Generator Lada Priora price, article number, location, principle of operation

Without electricity, nothing will work. So on a car, the voltage in the on-board network is maintained by a generator. You need to understand how many amperes you need in the on-board network.

It all depends on the amount of attachments, air conditioning, heating, etc. Depending on the configuration, a generator is also selected. Read the article to the end and we will cover this topic. Removing and replacing the generator on a Lada Priora car depends on the attachments; if the car does not have air conditioning, then the unit can be removed in 6 steps. If the air conditioner costs 9 steps, we will talk about them in the article. This part on Priora comes in 3 types. Their prices are also different.

The generator tension roller 2170 serves to tension the belt. One of the important tips for beginners: if you unscrew any bolt when changing a part, lubricate it with graphite grease, this will greatly facilitate repairs in the future.

The principle of operation, what it consists of and the main malfunctions

The generator converts the mechanical energy coming from the engine into electrical energy. The principle of operation and its design are the same for all cars. The difference lies only in the quality, dimensions and location of the connecting nodes.

What it consists of:

Pulley - transmits mechanical energy through the belt from the engine to the generator.
The body is presented in the form of two covers. The starter is attached to them and the rotor supports are placed. The back cover contains external terminals for connecting to electrical equipment, a voltage regulator, a rectifier and a brush assembly.
Stator - produces power. It is made of steel sheets and has the shape of a pipe. A three-phase winding is installed in the stator slots.
The rotor is the moving part of the unit. When the engine starts, the rotor begins to rotate, and voltage is supplied to its exciting winding from the battery. The steel core becomes electromagnetic, creating an alternating magnetic field when rotated.
Voltage regulator - maintains voltage stability in the on-board network when the ambient temperature and rotor speed changes.
Assembly with rectifier diodes
Diode module cover
The brush assembly is a removable structure where brushes are installed that interact with the rotor rings.

Verification Guide

How much voltage does the VAZ 2110 generator device produce and how much voltage should it produce? What generator voltage should be in the on-board network to ensure normal operation of units and components? Many drivers have no idea how the device should be checked if there is low voltage in the network, but we are ready to share this information with you.

Tools and materials

To check the generator, you will need:

tester (multimeter);
control light with wire;
set of wrenches;
power supply with voltage regulator.

Algorithm of actions

Before increasing the voltage, it is necessary to correctly diagnose:

First, pay attention to the indicator light on the control panel. This light works as follows: it appears when the ignition is turned on, but disappears after the engine starts

If the indicator continues to light when the engine is running, this indicates that the battery is not charging. using a multimeter, diagnose the voltage in the car's electrical wiring; this parameter must be at least 12 volts. As practice shows, the reason for the appearance of the indicator is usually associated with either wiring faults in the on-board network or a break in the device’s strap. If the indicator lights up at half strength, then most likely the problem lies in weak strap tension. The problem can be solved by tensioning it to the desired state; this will allow increasing the voltage. The next step will be diagnosing fuse F2 - if the strap is tensioned correctly, the voltage level in the wiring should correspond to the nominal one. If the fuse is faulty, you need to replace it, then check for the presence of a charge on the battery itself. If the fuse is working or replacing it does not produce results, try measuring the parameter at pin 61 - the resulting value should be approximately 6 volts. If you detect a lack of voltage, you need to dismantle the control panel and look for the cause in the soldering areas. It often happens that the problem is a break in one or another cable that goes to the control panel from the 61 connector. The next stage of testing, if the measured parameter is higher than the nominal value, is to remove the regulator relay. Relay diagnostics are carried out using a test light; to do this, apply a 12-volt current to the relay. In this case, the plus is supplied to the plug output of the relay, and the minus is supplied to the vehicle body. The light bulb itself, rated for 12 volts, must be connected to the regulator brushes. If the voltage level is 12 volts, then the light bulb will light without problems, and when this parameter increases to 16 volts, the light bulb will go out. If the lamp does not go out, then it is necessary to replace the regulator relay. But if the relay is working properly, but there is no charging, then the only way out is to dismantle the generator and find the fault in it. Next, using a multimeter, you need to check the performance of the winding; the resistance level in this case should be 4.5 Ohms. If the resistance is lower, then the winding needs to be repaired, that is, change the armature or simply rewind the element. In some cases, the problem lies in clogged slip rings - this problem can be solved by replacing or cleaning them. If after these steps the tester still shows a break in the wiring in the winding, the rotor will need to be replaced. The next step will be to check the diode bridge of the VAZ generator; in particular, each diode should be diagnosed for breakdown. The semiconductor itself transmits current in one direction, and diode diagnostics are carried out accordingly. If several elements burn out at once and it is not possible to get rid of the malfunction, then the unit must be completely replaced with a new one.

Principle of operation

When you turn the ignition on, current from the battery enters the field winding through the brush assembly, where a magnetic field appears. When the crankshaft rotates, the rotor goes into rotation. The magnetic field passes through the stator winding and an alternating voltage is generated at the output. Having reached a certain rotation speed, the excitation winding begins to be powered directly from the generator.

The alternating voltage is changed to constant thanks to the rectifier unit. Now the generator charges the battery and powers consumers. When the rotation speed changes, the voltage regulator is connected to the operation.

Basic faults

Why does the generator not charge the Lada Priora car? There may be several reasons:

the diode bridge is damaged;
the turns of the stator winding are closed;
slip rings wear out;
the pulley is damaged or worn out;
the wires of the charging circuit are damaged;
the bearing is destroyed or worn out;
the voltage regulator is damaged;
The current collecting brushes wear out.

In all of the above cases, repair of the Lada Priora generator will be required.

Removing and installing the generator

For the owner of a vehicle manufactured by AvtoVAZ, which is equipped with air conditioning, the question of how to remove the generator from a Lada Priora car will be more difficult.

Tight installation of components and assemblies under the hood will complicate the procedure. Installation of a new unit is carried out in the reverse order of the removal procedure. After replacing, do not forget to tighten the timing belt.

How to remove a generator on a Priora with air conditioning:

Remove the protection on the engine.
We loosen the tension of the drive belt roller.
The upper mounting bolt can be easily unscrewed with a 13 mm socket wrench.
The bolts that hold the air conditioning compressor are unscrewed.
The Lada Priora alternator belt going to the compressor is being replaced.
The part should be moved slightly towards the battery. This will give you access to the bolt that secures the air conditioning compressor.
After unscrewing the last fastener, the compressor is hung. There is no need to fix it.
Now the bolts securing the part are unscrewed.
The terminals are disconnected and the alternator belt of a Lada Priora car with air conditioning is replaced.

Without air conditioning

Disconnect the terminals from the generator connectors.
Remove the drive belt. To do this, you need to loosen its tension.
Unscrew the generator bracket bolts. Top and then bottom. The bottom bolt is unscrewed from under the car.
We turn out the adjusting bolt.
Remove the bottom bar.
We remove the part.

Replacing the Priora generator 16 valves with your own hands video

VAZ car models usually do not present any difficulty with simple repairs or disassembly, they are inexpensive to service in almost any service center, and the basic configurations, if necessary, are suitable even for beginners. But if you need to replace a Priora 16 valve generator with air conditioning or power steering, dismantling it will be quite difficult due to the narrower space under the hood, and preparation is required.

Why, in fact, is it difficult to replace a generator on a Priora 16 valves?

The sixteen-valve version has a much narrower distance between the head and the radiator than the eight-valve version.

If you remove the mounting bolts on a 16-valve generator, it will still not be possible to remove it - it will rest against the radiator. Because the free space under the hood will be occupied by a compressor or pump.

Do not pull on the generator under any circumstances, this will damage the radiator. If something doesn't come off on its own, don't force it.

How to remove the generator

It is preferable to have a crane beam indoors; in extreme cases, you can use a jack on wheels, special for hanging the engine. You should proceed in the following way.

Disconnect the battery terminals.
Hang up the motor.
Remove the drive belt.
Loosen the hoses on the power steering or air conditioning.
Remove the mountings from the generator.
The generator can now be disconnected and powered up. First to the side, then up.
When all wiring is disconnected, the generator can be removed.

Replacing the alternator belt on a Priora 16 valve is carried out in the reverse order, just install the new part following the instructions.

How to remove a generator on a Lada without air conditioning

If you do not have additional equipment installed, replacing the Priora 16 valve generator will be a little easier, since there will be more space under the hood.

Remove the negative terminal from the battery.
Remove the protection from the engine.
Unscrew the nut on the belt tensioner (not completely, a maximum of four turns). Now you can turn it around by turning the screw a little. When it is loose enough, you can remove it.
Remove the protective cap to later remove the terminal from the wiring harness. Now you can remove the wiring block.
Remove the nut to remove the top mounting bolt, then do the same with the bottom mounting bolt.
Remove the belt and then the entire generator.

Since in advanced configurations with air conditioning the belt on the generator is longer, then if it is necessary to replace it, you need to remember some subtleties. Especially if you feel that the quality of grip on the rollers has become much worse, then you will have to re-tension or change them.

The first thing that indicates a problem is a whistle, a clear decrease in the battery charge level, even if it should be fully charged. New batteries can be ordered here: https://www.rimir.by/products/car/akkumulyatory-95/. In this case, first of all, you should look at the belt to see if it is elastic, if there are any third-party cracks on it.

Replacing the Priora 16 valve alternator belt should be done after 60 thousand kilometers, or once every two years.

How to change power steering

You will need an inspection hole and a wheel wrench.

Loosen the nut to remove the adjusting bolt.
Now you can move the generator away.
Removing the right front wheel and its wheel arch liner will reveal the space in front of the old belt.
From here it can be easily removed.
You can install a new one. The main thing is to tighten it correctly and well.

How to tension a belt and check its tension

For Priora, in addition to the original ones, similar belts from foreign brands such as Contitech, Dayco, Gates, and Flennor are recommended.

Loosen the roller nut; you will have to hold the cage with a wrench. By then rotating this key, the clip can be turned.
Tighten the nut against the roller. Check the quality of tension only on the long section between the pulleys. If, when pressing on the belt in this place, it bends no more than 10 millimeters, the tension is appropriate.
If your Lada has a hydraulic booster, you should tighten it a little more. If you don't pull it tight enough, it will whistle obviously, a defect that can be easily detected by ear. Then pull it a little tighter. If you hear not a whistle, but a hum, the belt, on the contrary, needs to be lowered.

On a Priora, in a regular service, changing just the belt can cost from 300 rubles (not counting consumables). If the generator is with rollers or mounted, then the price will increase significantly to one and a half thousand rubles.

Do not forget the receipt for the services provided; the warranty for the work performed must be at least six months; if the belt deteriorates due to poor installation or tension, you must demand a replacement at the expense of the service.

Alternator bearings for Lada Priora: diagnostics, signs of malfunction and replacement

The following circumstances indicate the need to replace the bearing:

Malfunctions of electrical equipment;

Extraneous noises, whistling and humming when starting up;

Slow or insufficient battery charging;

Distinct beating due to uneven rotation of the shaft;

Diagnosis of the malfunction is carried out using the following steps:

We remove the belt.
We start the engine and listen carefully. If the extraneous sound disappears, it means the ball bearing was humming.
We move the pulley. If there is play, the bearing needs to be replaced.

What kind of bearing is needed

Depending on the year of manufacture of the car, the generator can be old or new. They differ in shaft diameter: the new one is 17 mm, and the old one is 15 mm.

For a 17 mm shaft, bearing No. 303 is suitable.
Bearing No. 302 is suitable for a 15 mm shaft.
They have the same rear bearing No.202.

Bearing replacement

For work you will need: Phillips and flathead screwdrivers, 8 and 10 wrenches, 8 and 24 socket wrenches, a hammer. First you will need to remove the generator of the Lada Priora car, and then follow the sequence:

Remove the voltage regulator.
Remove the generator cover and remove the stator from it.
Using a spanner, unscrew the nut holding the shaft from turning.
Remove the pulley with the spring washer of the generator rotor shaft.
Press the rotor shaft out of the bearing.
Remove the 4 screws holding the bearing thrust washer.
Using a 24mm socket wrench and a hammer, press in the bearing.

Reassemble the product in the reverse order, starting with pressing the new bearing into the generator cover.

In stores you can find 2 types of belts for the Lada Priora 6rk1115 and 6rk1125. To avoid making the wrong choice, inspect the old belt to see if the size is still the same. If there is no size, take 2 belts, taking into account the possibility of returning one of them.

6р1115 — approximate price 242 rubles;
6р1125 — approximate price 345 rubles;

Common causes of generator failure

Avto-VAZ very often presents car owners with various surprises that arise during operation. One of these is the generator on the Priora, which can hardly maintain 60 thousand kilometers without problems. Once the numbers on the odometer exceed the specified value, malfunctions of this most important component on the car may occur at any time. A faulty generator makes it simply impossible to operate the car, since it does not produce the current necessary to charge the battery. Everyone is familiar with the purpose of a generator on a car, and if there are gaps in memory, then below is material that will help refresh your knowledge.

The service life of generators depends on various factors. This includes the manufacturing quality of the device, operating features, and even work on diagnosing and eliminating minor defects. Typically, their service life on budget cars is at least 5 years or 100-120 thousand kilometers. This is exactly the service life that, in theory, devices on Priors should have, but as mentioned above, these values differ greatly (it is important to note that this is not always the case). This is all due to the quality of the generators that the Priors are equipped with from the factory. These are devices of the famous or “LADA”, problems with which are known not only on the VAZ-2170, but also on other cars from the Russian concern.

Touching upon generator malfunctions on Priora, it should be noted that a common problem is not in the electrical part, but in the mechanical part. The reason lies in the rotor bearing, which, when it fails, produces a characteristic hum and grinding noise, indicating that the car owner is faced with at least the need to dismantle the generator. Such repairs are not at all complicated, but quite labor-intensive for known reasons. The biggest difficulty is removing the generator on the Priora, which is located between the engine and the radiator. Owners of the VAZ-2170, who have had to look under the hood of their car more than once, are well aware that the generator is located in a very limited space, and access to it is closed from all sides.

Interesting! An overtightened alternator belt leads to accelerated wear of the bearings.

The most common reasons why Prior owners need to dismantle the generator are:

Bearing failure. These elements fail more often than the brushes on the voltage regulator wear out.
Voltage regulator malfunction. The brushes on the device wear out, and the generated voltage to the battery also drops.
Worn slip rings or commutator.
Malfunctions of the diode bridge, which often occurs when moisture gets into the device, and as a result, oxidation appears.

In all of the above situations, you can repair the generator by replacing or eliminating defective elements. If the stator or rotor winding fails, then in such situations the unit must be completely replaced.

Interesting! If it is necessary to replace generator bearings on a Priora, you should choose products of the following types: B17-102DG38 - front support (has the following dimensions: outer diameter - 47 mm, inner diameter - 17 mm, width - 14 mm), 6202DW8 - rear support (outer diameter - 35 mm, internal diameter 15 mm, width - 11 mm).

How to tension the alternator belt

When checking whether the belt is tensioned on a Priora car, keep in mind that marks are applied to the camshaft pulleys. Rotate the crankshaft until the marks on the camshaft pulleys coincide with the cutouts on the reverse side of the drive.

With normal timing tension, the protrusion of the inner sleeve of the tensioner pulley should coincide with the opening of the outer race. If the belt is in good condition and the marks do not match 1/2 of the reach width, the tension should be adjusted.

Loosen the bolt holding the tension roller.
Make sure the cutout of the roller aligns exactly with the protrusion on the back of the roller bushing.
Using wrench 15, tighten the tensioner pulley bolt.
Simply put, to tension the belt, the generator roller needs to be turned in the opposite direction clockwise.

Powertrain Maintenance

The frequency of maintenance of the Priora engine by the manufacturer is 15 thousand km. It is recommended to carry out the first maintenance after 3 thousand km

The main attention should be paid to checking all attachment points for attachments. During the same service, the first oil and oil filter change is carried out.

If the engine is 8-valve, it is worth checking the valve clearances. For a 16-valve engine, this measure is not necessary, since hydraulic compensators are installed on this power unit. Similar work is carried out after 15 thousand kilometers of the Priora.

After the odometer reaches a value of 30 thousand km, in addition to changing the oil and oil filter, the spark plugs and power system filters require replacement. Often, at this mileage value, the timing tension pulley gradually begins to fail. If the Priora has an 8-valve engine, it will not be superfluous to replace the valve cover gasket.

When crossing the value of 45 thousand km, the oil is changed again

It is worth paying attention to the tension of the timing belt, and this applies to any engine, both 8-valve and 16-valve.

The next service is carried out after 60 thousand km. This time it is advisable to replace the alternator drive belt and spark plugs. It may be necessary to flush the power system, especially the throttle pipe. It is advisable to replace the idle speed sensor.

At 75 thousand km on an 8-valve engine, the timing belt and oxygen sensor are replaced. By this time, the coolant will partially lose its properties, so it is also replaced.

Further maintenance work on the Priora is repeated. Thus, it turns out that the minimum engine life is more than 100 thousand km. In some cases, with proper and timely maintenance, the mileage on a Priora without major repairs can be over 200 thousand km. Moreover, any intervention in the engine design, so-called tuning, can of course increase engine power, but this also reduces the life of the power unit.

Reasons for replacing the belt on a Priora and how to change it

The serpentine belt of the Lada Priora 2170 generator with air conditioning has a size of 742 mm, without air conditioning with power steering - 1125 mm. It must be replaced every time after 60,000 km of the vehicle, or two years after its installation. When the timing belt wears out, the valves may meet the pistons, which will lead to engine repair. An unscheduled replacement of the alternator belt of a Lada Priora 16 valve car with air conditioning may be required in the following cases:

delamination or cracks of the rubber surface;
folds and cracks on the inner surface of the teeth;
delamination of the end surface;
traces of technical fluids on the surface of the belt;
prolonged operation of a tightened belt.

Required tools and materials

Most motorists already have everything they need for this operation. Therefore, you won’t have to spend money on buying expensive equipment or consumables. The following tools should be at hand:

Wrenches with a diameter of 10, 13, 17 mm.
The collar is L-shaped.
Combination and socket wrenches with a diameter of 13 mm and 17 mm.
Screwdriver with star bit.
A prybar or small crowbar.
Flexible extension.
Lubrication - may be required to treat bolts that are difficult to loosen.

For convenience, you can replace the wrenches with a set of sockets with extensions. It is also advisable to put stops, otherwise the wheels may roll during repair work.

Replacing the drive belt on a car with air conditioning

The replacement process looks a little different on a car with air conditioning.
VD40 is used to process engine mounts and part bracket bolts.
The right front wheel is removed or turned out.
The generator roller is unscrewed. The belt is moved to the side and the engine mount bolts are unscrewed.
The Lada Priora needs to be jacked up so as to hang the engine.
We replace the old belt with a new one.
We lift the car with a jack, the engine is lowered and you will be able to tighten all the bolts.

Signs of trouble

Other manifestations may indicate malfunctions of the energy generator, for example:

dim headlights/dashboard;
unstable lighting brightness;
blinking or lighting of the indicator lamp on the instrument panel.

It is worth considering that the generator is partly interdependent with the battery. The generator is responsible for the electricity; the battery functions as a backup battery, which operates only during certain periods: when the engine starts and to supply power to the electronics when the engine is turned off.

Problems with power supply and voltage drops make it clear to the motorist that it is time for maintenance.
