How to remove the starter of a VAZ 2114 8 valve injector without pit

A starter is a necessary element of a car, designed to start the engine from the ignition key. The rotation of the starter is transmitted to the crankshaft through the flywheel.

The starter is a direct current electric motor, which includes: a stator (a stationary part consisting of windings); armature (shaft in the grooves of which the collector and winding are located); overrunning clutch (gear with a mechanical device) and retractor relay.

Reasons for removing the starter

It is worth noting the main malfunctions of the starter, which will require its removal.

The main problems with the starter that will require its removal are:

1. When you try to turn on the starter, the traction relay does not work, and accordingly the armature does not rotate.
2. When you try to turn on the starter, the traction relay is activated, but the starter does not turn or turns only slowly.
3. When you try to turn on the starter, the traction relay is activated and switched off several times.
4. When the starter is turned on, the armature rotates, but the engine flywheel does not.
5. When the armature rotates, the starter makes extraneous noise.

It is also worth noting, and will save your energy and nerves, that before removing the starter, make sure that the problem does not lie in a dead battery, oxidized terminals, broken electrical circuit, oxidized contacts, etc. To do this, familiarize yourself with the problems that affect the operation of the starter:

Malfunctions

During the operation of the vehicle, the following malfunctions of the starter are possible, which may lead to its replacement:

• overrunning clutch is faulty;
• short circuit of the stator or armature windings;
• significant wear of the brushes.

These malfunctions are characterized by the following symptoms:

• the starter armature rotates slowly;
• Uncharacteristic noises are heard when starting the engine.

If you ignore the slow rotation of the armature, of course, you won’t run into expensive repairs in the future, but you can run into trouble like this. But in case of noise, there is no need to postpone repairs.

It is quite possible, for example, that a malfunction may occur such as breaking out the teeth of the gear of the overrunning clutch mechanism, and here you can already run into an expensive replacement of the flywheel. However, before buying a new starter, you need to make sure that it is not possible to repair it!

Price

Prices for starters for VAZ 2114 in online stores are in the range of 2784...4520 rubles, and the cost of replacing it averages 500 rubles.

How to properly remove the starter?

1. We put the car in the pit and remove the engine protection by unscrewing the four fasteners.
2. Open the hood and remove the negative terminal from the battery.
3. Disconnect the wire block from the starter.
4. Remove the crankcase protection as shown in the figure.
5. Unscrew the fastening nut and remove the wire from the contact bolt of the starter traction relay.
6. We climb under the car and unscrew the 2 starter fasteners from below as shown in the figure.
7. We go up to the top and unscrew the last, third fastening of the starter.
8. Then we climb back into the hole and remove the starter.

What causes the starter to fail?

Understanding the reasons for the failure of a part, we can say that there are not so many of them:

• Manufacturing defects. Due to the design features of the body, the manufacturer had to reduce the size of the mechanism, so it has insufficient power and often fails;
• Operation of the device with unacceptable overloads. If you have to turn the engine for a long time, the element can overheat;
• Violation of operating rules. For example, a car enthusiast has run out of gas, and in order to move the car to the side of the road, he puts the car in gear and turns the starter, which allows him to move the car. The mechanism is not designed for such a load;
• Natural wear and tear of parts.

The mechanism is a defect of the manufacturer and is considered a “sore” of the VAZ 2114 car, as it often fails.

Useful video

You can get additional useful information on this issue from the video below:

Published August 03, 2019

On VAZ 2114/2115 cars, starters 29.3708 or 5712.3708 can be installed. Both starters are an electromechanical DC motor with mixed excitation and an electromagnetic two-winding traction relay. The main purpose, which is to create primary torque and transmit it through the flywheel to the crankshaft with the required speed.

The installation dimensions of the starters are the same - the differences are in the design of the commutator unit and the drive. The starter 29.3708 has a face-type commutator, the starter 5712.3708 has a cylindrical one, and the starter 5712.3708 also has a planetary gearbox in the drive.

When the starter stops working or works intermittently, starting the engine is very problematic and sometimes impossible.

Symptoms of a VAZ 2114 starter malfunction

Understanding the symptoms of a malfunction, we can highlight several points:

• When turning the ignition key, the mechanism does not move;
• Having started the engine, the bendix does not disengage from the flywheel;
• When you turn the ignition key, only electrical clicks are heard;
• The starter smokes when trying to start the engine;
• The mechanism hums, but does not engage the flywheel.

All the reasons are similar in one thing: the engine does not start rotating during a startup attempt. To determine exactly what the problem is, you will need to remove the mechanism and carry out diagnostics. There are several main reasons for failure:

• It doesn’t turn at all: when the winding is shorted, or the armature shaft on the solenoid relay is stuck;
• Insufficient speed: the armature or stator winding has broken or shorted, or the brushes have worn out;
• Does not transmit speed to the crankshaft: the bendix is ​​faulty;
• Does not turn off even after starting: the spring on the clutch is broken or the traction relay is stuck.

The principle of the device and its operation

Structurally, the starter 2114 is an electric motor powered by 12 volt direct current (on-board power supply). When the key is turned, its rotor begins to move, after which, with the help of a retractor relay, which brings the Bendix starter into engagement with the crankshaft flywheel, the latter begins to unwind.

After the combustion of the working mixture is initiated during rotation of the crankshaft and the engine starts, the retractor relay will move the bendix to the rear position and the starter will disengage with the flywheel.

Due to the fact that the starter has a fairly high load, its rated power is 1.55 kW.

In this case, the current strength in its circuit can reach:

• 80 A at idle;
• 375 A at maximum load;
• 700 A when in a braked state.

Starter design
As for the internal structure, the starter includes such components as:

• stator (fixed winding);
• rotor;
• bendix;
• brushes and their holders;
• solenoid relay;
• frame.

Also, sliding bushings, of which there are 3, are used as supporting elements for the rotor shaft in the starter. Two of them - front and rear - are pressed inside the body of the device, and the third is located at the point of contact between the bendix and the rotor.

Which starter should you choose?

When choosing a new spare part, most car owners give preference to the geared version. Its advantages are that it is smaller in size, turns the engine faster even with a dead battery, and works better in winter.

Of the gearbox options, everyone prefers the following companies:

• KZATE — 3600 rubles
• Eldix — 4500 rubles
• PRAMO – 4400 rubles

Try not to save money when buying a new part. As mentioned earlier, the item from the factory is considered the weak link of the car. If you buy a cheap Chinese analogue, you can return to removing the starter on a VAZ 2114 at the most inopportune moment. Read the reviews in stores in your region, this will help you identify quality brands and not fall for a fake, which will also save time and money.

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.

The disadvantage of geared devices is that there may be problems with waterproofing, which cause short circuits and anchor breakages.

Starter KZATE

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.

Replacing the starter on a VAZ 2114

Before removing the starter, you need to clear the engine compartment by removing the air filter housing. This will give us more access to the element's location. How to remove the starter on a VAZ 2114 without a pit? Access to the bolts is also open through the engine compartment; the only thing you have to do is tinker a little with the bottom bolt. Afterwards you can start repairing:

1. Remove the positive terminal from the battery. This must be done so as not to short-circuit the wiring and remove the voltage from it.
2. Then disconnect the plug of the red wire that pulls in the relay.
3. We take the key for 13 and disconnect the second wire from the body.
4. Now you can start removing the part itself. We unscrew the three 13mm bolts that secure the part to the box.

The starter no longer holds anything and you can remove it from its seat and pull it out.

When installing a new part, try to tighten the bolts firmly, but do not overdo it so as not to bend the threads or studs.

Required Tools

In order to carry out repairs yourself and replace a faulty starter, you need the tools that are listed in the table below. Table - Tools required to replace the front strut

Replacing the solenoid relay

It is not always necessary to replace the starter; sometimes simply servicing it is enough.

You can replace the solenoid relay without removing it, but then you will have to work a little, as this is quite inconvenient.

You can learn how to replace the relay correctly from the video:

Following the instructions from the article, replacing the starter on a VAZ 2114 with an 8-valve engine will not be so difficult. The starter is one of the most complex mechanisms in a car because it consists of many parts that wear out and fail over time. Although the system is only concerned with starting the car, there are many processes going on inside the case that must work in time and pass enough current to start the engine. It is impossible to monitor the condition of the internal parts, the only thing is that if you notice that the starter turns weakly and sometimes does not work, it is better to immediately remove it and take it for repairs or fix it yourself. This will save money on the subsequent purchase of a completely new element.

Do-it-yourself disassembly and repair

When you remove the starter, you need to disassemble it, otherwise you cannot repair it. To do this you need to follow this algorithm:

1. Using a key set to “13”, unscrew the nut and release the solenoid relay from the wire.
2. Using a Phillips or flathead screwdriver, unscrew the bolts that secure the relay.
3. Use a screwdriver to unscrew the bolts from the back cover.
4. Using a flathead screwdriver, remove the retaining ring. It is located on the rotor, on its back.
5. Unscrew the two nuts from the studs with a “10” wrench.
6. Unscrew the bolts that secure the wires coming from the windings to the brush holder.
7. Remove the entire starter brush assembly of VAZ 2112, 2114, etc.
8. Using a drift, remove the pin that secures the Bendix fork.
9. Remove the rotor, now it and the stator are separate.
10. There is a retaining ring on the rotor; after removing it, you can replace the bendix.

VAZ 2114 starter device

A car starter is designed to start an internal combustion engine by driving the engine crankshaft. The movement from the starter to the crankshaft is transmitted through the flywheel.

The VAZ 2114 car began to be produced by the Tolyatti Automobile Plant in 2000; it adopted many components and parts from its predecessor - the VAZ 2108-09 series. Accordingly, the design of the VAZ 2114 mechanism is very similar to its predecessor from the “nine”. The parts have external design differences, but the parts themselves are completely interchangeable with each other.

The VAZ 2114 starter consists of the following main parts:

1. Stator, which is made in the form of windings located in the housing;
2. Rotor (or armature), moving part;
3. Bendix, transmits motion from the rotor to the engine flywheel;
4. Solenoid relay is a device that drives the rotor by turning the ignition key.

Catalog number and cost of analogues

Finding a branded VAZ 2114 starter is not always easy. At the same time, the quality of the original components is very poor, which is further complemented by a high level of defects among the products sold. Therefore, experienced car owners recommend purchasing analogues from third-party manufacturers. The best alternative options for the original VAZ 2114 starter are presented in the table below.

The main reasons for the failure of the VAZ 2114 starter

There are not many reasons why a starter may fail. It could be:

• Manufacturing defects;
• Operation of the device with unacceptable overloads;
• Violation of operating rules;
• Natural wear and tear of parts.

It should be noted that in pursuit of compactness of all parts of the engine compartment, the manufacturer slightly did not calculate the power of the starting mechanism. The starter often fails due to its low power, which is a design flaw, a “disease” of the VAZ 2114. Often the starting mechanism breaks down in cold weather, when the engine has to be turned for a long time to start. It can fail prematurely if it is not secured properly. Wear of the bushing in the gearbox, which supports the starter armature, also contributes to breakdown (the bushing is shown with an arrow in the picture below).

Another typical factory defect is that the solenoid relay stops working the first time after a certain time. The factory apparently saves lubricant. Often, when disassembling an almost new solenoid relay, you can observe a completely dry core and the housing in which the core moves.

Differences between starter and relay failure

In order not to confuse what exactly has failed - the starter or the solenoid relay, there is an excellent method for recognizing the “culprit”.

• Remove the starter, connect the negative terminal of the battery to ground;
• The design of the device has copper bolts and a tongue-shaped element;
• The positive wire from the battery is connected to this “tongue”;
• If there is contact, the solenoid relay clicks and starts working;
• If not, then you will have to go to the store for a new relay.

But there is one more very important point. Even if all the facts indicate that the starter or retractor relay is not working, another unit - the ignition switch - may still be the cause of ignition problems. Take the time to check its serviceability before buying new parts.

Signs of a faulty VAZ 2114 starter

• When you turn the ignition key, the engine does not start;
• When starting, the engine continues to spin, the bendix does not disengage from the flywheel. You can stop the movement only by removing any terminal from the battery;
• When you turn the ignition key, “dry” clicks occur and the engine does not turn over;
• When you try to start the engine, smoke comes out of the starter and smells like burnt wire windings;
• When starting the engine, the starter buzzes and does not engage the flywheel. The launch does not happen the first time.

How it works

The device works as follows:

• The battery supplies power to the starter coil;
• The coil acts on the armature due to the influence of the magnetic floor;
• The armature moves and compresses the return spring;
• This causes the bendix to mate with the splines located on the flywheel;
• When the contact elements close, the pull-in winding is deprived of power, and the armature is held inside the system due to the magnetic field;
• After closing the contacts and starting the engine, power stops going to the holder coil, and the armature returns to its place due to the action of the spring. As a result, the bendix disengages.

Tips that may be useful when replacing a starter

1. Before removing the starter, you need to make sure it is faulty. First of all, you need to check the reliability of the terminals on the battery. Oxidized terminals should be cleaned of deposits and re-secured. The reason for the failure may also be poor weight of the engine and the body. You should also check whether the solenoid relay wire has come loose from the connector and whether the positive terminal nut on the starter is tightly tightened;
2. When removing a part, you can disconnect the positive wire of the terminal last. In this version, it is more convenient to unscrew the nut of the positive wire. By pulling the starter closer to you, it will be easier to get to the desired nut;
3. You need to install the solenoid relay wire in place until it stops. The connector must be fixed, and in this case the wire will not fly off during movement due to shaking;
4. Do not forget to first remove the terminals from the battery and turn off the ignition - this will save you from additional problems.

That’s basically all that can be said about how to change the starter on a VAZ 2114.

Checking work

Sometimes, despite more than obvious signs of breakage or wear of the retractor, in reality everything turns out to be wrong. The car may behave similarly with some other malfunctions.

Therefore, in order to figure out whether the relay works or not, and also who is the real culprit for the violation of the functionality of the system, we will conduct several checks.

1. Check the starter. Turn the ignition key. The starter should begin to turn, and the relay should make a characteristic click. If the starter is not doing its job, replace it. Relyukha has nothing to do with it in this case.
2. Check the solenoid relay. To do this, there are two copper bolts on the back cover. Two contacts are attached to them. If the starter starts turning, then your relay has definitely failed and needs to be replaced. In this case, you should not remove the starter, which will allow you to get more accurate test results.
3. If you have removed the starter, the check is performed slightly differently : Connect the contact wire of the retractor relay to the positive terminal of the battery;
4. The second contact connects the starter ground and the battery charger;
5. When the contacts are placed on the relay terminals, the relay should turn on with a characteristic click;
6. If the operation is too slow, uncharacteristic, check the condition of the contacts. They often burn out or oxidize.
