Life hack: removing the generator on a Lada Priora car

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.

Causes of problems

Lack of power supply may be due to mechanical damage or disturbances in the electrical device of the generator.

In the first case it is:

• body deformation;
• violation of fixation (breakage of fastenings);
• wear of bearings, springs, couplings and other components.

Electrical problems on Lada Priora:

• interruption of the electrical circuit in the winding/short circuit;
• relay failure;
• disturbances in the conductivity of the diode bridge current;
• wear of carbon brushes;
• armature plate deformation/short circuit.

It’s good if the damage turns out to be minor, for example, wear of the carbon brushes. Then replacing them will solve the problem. In some cases, only a new unit can correct the situation. To replace the brushes, you can get by with freeing access to the dynamo without removing it, but replacement requires the complete dismantling of the equipment.

Given the differences in models, there are also nuances in removing the generator.

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:

1. Pulley - transmits mechanical energy through the belt from the engine to the generator.
2. 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.
3. 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.
4. 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.
5. Voltage regulator - maintains voltage stability in the on-board network when the ambient temperature and rotor speed changes.
6. Assembly with rectifier diodes
7. Diode module cover
8. The brush assembly is a removable structure where brushes are installed that interact with the rotor rings.

Selection of components

The original generator, installed on a car with a 16-valve engine at the factory, is marked with article number 5102.377. Its cost, as a rule, fluctuates around six to seven thousand.

Carefully check the generator itself and its packaging before purchasing so as not to encounter a counterfeit. It is important that the part is free of unevenness, chips and paint runs, as well as extraneous markings.

To avoid overpayments, you can purchase a similar original spare part. The following devices are suitable for installation on Lada Priora:

• VAZ (power 120/115a);
• KZATE (115a);
• BATE (90a);
• BOSCH (120a).

The price of analogues can be either higher or lower than that of the original. As a rule, it is in the region of 3500-6000 rubles. We choose a generator device with a large power reserve so that it lasts longer.

Keep in mind that installing less powerful generators is unacceptable, especially if you connect several different devices to the vehicle’s on-board network (when connecting a large number of electronics, it is generally recommended to increase the current). Before purchasing, we carefully check for damage to the case and the integrity of the unit.

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:

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

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.

1. For a 17 mm shaft, bearing No. 303 is suitable.
2. Bearing No. 302 is suitable for a 15 mm shaft.
3. 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.

Alternator belt - article price, how to tension

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;

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.

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.

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

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.

What signs will indicate that the generator brushes are faulty?

alternator brushesPriore

• length of the element being inspected;
• if upon inspection it is discovered that the length of the brushes is less than 5 mm, they must be replaced;
• Replacement will also be required if the appearance of the brushes indicates uneven wear, that is, one element is heavily worn out, and the second is brand new. To replace the alternator belt on a Priora, replace the lights on a Priora with your own hands;. Replacing the alternator belt on a Priora 16-cl. Replacing the alternator belt on a Priora. Replacing the air conditioner with a dual-zone climate. Without air conditioning and power steering. Of course, if there are no auxiliary units, then this repair will be somewhat easier to carry out, but in this case it requires an experienced one. Uneven wear of these elements will certainly negatively affect the operation of the generator, so experts recommend replacing them without fail.

The cost of new components for the Priora does not exceed 150 rubles; of course, you can also find cheaper brushes for the generator, but it is unlikely that such elements will serve faithfully for a long period of time, and such savings will lead to a repeated procedure for replacing these components.

If the replacement of worn brushes is carried out correctly, and the problem with charging the battery was precisely the wear of these components, then the car owner will solve this issue, and without the help of service station employees, which will save a lot of his own money. The replacement process itself is quite simple, but if difficulties arise during the work, you can watch the training video on the Internet resource at any time, which is provided by professionals, choosing the most suitable time for viewing.

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.
