembly takes place in the reverse order.

After the brushes are replaced, you need to install the generator and check its performance with a voltmeter. Diagnosis of the operation of brushes is made through a simple visual inspection. For this, without removing the generator, it is necessary to remove the voltage regulator from it. If the projection of the brushes is less than 5 mm, they should be replaced. Remember that this operation is performed on the muffled engine and when removing the battery terminals.

When the generator brushes are replaced

Checking the brushes should be done every time you reach the mileage of about 50 000 km. By the way, their diagnosis is not a process that is included in the regular maintenance of the car. The state of the generator brushes should be checked every six months, and then the problem will not catch you unawares. It is worth remembering that in some cases, replacing the generator brushes can be carried out without removing the unit from the engine of the car. But sometimes you have to change the brush, taking off the generator. This makes the replacement more accessible and convenient.

To be fully confident in the failure of brushes, you should pay attention to the symptoms of auto:

• Sudden shutdown of some electronic devices.
• Reducing the brightness of the main headlights.
• Lowering in the on-board voltage circuit.
• Fast discharge of battery.

Each of these characteristics directly indicates the failure of the generator brushes.

Replacement of brushes on VAZ-2106

If the car owner thinks about how to change brushes on the VAZ-2106 generator, you need to know that these elements are installed on this car together with the brush holder. You can replace them without removing the device from the car. Some for more convenience, dismantle it and change the elements already on the device removed.

To replace the brushes, remove the wire terminal from the generator output. Then use a Phillips screwdriver to remove the screw securing the brush holder. Brushes from it should protrude at least 5 mm. If it is not, the holder is replaced. Remove the dust from the generator cover. Then in the reverse order it is necessary to install the holder on the generator and put it in place.

Replacement of items on the "Prior"

If the owner of the car notices that the generator does not give the right charge, it is likely that the problem lies in worn out brushes. Not every car owner knows how to change the brush on the generator. "Priora" has some differences when replacing these elements. In order to replace the brushes, you must first remove the generator from the car. Further, armed with keys on 13 and 10, and also a flat screwdriver, it is necessary to remove the part from the machine:

• Remove the cover by slightly bending it with a screwdriver.
• Then you need to disable the wiring that matches the brushes.
• To remove the elements, you need to unscrew the bolts that are at the edges.
• In addition, unscrew the hidden bolt by 13.

After that you can safely replace the generator brushes. The remaining length, as on all other cars, should be at least 5 mm. Assemble in the reverse order. After the generator is installed, it is necessary to check the generated charge.
