Alternator belt size for VAZ 21214 injector

About the belt

All belts are different; the Niva 2121 uses a V-belt, while more modern Nivas such as Urban and Chevrolet use a poly-V-belt. The poly V-belt has a larger contact patch and is more resistant to wear.

The length of the belt depends on the number of attachments; if the car has air conditioning or power steering, the belt will be significantly longer than in a Niva without additional options.

Transferring the generator to the top 21214 drawing

Niva is an excellent domestic SUV that can compete with modern jeeps. VAZ 21214 received a durable body, a powerful power plant and a reliable suspension. Like any car it has its drawbacks. These include the location of the generator - the unit is installed in the lower part of the body. When testing for strength in forest and mountainous areas, dirt, sand, and water get into it. Another unpleasant point is that coolant constantly drips onto the unit. The problem can be solved by moving the generator upstairs.

After reading this article, you will learn:

• What is needed to move the generator upstairs. How does the process work for cars with and without power steering? Is it worth buying a new unit for VAZ 21214.

Study this drawing carefully. The author decided to make a bracket for moving the generator with his own hands. The part is made of metal, the thickness of which should be 4 mm, and the width and length should be 80 mm. To assemble the bracket, you will need parts from other domestic cars:

• Belt 6РК1290; Adjustment bar; Crankshaft pulley from tens.

Photo, details of the manufactured bracket 21214:

As you can see in the photo, the standard fan is installed on a pump pulley from GAZ 3110, we also take a crankshaft pin from 2110 and a 6RK1290 brand belt. The generator should be located on the top left side. It must be attached to the top using an M8 cylinder head bolt; at the front, a standard bolt and studs are used. For fixation, the bracket must be secured with an additional lock nut.

This generator transfer drawing differs from the first one in that it uses a belt with a size of 1375 mm. There are fewer steps here, but you will have to work with a grinder - you need to reduce the plane on the head located in the area of ​​the M8 bolt.

The front cover will need new bolts and studs. This drawing of a bracket for mounting a generator is also suitable for other models, for example, for 21213.

The drawing suggests moving the generator to the place of the hydraulic booster. To do this, you need to make a bracket and install it next to the power steering. You need to select washers for the bracket ears in advance.

This option uses a belt with a size of 1220 mm

It is important that the angle of its wedge must be exactly 40 degrees. An excellent solution would be to buy a belt with ZIL 157

The return hose has a center length of 1115 millimeters, and the high-pressure pressure hoses are 1450 mm. Check all dimensions carefully, remember the saying: measure 7 times, cut once, there is no need for mistakes here. There is no standard hole for these hoses in the right casing, so you will have to take it and cut it yourself.

The bracket itself for moving the device upstairs is made according to this drawing:

The pump must be turned upside down so that the generator is completely seated. The result of the transfer looks like this:

If you don’t have much experience in carrying out such upgrades, then you can buy a ready-made kit. It will include a new bracket for the Niva and the necessary fastenings. Reviews from motorists indicate that the cost of this simple part is too high.

Should I install a more powerful current generation unit?

We have already described above why the unit wears out quickly. An excellent solution is to install a new generator. Another common reason is the installation of off-site equipment that consumes a lot of electricity. The current strength of a standard unit is not always enough, so you should think about installing a more powerful generator.

The model depends on the year of manufacture of the car and engine. For example, the first Nivas with a 1.6 power plant have a device with a remote regulator, which was used in the “classics”. In more modern machines the regulator is already built-in.

If you want to buy an aftermarket unit, it would be wise to get a 2003 model year Chevrolet. The selection must be made according to the catalog numbers and parameters that are present in this table:

If you can modify the fastenings yourself, then the list of available gHepaTopoBs can expand significantly. Craftsmen even install devices from foreign cars.

In any case, you should strive to modernize and improve your car. And this applies not only to electricity. The Niva is a reliable SUV, but it lags far behind its foreign competitors in terms of comfort. You can move on to this issue immediately after improving the technical component of the car.

Alternator belt Niva 2121 (carburetor)

The belt in such a field is slightly longer than in a field with an injector and power steering due to the fact that the belt drive also rotates the cooling fan with a pump. In the injection Niva, the cooling fan starts automatically.

Adjusting the tension and replacing the VAZ-21213, -21214 coolant pump drive belt

We check the belt tension by its deflection between the drive pulleys.

1. With normal belt tension, its deflection under the influence of a force of 98 N (10 kgf) between the pump pulleys and the generator should be 10-15 mm

2 or 12–17 mm between the pump and crankshaft pulleys. We adjust the belt tension by moving the generator (with its mounting nuts loosened): from the engine to increase the tension or to the engine to decrease the tension.

3. To replace the belt, loosen the nut securing the generator to the tensioner rod with head “17” on the carburetor engine.

head 4 or “13” - on the injection. We move the generator to the cylinder block to loosen the belt tension.

5. Move the generator, acting on it with a screwdriver as a lever in the groove of the tension bar:

on a carburetor engine;

6 on a VAZ-21214 engine.

Install the belt in reverse order. We check the crankshaft two turns clockwise and check the belt tension. Excessive belt tension causes increased load on the generator and pump bearings.

In this car, the generator drive also rotates the power steering pump.

Troubleshooting

During the operation of any car, unpleasant situations often arise in the form of failure of one or another element. Niva is no exception, and most often the generator suffers.

If the generator seems to be faulty, it is recommended to check its functionality using a multimeter. To do this, you will need to start the engine and check the voltage at the battery terminals. The standard value that a multimeter should read is 13.6 V.

If the readings during measurement are higher, it means that a break or short circuit in the windings has occurred in the structure. The same can be said about the case when the voltage is below the specified number. This procedure is carried out regardless of the engine: injector or carburetor.

Also, if the breakdown is caused by another reason, you can replace the generator itself. Usually, for replacement, they turn to special service stations, but if necessary, the work can be done with your own hands.

Next, it’s worth considering what the owner of a car with a whistling alternator drive belt should do. It is recommended to immediately inspect the mechanism and find out whether it is possible to continue moving or whether it is necessary to immediately begin repairs. Diagnostics is performed as follows:

Open the hood, remove the plastic protective cover from the engine (if it is in the way) and carefully inspect the belt drive for water or process fluid. It happens that the drive gets wet after driving through deep puddles. If oily liquid is found, not only on the belt, but also on the cylinder block, try to find its source

Carefully inspect the pump, power steering pump and air conditioning compressor - all units located next to the drive. When inspecting, pay attention to the engine gaskets so that oil does not leak from under them. Make sure that the belt is not cracked and that there are no threads on the sides. Check the tension using the vehicle's operating instructions. A universal method is to rotate the free section of the belt around the longitudinal axis

The tension is considered satisfactory when the element rotates no more than 90°.

If none of the above methods brings results, you will have to look deeper - loosen the drive belt and remove it from the pulleys. Then try rotating each pulley by hand, the goal is to detect any sticking in the shaft that is causing the belt drive to slip. If everything is in order here, carefully examine the working side of the strap - the “licked” surface will make it clear that you received a low-quality product.

Niva Urban generator belt

Niva Urban is a more modern modification of the Niva with plastic bumpers. A poly V-belt is used here as a generator drive.

It should also be noted that if the Niva Urban is not equipped with air conditioning, then it uses a regular V-belt from the previous Lada 4x4 model.

Installed a new Chinese generator on Shevik

How did they even manage to tighten the 1885 belt? I can't imagine))

First I'll tell you about the generator

I took the old one, they completely disassembled it, looked at it and said that it had come to an end. The bearings were torn, and the rotor was worn out to such an extent that repairs would cost 2,500 rubles. And a new one costs 3100. It’s Chinese, but the warranty is 3 months, we checked it at the stand - everything works.

Therefore, it is better to take a native gene with the same width of the roller and with the correct number of rivulets (grooves). That’s why the belt is called a ripple belt, because the grooves must match, it turns out something like rails.

I wanted to buy a 100 Amp Pramo, but I couldn’t find it anywhere in the city; the original genes cost 4,000 rubles. So I decided to try Chinese))

First you need to loosen the belt, which if tense, cannot be easily reset. So, our task is to loosen the tension roller; it is held in place by a platform with three nuts. You will need a 10mm wrench, it is very advisable to have a ratchet with the same head, preferably an elongated one, because the third nut is located directly under the belt and it is better to approach it from the side.

The first 2 nuts are easy to get out with a regular open-end wrench. But the third one is much easier with a ratchet.

We've loosened it - now we turn the adjusting screw (key 10) so that it moves as far up the platform as possible, so the entire platform with the roller will move freely up and down.

We need to go up to throw off the belt.

We remove the generator itself (in my case, I already put it back)

Niva Chevrolet

This car is significantly different from the classic Niva, therefore. and its components are completely different. In the Chevy Niva, the air conditioning compressor is driven by a separate belt. The alternator belt rotates the power steering, alternator and pump. Due to the large amount of equipment, the belt length is quite long.

Niva Chevrolet air conditioner belt dimensions

The air conditioner belt is a poly-V belt with the marking 4PK810, from here you can calculate its length as 810mm.

Generator replacement

To repair or replace the generator, the car owner will have to remove the unit completely from the car or turn to professionals for work. If you still want to carry out the replacement yourself, then first you will need to prepare all the necessary tools:

• hammer;
• extension;
• keys to "10" and "19".

The procedure consists of the following sequence of actions:

• First, you will need to park the car in a place designated for inspection and repair. The car will also need to be secured using special wheel chocks. Finally, in order for the work to be carried out safely, you should disconnect the battery by disconnecting the terminals from it.
• After this, you need to remove the engine protection. It is attached to several bolts, and they must be unscrewed to get to the lowest bolt of the generator.
• After this, you will need to knock out the mounting bolt using a hammer. It is recommended to knock carefully so as not to damage the thread and to prevent the bolt from coming out in the opposite direction. A hammer is necessary, since a wrench or any other tool simply cannot handle a bolt.

• Next, you need to remove the bolt, swinging the generator from side to side. It is necessary to bolt in any case, as this makes it easier to remove the rod.
• The fourth step involves disconnecting the wiring. To do this, the power wires connected to the housing are disconnected from the unit. In this case, you can first disconnect the plug from the wires.

Wires are also attached to the generator, tightened with a nut or bracket. In this case, the nuts must be unscrewed with a wrench, and then the loose wires must be pulled out.

Finally, after disconnecting the wires, you can begin to unscrew the upper fastening element with the belt tensioner. For this you will also need a wrench, as well as a small extension cord.

Disconnecting the fastener will allow you to remove the belt and alternator. Then you can start cleaning the vacated space with a brush and installing a new unit.

The structure is assembled in the reverse order; the entire procedure will take about two hours if you have all the necessary tools.

Additionally, it is worth noting that when everything is assembled, you will need to adjust the position of the generator using the tensioner. To do this, you need to unscrew the tensioner nut and tighten or loosen the belt, while observing the battery charge.

If the indicator returns to normal, then the selected tension is sufficient. There is no need to tighten the structure, as the generator bearing may fail. If the tension is insufficient, the generator will work intermittently, and this can also lead to breakdown.
