Priora generator belt tension key

The Lada Priora, created on the basis of the VAZ 2110 sedan, belongs to the family of Russian small cars. The model was produced in various configurations with different drives for auxiliary units.

For example, the base model has a conventional alternator belt tensioning mechanism. At the same time, in cars equipped with air conditioning or power steering (power steering), the trajectory of the alternator belt is slightly different.

Accordingly, replacing the alternator belt on a Priora without air conditioning is a little easier than on a Priora with air conditioning. Let's consider the algorithm for replacing a belt with different types of drive.

Tensioning the alternator belt: a guide for car enthusiasts

The distinctive features of the Priora from previous modifications of the manufacturer are noticeable immediately, literally as soon as we open the hood. Here the new owner of the Lada will have to learn a lot again. This seemingly not very complicated procedure, which allows you to tighten the alternator belt in a Priora car to the required limit, will require considerable effort.

The peculiarity of new car models is that the ability to choose a car equipped with optional equipment is already present as standard. So in the “base” “Priora” can already be equipped with power steering or air conditioning.

Naturally, driving the car becomes even more convenient, but the recompense for comfort in this model is a more complex design of the generator belt drive. After all, the belt itself on a Priora car, which has air conditioning or power steering, is significantly longer, has a more complex trajectory, is serviced and replaced according to completely different rules.

Tensioning the alternator belt in a Priora car - nuances of implementation

Any car enthusiast knows that there will definitely come a time when you need to tighten the Priora alternator belt. It is known that the belt drive of this car is quite durable, but during operation there is a slight stretching of the belt itself, as well as a decrease in the adhesion of its surface to the pulley and roller.

Literally as soon as you notice a whistling alternator belt on a Priora, you need to start tightening it at the same moment, especially since this is not difficult to do.

Before tensioning the Priora generator belt, you need to prepare an open-end or socket wrench for 19 and a special two-end tension wrench directly for the roller. This key is similar to the one used to change discs on an angle grinder.

Step-by-step instructions for replacing the alternator belt with power steering on a Priora

Replacing the alternator belt on your own on a domestic Lada Priora, if it also has air conditioning, is a completely feasible task that will not take you much time, and you will also need a minimal set of tools.

List of required tools:

The key is 17.
Driver/ratchet.
Head for 12.
Key for tightening the roller.

Let's start replacing:

Using the prepared wrench, unscrew the belt drive roller. It will gradually weaken and then it can be easily removed. This part must be unscrewed, since without this procedure the belt cannot be removed in any way, because it goes on top of the power unit mounting pad. It is necessary to remove 2 bolts that secure the motor mount.
Then you need to jack up the power plant. Just at this very moment a slight gap forms between the support and the body of the Lada Priora.
Through the resulting gap, you can remove the worn alternator belt and install a new one in place.
We remove the worn belt. In the photo below you can see this process

In order to maximize the distance between the “engine” and the support, you will have to try and “play” with the position of the front body and the engine. However, when performing this action, you will not encounter any difficulties, everything is very clear.
We remove the belt from all the pulleys, and you need to push it down so that it can be easily removed.
Through the bottom we replace parts, including: the drive roller of the units. Change it if there is any play or noise. The accessory drive belt is also removed.

By and large, replacing the alternator belt on a Lada model with air conditioning is not at all a complicated procedure; as you can see, it is carried out quite quickly and smoothly. However, that's not all. Next, an equally important procedure is performed, such as belt tensioning.

Checking the tension of the alternator belt on a Priora

Owners of a Priora car can know how to tension the alternator belt from numerous sources on the Internet and by reading the relevant literature. After all, any car enthusiast will learn how to properly tighten the alternator belt on a Priora from these sources, and not through the transfer of experience from other car enthusiasts. But some “tricks” associated with checking tension cannot be found even in the above sources. Let's take a closer look at them.

If you press on the belt at the longest interval directly between the pulleys, then its deflection should be within 8-12 mm, but this rule is only suitable for a very modest car configuration. After all, if the car is equipped with power steering or air conditioning, the belt then has a different trajectory, which helps reduce the area of interaction between the belt and the pulleys.

To make up for the lack of contact, you will need to tighten the belt on the Priora a little more. If it is not possible to use the services of a specialist, then you can try adjusting the tension of the Priora generator belt “by ear”. If the tension is insufficient, the belt will definitely slip, making a wild “whistle”, and if the tension is too strong, the generator bearings will hum.

How to replace a Priora alternator belt with air conditioning

The process of replacing a belt on a Priora with air conditioning is slightly different from replacing a belt without air conditioning. It will take longer, but you can still carry out the replacement yourself, without going to a service station.

Necessary tools and materials: belt code 6PK 1115, set of keys and sockets, jack. General procedure:

spray WD-40 liquid onto the bolts of the cushion to “bounce”;
Unscrew the tension roller of the Priora generator clockwise using the “17” key;
unscrew the engine mount mounting bolts using a TORX E10 head;
place a jack under the front right side of the car and remove the wheel;
remove the side mudguard by unscrewing the screws and place the stop under the engine crankcase;
slowly lower the car on a jack (until the engine is raised above the body) to gain access to the belt;
remove the old belt by loosening the fastening nuts;
install a new alternator belt, check whether it is seated on the air conditioner pulley;
screw the tension roller and tighten the alternator belt;
raise the car and remove the support from under the engine crankcase;
screw on the engine mount of the car and check the quality of the drive by starting the engine and turning on the air conditioning;
return the plastic mudguard and the removed wheel to their place;
lower the car from the jack.

At this point, the belt replacement can be considered complete. The only thing is that experts recommend checking the belt tension again after 2-3 thousand kilometers. If the belt is slightly slack, the alternator belt will need to be tightened.

Tensioning the timing belt on a Priora: user instructions

In addition to the alternator belt in a Priora car, another important component is the timing belt. For this reason, many car enthusiasts are wondering how to tighten the timing belt on a Priora? It is not difficult to carry out this procedure; it is enough to prepare a tool: a “5” hexagon, a “17” and “15” head.

Before tightening the Priora timing belt, you should:

— unscrew the two screws securing the cover;

— remove the bottom cover covering the timing drive;

— insert the tips of the pliers into the grooves of the outer race of the tension roller in order to remove the locking rings.

- tighten the belt by turning the tension roller directly with pliers, counterclockwise.

— these actions are performed until the cutout of the outer race is aligned with the rectangular protrusion of its inner sleeve;

— after the above steps, the roller mounting bolt is tightened with a wrench;

— we check that the marks on the camshafts and crankshaft are aligned, as well as the cutout matches the mark on the tension roller. If the marks do not match, you should repeat the operation to tension the timing belt.

ALTERNATOR BELT TENSION ROLLER FOR VEHICLES WITH STEERING OR AIR CONDITIONING

The Priora, equipped with various options, has an alternator belt more than a meter long. It passes through four reference points. Three of them are pulleys. The first is the engine drive pulley and the second is the generator and power steering pump or air conditioning compressor. The fourth point is the tension roller itself. This simple mechanism is made in the form of a regular rolling bearing, with an eccentric base. That is, when turning it around its axis, thanks to the hole for the bolt, located not in the center of the bearing, but offset to the edge, the protruding part can tighten or loosen the drive belt of all additional Priora mechanisms.

Symptoms of malfunction and their elimination

You can determine whether a replacement is needed or whether you can simply tighten the power steering belt with air conditioning on the Priora 16 valves only after inspecting this component. To do this, just open the hood and examine the belt; it is located next to the right front wheel. There are signs that indicate it's time to check the alternator belt: something whistling and squeaking from under the hood.

The reasons may be the following:

Antifreeze, oil or other working fluids have come into contact with the generator pulley or belt.
The belt is worn out - you can tell by its appearance.
The tension has dropped - in this case, the component must be tightened.
The bearing in the generator is worn out.

When the belt whistles in a Priora with 16 valves, it’s time to carry out diagnostics. If there are cracks, tears or other serious damage on its surface, then replacement is required. If the generator component with hydraulic booster and air conditioning looks normal, you should check its tension; the optimal level of deflection is 6-8 mm - you need to press the component in the middle between the generator and the pulleys.

Are there visible coolant or engine oil stains on the surface? If the contamination is not significant, they can be cleaned. If the liquid has penetrated into the material, cleaning will not bring any results; replacement is needed. If the component is well tensioned and no damage or stains are visible, then you should move on to checking the bearings. They may need to be changed.

Sometimes the generator consumable whistles due to the poor quality of the product. This is especially true for Chinese analogues, which are not of high quality. Such a belt whistles a lot already at the fifth thousand mileage, it is better to change it immediately. We recommend purchasing consumables designed for your model, in our case, for a Priora with a 16-valve engine.

TENSIONER FOR PRIORA AND KALINA NOT EQUIPPED WITH OPTIONS

On the Priora, which does not have power steering or air conditioning, the belt is much shorter. It works on only two points: the crankshaft pulley and the generator pulley. The latest samples are equipped with a tensioning system similar to the VAZ Kalina. That is, if on other VAZ cars the tension is done by moving the generator itself, then on the Priora, a plastic roller of the tension system presses on the drive from above. A special tensioning mechanism is installed to move the roller. It consists of several parts:

The entire system is clearly visible in the photo. To adjust the drive and replace the tensioner, the following keys are needed. Slip on 19, end and socket on 13 and any wrench on 8. First, loosen the bolt and nut holding the movable platform with the roller with a wrench on 13. Then release the lock nut securing the adjusting rod using a wrench on 19. Using a wrench or socket on 8, unscrew the adjusting rod cravings The generator remains motionless. When the belt is loose, unscrew the bolt with the bushing on which the desired part is attached. Now remove the roller and install a new one in its place.

Check the free rotation of the tensioner for the generator drive and, having tightened the rod to the normal state of the drive, securely fix all the fasteners.

Replacement

Required Tools

We will prepare everything necessary for the repair:

Lubricant WD-40.
Keys to 19, 17.
Two copies of the key for 13.
Head for 10 and 17.
Jack.
Special key for tensioning.
Lever arm.

The alternator belt on a modified Priora with air conditioning and power steering runs around the engine mount. The designers decided to carry out such a modification for the Priora 16 due to the fact that the power steering pulley is installed low. Hence there are additional steps that you need to be aware of.

Step-by-step instruction

First of all, we need to wet the bolts that hold the bracket and motor mounts. Wait 10-15 minutes for the lubricant to spread over the surface;

The replacement is complete, all that remains is to adjust the alternator belt with power steering and air conditioning. The new consumables on the Priora will have to be tightened several times until you get the required tension. If the component whistles or there is a hum coming from under the hood, then it is necessary to carry out repeated adjustments until these defects are eliminated.
