Alternator belt for Lada Priora

Priora alternator belt size

To choose a Priora alternator belt, you need to check whether the car has air conditioning and what brand it is. You can find the difference between the Halla and Panasonic systems by the following points:

The extreme right regulator (responsible for air speed) on Panasonic has more than 15 positions, while Hull has only 4.
When you press the middle Panasonic button, the air conditioning and windshield defogger mode are turned on. On Hull this button does not function (a plug is installed).

There are also differences under the hood: with the Panasonic system the hose is rubber, with the Hull it is aluminum.
The Priora generator belt with air conditioning without power steering for the Halla system and the Panasonic system is marked 6РК1115.

How to repair a generator

Now you know how to unscrew the pulley, remove the belt from the generator and replace it on a Lada Priora car, which can come with or without air conditioning and power steering.

But it’s worth saying that the generating device on the Lada Priora is definitely not the weak point of the car. According to technical documents, preventive checks should be carried out at intervals of 50 thousand kilometers. And this despite the fact that in practice the resource of the node is much higher.

In terms of repairs, brushes are usually changed every 150 thousand kilometers. Other elements are designed to last a lifetime.

But there is an important nuance. Brushes, as a separate element, cannot be changed on the Lada Priora. They are an integral part of the voltage regulator. The latter cannot be repaired. That is, it will have to be replaced entirely.

It's nice to know that a new voltage regulator is inexpensive. The cheapest options will cost 200-300 rubles. More expensive parts cost 600-800 rubles.

There is no specific serial number to search for the original generator, since Lada Priora is equipped with spare parts from different manufacturers, as well as with different characteristics. These are brands such as Orbita, VTN and Energomash.

Therefore, when they talk about how to change the brushes from a generator on a Priora, they mean buying a new voltage regulator with brushes assembled.

They can be changed by removing the generator or without prior dismantling.

Repair without removal

If you have a simple Lada Priora equipment, which does not include air conditioning, then replacing the brushes without removing the generating device itself will not be difficult.

To do this you need:

disconnect the battery;
remove the power wire from the generator;
disconnect the control lamp input;
unclip the 3 latches to remove the plastic protective cover;
unscrew only 2 fasteners that hold the regulator together with the brushes;
replace the voltage regulator;
Reassemble in reverse order.

Be careful and careful when removing latches. Many owners of Lada Priora complain that it is quite inconvenient to snap them off. Losing patience, they often make sudden movements, and the latches eventually break. Be careful and patient. No other way.

After this, do not forget to check the correct operation of the automotive electrical system with a new part.

This option is optimal for replacing the regulator if the air conditioner is not included in the package. This is due to the presence of sufficient space in the area where the unit is located. That is, there are no problems with sticking your hand into the gap and performing all the manipulations.

Now to the question of whether it is possible to replace the regulator without removing the generator, if air conditioning is included in the package. Replacing the brushes and regulator assembly itself is no different. But there is another problem. This is the lack of sufficient space to stick your hand through and perform operations. There is no required gap between the engine and radiator. This is especially a problem for people with large hands.

In addition to trim levels with air conditioning, a similar situation is observed on Lada Priora with a 16-valve engine.

But there is a solution. It is necessary to disconnect the air filter housing and then move it to the side, or completely dismantle it. As a result, there should be enough space to avoid dismantling the generating device.

Belt life

Drive manufacturers claim that the alternator belt for the Lada Priora is 16 cl. without air conditioning it can last 120 thousand km. This is acceptable if all systems work flawlessly and no external factors affect this part of the car. But in reality this is not the case; the operation of the belt is affected by many things, including temperature changes.

Recommendations from experts and Prior owners boil down to the fact that it is better to change the drive every 50-70 thousand km, provided that high-quality spare parts are used.

Important feature of Lada Priora

When planning to solve an issue related to a belt or alternator with your own hands, it is important to consider one point. This is the equipment of the car.

The thing is that Lada Priora can be without power steering and air conditioning. And the procedure for carrying out repair work largely depends on this.

So the replacement instructions need to be considered taking into account whether the Priora has air conditioning or power steering or not.

Alternator belt problems

There are several main signs that it is time to change the alternator belt on the Priora 2172. And if some of them are harbingers of small costs, then some can lead to costly repairs.

Why does the alternator belt whistle?

One of the obvious causes of whistling is water entering the drive. The rubber becomes wet and may make a long-drawn sound when moving for a few seconds. From a heated engine, the moisture quickly dries out, and the squealing should disappear. If the sound appears on a dry, hot day, it means that the drive itself has stretched and should be replaced or the tensioner rollers tightened.

Also, squeaking can occur in winter, during cold times, when the rubber becomes hard and adheres less tightly to the working surfaces. The same heat from the engine makes it more elastic, and it takes its original shape, pressing against the generator pulleys.

Another reason for the formation of a whistle is the simultaneous inclusion of all electrical appliances in conjunction with the air conditioner. If the drive has been in use on the car for some time and has even minor defects, then such a load will be accompanied by an audible sound.

Why does the Priora alternator belt slip?

In addition to water, due to which the drive temporarily loses tight contact with the rollers, its slippage is also affected by the belt mileage. If the new spare part is pressed very tightly against all the rollers, then over time the rubber stretches and may slide when the engine starts. A similar effect is formed due to cracks that appear on the surface of the drive during operation.

Why does the alternator belt “eat”?

A problem that does not occur often, but causes confusion among many car owners - the drive begins to become shaggy on one side. This is due to the destruction of the pulleys, which for various reasons stop working stably. Increased scrolling resistance under load causes the belt to move slightly from side to side, touching other surfaces.

Why does the alternator belt fall off?

If in one case the drive can be “eaten up”, then in another case it can fly off. This happens due to clogging of the working surfaces of the drive and pulleys. Dirt gets clogged, compacted tightly and creates an uneven surface, causing the belt to slip and move out.

A weakened belt tension can also affect belt failure. This happens either due to wear and tear of all elements involved in the drive (their service life is coming to an end), or due to the installation of low-quality components.

How to change a generator

Next, you will learn how to remove the generator on a Priora if the car comes with air conditioning or power steering, or was supplied from the factory in a simple configuration.

This point is really important. Often, car owners repair the generating device without removing it, since dismantling turns out to be too problematic.

Let's start with the budget configuration, which does not have air conditioning or power steering. To work on removing the generator, you will need a pit or a convenient overpass.

The process of removing a generator on a Priora without air conditioning looks like this:

disconnect the battery (just disconnect the negative terminal);
remove the engine protection;
loosen the generator tension roller;
pull the belt off the pulleys (it is not necessary to completely remove the belt);
disconnect the wire block from the D+ connector;
disconnect the wires from the contact pin;
slide the rubber cover under which there is a fastening nut;
unscrew the nut of the lower clamp, and then remove the screw of this clamp;
then unscrew the fastening nut located on the upper bracket;
first move the generator down and then to the right;
unscrew the adjustment screw;
remove the tension bar;
make sure that the generator is no longer connected to any wires;
remove the device from the car.

Sometimes the procedure for removing the generator is complicated by the fact that the lower mounting bolt is not very conveniently installed. It is impossible to pull it out completely, since it rested against the cushion of the Priora’s power plant.

In this situation, you can do this. First, the engine is hung out, and then the engine mounts are unscrewed. Now the bolt can be pulled out without any problems.

Or an alternative, more barbaric method. The bolt is simply cut off and a similar fastener is installed in its place.

Do not forget to perform reassembly in the same way as dismantling. Otherwise, serious problems will arise in the future, as well as difficulties in disassembling this unit.

This is how the generator is replaced if the Priora does not have power steering or air conditioning.

If the Lada Priora has air conditioning or hydraulic booster installed, then the issue of removing the generator to repair it becomes more acute. Yes, if the unit needs to be replaced, there are simply no options. But for repairs, many prefer to carry out work without removal.

The problem with the configuration with an air conditioner is that the removal of the generator according to the scheme discussed above is prevented by the air conditioning compressor. That is, the compressor is supposed to be removed here. And this is difficult and financially expensive if you contact a car service.

Craftsmen and Lada Priora owners have found an alternative solution. Even with air conditioning, the generator can be removed without touching the air conditioning compressor. To do this, the headlight is removed.

In this case you should:

dismantle the protection over the optics;
loosen the front bumper fastenings;
remove the headlight;
gain access to the generator.

Further, the principle is similar. That is, the battery is disconnected, the belt is removed, the fasteners are unscrewed, the wires are disconnected and the generator is brought out through the gap cleared by removing the headlight. And the connection diagram for the new generator on Lada Priora cars is the opposite of turning it off.

You can find information that removing the compressor to dismantle the generator is only possible if the Lada Priora has an air conditioner manufactured by the Halla brand. If there is climate control equipment from Panasonic there, then you can remove the generating device without removing the compressor. Whether this is true or not has not been officially confirmed. But you can leave a comment and tell us what you know about this.

The subsequent connection of a new generator installed on a Lada Priora car is carried out in the reverse order.

When to change the alternator belt

Whether the Priora alternator belt needs to be replaced with or without air conditioning can be determined by several signs:

The permissible mileage has reached 70 thousand km (it is advisable to visually inspect the drive every 15 thousand km).
When examining the inner working surface of the belt, there are cracks, abrasions, and tears.
After adjusting the roller, the belt tension remains insufficient.

It's also time to change the belt if you feel vibration in the drive.

What to do if the alternator belt breaks

Anything can happen on the road, and we cannot exclude those moments when, for some reason, the generator drive breaks. If this happens, you can carry out a simple procedure to replace it with improvised means and go to a service station or auto store to purchase an original spare part.

A strong rope or women's tights folded into a narrow strip are suitable as a substitute for the drive.

We lower the tensioner to the limit to facilitate installation of the temporary drive.
We put a rope on all the rollers.
We return the tensioner to its original position, checking the deflection of the rope (it should not be more than one centimeter).

On cars without power steering or air conditioning, the replacement method is slightly different:

Loosen the top nut of the generator.
We tighten the tension bolt to bring the generator closer to the engine.
We install the rope.
We unscrew the tension bolt, moving the electric generator away from the engine.
Having achieved the required tension, tighten the upper fixing nut.

If this happens within the city, and the car has a good battery, you can immediately go to a repair shop or store. The battery charge lasts for 20-40 km, but to be sure of covering such a distance, you should turn off all electrical appliances.

How to lubricate the alternator belt tensioner roller

Lubrication of the roller is necessary so that the bearing moves more easily and does not create additional resistance to the movement of the drive. This can be done without removing the roller itself. Initially, select a lubricant:

lithium lubricants (most often used “Litol-24” or “Ciatim-221”);
CV joint-4 is best manifested in medium and high temperature conditions;
synthetic lubricants are not washed out by water, therefore they are recommended for regions with high humidity.

Having chosen the product, you can begin to lubricate the roller:

Using a flathead screwdriver, carefully remove the boot from the tensioner.
Fill the syringe with no more than 1 cubic meter of lubricant.
Insert the needle into the gap from the boot and move it around the entire circle, smoothly squeezing out the contents of the syringe.
Start the engine so that the lubricant is evenly distributed on the roller.

After this, turn off the engine and replace the boot. Excess lubricant should be carefully removed with a cloth or sponge so that it does not get on the belt during operation.

How to tighten the alternator belt on a Priora

If the drive, after inspection, is in good condition and does not require replacement, but the driver is bothered by noise from the generator (short-term squealing), try changing the belt tension.

If the Priora is 8-valve without additional equipment, then tensioning is carried out by an adjusting bolt located on the generator. Turning clockwise will increase the drive tension.

When it is necessary to tighten the alternator belt on a 16-valve Priora with air conditioning, adjustment is carried out using a belt tensioner. This video has two holes for a special key (if you don’t have one on hand, you can make a bracket to size from any bendable metal). It is necessary to insert the key and slowly turn it either toward you or away from you, depending on whether you want to tighten or loosen the drive.

Replacing the belt included with power steering

The nuance of the Lada Priora configuration with hydraulic booster is that the power steering pulley is at a low height. Therefore, the generator belt was eventually run around the power plant support.

Because of this, the process of dismantling and replacing the belt has become more difficult. The required set of tools has also expanded, consisting of:

set of keys;
tension wrench;
jack;
set of heads;
WD-40 products.

The step-by-step process is as follows:

using WD-40, treat the bolts that secure the engine mount and bracket;
wait 15-20 minutes and try to unscrew the bracket nuts;
use a jack to lift the wheel on the generator side;
place a strong object under the engine and remove the wheel;
lower the car a little;
unscrew the tension roller;
bend the belt;
unscrew the bolts holding the pillow;
lower the car so that the engine begins to hang out a little;
move the pillow towards the engine;
remove the belt and install a new one;
lift the car with a jack so that the engine returns to its original position;
At the same time, make sure that the pillow and the belt do not move;
tighten the nuts and bolts tightly;
Replace the wheel and lower the vehicle completely.

That’s it, this completes the procedure for replacing the alternator belt using the example of a Lada Priora car, which has power steering. As you can see, there are much more difficulties here than in the version without power steering.

A similar replacement is carried out if the Lada Priora is equipped with air conditioning from the factory.

Alternator Belt Adjustment

How to tighten the alternator belt on a Priora 2170 is described just above; you need to check that its tension is correct:

It is necessary to create pressure on the drive between the camshaft discs (you can press hard with your finger) and see how much the belt bends. The permissible deflection is 5-6 mm. If the drive does not flex, you should loosen the tension; if you push it with your finger more than one cm, you need to increase the tension.
There are special marks on the roller that you can use to guide you when adjusting the tension. This applies only to a correctly selected new belt and at the time of its initial installation.

If the adjustment is incorrect, the following points appear:

Weak belt tension creates a voltage dip (the battery icon on the dashboard lights up, the headlights shine dimly).
If the drive is overtightened, the generator bearing will be under too much load and will operate with a loud hum, and will also quickly fail.

Replacing a belt in a configuration without power steering

If power steering, that is, power steering, was not included in the configuration of the Lada Priora car, then the instructions will have a certain form.

It is best to drive the car into an inspection hole to carry out work. Among the tools, you should arm yourself with a wheel wrench, a set of regular keys, and also a puller for the fender liner.

The process of replacing a belt on a Priora, where there is no power steering, looks like this:

loosen the generator mounting nut;
unscrew the adjusting bolt;
move the generator towards the engine;
remove the front right wheel;
remove the fender liner to gain access to the belt;
remove the belt from the rollers;
install a new spare part.

At the same time, check that the tension is correct. There are recommendations here, which you will learn about a little later.
