Replacing the rear springs of a VAZ 2107 with springs from a Niva

The VAZ 2101 fuel pump rod is the main part of the membrane drive.
Now we will talk about what the VAZ 2101 fuel pump rod is, and what problems it can cause for the driver of the car. If you have not yet come across such a detail, then be sure to read it, a lot of interesting things will be told. Moreover, this is worth reading not only for owners of kopecks, but also for nines and tens, with carburetor engines.

The principle of driving the fuel pump is the same for all. And all the breakdowns, accordingly, are also the same, despite the obvious differences between the cars. Of course, the reliability of engines of eights, nines and tens is higher, but the rod still tends to wear out. Let's start with what a fuel pump on a VAZ 2101 is, and how it pumps fuel through itself.

Design features of the fuel pump

On VAZ 2107 cars with a carburetor system, fuel pumps of a mechanical operating principle are installed. This product is located directly in the engine compartment on the side of the cylinder block.

The main structural elements of the fuel pump are the elements shown in the diagram.

The operating principle of the product is based on the movements of the pusher. Such movements occur due to the functioning of the fuel pump drive cam and the return mechanism. When the working membranes move, pressure and vacuum are created in the product chamber. When the pressure decreases, the exhaust valve closes and gasoline is supplied through the fuel line and the opening inlet valve. When the pressure rises, the intake valve closes, causing gasoline to flow through the exhaust valve, which leads to the carburetor. Through the inlet and outlet valves, gasoline is pumped from the tank and supplied to the carburetor.

Signs of fuel pump defects

The main types of fuel pump malfunction, which indicate a breakdown of the mechanism, are the following:

• inability to start the engine;
• when starting, the engine starts and stalls;
• the engine cannot reach full power.
• After some time after starting to move, the car stalls and stops starting. The reason for this on a carburetor seven may be overheating of the fuel pump. When overheating occurs, the intake and exhaust valves become misaligned, which leads to asymmetrical operation. To quickly cool it, owners of Soviet cars put a damp cloth on the product, after which they can continue driving.

These are the main signs indicating the need to diagnose the fuel pump. The presence of these factors leads to the fact that owners of the “Seven” and other cars of the Lada family think that the malfunction lies precisely in the fuel transfer device. To check the product for serviceability without removing it from the car, you need to perform the following steps:

1. Loosen the hose that supplies gasoline to the carburetor, and then remove it.
2. Plug the hose using an M8 bolt.
3. After this, you should pump the device’s manual drive lever. If gasoline flows out of the outlet fitting in a stream, this indicates that the device is working properly.
4. After this, you should also loosen the second clamp, then remove the hose and plug it.
5. The inlet fitting must be plugged with a finger, and then the lever must be pumped several times. If there is a noticeable vacuum, we can say that the problem does not lie in the pump. If there is no vacuum, that is, the finger is not attracted to the fitting, then the pump must be repaired.

The pump creates appropriate pressure in the system, which will be absent if it breaks down. In order to repair the fuel pump, you will need to purchase a repair kit. But sometimes the causes of product malfunction are elements that are not included in the repair kit, so the device needs to be replaced.

Symptoms indicating a faulty pump and rod

A fairly common cause of product failure is an element such as a rod. This is a steel shaft that was hardened back in the Soviet years, and now no one wants to spend money on this process in order to produce a part that costs 30 rubles. This is now called unprofitable, so modern parts wear out very quickly, as a result of which their length decreases.

It is important to know! If there is a gasket under the product body, you can remove it, which will allow you to lengthen the rod structure.

The main symptom of rod wear is the inability to accelerate the VAZ 2107 to the required speed. To do this, you need to drive out of town and then press the accelerator pedal. If the car accelerates, but at the same time, having picked up speed to a certain value, does not develop it, then the reason is precisely the worn-out fuel pump rod.

Replacing the fuel pump rod

In order to replace the rod on the fuel pump, you need to unscrew the 2 fastening nuts using a 13mm wrench, after which you need to remove the product. A new rod is being installed on a VAZ 2107.

It is important to know! Not many people know what a fuel pump rod is, but this is the main part of the membrane drive. It is through the rod that the pump operates.

After installation, it is necessary to adjust the rod, for which, using a ruler, you need to measure the protrusion of the device beyond the spacer. This protrusion should not be more than 1.3 cm, and also not less than 0.8 cm. After removing the pump, you can measure the old rod; if its length is less than 0.8 cm, then the part must be replaced. Once the fuel pump is set up correctly, the engine will function like a clock.

Before installing a new rod, it is recommended to harden it by holding it under a blowtorch until the part turns red, and then dip it in water.

In conclusion, it should be noted that even such a small part can cause inoperability or poor engine performance. Fix the problem and then evaluate the effect.

When to change?

Let me refer to quotes from the forums: look at how your lower control arm is relative to the ground, measure the distance from the edge of the wheel to the arch, and the like. Of course, there is some truth in all this, BUT these are all consequences. We need to look at the reason, that is, at the spring itself. The next legitimate question is: where to look? The photo shows springs from the same car, one side before replacing the springs, the other after.

when to change springs?

For some reason I remembered the magazine “Murzilka” with pictures on the topic, find 10 differences)). Red circles indicate where to look. Why do springs in this condition need to be changed and why is this criminal? Different alloys have different physical characteristics. In particular, spring steels do not withstand shock loads at all. When the coils of the springs close to full contact, an impact occurs. Stress tends to accumulate, and at some point the spring bursts. If this happens at low speed, the face of the car will simply fall down. The fuse will be the shock absorber, which will bend, and if the swing was stronger, then the body will lie on the wheel. It is much worse if this happens at speed or somewhere on the descent from a hill. I saw a short video from the Ladoga Trophy, when a short Niva drives down a hill, bounces a little and turns over. What can be seen in the slow motion replay: when flying up, the suspension dissolves. Then, the face of the car goes down, the spring bursts, the body falls on the wheel... and the car does a somersault through this wheel, since the kinetic energy has not gone away.

Fuel pump functions

The fuel pump is an essential component of the power supply system of any engine. The correct start and stability of the motor depends on how stable the device operates. As is correct, carburetor Zhigulis are equipped with DAAZ 2101 diaphragm-type mechanisms. This is a fairly simple device in terms of design features that can be easily repaired at home. On the other hand, it has to be repaired often.

The job of the fuel pump is to supply gasoline to the carburetor.

As mentioned above, the design of the mechanism is imperfect, which leads to frequent problems. The fact is that most often the quality of fuel at our gas stations leaves much to be desired. And the pump constantly works under high load. Gradually, problems with the fuel pump occur, which leads to unstable operation of the power unit.

Springs Kilen-Lesjofors, coating

I cannot help but note the issue of spring coating. The most important difference from other manufacturers is not the paint. Primary coating is made with zinc phosphate, secondary with epoxy powder. Let me note an important thing. Spring coating isn't just about "beauty" - it's about long-lasting performance. Metal whose structure has been penetrated by rust is, in most cases, scrap metal. In St. Petersburg conditions, the coating lasted more than 7 years before the first chips appeared on the springs.

Suspension springs have a direct impact on the smoothness of the car and driving safety. Being in constant operation, these suspension elements wear out, and therefore they should be regularly inspected for mechanical damage. It is also necessary to constantly “listen” to the behavior of the car when hitting bumps.

The main signs that it is time to change the front springs on a Chevrolet Niva are:

• Reduced ride smoothness, suspension breakdowns;
• Creaking, grinding and a characteristic metallic knock when hitting an uneven surface;
• Distortion of the front of the car;
• Noticeable “sag” of the front suspension;
• Body sway when driving, etc.

How to independently diagnose the fuel pump on a VAZ 2107

You can check the performance of the fuel pump yourself without resorting to the help of specialists. To do this, follow these steps:

1. Loosen the clamp and remove the hose leading gasoline to the carburetor. There is some gasoline left in the pipe. So be careful not to get dirty. It’s better to place a small container and drain.

2. Using a special lever we pump up gasoline.

3. If gasoline flows from the fitting, then the pump is working. If not, follow the next steps.
4. Remove the pipe from the pump supply fitting.

5. We place a finger at the inlet of the supply fitting and try to pump up the pump. If your finger is sucked in, then the device is working well. If not, you need to disassemble it and look for the cause of the problem.

Fuel pump drive repair

The fuel pump on the seven works using an eccentric and a rod according to the following principle:

— the “pig” (intermediate shaft) rotates under the influence of the timing chain;

— the eccentric presses on the rod;

— the rod presses the pump lever, forcing it to work.

The weak point in this system is the rod. Today it is made from very bad metal. Therefore, the rod can wear out within the first thousand kilometers of use. Its edge is wrinkled. Naturally, the part in this case must be replaced.

Signs of breakdown

Among the obvious breakdowns, the presence of which may require replacing the VAZ-2106 fuel pump, one can highlight one - a leak. If the housing is constantly wet, covered with gasoline that drips onto the engine block, it is necessary to carefully inspect the unit and make repairs. It is quite possible that the seal was lost due to loose tightening of the fastening screws. In this case, you don’t even have to disassemble the entire assembly, but wipe it dry and tighten the bolts with a screwdriver. If desired, you can change the engraving washers. If a leak appears from cracks in the housing, then it is better to completely replace the VAZ-2106 fuel pump. The price of a new one is not very high, but the resource is quite decent.

The next two malfunctions, typical of mechanical pumps, are diaphragm rupture and valve failure. If the membrane is torn, gasoline will begin to flow into the lower chamber of the fuel pump. And the unit will stop creating pressure in the system. There are two valves in the top cover - inlet and outlet. If one of them stops working normally, the necessary pressure will also not be created in the system. Very often the valves stick when exposed to high heat. In this case, you can moisten a rag with water and place it on the pump body - this is the only effective way out of this situation.

Replacing diaphragms and valves

To replace these elements, you need to perform a few simple manipulations:

1. Hold the diaphragm rod by the shank.
2. Unscrew the nut.
3. Remove all components of the diaphragm assembly. Be sure to remember how they are located.
4. Reassemble in reverse order. The holes for the bolts must match. The tongues should be directed in one direction.
5. Next you will need to remove the valves from the seats. First you need to open them with a needle file.
6. Be sure to cap it after installing a new valve.

Purpose

Chevrolet Niva comes from the factory with springs, both front and rear. The main purpose of these devices is to absorb all the shocks of the suspension that occur when the wheels hit potholes and bumps. They are located in the gap between the wheel and the frame of the car, due to which shocks from the road are smoothed out.

For their manufacture, special high-strength steel is used. The number of turns of the device affects not only the quality of shock absorption, but also the distance of the body from the suspension.

Many Chevrolet Niva owners upgrade the rear springs by installing spacers or reinforced parts.

Repair of fuel pump VAZ 2107

You don't need many tools to remove the device. It will be enough to prepare a screwdriver and a key crosswise at 13 millimeters.

Dismantling is carried out in the following sequence:

1. We wipe the fuel pump so as not to get dirty.
2. Remove both clamps and pipes.

3. Now, using a wrench or socket, unscrew the two fastening nuts and remove the pump.

Now you can safely disassemble the mechanism:

1. Unscrew the cover bolt

2. Remove the cover and take out the filter

3. Unscrew all six bolts connecting the two parts of the pump

4. Now we have the opportunity to separate parts of the device body

5. Let's continue the analysis. To do this, rotate the diaphragm 90 degrees and remove the spring.

6. Unscrew the nut

7. We completely disassemble the assembly and carefully inspect all components for wear.

8. Filters need to be cleaned and worn parts replaced.

Good afternoon everyone! I decided to raise my car for the winter and delved into numerous articles on this matter, and then I realized that there are a million opinions, and perhaps this entry is being read by someone who has encountered the same problem - what to install?

I wanted to raise it to stock or to Niva, I hesitated, delved into Drive2 and the entire Internet. There are many options and conflicting opinions, I want to write my opinion, maybe it will help someone.

After a week of searching for information and tips, I settled on this option:

Front struts - Niva Rear struts - Ordinary classic (in my case Hola oil) Springs all around Niva. (Class A or B, I don’t know, it wasn’t written).
