Gates timing belts: reviews. Gates (timing belts): quality, selection tips

In a car engine, every detail is important and requires special attention. The timing belt is one such part. Considering that this rubber product is subjected to colossal loads in harsh temperature conditions and in an aggressive environment, you understand what the quality of production should be. This is why most people prefer Gates timing belts.

This article will discuss the types and differences of Gates products (timing belts), tips for identifying counterfeit products, reviews, applicability and selection tips. And in order to make everything completely clear, a little information about the timing belt itself.

What is a timing belt

The main function of the timing belt, or timing belt, is to synchronize the operation of the engine's crankshaft and camshaft. In diesel units it is also connected to the high pressure fuel pump (HPF). Previously, in engines this role was performed by a chain. Today there is also a significant proportion of cars with chain synchronization. Why did the belt begin to be used in such a critical place in the engine?

To make it clearer, let’s look at the main differences between a belt and a chain in an engine timing belt:

• a timing belt system produces less noise;
• significant reduction in weight compared to a chain;
• reduction in the cost of repairs for components and labor;
• The structure of the timing belt itself is simpler;
• The belt should be replaced at least every 60,000 km under normal conditions. In harsh operating conditions, these periods are even lower.

The timing belt is an important component of the engine in terms of repairability in the event of a break. The consequences of failure of such a belt will, at best, lead to the replacement of part of the valves. In the worst case, all valves, pistons, camshaft and crankshaft will need to be replaced. The responsibility on a rubber product lies simply enormous. Therefore, it is best to replace it regularly and choose among the products of the most responsible manufacturers. And Gates (timing belts and other products) constantly deserves the best reviews.

Resource test

To determine the service life of belts, there are special stands, one of which is located in the laboratory of NPO Talis LLC. This stand completely replicates the geometric arrangement of the units (pulleys and belt tension rollers) that come into contact with the drive belt when operating the engine; more precisely, when creating this stand, standard units were used, which are installed on internal combustion engines produced by VAZ. The stand is universal and provides the ability to install belts that are used for both 8-valve and 16-valve engines of front-wheel drive cars produced by AvtoVAZ. Also, by replacing the pulleys, it becomes possible to test belts with both trapezoidal and semicircular tooth shapes.

The belt is driven by a toothed pulley, which rotates a 7.5 kW electric motor - it acts as a crankshaft, causing all drive units to rotate using the timing belt. The belt is tensioned using the standard timing belt tension roller. The role of the camshaft is performed by an electric brake, which, when braking, creates a resistance of 27.5 N/m - this is a five-fold overload of the force that, during normal operation, is transmitted by the timing belt in an 8-valve engine. Thus, we turn every hour of belt running on the stand into five hours of work on the car.

According to the test method TU 38.1051912 “Toothed belts for VAZ engines,” the belt must have run for at least 100 hours, which turns into 500 hours of run time during normal engine operation. To fully simulate operating conditions, the space in which the timing belt operates is covered with a casing with thermal insulation installed in it, and the working area is heated to a temperature of +90 degrees - this requirement is not found in either the specifications or in any of the test methods known to us, but we decided make the job more difficult for the belt. When braking, the electromagnetic brake converts all incoming rotational energy into heat - and requires cooling, so an autonomous pressure cooling system is organized for the electric brake, which takes up no less space than the stand itself.

Test results

None of the timing belts we tested presented any surprises—all of them honestly worked the required 100 hours on the bench. When inspecting each timing belt after testing, no damage was found that could indicate imminent failure of any of the belts.

Features of Gates timing belts

Gates has a century-long history of development. In 2022, it will be 100 years since the first V-belt rolled off the production line. The company survived such a long period of time for a reason. Just having our own research center speaks volumes. Today it is the largest supplier of belts for cars and agricultural machinery, not only for conveyors, but also for spare parts.

When it comes to timing belts specifically, Gates offers products with strict requirements for quality and reliability. After all, timing belts operate at high speeds over a wide temperature range, while being exposed to oil. So, the features of Gates timing belts include:

• the use of nitrile in a synthetic material with increased wear resistance and protection against oil and aggressive environments;
• the use of fiberglass in the cord, spirally placed inside a rubber shell;
• a variety of tooth profiles that precisely align with the gears and ensure tight grip and silent operation;
• the availability of a variety of repair kits, including not only a tension roller, but also a special tool, and additional spare parts necessary for replacement, for example, pumps;
• good protection of products from counterfeiting.

Characteristics and Features

The Gates company was founded in 1911. In 1917, the V-belt was first produced. Since then, the company has been producing drive belts and hoses for cars. It is one of the largest suppliers of products for conveyors of auto manufacturers around the world, including AvtoVAZ. The quality of the products fully complies with the manufacturer's requirements for the original. The use of the latest technologies makes it possible to create new products with improved characteristics.

Gates Supplies

The following types of belts are produced under the Gates brand:

Wedges. The products have a cross section and transmit force through the side surface. Made from oil and petrol resistant rubber. Non-reinforced belts with molded ribs have a V-shaped profile and have high lateral strength. High-strength polyester cord provides increased flexibility, which makes it possible to use products on small diameter pulleys. Used on passenger cars and small minibuses. For V-belts, reverse bends, which cause tension on the inner surface, are unacceptable. In some cases, multiple belts may need to be installed to provide the required tension and flexibility.

Polycline. Made from several low profile V-belts. Thus, these products have good flexibility and are resistant to both forward and reverse bending. They can withstand heavy loads, so they are used to transmit serious forces. The flexibility and strength of poly V-belts makes it possible to use them on all mounted units, ensuring their rotation. Advantages of these products:

• elasticity;
• strength;
• tensile strength;
• tolerate high temperatures and oil well;
• resistant to abrasive effects;
• reduce vibration;
• help reduce noise.

“MICRO-V” belts facilitate the return of the tensioner and automatically tighten it, while they control auxiliary units in zigzag transmissions.

Variator belts. The cord of these products is made of aramid or polyester, the coating is made of a special compound elastomer or a high-strength fabric base. The innovative components used in manufacturing ensure the operation of the variator in any conditions. The products have the same width along the entire length, which guarantees the necessary inclination of the teeth, ensuring soft running and reliable operation of the variator at high speeds. Aramid fibers and FLEXWEAVE coating provide the following advantages:

• wear resistance;
• flexibility;
• preservation of properties under any operating parameters of the variator;
• resistance to compression and tension;
• high resistance to loads for different driving styles;
• fracture strength;
• good grip;
• durability.

Original variator belt Gates
Timing belts. Designed for a gas distribution mechanism in which it is necessary to synchronize the operation of shafts where rotation occurs over a wide range of speeds. Thanks to the fiberglass cord, the belts have increased elasticity and are resistant to stretching. Durable lining protects against moisture, high temperatures and oils.

Branded timing belt

The improved series of timing belts are made from highly saturated nitrile, they last longer when operating in extreme conditions. Disadvantage - they do not tolerate jerks well. Advantages:

• reduce the load on engine shafts and bearings;
• almost not subject to stretching and vibration;
• do not require lubrication;
• durable;
• help reduce noise:
• Corrosion resistant.

Due to the fact that the teeth are molded with high precision, perfect engagement of the grooves on the sprocket is guaranteed and the noise level is reduced.

The PowerGrip timing gear repair kit includes timing belts and metal parts: tension rollers, support plates. Since modern engines are very demanding on consumables, for reliable operation of the car the belt should be changed along with metal parts. It is necessary to constantly monitor the condition of the products. They should not be allowed to have cracks, bends, unevenness on the outer surface, folds, etc. If any defects are detected, the components should preferably be replaced as a set.

Types of timing belts

Considering that Gates produces timing belts for almost all types of cars, their number in the classification becomes clear. The manufacturer has developed detailed selection catalogs. For your car, you can easily and simply find the right timing belt, its reinforced analogue, as well as an installation kit, if necessary.

For passenger cars, Gates offers belts that are completely identical to their original counterparts:

• normal quality;
• enhanced quality;
• complete with roller or rollers;
• in an extended set with sealing elements and all important timing belt-related components.

In addition to belts with a standard tooth for a particular vehicle, there are varieties with teeth in the form of a trapezoid and complex shapes for different operating conditions.

If we consider the general types of Gates belts, the variety of shapes and models is even brighter. In addition to the standard type, designated Power Grip, there are:

• polyurethane belts;
• bilateral options;
• with conveyor type cord;
• resistant to paints and varnishes;
• open timing belts of all the above types.

Reviews

Reviews of Gates belts will help you make a more competent selection. Thus, by purchasing a high-quality repair kit, you will ensure reliable engine operation for a long time.

Are there any disadvantages?

Positive reviews from Gates, whose timing belts have a long list of advantages, tell us that there are no product shortcomings. Is it really? The biggest disadvantage of products from a well-known and popular company is the large number of people who want to counterfeit them. And when there are negative reviews among the reviews, then with a 90% probability we are talking about counterfeit products.

The manufacturer's extensive experience in protecting products from counterfeiting allows the consumer to receive their Gates timing belt kit or any other product in proper quality. You can read about ways to protect products on the official website, in bulletins distributed with the product, and in this article.

How to distinguish an original Gates from a fake?

The popularity of a well-known company, together with high quality, and therefore good demand, has always attracted those who want to fake the same Gates timing belt. How to distinguish a fake? There are several ways to determine whether it is an original or a counterfeit, and the process of identifying the truth should be approached systematically.

First of all, you need to pay attention to the packaging. Gates takes this issue very seriously. All timing belts are packed in cardboard packaging. If the product is not packaged, it is 100% fake. Only recyclable cardboard is used and the paint is solvent-free. That is, the cardboard should not be covered with a bright glossy picture. Information about the application and article number of the timing belt is made in the form of an adhesive label, and is not printed on the packaging.

The holographic sticker or Holospot from Gates has complex protection in the form of multi-layers, a special code and the actual holographic inscription. Also, the original packaging must contain a sticker to record the mileage at the time of replacement. Counterfeiting a Gates timing belt in such conditions becomes much more difficult.

The next point to pay attention to will be the markings on the belt itself. At the factory, this information is printed in white, hard to erase color. Here, too, there are three points that may indicate counterfeit:

• the country of origin must be specified;
• five-digit number identical throughout the belt;
• the numbers on the right edge of the marking should go up in increasing order.

Price: 800 rubles

The belt is in branded cardboard packaging, on the box there is a sticker with a QR code. The kit includes a sticker that indicates the date of replacement and mileage, as well as which of the components - roller, belt, pump - were replaced. This is convenient: you won’t have to struggle to remember when the last belt replacement was made and what exactly was replaced. In addition to branded and general designations, the belt is marked with a batch number.

The appeal of Gates timing belts

It's time to figure out why the reviews are so good. Gates (timing belts) creates products with many advantages, including:

• high wear resistance;
• production of the entire required period with a reserve in conditions of an aggressive environment and large temperature ranges;
• silent operation, thanks to precise selection of teeth and soft material;
• colossal tensile strength due to the fiberglass in the cord.

Fiberglass, which is used in the cord of timing belts, on the one hand, increases stability and tensile strength. But there is a downside, or rather a disadvantage. Such a belt has an increased risk of breaking during jerking. Therefore, for a car with such a belt, “starting” from a pusher is contraindicated.

Due to the high flow of goods turnover and the release of numerous batches, Gates allows itself to maintain reasonable prices for its products. And a Gates timing belt, the price of which can be 900 rubles, is a common picture on the market. And the product testing and quality control program maintains the brand of a worthy competitor.

Gates Achievements

Among the most popular achievements is the story of the almost century-long production of the first belt, as well as the presence of its own scientific center. The company constantly accumulates information, as well as searches for and resolves issues with the quality and reliability of materials. Thus, developments in the field of rubber products brought Gates to the rubber goods market in the areas of refrigeration and air conditioning systems.

The company successfully patents all its developments and inventions. A consistent approach to the development and implementation of technical solutions has led to the expansion of production to 70 factories around the world. Thousands of jobs and global recognition are what Gates deserves. Almost every 2nd timing belt replacement occurs with Gates products.

Reviews of Gates timing belts

Most users of Gates products express a general opinion of high quality and low price. On the well-known “Otzovik” there was only one opinion about the short service life. At the same time, no one checked whether they were talking about Gates, or whether the person simply came across a fake.

Many people like simple but functional packaging. Others are attracted by the company's huge range of products. What’s interesting is that such a large selection of Gates timing belts for passenger cars represents only a small portion of the company’s total products presented on the world’s markets. A much larger volume falls on belts for agricultural machines and various industries.

The best timing belts in the mid-price segment

This category of automotive products is represented by companies from Europe that have an average cost and have proven themselves well. Such elements are made from cord fabric or cord rubber, and additional substances are added to reduce noise and increase wear resistance.

Bosch - good quality for a reasonable price

In addition to household appliances, the company successfully produces auto parts. They have the best timing belts due to their long service life and relatively low cost.

Applicability of Gates timing belt

In order to occupy the maximum niche in sales, Gates produces timing belts and kits for the entire range of cars, both cars and trucks. Products are supplied to conveyors of such well-known brands as:

• Ford;
• Audi;
• Volkswagen;
• General Motors;
• Chrysler;
• Toyota;
• Nissan;
• Opel;
• Renault;
• Fiat and a number of others.

The popular Scania, MAN, Iveco and, of course, Mercedes-Benz are not left out of attention. Thus, replacing the timing belt with a Gates kit will work like clockwork for models of the above-mentioned car manufacturers.

Complete set of timing belts

Along with just timing belts, Gates offers the consumer options for a comprehensive system replacement, which includes one or more rollers and mounting bolts. This Gates timing repair kit is designated PowerGrip and is packaged, like all products, in an individual box indicating the article number and application. The kit necessarily contains assembly instructions and a sticker to indicate the mileage.

There is also an option for extended timing replacement. Such kits are called PowerGrip Plus and may contain, in addition to the belt and rollers itself, various o-rings and seals required for replacement, and sometimes a water pump assembly. The pump is included in such a kit only if the car manufacturer recommends replacing the timing belt. It is worth noting that the tension roller can be included either as part of the tensioner assembly or separately, again, according to the recommendation of the equipment manufacturer.

A few words about replacing the drive belt

Correction of odometer readings on cars

It was already noted above that the timing belt should be changed every 60,000 kilometers. However, this is far from the only case in which such repairs are required. In addition to the expiration of its service life, belt replacement may be required:

• Or when it breaks. Diagnosing this breakdown is very simple - the car stalled with a short, strong bang from the engine compartment and will no longer start;
• Or when it wears out early. This will require systematic checks, which should preferably be carried out every 15,000 kilometers.

Let's say the need for replacement is confirmed. What should I do next? In a typical case, the procedure is as follows:

1. We remove the belt or its remains from the car structure. If the repair is caused by a broken drive belt, then we also check:
   • valve;

   pistons;

2. all timing elements.

If everything is fine with the listed nodes, consider that you are very lucky and will be able to get off with “easy blood.” Otherwise, eliminate all existing faults;

3. After completing the first step, using the markings on the removed belt or special technical documentation for your car, we determine the brand and dimensions of the drive element. In addition, directly in the store, do not forget to make sure that the teeth of the new timing belt and their frequency correspond to the same parameters of the damaged part.
4. Then, of course, we purchase a belt and replace it.

Installation nuances

Replacing the timing belt on most cars requires different timing. If, for example, Renault Logan recommends changing the belt at 60 thousand km, then for many Volkswagens this period is 120 thousand km. Sometimes the manufacturer limits the service life to a time frame, which also makes sense. Therefore, Gates’ recommendations in this regard do not contradict car manufacturers. Even if a Gates reinforced timing belt with a large margin of safety is used, its maximum service life should not be checked.

In any case, replacing the timing belt is recommended as an assembly with its associated elements, that is, at a minimum, rollers and tensioners. Gates kits always come with replacement instructions. If you follow all the recommendations and have experience or skills, you can easily replace the timing belt.

Do I need to change the pump?

The most common question that owners ask when replacing a timing kit is “Do I need to change the pump?” The answer depends on the engine size.

On engines with a displacement of 1.6, a Russian-made pump from the TZA company is installed from the factory. Its impeller is made of plastic, and the bearing and seal are also not of the best quality. Therefore, when replacing the belt, it is also better to update such a pump. Usually it breaks after 60 thousand kilometers, if you do not replace it along with the belt, you will have to contact the service again.

On 1.8 engines, a pump from the Japanese company GMB is installed from the factory. The part is made of reliable materials, and its working life is more than 100 thousand km. There is no point in changing such a pump before the mileage reaches 100 thousand; it is quite reliable.
