Engine belts are a simple and effective means of transmitting the rotation generated by the engine to the auxiliary mechanisms of cars. One belt can drive several units at once. Car belts drive generators, water pumps, power steering pumps, air conditioning compressors, radiator fans, coolant pumps and other mechanisms. During operation, it is necessary to regularly check the condition and tension of the drive belts. In order to avoid engine damage, you need to replace generator belt and other drive belts in accordance with the vehicle operating instructions.
Automotive belts are divided into several main types - wide, normal-section drive belts and fan belts. Each belt for air conditioning, alternator and other components is selected depending on the type of car model. Wrapped straps are used to protect the side parts from wear and provide integrity to the entire structure. Cotton and nylon are used as outer covering. Toothed threaded belts transmit forces using the transverse teeth of the belt and the drive mechanism; they are able to maintain a given position of the shafts. When used, such belts do not need to be lubricated; they practically do not stretch or vibrate.
The Rincom company offers a range of components and spare parts for automobiles, including automotive V-belts and poly-V-belts. The company's catalog presents belts for various engines: domestic and imported, cars, trucks, tractors, combines.

Tell me where to find the alternator belt, but it’s a couple of centimeters longer, so it turned out that mine broke and I threw it away without checking the size. the gene adjustment bolt was at the very bottom, when I started installing a regular VAZ belt, it didn’t fit. I can’t move it to the maximum, one part of the gene rests against the engine
I remind you that the usual 938, and the Volgovsky 1025 is very long

I created this topic because I often do modifications to my machine. The installation of the alternator made it clear that the original belt was too long, and the Moskvich belt, on the contrary, was short. I had to take an old belt and run to several stores. I found something, but forgot the size (I'll see when I get to the car). Maybe someone has access to belt catalogs or there is another practice. Let's drop here verified information about the sizes of mono-V belts that are on sale. Information on which car this belt is installed on is also desirable.

Wheels for VAZ 2107
Despite the fact that the model was produced for many years, and it would seem that the restyled versions should have been very different over time, the wheelbase, body shape and other external parameters remained unchanged.
The wheels on the VAZ 2107 in the factory configuration have the following parameters:
VAZ 2107
- Standard drilling for VAZ products, or the diameter of the hole on the car axle shaft, which is 58.5 mm, as well as a bolt pattern, each hub is attached to 4 studs of 98 mm each. This is a fairly universal size, since many European wheel manufacturers, which are installed on most economy cars, often use the 4.x100 size, which is fully compatible with the products of the Russian plant.
- For the last 30 years, the concern has been exhibiting its cars in the simplest configuration with classic rims in size 5J. × 13 ET29 in a stamped design and without caps, which can easily accommodate 165/80 / R13 and 175/70 / R13 tires.
- More expensive modifications were equipped with 5.5J wheels. × 12 ET32 and tires 175/65/R14 or 185/60/R14, slightly increasing the disc offset so that the visible part of the wheel does not protrude beyond the transverse dimensions of the body.
- Wheels 15 for 2107. A special highlight of the early years models. All these years, the plant has been installing wheels with 6J parameters on top trim levels. × 15 ET25 and, accordingly, tires 185/55/R15 or 195/50/R15, and this was the maximum that Russian engineers managed to achieve.

Drive belt: types, faults, markings.
Malfunctions of poly-V-belts of attachments and methods for their elimination
Operational wear is inherent in any structural element, and moving parts exposed to friction and under load are more susceptible to wear than others.
Belt damage poses a high risk of an accident. The main safety measures are monitoring the condition of the belt and timely restoration of its functionality (cleaning, tightening, etc.).
- An unpleasant sound (squeaking) while driving indicates a weakening of the belt tension. In this case, it is necessary to perform a tightening without delay.
- If dirt and traces of fuels and lubricants are found on the belt or pulleys, the system requires cleaning.
- When inspecting, pay attention to the appearance of the drive belt - the presence of mechanical damage (frayed belts, tears, worn edges, etc.).
To ensure trouble-free operation of the system and extend the service life of the poly V-belt, it is also important to monitor the auxiliary devices, primarily the idler and tension rollers. They directly affect the driving behavior, the degree of wear and the likelihood of damage to the belt, and therefore must be kept in good condition.
The rollers are constantly under pressure and wear out as a result. Roller wear affects the degree of belt tension and the quality of the system as a whole. The drive belt, pulleys and rollers are checked at least every 15 thousand km. mileage The rollers are replaced when significant wear is detected and when the suspension belt is replaced.
Checking the drive belt
Evidence of irregularities in the operation of the poly-V-belt is not only a whistle, but also other extraneous noises occurring in the engine compartment. These sounds clearly indicate that the likelihood of the belt breaking has increased significantly.
This gap, in turn, can lead to much more serious problems, the most minor of which is the lack of light.
Rules for replacing a poly V-belt
The drive belt must be replaced:
- in case of a break or significant damage is detected indicating a high probability of break,
- after 50 thousand km. mileage since the start of operation or since the previous replacement.
When replacing a belt, it is recommended to follow certain rules:
- Before installing a new belt, it is carefully inspected for defects.
- When replacing a belt, the roller system is also changed along with it.
- The belt tension should ensure a deflection of no more than 5 mm.
Accurate and correct installation of the belt that transmits torque from the engine ensures the correct operation of a number of systems, since the flexible design of the poly-V-belt allows you to assemble a vehicle generator and a whole range of auxiliary equipment into a single system.
The performance of each element of this system directly depends on the operating parameters of the drive belt:
- no sagging,
- no vibration,
- motion trajectory accuracy,
- uniformity of movement.
Checking the belt system, its rollers and associated pulleys is mandatory during any vehicle inspection.
If the drive belt is cracked (consequences)
If your car's drive belt(s) are worn out, they will have cracks and scuffs on the surface. As a result, a whistle will begin to appear as they move. In this case, the time has come for their planned replacement. Remember that if you do not change the drive belt on time, you risk being left without functional vehicle equipment. For example, if a belt has reached the end of its service life due to severe wear and tear, it will naturally break sooner or later.
Typically, when the drive belt breaks, you will hear a loud bang from under the hood. As a result, the equipment that received torque from it will cease to function. For example, if the drive belt powering the alternator breaks, it will stop charging the battery and powering all electrical equipment in the car. You will eventually see the battery icon illuminated on your dashboard.
Also, if the belt breaks, the power steering will stop working. As a result, your steering wheel will become very difficult to turn. But the most important problem when the drive belt breaks is the lack of rotation transmission to the water pump, which promotes the circulation of coolant through the engine cooling system. As a result, the engine can quickly overheat. In this case, you must immediately stop driving and turn off the engine.
Therefore, while driving, constantly monitor the engine temperature sensor, which should show the same temperature of 90 degrees after the engine warms up. If you see that the temperature needle has gone up and is approaching the dangerous red zone, then you need to stop and, turning off the engine, diagnose the cooling system.
Attention! Overheating of the engine can lead to its failure (damage to valve stem seals, failure of the head gasket, damage to the piston system). Therefore, do not allow the power unit to overheat under any circumstances by monitoring the engine temperature on the dashboard.
What determines the service life of drive belts?
Modern drive belts have a fairly long service life due to their construction from modern, reliable materials. On average, a quality belt can last up to 25,000 hours of operation. Please note that service life is shown in hours, not kilometers, as mileage does not directly affect the service life of drive belts. After all, these belts are in motion even when the car is standing still and the engine is idling.
But this is in theory, and according to information provided by belt manufacturers to consumers.
In practice, the service life of drive belts may differ significantly from that declared by the manufacturer. The fact is that the wear of drive belts is influenced by many factors. For example, the way it was installed on the car plays an important role in the long service life of the belts. For example, it is not uncommon for car mechanics in technical centers, due to their low classification or lack of experience in car repair, to try to fit a belt onto a pulley using a screwdriver. As a result, the new belt is damaged and will no longer be able to serve the period stated by the manufacturer. This method of installing the drive belt is also used to speed up the replacement process without removing the pulley.
In addition, the service life of the belts is affected by the storage conditions of the components in the warehouse and their transportation. For example, it is not uncommon for car dealerships to sell drive belts that have expired. Yes, drive belts have an expiration date. The fact is that the chemical composition of drive belt materials changes over time. And if the drive belt was manufactured 5 years ago and was stored incorrectly in the warehouse, then when installed on the car it will not last very long.
Weather can also affect the durability of car belts. For example, if you live in a hot climate, then you often use air conditioning. This means that the air conditioning compressor must receive more energy. As a result, the belt transmitting torque to the air conditioning compressor experiences increased load.
Drive belts can also wear out quickly if the machine is operated for a long time in cold weather. For example, in winter, the electrical equipment of the car requires more power than in warm weather.
As a result, the alternator requires more power to maintain the vehicle's electrical system. As a result, the alternator belt experiences increased load due to increased torque.
As a rule, drive belts in a new car last longer because they were installed at the factory and all necessary storage conditions were observed before installation. After replacing the factory drive belts, the life of the belts will be reduced.
Each car manufacturer usually indicates in its technical documentation and service book during routine maintenance when it is necessary to routinely replace drive belts. Therefore, we advise you to carefully read the list of scheduled technical inspections and the schedule for replacing consumables. As a rule, the manufacturer indicates the maximum mileage at which technicians at the technical center must replace the drive belts. This way you will know approximately the service life of the drive belts. But this does not mean that you should not regularly inspect the condition of the belts.
How to tension, tighten or loosen a drive belt
If the cause of the whistle, squeal or squeak is a belt that has become loose, causing it to slip on the pulleys, then if the belt does not show signs of wear or damage, in order to remove the extraneous sound, it is necessary to tighten the belt.
Using the generator belt as an example, this is done using a special adjusting bolt (on modern cars) or using an adjusting bar (on older cars).
For example, to tighten the alternator belt on a modern car, you need to do the following:
— Loosen the generator mounting bolts slightly (upper and lower fastenings)
— Turn the adjusting bolt clockwise, moving the generator away from the engine block and immediately checking the belt tension level
— Then shade the nuts of the generator fastening elements
Please note that in some vehicle systems, the process of tensioning the drive belts is too labor-intensive and requires the use of special tools.
Attention . A new generation of poly-V-ribbed elastic belts are currently widespread on the market and in many cars. For example, one of the world's well-known manufacturers of such belts is the Elast company. Their products have proven themselves to be the best. This company is the official supplier of many car factories. Elastic poly V-belts do not require tensioning, tightening, etc. Thanks to their design and material, such belts do not stretch. Typically, such drive belts last about 120,000 kilometers.
But for its initial tension a special tool is required.
Many cars also use special belt tension rollers, which saves drivers from constantly tightening belts. The only drawback of this design is that, as a rule, when replacing drive belts, it is also necessary to change the tension roller, since its reuse together with a new belt is impossible.
How can I temporarily replace drive belts if my car breaks down on the highway?
Unfortunately, it is not possible to temporarily replace drive belts with something if they break on the highway in modern cars. In older cars, women's tights sometimes helped with a similar problem. But those times are gone. If the drive belts break, you will need technical assistance.
Wheels for VAZ 2107
Car wheels perform more than just basic operational functions. It’s hard to imagine the stylish appearance of a car without well-maintained and attractive wheels. When choosing a product to install tires on, a number of factors must be taken into account.
Decisions about tuning should never be made at the expense of the technical characteristics of the car. The selection of wheels for the VAZ-2107 will be successful if you take into account a number of technological and design features of the model.
Throughout the entire period of serial production, the VAZ 2107 was equipped with stamped wheels with a diameter of 13 inches (R13) for standard 175 // 70 R13 tires. Export versions, as an exception, were equipped with light alloy models of the same size.
In addition to diameter, car wheels have a number of other parameters:
- width;
- bolt drawing;
- departure;
- centering hole.
The nominal width of the VAZ-2107 rim of different models ranges from 5 to 5.5 inches. This size is important for the vehicle's stability; The coefficient of adhesion to the road surface depends on it. Symbol 5.0J or 5.5J.
The bolt design in production models is indicated by the symbols 4x98, where 4. is the number of holes for fastening the bolts, 98. is the diameter in millimeters of the circle on which they are located. Simply put, 98 mm. this is the distance between the central axes of opposite holes. Novice motorists underestimate another important parameter. The diameter of the hole affects the reliability of fastening the wheel to the hub; this must be taken into account when choosing fastening bolts.
Departure. this is the distance between the plane of contact of the disk with the hub and the plane that conventionally cuts the rim in the center. There are positive and negative overhangs. In the first case, the wheel is recessed into the arch, in the second it is shifted to the outer limit or even protrudes beyond it. The nominal offset of VAZ-2107 wheels is positive and amounts to 29 mm (ET29).
What non-standard sizes can be supplied?
Some car owners practice installing wheels with a diameter different from the standard one.
For example, installing 16-inch wheels on vehicles with wheel arches for 14-inch tires may cause:
- damage to the paintwork of the body;
- breakdown of plastic inserts on wheel arches;
- failure of drilling valves.
After installation, non-standard wheels should not touch body parts or wheel arches. This will not only damage the plastic and paint. But this can also cause other problems. Constant friction of the tire against the wheel arch cap leads to rapid grinding of the tread. This requires premature tire replacement.
When choosing custom tires, consider the following points:
- low-profile tires improve car handling, but when driving on roads with poor-quality surfaces, the likelihood of damage to the suspension increases significantly;
- a larger profile may simply not fit into the arch and damage the car body;
- non-standard profile height requires adjustment, adjustment of the speedometer, otherwise the data it displays will be incorrect.
To install wheels of larger diameter, in some cases it will be necessary to expand the wheel arches with a special roller. This will enlarge the holes and the new wheel will no longer rub the plastic fender liner protection.
How to find out the length of a V-belt
V-belts are special rubber products. These are intermediate connecting elements, the purpose of which is to facilitate the transfer of moment of force from one shaft to another. Due to reliable adhesion to the pulleys, the belts have excellent traction capacity. These transmitting elements are installed on agricultural and industrial equipment, machines and units.
There are several different types of belt drives. The most common of which are considered parallel, where the shafts rotate in one direction. However, there are also cross and semi-cross, which are used to achieve reverse rotation.
Since several such belt elements are usually used in one transmission, the workload can vary in different values as needed.
The cross-section of V-belts is trapezoidal, with their sides being working.
Quite often, premature failures of such elements occur due to the incorrect choice of V-belt length and its profile. And if there are no particular difficulties with the last parameter, then determining the length is a difficult task for many. Therefore, before buying a V-belt, you need to perform this operation correctly by measuring a couple of product values: height and base.
You can find out the belt length and profile using a tape measure, but it is important to remember that neither the internal nor the external lengths of the belts allow you to determine its compliance with the pulley. This can be determined based on the width by which the length values were identified.
So, first you need to place the belt on the pulleys, pulling it well and turning it. Then the distance between the centers of the pulleys is measured. The length value is further determined by the formula: “belt length” * “distance between * “pulley diameter”.
Now, to make a choice, you can compare the obtained dimensions with the table values given below for each type of belt, where the profile is indicated in the left column, and the dimensions in millimeters in the right column.
V-belts of the classic type with shaped teeth and open side edges are installed in devices with increased torque capacity. Their design feature helps convert tensile force into longitudinal force, and a good fit helps avoid rapid wear by reducing the load. They are characterized by resistance to oils and fuel liquids, and performance is ensured at temperatures from minus 30 to plus 60 degrees Celsius.

Wide-angle belts made of polyurethane, in order to promote smooth running, are usually installed in cars with increased power, where the number of revolutions exceeds 15 thousand per minute. The constituent base of the material allows them to be used in conditions with aggressive chemicals. In addition, such products have a long service life and can operate at temperatures from minus 55 to plus 85 degrees Celsius.

Double-sided belts, due to their concave sidewall and vaulted surface design, are considered very reliable, since such features allow uniform contact with the pulley to be achieved and tearing is avoided. Also, this type of product is not afraid of deformation and shock loads.
Disk options
When choosing wheels for the VAZ 2107, consider strength, balancing and size
wheels The main parameters that you pay attention to when purchasing. these are radius and width. The manufacturer equipped the car with standard wheels marked 5Jx13H2 ET29. The numbers and letters indicate the following:
- “five” is the rim width in inches;
- “.” profile;
- “13” rim diameter, inches;
- “H2” is the number of irregularities on the wheel rim;
- “ET” letter designation of wheel rim offset;
- “29” rim offset, mm.
The actual disk settings are as follows:
- The number of holes and the circle diameter on the wheels (bolt pattern) is 4x98 mm.
- The diameter of the sleeve is 58.5 mm.
- Rim diameter 13-15”.
- Wheel offset 15-30 mm.
- Recommended width is 5.0-6.0”.
- Mount M12x1.25.
It’s better not to install wider “Seven” rims. For them you need to choose the right tires. They are larger than the fender liners and can touch or rub against the vehicle's structural components.
Consequences of installing wide disks:
- Rapid contamination of the side of the machine.
- When the wheels turn, they rub against the fenders of the board and body, which leads to severe wear and tear on the car.
- While driving, the tires may touch the brakes, which can lead to an accident on the road.
- Increased wear on the wheel bearings as they will bear a greater load.
Discs with a small rim protrusion (the disc will stick out more from the car) are also not installed. In this case, the hub bearing takes on most of the load, so it can quickly fail or jam.
Wheels are divided into forged, stamped and cast. In “Seven”, stamped steel wheels are installed by the manufacturer. They have an average safety margin, are inexpensive and have a long service life. The disadvantage of the tool is the need for periodic rust treatment, which leads to a rapid loss of appearance.

We will pay special attention to the drawing of the 4x98 bolt. The rim has 4 holes for the mounting bolts that secure it. The diameter of the circle with holes is 98 mm. The distance between the centers of two closely spaced supports for the VAZ 2107 is 69.3 mm. The discs used on foreign cars have a pattern for a 4x100 bolt, the distance between centers is 70.7 mm. When installing such imported equipment on a VAZ, an error of 1.4 mm appears, which is why the disk does not fix and quickly fails. Therefore, car owners use spikes, extended bolts, spacers and cams as fasteners. Incorrect installation leads to imbalance and vibration, loss of the wheel and subsequent accident.
The best options are the R13, R14 and R15 wheels recommended by the manufacturer. They can also be installed on all classic VAZ models starting from 2101.

Review of the best summer and winter tires
It's a good idea to buy two sets of tires. For winter it is better to buy studded ones. Michelin Latitude Sport 3 is a good option for summer. It has good stability regardless of the quality of the road surface and makes it easier to overcome even heavy mud.
Nokian Hakka Black has a relatively high cost. However, compared to others, it performs well in the long term. Even with heavy driving it can easily withstand more than 5 years.
General Altimax Sport. A relatively inexpensive option for use in the warmer months. Even at high speeds this tire model is practically inaudible. Allows you to easily move at speeds up to 190 km/h.
FULDA KRISTALL MONTERO 3 has an unusual appearance. The deep tread and the presence of a large number of longitudinal grooves allow you to move through puddles at high speed. Hydroplaning is excluded.
PREMIORRI SOLAZO. This is a tire that allows you to move without problems even in difficult road conditions. The low weight of the tire saves fuel.
The choice of winter tires should be taken more seriously. With a limited budget KAMA 505 Irbis. good decision. The protector deteriorates quickly. However, this point is fully justified by the low cost of the model. Positioned as all-season.

What types of snow blower belts are there?
To create snowblowers, gear parts are used. In terms of reliability, they are in no way inferior to chains, at the same time they are much more convenient to use and have less weight. Spare parts of this type perfectly transmit the rotational element to the shafts and are easy to fix in a small space.
Quite often, a gasoline snow blower and snow blowers of other types differ in that wedge strands with a cross section and a trapezoidal profile are placed there. They perform many functions, so it is impossible to do without its use when creating equipment.
