Alternator belt tension on VAZ-2114

Important! When assembling the structure after replacing the generator, do not forget to adjust the tension of the drive belt.

As you can see, checking, selecting and replacing the generator on a VAZ-2114 is simple. All you need is desire and some automotive repair skills. It is worth noting that something as radical as replacement is not always necessary. Sometimes it is enough to take the generator set to an electrician, who can repair the part by replacing and cleaning its individual components.

Installation of the generator with subsequent adjustment

When installing a generator on a VAZ 2109 (no matter the injector or carburetor) and other models, be sure to check whether the purchased clamps, bolts and nuts fit the installation locations. Also, we must not forget that the mounting holes on old-style electric generators are different from new ones. Therefore, when installing a modern autogenerator on front-wheel drive models of the first generations (08, 09, 99), you should purchase the appropriate fasteners.

The generator mounting mount cannot be taken from Grants or Prioras. You can take a new potassium generator and no additional modifications will be required, but the mounting plates must be type 21082. In addition, you will need to purchase a pulley 2110 and a tensioner type 21082.

The installation process is identical to the removal process. If the standard strips are worn out, they are replaced with new ones; this will require unscrewing several bolts and installing new strips.

When installing the electric generator, start from the bottom fastening plate, tighten (but not completely) the fixing bolt (do not forget to put the bushing), put the belt on the pulley and move to the top. To fix the generator, install the top fastening, but do not screw it all the way. Then the tension bar is inserted. Then tighten the tension bolt, checking the belt tension.

The belt should not bend more than 1-1.5 cm when pressed with a force of 10 kgf. It is quite difficult to maintain these indicators in garage conditions, so you should focus on the gap between the frame and the tension bolt of 15–20 mm. There should be a small gap (15–20 mm) between the tension frame and the screw (from the thread side). Then turn the engine crankshaft two turns with a wrench and monitor the position of the belt and its tension.

If, after checking the engine by turning the key, the gap changes, then the bolts securing the electric generator should be tightened. As soon as, after a control rotation of the crankshaft with a key, the gap remains the same, and the belt bends slightly when you press it, the bolts of the upper and lower fastenings are finally tightened, a control rotation of the crankshaft is performed two turns, the wires are connected to the electric generator and the engine is started.

If, when starting the engine, the belt does not make unwanted noise or whistle, and the charge level is normal, then the installation procedure was completed correctly. If a whistle appears, then most likely the belt is too tight and should be loosened.

How to replace the generator on a VAZ 2113-VAZ 2115?

Note! We recommend that you replace the generator with exactly the same one (Similar), it just happens when people buy other generators and problems of this kind arise with them, for example, the generator is not suitable for this car and they cannot fix it (Mounts are in the wrong places), or it takes up there is too much space and cannot fit into the place where the original one stood before, so before removing the generator, take a look at its markings (it’s written right on it) and according to these markings and buy a new generator!

Removal: 1) You need to remove the generator through the bottom since it is convenient and there will be no difficulties in removing it, but for this the crankcase protection will need to be removed, otherwise it will interfere with removal (For information on how to remove the protection, read the article: “Replacing the protection crankcase on the car"), as soon as the protection is removed, be sure to remove the minus terminal from the battery, because if this is not done, then when you touch the wrench with the nut securing the plus terminal of the generator, a short circuit will occur and it will continue until until you remove the wrench from the nut (For information on how to remove the terminal, see the article: “Replacing the battery on a VAZ”).

2) Now move the rubber boot to the side with your hand (This is shown in both photos below) and under it you will find a nut that secures the plus terminals to the generator (The nut is indicated by a blue arrow), you unscrew this nut and then remove both terminals as soon as the terminals will be removed, disconnect the wire block (Indicated by the red arrow) by pulling it with your hand with a little force and thereby disconnecting it.

3) Next, using a wrench or a socket wrench, completely unscrew the adjusting bolt, which for clarity is indicated in the photo below with an arrow. By the way, there is a washer under this bolt, so remove it from the bolt when you take it out.

4) Then unscrew the nut of the upper bolt that the generator itself holds on the bar (Indicated by the red arrow), after which remove the nut from the bolt and remove the bolt itself from the generator, while also removing the tension bar (Indicated by the blue arrow) which is located behind the bolt.

5) Well, finally, unscrew the nut of the lower generator mounting bolt (see photo 1) and immediately behind this nut the spacer bushing will be located, you will also remove it, as soon as it is removed, take something heavy (Hammer for example) and knock the bolt out of the generator, with one hand while holding the generator itself suspended (see photo 2), just if you don’t do this, then when the bolt is removed, the generator will fall to the ground (By the way, you need to hit with a hammer not with the metal part, but the handle is made of wood, there is simply a high probability of damaging the bolt if you knock with the metal part).

Note! As soon as you slightly loosen the nut of the lower bolt, remove the belt from the generator (Indicated by the red arrow), to do this, move the generator closer to the engine with one hand, and with the other hand, remove the belt from the generator roller (Roller indicated by the blue arrow) and let it just hang there, not preventing the generator from being removed at the same time!

Installation: The new generator is installed in its place in the same way as it was removed, just the whole procedure occurs in the reverse order of removal, by the way, after installing the generator, put a belt on its roller and adjust its tension, for more details on how to do this, read the article : “Replacing the alternator belt on a VAZ.”

Additional video: Using the example of a VAZ 2110 car, see how the generator needs to be removed, the whole procedure for removing the generator on front-wheel drive cars is almost the same, but this no longer applies to new cars such as Lada Priora, etc. , because on them the generator is removed a little differently.

21.09.2020

A generator is an important element in the design of any car. The unit converts mechanical energy into electrical current, providing resources to all machine systems. A generator breakdown is a serious problem that you won’t be able to drive for a long time; the battery will be discharged almost immediately. You can deal with the trouble if you know how to replace a VAZ-2114 generator and other AvtoVAZ cars.

Repair

So, you have decided to purchase new bearings and follow a difficult but fairly economical path. For cars like the VAZ 2114, self-repair is a common thing. Such work, even in the absence of impressive experience and knowledge, is not difficult to do. Simple follow the instructions.

1. Disconnect the generator from the battery to deprive it of power.
2. Remove the timing belt.
3. Using wrenches of the appropriate size, remove the fastening nuts.
4. The film is removed, after which the sleeve is removed.
5. The generator itself is carefully removed from its seat.

This is interesting: Replacing the gasket under the valve cover on a VAZ 2101-2107

Subsequent work is more subtle and complex. After all, you have to disassemble the generator in order to get to the bearings. The task is not an easy one, but you can handle it yourself.

• There are nuts on the generator housing that need to be unscrewed;
• Remove the cover and remove the regulator from under it. This element is responsible for brushes and tension;
• Disconnect the stator from the cover. This operation should be done as carefully as possible so as not to damage the copper winding;
• Sometimes the housing can become rusty, making the stator difficult or even impossible to remove. In such a situation, arm yourself with a hammer and an impact screwdriver. With the help of these tools it is necessary to deliver the most accurate blows. This way you will be able to divide the element into blocks;
• Separating the generator from the stator, you will see both bearings - front and rear;
• Remove the damaged component and install a new alternator bearing in its place. Don't forget that there are two of them. For prevention, you can replace both at once, even if one of them is in completely good condition;
• Assembly is performed strictly in reverse order.

Working as a puller

Important Tips

There are several questions that you should know the answers to before you begin the job of replacing alternator bearings.

1. Installation must be carried out using a special press. Theoretically, it is possible to install a new element in place of the damaged one with an ordinary hammer, applying directed blows to the bearing. But this way you can damage the new spare part, plus additional damage to neighboring elements.
2. Make sure the new element is firmly in place. Only after this proceed with installing the pulley and impeller.
3. When purchasing a part, ask the seller what kind of vehicle this particular bearing is designed for. These parts differ in size.
4. During the replacement process, be sure to check the tension of the timing belt. If the tension is not strong enough, voltage sag may occur.

If the above operations do not produce results, you should look for other potential problems with the generator.

Disassembled generator

Consequences of a malfunction

A faulty bearing, like any other failure associated with generator components, leads to its malfunction. It is impossible to predict the consequences of such a breakdown.

Let’s just say that both an inadequate and an excessive charge pose a potential threat.

1. If the alternator does not provide sufficient charge, the battery will quickly discharge, so you will not be able to start the car or go anywhere.
2. If a charge is too powerful, the consequences are even sadder, since this puts the entire electrical circuit of your VAZ 2114 at risk.

Problems and solutions

There are several common generator problems that are more than possible to repair. Here you just need to follow certain recommendations and rules.

We invite you to familiarize yourself with the malfunctions and methods for solving them in the corresponding table.

Some motorists consider a number of car-related problems to be trivial and not worth paying much attention to. But they can sometimes lead to very serious, unpleasant consequences, the elimination of which will require not only a lot of effort and time, but also an impressive amount of money.

The generator and its components, including bearings, are complex elements that are quite difficult to repair or replace. If you do not have experience and skills in such matters, it is better to entrust the work to specialists.

How does the generator work on a VAZ?

Main details:

1. Brush holder with voltage regulator.
2. Stator.
3. Rotor.
4. Fan with pulley.
5. Distance ring.
6. Bushings.
7. Bearings.

How does the generator work on a VAZ?

With the help of the stator and the generating part, a 3-phase alternating current is generated, which 6 large diodes change to direct current, and the battery is charged.

The generator operates by rotating the crankshaft. The device is located under the hood, on VAZ cars - in the front part. Therefore, it is not difficult to remove the VAZ-2114 and other models generator.

Node diagnostics

When the generator set produces insufficient charge, the incoming voltage is not sufficient to power all electrical equipment. In this case, the battery comes to the rescue. As a result, it may completely discharge. Too high voltage is even more dangerous for the on-board network, as it can cause fuses to blow and electrical components to burn out.

Knowing what voltage the VAZ 2114 generator should produce, you can diagnose it to identify faults (the author of the video is Ildar Latypov).

Diagnostics is performed using a multimeter set to voltage measurement mode.

Checking the VAZ 2114 generator consists of a sequence of actions:

1. First you need to turn on the ignition and start the engine.
2. If there is damage in the rotor winding circuit, the warning light on the instrument panel will constantly light up.
3. The power unit should be warmed up to approximately 90 degrees. The crankshaft speed should be about 2500-3000 rpm.
4. Then you should turn on the low beam and radio.
5. Now you need to measure the voltage supplied to the battery terminals. It should be around 13 V.
6. Turning off the radio and turning off the low beams, we measure the voltage again. It should increase to 14.7 V.

During diagnostics, you should listen to the operation of the rotor. If the bearing in the front cover fails, noise will be heard.

A voltage drop is possible for the following reasons:

• weakening the tension of the generator belt;
• brush wear;
• malfunction of the relay regulator;
• wear and tear of the entire generating set.

If the generator unit is completely worn out, it must be completely replaced. Before replacing the generator on a VAZ 2114, you should diagnose it. If the battery is not charging, the reason may be a broken belt.

Types of mechanical failures

Failure in the technical part of the generator - wear of the bearings, bending of the pulley (if it is not bent too much, the device will work with a whistling belt), failure of the fasteners.

Attention! Mechanical breakdowns appear after an accident; they rarely occur during operation.

Signs of damage:

1. Unnatural noises when the generator is running.
2. Voltage drop.
3. The car drives faster, then slows down sharply when you press the gas pedal with the same amount of force.

Elimination of a simple breakdown - repair. If several parts fail on a VAZ-2113, 2114, 2115 or other Lada model, replacement is needed.

Types of electrical faults

The problem with the generator is that it stops producing current. The indicator on the dashboard lights up. Electrical faults lead to breakdown:

1. The fuse or contacts have blown. Making a replacement is a matter of minutes. With contacts things are different.
2. The brushes are worn out. You can change it yourself; you don’t need to buy a new device.
3. The regulator relay has failed. You can repair it yourself or contact a professional.
4. Diode bridge failure. Cannot be repaired, only replaced. To do this, you need to disassemble the generator; without experience, it is better not to carry out such work; it should be left to the experts.

Diode bridge failure.

1. An open circuit in the stator or rotor due to a short circuit. Repairing is more expensive than purchasing a new electrical unit.

Signs to help detect an electrical problem:

1. The battery indicator on the dashboard does not go out after starting the power unit or blinks.
2. Burnt wire smell coming from under the hood (a serious problem that may not be related to the alternator).
3. The appearance of sparks in the housing.
4. Voltage drop.
5. Constantly recharging the battery.
6. The headlights are adjusted, they shine dimly, and when other sources of power consumption are turned on, they almost do not light up.

How to remove a generator on a VAZ

On front-wheel drive Lada cars with an injector engine (with the exception of Vesta and Largus), the location of the device is the same. The fastenings are identical.

Removing the generator using the example of a VAZ-2115 with an 8-valve engine

Required tools:

1. Keys for 8, 10, 13, 17, 19.
2. Puller for convenience.
3. Adjustable wrench.
4. The head is 27 elongated.

Stages of work:

1. Remove the terminal (−) from the battery (must be done before starting any work).

Disconnecting the terminal from the battery

1. Unscrew the fastening bolt located below.
2. Move the terminal protective cover (on the side) and unscrew the fixing element.
3. Remove the top mounting bolt.
4. Remove the belt from the pulley.
5. Dismantle the device.

On a car with an 8-valve engine, you can do without a pit. The knot is taken from above. If the engine has 16 valves, it will be more difficult to remove.

On classic models (2101, 2105, 2106, 2107 and others), the generator is located under the hood; dismantling differs from front-wheel drive cars. The engine of the “classic” has a different location, which is why some peculiarities arise.

Removing the generator on a VAZ-2107

The same tool is needed. The process is as follows:

1. For convenience, drive the car onto the overpass.
2. Unscrew the terminal (−) from the battery.
3. Remove the battery (you will need a 10mm key).
4. Unscrew the top bolt with a 13 or 17 key (it differs on different models).
5. Remove the protection from the bottom.
6. Remove the belt.
7. Remove the wires from the device.
8. Bend the terminal protective cover (+) and unscrew it with a 10mm head.
9. Using a wrench (19), unscrew the nut securing the stator and the unit mount.
10. Remove the nut and remove the device from below.

After removal, you can begin repairing the generator. If key elements of the device fail, it is more economical to purchase a new one.

Procedure for replacing the generator

If the electrical unit fails and repair is impractical, you must first find a replacement. It is recommended to buy a factory version that will fit the fasteners and terminals. Otherwise, the repair will be accompanied by changing the wires.

Replacement process for VAZ 2109-2115:

1. Drive the car onto the overpass.
2. Remove engine protection.
3. Remove the (−) terminal from the battery.
4. Move the protective cover away from the positive one, unscrew the fixing bolt and remove the terminal.
5. Remove the wires (secured with a block).
6. Remove the upper fastening element.

Upper mounting bolt

1. Take off the belt.
2. Unscrew the bottom bolt.

Bottom bolt

1. Dismantle the device.
2. Install a new unit so that the fasteners match.
3. Secure with the lower and upper bolts.
4. Install the belt (preferably a new one).
5. Place the terminal, secure it, and return the protective cover.

Securing the terminals on the generator

1. Connect the wire block.
2. Adjust tension.

Attention! If you overtighten when adjusting the belt, the bearings will quickly fail. If the tension is weak, there will be no proper grip and the battery will not be able to charge.

To tighten, you need to turn the adjusting screw, which, when moving clockwise, is tightened, and when moved counterclockwise, it is loosened. It's easy to check - you need to gently press the belt so that it bends no more than 15 mm.

Features of the generator

The generator starts working immediately after starting the engine. Normally, the device produces a current in the range of 13.2 - 14.5 V. This current strength is enough to operate all the electronics in the car. If a powerful speaker system is installed in the car, then it is possible that the battery life will also be used. The voltage regulator, which is built into the generator, rectifies the current to the desired level and makes the system stable.

If the generator on a VAZ-2114 fails, the voltage drops below the stated parameters, and the car begins to use the battery. Since the part is quite expensive, and most often the cause of generator breakdown is faulty brushes, most often car enthusiasts resort to replacing them.

What you will need to remove the device

Since the generator is bolted on all sides, it is advisable to carry out all work in a garage with a pit. If there is no hole, then for convenience you can use a jack. The VAZ-2114 generator must be disconnected from all wires. To remove the part itself you will need:

• mount;
• keys at 10, 13, 15, 17, 19;
• knob with cap heads;
• rags.

It’s easier to unscrew hard-to-reach nuts with a wrench, but if you don’t have one, you can get by with wrenches. A rag will be needed to wipe the parts. Moisture often accumulates on the belt, and if you do not plan to replace it, it is better to immediately wipe the part with a rag.

How to troubleshoot the generator of the fourteenth VAZ model?

Troubleshooting depends on the reasons that caused them:

1. If the fuse is blown, it must be replaced. All fuses are located in the mounting block. A blown fuse indicates a fault in the circuit. It needs to be checked, the exact cause found and eliminated.
2. If there is no power, check that the negative wires are securely fastened.
3. If there are problems with the ignition switch, you need to check the contact group. If it is not possible to restore the lock's functionality, it should be completely replaced.
4. To identify problems that have arisen in the power circuit of the rotor winding, a control light is used. If it burns out, it needs to be replaced.
5. Replacing the generator brushes is carried out together with the voltage regulator relay. The regulator cannot be repaired separately.
6. The generator does not charge due to a broken drive belt; a new consumable is installed. In this case, the belt size must be appropriate so that the tension is sufficient. Replacing the VAZ 2114 8 valve and 16 valve alternator belt is similar.
7. If the on-board voltage is low due to weak belt tension, the tension needs to be adjusted.
8. If you hear a hum and crackling sound in the front cover of the generator, replace the bearing, since most often it is the cause of the noise.

How to properly dismantle a generator

Removing the device consists of only eight steps. If you follow the instructions, the part can be removed in just 10 - 15 minutes.

1. It is necessary to disconnect the negative terminal from the battery.
2. For convenience, it is better to remove the crankcase protection.
3. Next, you need to loosen the belt tension. To do this, loosen two bolts that are located on the side of the part.
4. After the belt has been loosened, the generator must be slightly moved towards the engine and the rubber part removed.
5. Due to the fact that the generator is completely removable, the belt tension bar can be removed.
6. The next step is to remove all terminals and pipes from the air conditioner.
7. After the generator is disconnected from all pipes, you need to unscrew all the bolts that secure it.
8. Since the part at the bottom is attached to a long bolt, which is difficult to unscrew, you can remove the generator along with the hardware, and then unscrew it.

Installation of a new generator occurs in the reverse order and requires care.

We also recommend reading our specialist’s article, which talks about how to remove the generator on a Priora.

It is not advisable to overtighten the fasteners, as this may lead to damage to the integrity of the part.

Unit Removal Guide

If the bearing is destroyed, disassembly of the generator is necessary, and for this you will have to dismantle it. The generator set is attached to the engine cylinder block on a special bracket. There is also a bar for adjusting the belt tension.

To remove the generator set on a VAZ 2114, you need to stock up on the following tools:

• a set of wrenches, preferably both box and open-end wrenches;
• socket head at “15”;
• mount, or a piece of metal pipe.

There are options for dismantling the generator set with or without removing the power unit protection. We will consider the option without dismantling the protection. Before removing the generator set, you must disconnect the negative terminal on the battery to avoid short circuiting.

The procedure consists of the following steps:

1. First, using a key set to “17”, you need to loosen the tension on the generator belt. To do this, you need to unscrew the fastening nut from above and move the unit to the cylinder block.
2. Next, you need to unscrew the nut on the output bolt “31” and disconnect the supply wire that goes to the rotor excitation winding.
3. The generator is attached to the bottom using a nut and a long bolt; they need to be unscrewed.
4. To make it more convenient to remove the generator, you need to unscrew the bar with which the unit is attached to the engine cylinder block. To do this, you need to unscrew two bolts.
5. You should also carefully unscrew the nut securing the bar to the starter. If the fasteners are stuck, you can use a penetrating lubricant, which makes it possible to remove rust and dirt.
6. To remove the axis of fastening the generator to the bracket, it is better to turn it clockwise.
7. Next, use a key set to “19” to unscrew the nut and remove it and the spacer sleeve.
8. Now the generator unit can be lifted up.

If you dismantle the generator through the bottom, you need to remove the protection.

Belt replacement

Replacing the VAZ-2114 alternator belt through the top consists of only seven steps:

1. The first stage involves disconnecting the terminal.
2. Next, you need to loosen the two generator mounting bolts to allow the belt to slack.
3. At the next stage, the generator must be moved towards the engine, and the belt, if possible, removed from the top.
4. When installing a new belt, you must first put it on the pulley and then on the roller. The pulley has larger dimensions, so it is quite easy to distinguish it from the roller (read more about how the generator belt tension roller works).
5. Next, you need to return the generator to its place and secure it.
6. When adjusting the tension, screw the adjusting bolt clockwise until the belt is in the desired position.
7. The last step is to tighten the bolts that hold the generator in place.

The belt is replaced on average every 30 thousand km, but if necessary, the part is changed much earlier. If the belt appears cracked or shows obvious signs of wear. Sometimes an unpleasant whistle when the engine is running reminds you of the need for replacement.

Bearing sizes and manufacturers

Before replacing a bearing with a new standard product, you need to buy it. The marking of these standard consumables is complex; the numbers in it are deciphered using special tables. Moreover, bearing designations according to GOST 3189 do not coincide with the markings of foreign manufacturers, so the user needs to know the following nuances:

• the marking consists of three parts (main, left, right), and blocks inside them;
• in the left and main parts the blocks are located from right to left, and in the right block on the contrary, from left to right;
• in cars, the front bearing of the generator most often has the designation of the main part 302 or 303, and the rear bearing 202 or 203;
• usually radial ball modifications with code 0 (0302 or 0202) or angular contact balls with code 6 (6303 and 6203) are used;
• therefore, for the specified parameters, you can decipher the dimensions using the table below;
• For foreign-made bearings, similar markings are used.

Marking of bearings according to GOST 3189

Table for deciphering bearing sizes by marking

Designation of imported bearings

The suffix (right side of the marking) of imported bearings contains additional information. For example, letters and numbers can represent:

• 2RS and RS – double-sided and single-sided rubber seals, respectively;
• N and NR – groove on the outer ring without a latch and with a latch, respectively;
• J – steel holder;
• Z – sheet protection on one side without seals.

The main problem for a car enthusiast when doing self-repair is the variety of bearing sizes inside the generator:

• it is difficult to guess the markings before disassembling, when the car is still running;
• after dismantling and disassembling the generator, the dimensions and markings are known to the owner, but he has to go to the store in a different car;
• in some stores, sellers practice a convenient system - the car owner takes 4 bearings 202, 203, 302 and 303, and returns two of them back.

These modifications have dimensions:

Replacing the brushes of the VAZ-2114 generator

If the generator does not cope with its tasks, then a complete replacement of the part is not always required. Sometimes all it takes is replacing the brushes, which will cost 10–15 times less than a new device. The easiest way to change brushes is when the generator is not removed. To do this, you need to disconnect the terminal and disconnect the wires going to the generator. The brush holder is removed, and the bolts securing it are first unscrewed. Old parts are removed, the seat is cleaned and new brushes are installed in it. On average, brushes are changed every 50 thousand km, but if the protruding part of the parts decreases by less than 5 mm, it is necessary to urgently replace the elements.
