Replacing the generator belt when changing. Generator belt: features and possible repair. When the generator belt replacement is required

The replacement of the belt of the generator is not too complex procedure, so it is even under the power of car owners who have not been controlled by the vehicle. Today we will provide you with the instructions for replacing this unit.

When do you need a replacement of the generator belt?

First you need to make sure that the generator belt really needs to be replaced. Certificate of this can serve as a characteristic whistle appearing during the load on the vehicle electronics, for example, when you turn on the radio or headlights, the indicator on the belt belt may report dashboard. Symptoms appeared? Then replacing the belt is inevitable. It should also be noted that the recommended replacement of the generator belt is carried out between 6,000,000 km - 85,000 km of run, by the way, with the same interval, experts advise to change and.

So, start! First you need to purchase the necessary details and prepare the tool. Open the hood. The generator belt is usually located on the left of the engine. Of course, before the inspection it is necessary to drown the engine, remove the ignition key and disconnect the negative wire from the machine battery.

The visual inspection of the belt will make it possible to make the final solution relating to the need to replace it - if some defects (cracks, breaks) are noticeable, then the belt must be changed, without thinking, because otherwise it can break into the most unexpected moment, and it threatens the destruction, both piston group and valves. The cost of such a repair will cost the owner into a decent amount, and the most terrible consequence of the generator belt break is replacing the engine.

If the traces of wear are not noticeable on the belt, then it will not be superfluous to check its tension, since this is also a fairly frequently found problem.

Remember: Before removing the old generator belt, it is necessary to carefully examine its location and place of attachment, it will help to avoid unnecessary difficulties during the installation of a new belt. For the safety net, maybe even need to draw a draft location of the belt.

Replacing the generator belt do it yourself

We proceed to replace. To remove the defective belt you need to temper its tension. At this stage of work, you need to use the key to remove the nut of the tensioner bolt. Before starting this stage of work, carefully inspect how the tensioner is arranged, it may be, depending on the model of your car, is represented in the form of a rail having a shape of a semicircle or in the form of a stretch bolt.

If the belt tension is regulated by a bolt, then select the key suitable sizeAfter, turn it into one of the parties. Note - this bolt does not need to get out to the end! The belt should relax immediately after the bolt turns. It is necessary to continue this procedure until it is possible to remove the belt without much difficulty.

Now compare the old belt with the new - they must be similar! If the old and new belts are the same and other unforeseen problems in the process did not occur, then we go to the installation of a new belt, it is carried out in reverse order.

Upon completion of the installation of the new belt, we connect the removed terminal to the battery, run the engine and give the maximum load on the electronics - turn far light Headlights (by the way, if they suddenly), air conditioning, radio tape recorder and bring the engine to limit revolutions. If you heard a whistle, it signals that it is necessary to strengthen the belt tension, but do not overdo it! By the way, in the instructions for each car indicate the optimal tension of the generator belt, so do not be lazy to contact it for help.

On this, the procedure for replacing the generator belt is complete, your car is in good condition, now you can easily get behind the wheel and enjoy the trip, not afraid of any problems!

More than anything simplest and effective was not invented, to transfer torque from the crankshaft to the rotor of the generator than the belt. It would seem that the rubber with the polymer threads is special in this piece of rubber? But the gap of this at first glance is a minor element entails not only the impossibility of charging the battery and de-energize the many nodes of the car, but also the possibility of a complete stop of the machine. Since the charge of the battery is mainly designed to start the car, and the functioning of the entire electrical network provides the operation of the generator. To avoid such nuances, you should know the main types of this product, the resource of its service, possible signs indicating its wear, and how the generator belt is replaced with their own hands.

A variety of engines structures led to no less species, drive belts of attachments of attachments and their correct location.

For better contact with knots they are made various shapes The inner surface and are divided into three types:

• gear - products with a variety of transverse profile pitch with high accuracy of the gear ratio;
• polyclinic (streams) with longitudinally located ribs with greater reliability;
• wedge - trapezoidal sections, where the workers are the sides, not intended for the opposite bending.

For each of these species, respectively, manufacturers recommend and lifetime, which can vary within 50-70 thousand kilometers of car run.

Different cars - different installation scheme

In earlier models of the machines, a direct connection of the engine pulley drive was used without any bends, but in a modern car, it is often used belt transmission to supply torque to drive several devices: air conditioner, pump, air conditioner compressor, generator and other units. And running between these nodes belt, can write fancy configurations and bends, this pattern is called - the scheme proper Installation. In a stock car enthusiast, this drawing should always be at hand, so that if you happen on the road, do not suffer, the foreform, remembering how to replace the generator drive belt. Well, naturally, it is advisable to carry a spare kit for every unforeseen case.

Signs indicating belt wear

Before losing the methods and methods of replacement, let us touch the possible signs that indicate that this time approached:

• with an external inspection, when the engine is turned off, the loss of elasticity, cracks, small breaks and splashed sides are observed, explicit sign close failure;
• weakening of the belt tension, due to its stretching or breakdown of the tensioning roller;
• a noticeable whistle when the engine is started, increasing the revolutions or turning on the electrical appliances, the reason may be covered in a bad belt tension or jamming of one of the drives involved in the scheme. This can be both a compressor or generator drive, and the failure of the air conditioner clutch bearing or the tensioning bearing;
• the appearance of the signal on the sensors indicating the decrease in the charging of the battery or the operation of the generator itself.

We should not forget about the planned replacement of this product within its service life.

Options for replacing the generator belt

For work, when the generator belt replacement is required, no special skills and knowledge are needed, it is impossible to call such work simple, but there is nothing superordinary in it. Initially, you should disconnect the mass from the battery, and figure out which parts, protective covers, or other nodes prevent the access to the belt and the generator.

If the generator drive is directly connected to the motor shaft pulley, then everything is very simple here, since in this case the stretch is made by the fastening bolts of the generator itself, plus an additional locking bolt. Freeing the space for free access to the belt and the generator, the above-described bolts are unscrewed, and the belt tension weakens.

Watch the video on the topic:

In another embodiment, where the functioning of not only the generator, but also air conditioning, pumps and other nodes depends on the belt, the work on replacing the generator belt is slightly complicated. May have to take off front wheel Protection of the wing and crankcase to access the belt, the tensioning device and the wires involved the aggregates.

After removing all interfering details, weakening the belt:

• if the tension occurs due to the roller, we weaken the bolt or nut locking roller;
• if this function performs a spring tensioner, the same result is achieved by simply affecting the roller, in the desired direction.

Having removed the belt preferably to hold if his condition causes doubts, then replace it. Also inspected the belt, it is worth paying attention to the nature of damage, and find out why they were formed. Often, the failure of various mechanisms can provoke its wear and gap.

It will be necessary to compare the old and new belt: the length, the width of the teeth (streams), etc. There are precedents of incompassions for some parameters, it would seem that the branded product.

Installing a new belt should be held in the same sequence and on the existing location scheme for a particular car.

The generator in the car produces electricity necessary to charge the battery and the normal operation of the entire on-board car electrician. Immediately after starting the engine, the mechanical energy for rotation of the rotor is transmitted from the engine via the generator belt, the rotor rotates, and the generator starts working. On modern cars, a single drive is often used with a roller system, which besides the generator itself, leads through the system of rollers and tensioners other attachments: POMPU, air conditioner compressor, steering hydraulic power pump, etc. Over time, the generator belt replacement is required, as well as replacing its rollers and tensioner. The deadlines for the replacement are spelled out in the instructions on the car and should be carried out with planned maintenance, but they are very often neglected, especially when the warranty period ended. And naturally, the drive, worked out all the possible time, does not stand the load and breaks.In such cases, we offer services for replacing the generator belt with departure to the breakage. And all car owners recommend pre-acquire in advance and carry a spare drive belt with them. Below on video shows how to change the generator belt.

Immediately make a reservation, not on all models of the car, and not in all cases can be changed drive belts in road conditionsIn such cases we offer to stationary car service.

Dates of replacement of drive belts

As mentioned above, the deadlines for the replacement of parts are written in service book Your car, but there are signs to notice the stretching of the belt: first, when you start the engine, a characteristic unpleasant whistling, disappearing with an increase in engine speed, then such a whistle manifests itself when the engine is working in wet weather.

Everything modern cars Equipped with sensors that signal the generator malfunction (test light with an image of the AKB), but on many models the sensor shows only the fact that the belt is cut or flew.

Therefore, pay attention when the ignition is turned on but!, Before starting the starter, check the battery control light. Sometimes car owners do not pay attention to that this lamp does not burn, especially next to other lamps - this is an important signal of problems with generation of electricity and / or battery charging voltage.

The main reasons for the failure of the generator belt:

• Stretching and breaking due to aging - operational repair and replacement in place of breakage is possible;
• Weakening the belt tensioner (and replacing the rollers of the generator belt) - it is possible to operate operational repair, replacement and tensioner, and rollers on site breakdowns (check with the operator for your car);
• Hitting under the belt of foreign objects (stones, branches) - it is possible to operate and replacing the breakdown in place;
• Damage, inconsistency of pulleys, tensioner rollers, enhancing the generator or any other attached equipment on the same belt, - We offer only the call and repair to a hundred, because Open, stretching or leafs belt - a consequence of mechanical damage to mounted equipment, and the usual replacement will not be able to help - at the start of the engine, the belt again flies or burst. (See the engine drive circuit on the engine)

The diagram shows that besides the generator itself, the belt brings several nodes, passing through the rollers and the tensioner - the water pump, and the hydraulicel, and, accordingly, damage to any of these nodes leads to a break or the actuator track.

The difference between the replacement of the belt of the generator and the replacement of the timing belt

Sometimes car owners confuse the replacement operation: the producer belt and the timing belt (gas distribution mechanism).

Carefully inspect the damaged drive:

• smooth or longitudinal grooves for pulleys and rollers is a generator belt,
• if you see the transverse teeth on it - this is the timing of timing.

Welcome!
This detail links the pulley of the generator with the crankshaft pulley and the pulley of the water pump on the classic models. On the front drive vehicles, the pulley of the pump binds the timing belt. The broken belt of the generator on the classics will cause poorly working devices, because the energy will only go from the battery, respectively, with a bad charge, the instruments will be racing. On the contrary, if the battery is powerful and fairly charged, then for some time the devices will not go out and you can even not notice that the belt broke. And then it is necessary to remember about the pump and pay attention to it, since the belt binds it, it means that the break will lead to the cessation of the circulation of the coolant in the system and the machine will begin to warm much.

Note!
You will need the following tools: a mounting blade (a comfortable thick stick or a small metal scrap) is suitable, wrench will be needed on "on 17" and "at 19".

Location belt

Located in the front of the car. The photo of the red arrow shows the radiator of the cooling system and the bar on which the battery is standing (now removed). The belt connecting the three pulley is indicated in the photo of a blue arrow.

When to change the belt?

The main reason is the wear: various kinds of cracks, worn edges, stared teeth. We do not recommend tightening with the replacement of the belt, otherwise the gap will lead to the overheating of the engine and even boiling during the strong heat. The battery will quickly be discharged in the absence of support from the generator, which will stop spinning and give energy.

Note!
Have you ever had to hear the whistle of the car? The sound gives the timing belt, it arises for various reasons:

• strong wear often leads to a whistle;
• water or any liquid falling on it (for example, the coolant falls on the belt when the cooling system of the cooling system, which give to flow. Recognize the problem will help the inspection of the belt and pulleys for moisture);
• weak belt tension (adjustment will come to the rescue, read below);
• low belt quality, it is a straight oak belt (by the way, it hardens in the frost).

Most cars B. winter time The year is published by a whistle at the Institute of Motor, and the driving machine no longer whistles - a sign of the reinforced belt.

The video below can save you in emergency situation: If the belt suddenly breaks, there is no spare - an ordinary belt or tie will come to the aid! Look in detail in the roller and wind on the mustache, you never know, everyone will come in handy in life.

Removal

Note!
Removing the battery will make it easier to access the belt. The process is described in the article: "Replacing the battery on cars."

Evaluate appearance belt. In the case of a good condition, check the tension, tighten it if necessary. Check easy: Lift your hand strap with an effort of 10 kg in any place. Either the distance "A" distance to which the belt should bended will be 10-15 mm, or in the place "in" 12-17 mm (see picture).

Note!
It is more convenient to stay and check the deflection at the point "A". Any deviation from the norm requires belt suspenders. Remember, do not remove the belt from the pulleys if you are not going to replace!

Move into the lower car and one turnover, screw the bottom nut of the generator (see a small photo), get out of the vehicle from under the car and go to the incaparment. On one or two turns loosen the nut upper fastening The generator (with a red arrow in the photo), will help you the extension with the cardan hinge and the cape head (the tools are shown by the blue arrow). Weaken through the battery installation bar.

Note!
The upper nut, the fastening generator to the bar for all is twisted differently, so you feel that the nut goes easily (you do not turn it out completely), then immediately stop unscrewed!

Go directly to the shift of the belt. Move the generator to the engine and remove the belt. If you just need to adjust, then insert the assembly blade between the engine itself and between the generator itself (see the photo below), and, using the shovel as a lever, shift the generator from the engine. Holding the shovel in this position, tighten the top nut fastening the generator to the bar and the bottom too. Release the blade and remove it, check the belt tension and, if necessary, do the operation again (in the event that the tension does not fit the norm).

Installation

At the beginning, the belt is installed on the crankshaft pulley. In the image above, see the pulley is specified by the number 3, the pulley of the generator number 2 and the pulley of the digit pump 1. To the end, slide the generator to the engine, if it is shifted, but the belt is still not installed, then neatly scroll through the pump pulley (upper), or in the extreme Case Ask the assistant to take advantage of the crooked starter scrolled a little pulley, and at this time you put the belt to the top pulley of the pump.

The generator set is the main element in the electrical network of any car. It is necessary to immediately eliminate its malfunction. Below we will talk about replacing the Ford Ford Focus Generator belt 2 on its own.

Why do you need to change the belt on time?

The generator strap in Ford Fox cars 100, 105, 115, 125 restyling and dorestayling, according to official data, marked in the technical book, should change every 60 thousand km of run. When violating the timing of the periodicity of replacement, the belt can be broken, which will deliver the inconvenience of the car owner. The service life of the strap can be shorter, everything is due to the terms of use, the correctness of the installation and the quality of the part.

The need to change the product can be understood by the presence of defects and other damage on the structure itself. If the generator strap breaks, all equipment will be powered directly from the battery. With proper functioning, the electrical appliances receive voltage from the generator set, which also restores the battery charge spent on the engine start. In the event of a cliff, the battery strap will not be able to resume the container, which will lead to its rapid category and the impossibility of riding a car.

Also installed drive strap is used to ensure proper operation of the hydraulic power amplifier Ford Focus. If a break occurs, the GUR will turn off, and the driver will have to make efforts to turn the steering wheel.

Signs of emergency replacement

The fact that the strap will soon fail, can report the appearance of a whistle. In crude weather, the whistle appears when the machine's motor starts and disappears over time. If the belt is worn, then it will not shift, especially when the electrical appliances and other equipment are turned on, for example, optics. In some cases, the battery of the battery appears on the control panel of the car. This may be associated with both problems in the battery and the generator faults.

Other "Symptoms" Wear Products:

• the appearance of cracks on outside strap;
• the product was strongly stretched, it lost elasticity;
• appearance of supervisors on the structure of the strap;
• formation of damage on the inside;
• the structure of the belt began to settle.

Detail Selection Settings

When selecting the strap, it is necessary to consider that the goods purchased must correspond to the length and size of the worn item. IN Ford Focus The straps are used, the size of which ranges from 705 to 975 mm. Here you need to rely on the year of the vehicle, its version and model. To find out to know about how the belt is used in your car, you can technical manual. Models Focus 2 equipped with a 1.4-1.6 liter motor and air conditioning system can use products: original Ford production, German confectione belts, Italian dike or bosh. The last manufacturer is considered the most popular among consumers.

If machines with the same motor without air conditioning, it is desirable to use the straps of original manufacture, as well as manufacturers of Gate and Contitate. Dyko, Contitate and original details Allowed to use in models of focus 2 equipped with aggregates by 1.8 or 2 liters. Similar belts can be installed in restyled vehicles. Also, products listed manufacturers are allowed to use in machines equipped with diesel engines.

User Pavel Meshshkov provided the instructions for replacing the drive generator belt with his own hands.

Step-by-step instruction

Replace, wear and tighten the product yourself.

Required tools

We change the belt after all the tools are collected:

• set of wrenches;
• dressup device;
• tensioner;
• screwdriver Set;
• jack;
• videos.

A fitting device can be purchased in the store, rent a service station or develop a drawing and make it yourself. The tool for putting on will make it faster to perform the installation procedure, and the rollers will be required provided that the old parts have begun to wear out.

The user Ernest told how the generator strap independently produce.

Stages of replacement

To correctly remove, put and pull the strap of the generator installation and air conditioner, you must act according to such a scheme:

1. Replacing the ford generator belt focus is performed from dismantling the product. To do this, remove the key from the ignition lock of the car and open the hood. Unscrew the screws fixing the terminals connected to rechargeable battery, then dismantle them.
2. Loosen the screws that fasten the front right wheel. Put this part of the car on the jack. Screw the screws completely, and remove the wheel.
3. After dismantling the wheel, you can remove the liner. Disconnect and remove in the direction of the mudguard. Having access to the generator strap, make it removed. To do this, use a pre-prepared knife. After cutting and disassembling the belt, clean the surface of the shaft.
4. Rate visually the state of the installed rollers. If there are defects, the details are subject to replacement.
5. Now you need to install new belt And make a stretch. The strap should be positioned in the center between the pump hydraulic amplifier and crankshaft. You will see the pump wheel, the tool for installing the part is mounted on it. When the tool is installed, it should be checked counterclockwise.
6. It is necessary to wear a strap on the drive pulley. It is mounted in such a way that the number located on the surface is directed towards the machine motor. The installation of the belt on the shafts of the hydraulic amplifier, the air conditioning and generator system are performed.
7. The product tension is performed. The key to 19 is to rotate the pulley of the water pump. The procedure is performed carefully. While the pulley spins, the strap is stretched. Scrolling is carried out before the moment until the belt stretches and will not sit full on the pulley. Take a wrench to 18, with if you check crankshaft For several revolutions. As a result, you can check the correct installation of the part.
8. To stretch the edge of the Condera compressor drive, put the fixture device for mounting devices. Installation is carried out in such a way that the tool is between the pulley axes. The device is placed on the device and install on the compressor shaft.
9. The crankshaft turns again. It is done until the time the product does not completely sit on all the shafts. If you managed to do this, then the installation for mounting is removed, and the crankshaft is scrolled by 2-3 turns. Check if all actions are performed correctly and evaluate the quality of the product tension. With an insufficient or too strong stretch, fast wear strap is possible. After mounting, make sure that the product grooves are properly installed on the shafts on the shaft. Otherwise, the strap can squeeze when starting the engine, which will also lead to its wear and cliff.
10. Collect everything in the reverse order. Replace the scene and the wheel, securely tighten the bolts. Get the motor and check the belt operation correctly. At first, he can make noise uncharacteristic for its operation. Subsequently, the sounds will disappear when the belt will come true. You can use special tool for softening, sold at any store with automotive chemistry. With the help of it get rid of outsided sounds.
