The starter on the VAZ 2115 is used to start the internal combustion engine. It transmits the rotating motion to the crankshaft. If the unit is excessively worn or damaged, it becomes impossible or difficult to start the car.
Therefore, as soon as the first symptoms of a malfunction appear, attention to the unit is urgently required. It is necessary to diagnose the starter and, based on its results, make a decision on further repair or replacement of the unit.
Causes of malfunctions
- Does not turn: short circuit of the winding, jamming of the armature on the solenoid relay, oxidation of the battery contacts.
- Insufficient rotation speed of the bendix: break or short circuit of the armature (stator) winding, wear of the brushes.
- It turns, but does not transmit speed to the flywheel: the bendix is faulty.
- Operation after the engine speed has increased: the traction relay is stuck, the freewheel spring is broken.
Also, the causes of malfunction include wear of the unit, increased loads, violation of operating conditions and defects. Most often, the bendix, armature commutator and solenoid relay fail. Sometimes there is a loose fit of the brushes.
If one of the brushes has failed or the gearbox shaft has become skewed, this is usually a sign of impending destruction of the entire assembly, and it is easier to replace it entirely than to repair it.
In cold weather, the engine does not start well, the starter works at the limit and may fail. If the device is poorly secured or operates in conditions of constant strong vibrations, this also leads to its destruction. Sometimes a factory defect of the unit occurs - incorrect distribution of the lubricant composition in the housing, which leads to failure of the solenoid relay.
You can clean the shaft and add lubricant. The device is installed at an angle with the bendix down, white spirit is drawn into the syringe, and, turning the bendix as it extends, the white spirit is squeezed out onto the exposed section of the shaft, wiping it with a rag. Lubricant is added to the wedge-shaped teeth along which the bendix slides out.
For complete cleaning, the assembly is disassembled and washed in gasoline. Then they put new lubricant in the places from which the old one was removed, and assemble the device.
If the starter does not turn the flywheel, clean the terminals and start the car again.
Sometimes the problem with frequent bendix failure lies in the flywheel bushing. It is necessary to check the condition of the bushing and, if it is unsatisfactory, replace it with a new one.
Construction and something else
During operation, the internal combustion engine produces a fairly large amount of energy. It is enough for lighting devices, music, wipers, etc. In general, while driving, the main load goes to the generator. In a static position, the motor does not produce anything, so it needs to be started somehow. For this purpose, various types of starters are used along with batteries.
Most often, it is the starter solenoid relay that fails. Its price is fortunately affordable and starts from 500 rubles and ends in several thousand. In addition, the design includes a bendix with a drive gear and brushes.
Choosing a new starter
According to statistics, when answering the question “Which starter is better for a VAZ 2114?”, most car enthusiasts are advised to choose a geared version. It is smaller in size than the standard one, provides a quick start even with a weak battery, and spins the flywheel better in winter. It is easier and faster to install. The engine of such a device weighs less and experiences less mechanical stress.
Of the gearbox options, KZATE (KATEK) has the most positive reviews. Eldix and PRAMO brands are also popular.
Solution
- First you need to put your “nine” in neutral gear, and also turn on the parking brake.
- After this, the hood opens, you need to find the red cable on the retractor.
- Using a thick screwdriver, you need to short-circuit the terminals on this component. When a short circuit occurs, sparks may fly in different directions - there is no need to worry, this is a normal situation.
- Then you need to try to start the engine. If you notice that the starter starts to work normally when screwing in, then the problem is not with it. If the device does not turn, then most likely it will need to be changed.
- If the mechanism is working properly, the red wire from the solenoid relay must be removed, and voltage from the battery must be applied to this terminal. If there is a pop, the relay will be fully operational. If there was no clap, then most likely the reason lies precisely in the relay.
- Check the contacts on the starter, it happens that due to oxidation it stops turning.
Starter replacement
The work does not require a pit or a lift. When you don’t have time to travel to a car service center, you can replace the device yourself.
- Open the hood.
- Remove the terminals from the battery.
- Remove the air filter pipe.
- Remove the air filter.
- Find the starter between the radiator and the manual transmission.
- Unscrew the three nuts securing the device. To do this, use a key of 13.
- Remove wiring.
- Moving to the right and removing from the engine guides, remove the device.
- After dismantling, the condition of the flywheel shaft (bushing) is usually checked.
- The mechanism is installed in the reverse order.
When installing, apply lubricant to the surface in contact with the flywheel bushing.
Bendix replacement
- The plug at the point of its attachment to the body is bent with a flat screwdriver.
- The ring is removed. You may have to knock it down with a hammer.
- The retaining ring is removed. It is enough to pry it off with a flat screwdriver.
- The part is pulled out from the body.
If there is no visible damage on the bendix, this does not mean that it is working. If indirect signs of malfunction appear, it must be changed.
The new part is installed in the reverse order.

How to replace the Bendix VAZ 2109 correctly?
Bendix appearance:
Every owner of nines should know what a VAZ 2109 Bendix is and how to properly replace and diagnose it. So what is it and how to change it correctly? Bendix is a mechanism that is the connecting link between the starter rotor and the flywheel crown of the VAZ 2109 car. It contains a small number of elements - a gear and an overrunning clutch.
The first transmits rotational motion to the flywheel, and the second allows the gear to rotate in one direction. Note this property, it is very important for the normal functioning of the Bendix VAZ 2109 and other models.

Of the gearbox options, KZATE (KATEK) has the most positive reviews. Eldix and PRAMO brands are also popular.
The disadvantage of geared devices is that there may be problems with waterproofing, which cause short circuits and anchor breakages.
There are machines with the device fastened not with three, but with two bolts. In this case, a starter from ten is suitable, but you need to replace its Bendix with a gearbox from nine.
A starter with a gearbox: what is good and what are its disadvantages
We have already figured out how this device works and what its fundamental differences are. It is no longer difficult to guess which starter is better, gearbox or conventional. The fact is that the first option has the following strengths:
- small size and weight;
- long service life regardless of ambient temperature;
- low energy consumption (40% less than the classic version).
As for the disadvantages, they are there too and are as follows:
- complexity of repair work;
- lack of spare parts in stores;
- high cost of the product;
- low quality gearbox.
Often the main reason for the breakdown of a starter with a gearbox is that low-quality components are installed. This leads to breakdowns and various types of malfunctions. In general, such a unit has more prospects in the future than a conventional starter. And this is not due to the fact that one is good and the other is bad, but due to scientific and technological progress.

General information
The first starter used on a car had a number of significant shortcomings. Over time, the design was gradually improved and significantly transformed. The starter is a 4-band electric motor, which is necessary to rotate the crankshaft when starting the engine. It takes energy from the battery and increases the starting current several times. Due to this, any internal combustion engine starts. The principle of operation of the starter has not changed over the years.
Nevertheless, its design has been constantly improved. The weight of the part was reduced, the service life was increased due to the use of higher quality and new materials, etc. All this led to the fact that the starter was transformed quite significantly and even a new type appeared - gearbox. This is exactly what we will talk about now.
