The timing belt (Timing Belt) is a closed rubber belt with notches on the inside. It is designed to synchronize the engine crankshaft and camshaft.

What timing belt is installed on Priora and Kalina from the factory ? Standard timing belts for Niva Chevrolet and Lada Priora, Kalina from GATES (Gates). Belt part number: 21126-1006040 (5631XS).

The price of a timing belt starts from 1200 rubles. and depends greatly on regions.

How to properly replace a timing belt

To prevent the drive belt from breaking and repairs, it is necessary to promptly replace and tighten the product. Work on replacing and adjusting tension should only be carried out on a cold engine.

Tools

What you will need to complete the task:

• set of wrenches;
• a device for installing and adjusting the tensioner, can be purchased at a car store;
• ruler or construction tape;
• two screwdrivers - with a flat blade and a Phillips blade;
• set of star keys;
• clean rags.

Channel In Sandro's garage, I made a video showing the procedure for replacing the timing belt on a 16-valve Priora engine.

Instructions with pictures

Below is a detailed description with photos of how to install a new belt and correctly align it with the marks:

1. Using a star wrench, remove the five bolts that secure the upper timing cover. Dismantle it.
2. Turn the engine crankshaft clockwise until marks 1, which are located on the camshaft toothed disks, are aligned with marks 2 located on the rear cover of the unit drive. If, as a result of the above actions, the pulleys continue to rotate, do everything again, but now the crankshaft must be turned two turns. To align the marks, the screw securing the tensioner pulley must be turned using a 15 mm wrench. It is advisable to maintain a tension torque of 20-25 Nm, but this cannot be done without a torque tool. Set the crankshaft and camshaft to the top dead center position of the compression stroke of the first cylinder.
3. To check the position of the crankshaft, remove the rubberized plug from the top of the clutch housing. It will be more convenient to disconnect the cooling system pipes, and also disconnect the connector with wires from the refrigerant temperature controller. Make sure that the mark on the flywheel is located in front of the notch installed on the clutch housing cover. To prevent the crankshaft from turning when unscrewing the screws securing the accessory drive shaft, you will need the help of a friend. The assistant needs to sit behind the wheel and engage fifth gear while holding the brake pedal. At this time, use a 17mm socket to remove the screw securing the drive pulley. Dismantle this unit.
4. Remove the washer. To ensure that the further assembly procedure does not cause difficulties, we recommend fixing the camshaft pulleys relative to each other; this will require a wooden wedge. It must be carefully, effortlessly driven between the teeth of the shafts. The wedge itself should be placed along the grain of the wood.
5. Using a 15mm wrench, loosen the screw securing the tensioner. As a result of these actions, the roller will rotate, which will weaken the tensioner.
6. Remove the worn belt from the camshafts. Remove the product from the coolant pump pulleys as well as the crankshaft. Remove the strap from the engine compartment. Remember that after dismantling the product, it is not allowed to rotate the crankshaft and camshaft over long distances, otherwise this will lead to contact of the valves with the pistons, as a result of which the former may bend.
7. When changing the strap, the support and tension roller of the product are also replaced. To do this, unscrew the screw securing the device and remove it with the thrust washer. Using a 15 mm wrench, unscrew the bolts that secure the support element; it is removed from the seat with a screw and washer. Assess the operating condition of the pumping device. There should be no traces of refrigerant leakage on the mechanism body. If the pump is working, then its shaft rotates freely and without any extraneous sounds or jamming. Otherwise you need to replace it.
8. Before installing new rollers, a special sealant must be applied to the threads of the screws that secure them. The bolt of the support device must be tightened to a torque of 34-41 Nm, but the tensioner does not need to be fully tightened. Before installing the belt, make sure that the camshaft marks match the marks located on the rear drive cover. With the disk of auxiliary elements removed, you can independently adjust the position of the crankshaft by aligning marks 1 on the toothed pulley and marks 2 on the oil pump device.
9. Install a new belt on the crankshaft. Pull the product, placing one part of it behind the support roller and the other behind the tension roller. After this, the strap can be put on the camshaft pulleys. If, as a result of dismantling, you used a tool to fasten the pulleys, then at this stage it must be dismantled.
10. The final step is to adjust the tension of the product. To do this, use pliers to turn the tensioner counterclockwise. This action is performed until the first cutout on the outside of the device cage is aligned with the second cutout on the inner sleeve. Use a 15mm wrench to tighten the screw. If you have a torque wrench, then tensioning should be done taking into account a torque of 20-25 Nm. After installation, the crankshaft must be turned by the screw securing the pulley several turns. The node must be moved clockwise. Make sure that the marks on the crankshaft and camshafts match during installation. If any devices, including the pump, pump and other components, need to be replaced, it is better to do this during the repair.

1. Dismantle the timing belt protective cover

2. Install cylinder 1 according to the marks

3. Unscrew the tensioning devices with a wrench

4. The tension of the rollers is carried out with a special key

Tension check

How to check the correct tension of the strap after replacing it yourself:

1. Make sure the marks are aligned correctly and tighten the tension roller if necessary.
2. The tension diagnostic procedure must be performed in the middle between the camshaft discs. If a load weighing 10 kg is placed on this place, then the product should bend no more than 5.5 mm.
3. If the belt is overtightened, then when you start the engine you will hear a noise uncharacteristic of its operation. Operating the product in such conditions significantly reduces the service life of the strap, as well as bearing devices.

What should be included

When the time comes to replace the timing belt in the Lada Priora, many owners invariably face problems related to the fact that they do not know which spare parts still need to be replaced. The presence of two camshafts in the timing drive mechanism has lengthened the toothed belt, so in addition to the tension roller, a support device is also installed. The bearings of the support and tension rollers are designed for a long period of operation, but experts recommend replacing them.

Kits are available for sale that contain a toothed belt and rollers, support and guide. Often the cause of problems with the drive is the pump, which sometimes jams while the engine is running. In this case, the valves in the cylinder head and the piston are damaged. Therefore, it is advisable to purchase a replacement cooling pump, as well as antifreeze or antifreeze for topping up.

If the engine has a “solid” mileage, the camshaft and crankshaft gears will have wear, so they also need to be replaced. If they are not replaced, the teeth will be damaged. If engine oil gets into the working area of ​​the timing mechanism drive, it is deadly, so oil seals on the shafts (distribution, crankshaft) that have lost their elasticity may need to be replaced.

Alternative manufacturers

Not all vehicle owners can choose the right spare part for their car. This is due to the wide variety of products, including timing belts. The main supplier of rubber products for VAZ cars is the RTI plant in Balakovo. In addition to this, sellers can offer buyers Bosch products, which have high quality workmanship and reliability. Also on display you can see products from the companies Daiko, Kontitek, Lynx. Their cost ranges from 700 to 1500 rubles.

Reviews

Sergey. Moscow city. I decided to tidy up the timing drive mechanism on my Priora. Experts suggested trying a product from Contitech. I don’t know why they chose this belt, but it has been working for more than 30 thousand km without any complaints.

Nikolai. Tambov. On the engine of my car, the timing belt broke and two valves were bent. The engine was repaired by specialists who chose a belt from Bosch. After a run of 10 thousand km, we checked the condition and tension in the timing drive, there were no comments.

Hello!! Auto Priora 2008. The tension roller is whistling, the mileage is 39,880 thousand. It needs to be changed, which is better? As far as I understand, there are no alternatives in stores. Which rollers should I look for separately for good ones, install a set of Gates rollers and a belt + also change the pump?

On the Gates website I downloaded a PDF file on how to distinguish a fake, on the Kalinovod forum there is also such a document somewhere. Here it is - https://www.gates.com/Russia/downloads/download_common.cfm?file=70505_E14_ANTI_COUNTERFEITING_BROCHURE_RUSSIA.pdf&folder=brochure I wrote everything down and went shopping. It’s difficult to find Gates kits in stores; they sell belts separately -

I found the videos, completely unidentified without packaging. They seem to be similar to Gates, I didn’t really look at these ones either -

I found 2 stores where they sell these kits, in both they are the same, the boxes are closed with an iridescent sticker with the inscription Original. They cost 3820 rubles everywhere.

The roller there is somehow not impressive with the Gates engraving and, moreover, it doesn’t say 21126-1006238, although it spins silently and is easy to understand. —

The belt seemed kind of dead and thin, but according to the Gates website it didn’t seem to be scorched, although instead of Germany it says Made in UK.

Unlike the one installed on the car, it is clear what it is made of, unlike the factory one, the cord is visible from the side.

But the factory rollers and belt that I have, as you can see, the roller has already shifted and the stubborn one is all splashed with grease. I'm afraid to drive. —

here Gates is engraved with better quality and there is an inscription 21126-1006238

Tell me, who installed the kit I described?? Isn't this a stick? How does it all work? Who installed which company?? I really need it, because the day after tomorrow I agreed to change it at the service center and I already need to know what to buy.

Comparison of Contitech and Gates timing kits

The companies offer approximately the same components. You can install belts from both manufacturers and not worry about breakage. This is true if you buy original spare parts. Fakes can break even after 10-20 thousand km. Therefore, you need to buy any spare parts for your car in reliable stores that sell original products.

Package

Contitech's packaging looks solid and inspires confidence. Each spare part is given a separate box or bag. The Gates kit comes simply in a box with a blister inside. But in both cases, the packaging reliably protects the part. We have not heard of a single case where the belt was damaged during delivery.

Gates has a small advantage - an anti-counterfeit system. There is a code on the packaging that you can use to check the originality of the part on the manufacturer’s official website.

Conclusion : packaging from both manufacturers reliably protects the kit from damage during delivery. Contitech is a little more reliable and solid, but Gates has a code by which you can be sure that you bought the original part.

Tension roller

The Contitech tension roller has a slight modification - additional stiffening ribs that reduce the load on the bearing. There are no other differences. The Gates roller is not criticized for its weak working life, but theoretically, it should last less than the analogue from Contitech.

Conclusion : the Contitech roller has the advantage of additional stiffening ribs.

Idler roller

The rollers from both manufacturers are made with high quality. The parts practically do not differ from each other and will definitely last the 60-90 thousand km allotted to them.

Conclusion : the parts have no significant differences. The working life of the rollers is approximately the same.

Timing belt

The quality and service life of the belts are the same.

On the Internet you can find reviews from car owners who criticize kits from one or another manufacturer. But the details are the same? Yes, the working life of the kits is approximately the same if they are original components.

The dissatisfaction of car enthusiasts is explained by the fact that one day they were unlucky and bought a fake. From this point of view, it is better to install Gates timing belts - they have a code on the packaging by which you can check the originality of the part.

Conclusion : there are no significant differences between the original belts. The parts have approximately the same working life.

So which timing kit is better?

Judging by the reviews of car owners and our work experience, you can safely install kits from both Contitech and Gates. Belts from both manufacturers are quite reliable and will definitely last the stated period.

In general, Contitech kits look a little more solid. They are better packaged, and the tension roller has additional stiffening ribs.

Gates has another advantage - you can check the originality of the part on the manufacturer’s website. Such verification is not necessary if you buy the spare part from a reliable store. But what to do if you have to order a part from a random service, when you have neither the time nor the opportunity to go elsewhere? In this case, you can easily check the spare part using the code on the packaging.

Conclusion : Timing kits from Contitech and Gates are approximately the same in terms of price/quality ratio. You can safely install belts from both manufacturers. Provided that you purchase original components.
