Advice 1: How do you set the timing belt on the Audi

Failure of the timing belt can lead to costly engine repairs, especially the Audi. Very important when replacing the belt properly expose all of the labels, otherwise the car just won't start.
How do you set the timing belt on the Audi
You will need
  • A set of mechanical keys
Instruction
1
After you remove the old belt tensioner, put a new idler pulley and secure it with the nut. Previously under the nut and put a small washer.
2
When mounting the bracket, pay attention to her slit he got the tubular peg on the roller. Secure the bracket with the bolt, but not until the end, and then the prongs inside, put on new belt tensioner. Be careful in this process was not shifted to the shafts.
3
Rotate counterclockwise the idler pulley to slightly pull the belt tensioner.
4
Scroll through the crankshaft and look at the label of the flywheel. There should be a label matching the O|T on the intermediate shaft, the camshaft and on the plastic cover. If labels do not match, you must repeat all actions, starting with having to remove the strap and to wear it again.
5
If the labels match, then pull one arm up stock tensioner and rotate the other arm of the tension pulley. Crank it counter-clockwise arrow. Lock design a large bolt, which you are already attach earlier.
6
Then again scroll through the crankshaft and see if it matches the label On|T on the intermediate shaft, the camshaft and on the plastic cover. The coincidence of the labels put on the bottom cover of the timing belt by screwing the two bolts from the bottom, one to the left and one bolt that is centered in the recess and shaped nut.
7
Attach the pulley, screwing the 4 bolts that attach it to the back. Then look at the gear of the camshaft, the mark Of o|T must coincide with the same marking on the plastic boot that covers the upper rear part of toothed wheel of the camshaft. Clockwise rotate the crankshaft until the match mark "0" with the edges of the window in the clutch housing and a sleek arrow that is located on the lower cover of the timing belt over the crankshaft. Match the labels to be sure that the belt timing setting and adjusted correctly.

Advice 2: How to change the timing belt for VAZ

Belt tensioner (belt tensioner) is a closed rubber belt, on the inner side of which is slotted. Its purpose is to synchronize the camshaft and the crankshaft of the engine. For the car VAZ 2109 a resource of this belt is around 100 thousand km mileage. If the belt is worn or damaged, you should replace it before the deadline.
The process of replacing the timing belt for VAZ 2109
You will need
  • VAZ 2108-09, key 10, the key cap or head 19, the socket or head 17, a screwdriver, a portable lamp, a couple of bolts or nails 4 mm thick, in order to tension a new belt, a new timing belt.
Instruction
1
In order to remove the timing belt, you must remove all that can become a hindrance; it will provide maximum freedom for the withdrawal. Most likely, it will hinder the air filter, probably the steering power-steering pump and both pulleys V-belt.
2
Dismantling protection plastic timing belt is done by loosening the three mounting bolts.
3
After that, the crankshaft should be placed in the position of the upper dead point of the piston of the first cylinder. This is done by the slow rotation of a cranked shaft for a bolt to the pulley until mark on the pulley does not dock with the pointer on the rear cover camshaft actuator.
4
After fixation of the shaft with a screwdriver from turning, Unscrew the fixing bolt of crankshaft pulley.
5
Before removing the old belt it is worth noting the direction of his movement and only then loosen and remove. With a weakened belt pulley to rotate the crankshaft not.
6
Disconnect the pulley from the crankshaft.
7
To loosen the belt tension, you need not fully remove the nuts that secure the idler pulley and it rotated.
8
Now the timing belt can be removed.
9
If there is a need with the belt removed, rotate the camshaft, you need to ensure that at TDC, none of the pistons are not located. Otherwise damage the shaft and pistons.
10
Now you can gear on the crankshaft pulley to put the new belt on.
11
On the crankshaft pulley leading the belt is tensioned so that it does not SAG. The label on the back cover and the pulley should be the same.
12
Then the belt is put on the tension roller and a cogwheel of the water pump.
13
Putting the crankshaft pulley, the bolt that it is attached, is clamped 99-110 torque N•m (9,9-11,0 kgf•m).
14
Expanding according to the roller, pull the strap and tighten the nut which it is attached. In the absence of a special wrench to tension the belt, you can use two metal shaft, bolts or nails. They are inserted into holes of the roller between them is assigned with a screwdriver, with which the roller rotates, thus pulling the belt.
15
If the belt is tensioned correctly, it can rotate 90° with two fingers. Scrolling the crankshaft two turns, you need more time to check the tension and convergence of all labels. If necessary, adjustments.
Note
To bend or twist the timing belt is not worth it. Dirt and oil significantly reduces the service life of the belt.
Useful advice
Checking and adjusting tension of timing belt should be carried out on the cooled down engine.

Advice 3: Produces Audi

The car brand Audi is known throughout the world. Their distinctive feature - high quality and recognizable design. The popularity of the brand has forced the leadership to expand the geography of production, today, Audi released not only in Germany.
Produces Audi
Today, the world-renowned manufacturer has at its disposal seven major plants located in Europe and Asia. Head office is located in the city of Ingolstadt, which also produce cars. Another 6 plants located in Germany (Neckarsulm), Hungary (Gyor), Slovakia (Bratislava), Belgium (Brussel) China (Changchun), India (Aurangabad).

Ingolstadt



Here, close to Munich, the main production is concentrated: every day is available for 800 Audi A3 same A4 and about 2 hundreds of Audi TT. Also produce models A3 and Q5. In addition to these cars the plant produces kits to send to China (Changchun, FAW-VW) and India (Aurangabad).

The plant occupies a territory of almost 2 million hectares. in Addition to the parent enterprise, office, a production tool, a marketing Department, Technocentre. The latter is considered one of the best in the world, thanks to the aerodynamic position of being able to "reach" the speed of 320 km/h and lower the temperature to minus 60oC. Installing free use of the members of the Corporation – Wolksvagen, Seat. For others wanting a set fee of 3000 Euro per hour.

High level of technical equipment of different Assembly plant. The degree of automation approaching 100%. Only at the end of conveyor is used the human verification: staff check the quality of the build after the robots and eliminate possible flaws. Every minute the Assembly line is truly Golden: emergency stop for this period will cost 13,000 euros. However, the management of the company is not a supporter of the sweatshop system and attentive to work. For example, when it became clear that the position of the body on the Assembly line at 45 degrees is bad for the spine, was immediately reconstructed Assembly line, and now cars are arranged horizontally.

European plants and Russia



In the German city of Neckarsulm produce A4, A5, A6-A8, R8, Cabriolet and kits for the Indians and Chinese. The Hungarian subsidiary produces (meaning Assembly) of the A3 Cabriolet, TT Roadster, TT Coupe, RS 3 Sportback, and is also engaged in manufacturing engines. Belgian producers are busy with the release of A3, and since 2010 – A1. Q7 is produced in Bratislava.

In Russia has started production of the Audi in Kaluga (based on the WV), but soon he turned. Now the issue of the resumption of production models A6-A8, Q5 and Audi Q7.

Advice 4: How to set timing marks on 2109

For gasoline engines of VAZ 2109 is set the same the timing mechanism and injection. Small differences exist only in the pulleys of a drive of the generator.
The marks on the camshaft
No matter which engine is installed on the VAZ 2109, the composition of the timing mechanism remains the same. However, there is a difference in the pulleys of a drive of the generator. In the injection engine has a wide multi-strap, and wedge-shaped carburetor. But these details are not relevant to the timing, as functions naturally have no effect. The pulley has teeth that required for the engine speed sender. To remove the belt and wear it correctly, you only need to follow a certain sequence of actions.

Removing the timing belt



So first open the hood and disconnect the negative terminal from the battery. In the process, will have to move the generator, you can accidentally hurt his insights and close to ground. After raising the right side of the car on a Jack and remove the wheel. Without removing the wheels will not work to remove the timing belt. On the right side remove the protection, it is fastened with screws to the body. Just put the crankshaft on the label that is on the flywheel. You can see it by removing the rubber cover on the clutch unit.

Now loosen the nut fixing the generator and pull it closer to the engine to make it easier to remove the alternator belt. When loosened it can be removed and see if it cracks and damage. If any, it is best to replace it. No matter multi-strap you have, or wedge-shaped. And now the hardest part – removing the pulley from the crankshaft.

On gasoline engines installed pulleys that have a long window. They can put a chisel or a wrench to Balk in the engine block. A socket wrench 19 to loosen the bolt. But the injection is more difficult, since there are no such Windows. Will have to remove the rubber cover on the clutch unit. In the observation window to set the chisel or large flat screwdriver rest it in the teeth of the crown.

When I removed the pulley, you can begin to removing the belt. To do this, loosen the tension pulley, remove the belt from the pulley on the camshaft, and then at the crank. All, now that you got rid of it, you are ready to install. Try to change the pump, pulley and timing belt together.

Install the timing belt



For starters, you need to set crankshaft and camshafts on labels. As already mentioned, the crankshaft is placed at the mark on the flywheel. After removing the cover, you will see a metal bar with a cutout. This cut must coincide with the line on the flywheel housing.

After embarking on a camshaft. On the engine compartment side, is a plank. But on the pulley there is a mark, which must clearly coincide with that strap on the engine. At the same time evaluate the condition of the pulleys, if they develop. If there is excessive wear, you need to replace them.

Take the new roller installed and najavljen nut. Now put a new belt. First, on the crankshaft pulley, and then, by slightly pulling on the crankshaft pulley. Also wear on the pump and the roller. When I put the belt, a special key we stretch it with a roller. The optimal stretch is when the right part of the belt with little effort rotated 90 degrees. The belt is tensioned, the replacement is over.

Advice 5: Broke timing belt, what could be the consequences

Breakage of the timing belt. What could be worse for the motorist? Except that the subsequent repair of the cylinder head. But on some engines the pistons with recesses for the valves. And for this reason, the breakage of the timing belt is not a terrible motor.
The piston vases with recesses for the valves
Engine timing is the heart of modern motor. It depends on the accuracy of opening and closing of engine valves. On the classics, for example, to drive the camshaft, which is responsible for the operation of the valves, used a metal chain. Very reliable but very noisy. So today, instead using a flexible toothed belt.

Its reliability is also high, but need to monitor this parameter as tension. If it is excessive, the belt could not withstand the load and break. And it is fraught with consequences, sometimes not very pleasant.

Classic and the first Samara



So, the classics were installed on the engines with a chain drive. But there is a engine VAZ 2105, which has the chain replaced with a belt. This is the first motor with a timing belt installed on the classics. Quieter, better comfort, and when the belt breaks the valves are not bend, because the designers have provided all the pistons and made recesses for the valves. When you open the belt transmission, the valves don't slap the pistons, all ends happily.

But the engine 2105 was forgotten and got a bad reputation because of careless masters, making repairs, put the pistons without notches. And following broken belt ended the repair of the cylinder head. To replace the classics came eight and nine, which were installed on the engines with a volume of 1.1 l, 1.3 l, 1.5 L. these engines, 8-valve, broken timing belt without consequences for cylinder head complete only on the engine capacity of 1.5 liters.

The tenth family and the new model



When the tenth family began to put engines of 1.5 liters with 16 valves, there is a risk that the valves can bend when breakage of the timing belt. This could happen for the reason that there is no scoring on the pistons. But the 16-valve engine volume of 1.6 liters has recesses for the valves on the pistons. And it not bend valves if the belt suddenly breaks. And you only need to put a new belt and calmly continue driving.

As for the priors and Viburnum, the first engine is a 1.6 valves will bend, but to break the strap very hard. In width it is almost two times wider than the belt on the engine VAZ 2112. Therefore, the resource it is also higher. And Kalina with the engine of 1.4 liters in case of breakage of the timing belt will probably need to repair the cylinder head.

So, the conclusion is clear that at high belt wear or factory second possible breakage. And it is fraught with expensive repairs to the cylinder head. The way out is to prevent breakage of the belt. And if you specifically, need only time to change the consumables, not wait until the last. Cylinder head repair will cost ten times the price of the belt and the rollers.

Advice 6: How to replace the timing belt on a Renault Megan"

Replacing the timing belt should be made not less than 60 thousand kilometers. A long drive without replacing fraught with belt breakage and repair of cylinder head.
The timing belt on Renault Megane
The timing belt needs to be replaced every 40-60 thousand miles. This is the optimum life span, longer to exploit the already unsafe. Excessive belt wear can occur cliff, which will result in the valves are bent. When the camshafts lose the connection with the crankshaft, there is a lowering of valves, they all are open.

The pistons also still continue to move by inertia, with the result that the force hit the valves. This is despite the fact that the metal of which the valve has a very high strength. To get rid of such effects can be made on the surface of the piston recess. They should be clearly under the flaps to breakage of the timing belt the pistons didn't hit valves. Breakage can also result in the emergence of micro-cracks on the cylinder head. As a result, the engine operation will be unstable.

What you need to replace the timing belt



First, you will need the timing belt. Look carefully to the new belt was not damaged. A small cut on its surface is a sure sign that the life he will not be big. Along with the strap need to replace the tensioner and idler rollers. Do not confuse them places, put the first compartment side and the second side of the radiator of the cooling system. Also need to replace camshaft plugs. Ideally, replacement of the pump of the cooling system.

Otherwise, it may cause leaks and backlash, again you have disassembly and repair. Better if you carry out all the work at once, don't delay for the future. You'll need a small set of tools. Keys and screwdrivers – is itself, in addition to these necessary restraints shafts (camshaft and crankshaft). If there is no such tool, you can make it yourself. Person who understand the principle of operation of such latch, it will be under the force.

How to replace the timing belt



Raise the Jack on the right side of the car and remove the wheel. Remove the bolts that secure the engine guard. After remove the cover, covering the timing belt and shafts. The power steering belt also remove it. If the car has power steering. Now you will interfere with only the alternator belt, so weaken it and remove. It is now possible to start removing the old belt.

Please lock the crankshaft, disconnecting the speed sensor and installed in the vacant window on the clutch unit wide screwdriver. She needs to get clear between the teeth of the crown. Before fixing the crankshaft need to set the first piston at top dead center. The camshafts need to put on labels and fix. Replace pump and install the new rollers. Now put on the belt and pull it.

Advice 7: When to change timing belt

Between the shafts (camshaft and crankshaft) in the engine of the vehicle is the timing belt. With it, the movement is transmitted from one shaft to another, and the belt wears out. When it is necessary to change?
How is the timing belt
With timing belt driven camshafts, and he, in turn, opens and closes the valves in the correct sequence. Thus, either the working area of the injected fuel, or generated exhaust gases.

When the timing belt needs to change



The timing belt is exposed to quite powerful forces, so it wears out. How to find out what time period it be replaced? If time does not deliver the new, the old can rupture valves in the engine can be bent. This entails a fairly expensive repair that will hurt the wallet of the car owner. Though the engines in modern cars are insured from similar troubles, still have problems.
Better change the timing belt, which still have margin of safety than to repair of the engine.


The timing belt should be replaced after 40 – 50 thousand kilometers if the car of the domestic automobile industry. If the car was bought in the cabin, new, during maintenance everything you need in the garage will replace based on the warranty card. If the car of foreign production, critical for timing the mileage is much higher, about 70 thousand kilometers. Despite what manufacturers claim a certain number of kilometers necessary for replacing the timing belt, it is better that figure to divide in half for domestic cars, and subtract 40% from the stated figures are imported. So it will be more reliable and safer.

If the car is purchased with it, that is already owned, the owner should be sure to ask when the belt was changed, and did he ever. If you do not know these things, need to start from the mileage. If you exceed 30 thousand km, you just need to change this part is not to risk. The repair will result in a larger amount than replacement. If you purchase a foreign car, then again, look at the mileage. There are 50-60 thousand km? To change unambiguously.

What should be the timing belt



Do not forget the proverb, that the avaricious pays twice.
It is best to put this part in the salon, and the one plant he sets out on a new car. In the Studio around the corner can offer to save it by putting another strap, but the case is unwinnable, because it will serve up 10 thousand km And change it again. The best option is the original timing belt for a particular brand of car. The rapid failure of the timing belt due to the fact that in the conditions of Russian winters on the Parking lots have to warm up the motor at least 15 minutes, all the while the speedometer readings don't change, but the wear is in full swing. And means to save on this part should not be.
