Belt tensioner pulley for Priora generator 16 valves with air conditioning article number

On Priora cars equipped with additional options, such as hydraulic power steering or air conditioning, due to the specific location of the units and, accordingly, the drive belt of the mechanisms, the tension of this drive is arranged using a tension eccentric. The tension roller is also used on the latest releases of the Priora car. This tensioning mechanism is modeled after the tension of the Kalina drive belt. Due to differences in design, tensioners are available in two types:

metal plastic with options;
plastic for standard vehicles.

How to adjust the generator roller on a Priora with your own hands

The generator belt tensioner roller is a small but very important part of the machine. If it fails, the operation of attachments and electrics is at risk. But you can diagnose, lubricate and even change a spare part yourself; it does not require much effort or serious knowledge in the automotive industry.

On Lada Prioras with air conditioning and power steering, as well as those equipped with power steering (electric or hydraulic power steering), the alternator belt is additionally maintained in an optimally tensioned state by a special roller. The Priora generator belt tension roller is an important part that ensures the operation of the attachment.

How to determine the need for replacement or adjustment

The condition and tension of the belt must be checked at least once a quarter.

This will allow you to quickly detect weak tension or damage to the belt. A whistle that appears when starting the engine and accelerating the car indicates weak belt tension. Rapid battery discharge (as well as weak charging current) may also indicate a loose alternator belt. The service life of a high-quality alternator belt is 40–60 thousand kilometers or 2 years. After this, the belt must be replaced, even if it looks normal. If cracks or breaks appear on the belt, it must be replaced, regardless of mileage. To determine the condition of the belt, it is necessary to carry out diagnostics.

Where is the Priora generator roller located?

The tension roller of the Lada Priora generator belt is used to hold the auxiliary drive belt on the pulleys of the drive device; it is responsible for a tight fit and preventing slipping.

The drive belt in a Priora with 8 or 16 valves is located under the hood on the right side of the engine (along the direction of the car). If you look directly at the assembly, the bypass roller will be located on the top left, it is clearly visible. This is noticeable in numerous photos of the Priora’s engine compartment available on the Internet, and in videos with instructions for repair and replacement.

The part is of an eccentric type and is visually distinguishable due to the off-center bolt.

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.

Important! Carefully monitor the installation of spacer washers under the bushing, otherwise the new roller may jam.

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.

Which generator roller is better to install on the Priora?

Of the good non-original “prior guides” note:

Hofer (HF code 608230);
Gates (T39176);
Lynx (PB-5039);
Trialli (CM170);
Marel (2110).

Less common are accessories from INA and Andycar. Among the inexpensive and fairly popular options for replacing the tension roller of a Lada Priora generator belt with air conditioning or power steering, we can highlight the products of the Vologda Bearing Plant - the VBF roller (catalog number 830900AKE). But reviews from car owners indicate the “floating” quality of VBF parts, and their purchase should be approached with caution. Many people advise installing Gates spare parts.

There are also drive belt repair kits supplied with this part, for example, Trialli GD613.

Panasonic Priora air conditioner clutch bearing

Article tags: bearing replacement, bearing noise, bearing selection
Such a procedure as replacing a bearing in a car air conditioning compressor is performed quite often, and there are completely objective reasons for this. The fact is that this part experiences increased loads, since it is forced to function whenever the engine is running, even regardless of whether the driver turns on the air conditioning or leaves it alone.

The fact that replacing the air conditioner compressor pulley bearing is really necessary and cannot be delayed in any way is evidenced by an unpleasant extraneous hum that occurs every time the car’s power unit starts. It is noteworthy that it manifests itself in different ways and under different conditions: sometimes only after the engine has warmed up, and sometimes only, as they say, “when the engine is cold.”

If noise occurs from the engine compartment, it is urgent to identify the source of the noise. Most often it is created by the drive belt rollers. But, if you clearly understand that the sound is coming specifically from the air conditioning compressor, then the reason for this, with a high degree of probability, is the air conditioner clutch bearing.

You should go to a service station so that specialists can accurately diagnose the cause and take all necessary measures to eliminate it. As a rule, if a bearing is noisy, then the degree of its wear is such that it needs to be replaced in order to avoid destruction of the part, which can lead to quite serious consequences.

Signs of tensioner failure

The following symptoms indicate poor adjustment or failure of the unit:

whistling, increased noise, rustling from the generator unit (extraneous sounds are not necessarily associated with the tensioner, but may indicate its misadjustment or malfunction);
hum and buzzing that occurs when the belt roller bearing of the Priora generator wears out;
vibration of the roller and belt, indicating a worn bushing;
too much belt deflection (more than 8 cm) or excessive tension (less than 0.6 cm) - if detected, adjustment must be made;
the fastening bolt begins to heat up;
backlash in the tension roller (this, like the hum, indicates a worn bearing);
uneven wear and stretching of the belt on one side (as a rule, this sign indicates a bend in the tensioner bracket).

Lots and lots of modern details already fill the precious Priora. But the most important thing is the irreplaceable Panasonic Priora air conditioner. But many have little budget and cannot afford the Priora equipment above the basic one. And the basic one, alas, is not equipped with air conditioning. And in this case, an excellent solution was found. You can buy a basic Priora and simply install the air conditioner yourself later.

Read about what kind of air conditioner is installed on a Priora, how it is installed, and where it can be installed.

How and with what to lubricate

If the check reveals a lack of lubricant, it can be changed. You can use Litol-24.

To lubricate the tension roller of the Priora 16 class generator, you should:

Dismantle it.
Remove the anthers.
Wash the tensioner to remove any remaining old grease (this will also help to visually check the condition of the bearings).
Apply a layer of Litol.
Reinstall the anthers, mount the eccentric roller and check the tension.

In addition to Litol, the CRC lithium-based consistency demonstrates good qualities. It is resistant to high temperatures and rotation speeds. Chevron Delo Grease EP NLGI 2 has similar properties; the authors of repair video guides often recommend lubricating the mechanism with it.

It is important not to apply too much lubricant, otherwise it will begin to squeeze out onto the belt.

Tension check

Tension checking process

Now let's look at the issue of checking tension. It’s worth mentioning right away that the force values are unique and depend not only on the make and model of the machine, but also on the generators and belts used. Therefore, look for the relevant information in the manuals for your car or in the operating instructions for the alternator or belt. This will also be influenced by the presence of additional equipment installed in the car - power steering and air conditioning. In general terms, we can say that if you press the belt on the longest section between the pulleys with a force of about 10 kg, then it should deflect by approximately 1 cm (for example, for a VAZ 2115 car, when applying a force of 10 kg, the belt deflection limits are 10 .15 mm for generators 37.3701 and 6.10 mm for generators type 9402.3701).

How to tension a roller

After replacement or dismantling and subsequent return to place, the roller must be adjusted for proper operation of the drive mechanism. To work you will need tools:

Size key
Special key for tightening. It is a structure welded to the base in the form of a pair of rods with a gap of 18 mm between them (similar to a key for an angle grinder). The rods are designed for insertion into technological holes on the roller.

How should the belt be tensioned?

The eccentric roller retaining bolt must be loosened.
Clamp the roller cage and turn the part counterclockwise or clockwise with the adjuster key, increasing/decreasing the belt tension. At the longest section between the pulleys and the shaft, it should bend by about 6 mm.

When the desired result is achieved, the fastening is finally tightened.

Tension using adjusting bolt

Adjustment with a bolt on a VAZ-2110

This method is more progressive and is used in most modern machines. It is based on the use of a special adjusting bolt , by turning which you can adjust the position of the generator relative to the engine. The algorithm of actions in this case will be as follows:

loosen the generator, its upper and lower fastenings;
Using the adjusting bolt, we change the position of the generator;
fix and tighten the generator mount.

The belt tension level in this case can be determined during the adjustment process.

How to check the generator roller

After diagnostics with removal, lubrication, replacement or adjustment, the roller must be checked. After completing the adjustment, check the tension according to the diagram:

manual control by pressure - a correctly tensioned belt should not bend by more than 0.8 cm;
start the engine;
turn on all possible energy consumers - air conditioning, heating, high beams.

If all components are working properly and there is no extraneous noise coming from the generator, the setup is correct. If there is a whistling sound, the belt is most likely under-tensioned, and if the bearings are humming, it is likely to be too tight. The procedure should be repeated more carefully, controlling the tension. Normally, the belt should bend by 0.6-0.8 cm when pressed.

General questions about working with the Grant generator

How to adjust headlights with your own hands

Let's consider general questions: everything except replacement.

Tension check

There are two approaches: visual assessment and physical.

Visual assessment of condition:

the car is on a flat surface, the gear is in neutral, the handbrake is off, the hood is open;
We don’t start the car - we put it in 5th gear;
We opened the hood and found a generator: we push the car back, resting against the bumper;
We inspect the required part along its entire length: are there any breaks or cracks? It needs to be changed.

Poor quality will lead to unexpected problems on the way. Physical assessment:

if you have a tool that measures pressure force: press the belt with a force of 10 kg*s - the deflection should be no more than 10 mm;
there is no special tool: we try to turn it across - it should turn no more than 90 degrees.

How to tighten the alternator belt on a Grant

This section applies only to machines with a tensioner. No - change the part or see above how to install it.

Subsequence:

we use ring wrenches 8, 19;
Throw key 19 onto the lead screw;
wrench 8 for locknut;
we touch;
Now you can turn the lead screw: clockwise to loosen, counterclockwise to tighten;
got the desired result - tighten the locknut.

It is better to take ring wrenches, since a head with a ratchet or a wrench will not work.

When to change: technical regulations for replacing a VAZ 2190 belt

AvtoVAZ requires checking the condition of this part every 15,000 kilometers.

Replacement is required every 30,000 kilometers, regardless of condition.

How to remove a generator on a Grant

It needs to be removed for repairs, replacement of bearings or rollers.

The step-by-step process involves:

remove the negative terminal from the battery;
working with the generator: disconnect the wiring harness from it;
remove the cover of the power wire nut, remove the nut and remove the wire from the bolt;
unscrew and pull out the upper and lower fastening bolts - to work with the lower one, you may need to climb into a hole, throw off the tin protection of the internal combustion engine and dismantle it from below;
move the part to the right mudguard, remove the belt, and remove it.

You can do without a hole. Example:
