The owner of the car, even who does not even love to do with his own hands, should know the device of his car and find, if necessary, the necessary mechanism. Since the timing belt is an important detail in the work of any car, the car owner should know the device of this mechanism and where this mechanism is located. The instruction of each car tells in detail and applies pictures, how the desired mechanism looks like. The timing belt in the form of a rubber gear belt covers the pulleys and is a link. The task of the timing belt includes ensuring the synchronized work of the crankshaft and the camshaft, the technology of the operation of this unit provides a hook of several more important auxiliary units. And so, we conclude that the timing belt is in constant work, being an important detail of the car and therefore his service life is not very large.

Timing belt, its design

The belt is a closed ring, with the inside of the ring there are special notches, they are also called the timing tags.

Modern cars are very often equipped with timing belts that are made of rubber.

Rubber timing belts do not emit noise and are not subject to corrosion. The design of the timing belt consists of a water pump, pulling roller and seals.

The duty of the tensioning roller includes providing additional belt tension.

If the pulling roller wear out, the timing belt will begin to sign and quickly wear out.

Professionals say that if you are forced to change the timing belt - buy an original product, thereby preventing the car from the premature belt cliff.

When replacing the timing belt, change the roller and the pump at the same time.

Timing belt than threatening the cramp timing

The breakdown of the timing belt threatens the failure of the valve group, and then the most serious breakdowns of other parts of the engine occur.

The breakdowns occur due to the fact that modern engine engines have a high torque.

And if the question is about replacing the timing belt, it is necessary to carefully examine all the elements of the timing belt.

After the rupture of the timing belt, the camshaft will stop his work, and the crankshaft will continue to spin.

Regardless of the transmission and motor turns, the pistons with a large force beaten on the valves of the motor.

Because of this, the valves are bend.

In practice, there are cases when the valve breaks through the piston.

Timing belt, why he can break

The reasons for the timing belt is a lot, we will specify the main:

-Rell TRG operated a long time and came in disrepair;

-Rell timbering was low quality (not original);

-The pump pump is the most common cause;

-roliki jammed;

- The pulling roller is adjusted;

- for breakdowns the camshaft jammed;

- Cranked crankshaft.

Timing belt how to warn belt rupture

The breakdown is better to warn, and for this you need to adhere to certain rules:

-time, according to the instructions, change the timing belt;

-Cook attention to the condition of the glands, see whether the spots of the oil on the asphalt remain;

-Do you miss the oil pressure emergency light bulb if the light bulb caught fire, stop the car and find out the cause of the emergency lighting;

-In the case of replacing the timing belt, use only original parts of all components;

- hold for the tension of the timing belt and its condition;

- Do not even slightly skip the drive, when the noise appears, inspect the rollers and water pump.

Professionals are recommended, changing the timing belt every 50,000 km. Mileage, and if the machine is exploited a little, the timing belt must be changed every 6 years, simultaneously changing the tension roller.

Do not be lazy and every 40 - 45 thousand kilometers of run. Check the status of the timing belt, when identifying signs of damage or wear, the belt must be replaced.

Timing belt how to check the belt tension

To check the belt tension, remove the air filter and remove the timing belt cover, you may have to remove the decorative engine cover. Grasp the belt with two fingers and twist it around the axis, the belt must be screwed by 90 * around its own axis.

More accurate tension can be checked using special devices. If the belt is tightened above the norm, it will quickly wear out, the water pump and the tensioning roller fail.

If the belt is tightened poorly, it will be the cause of the leakage of the belt on the tooth and because of this, the gas distribution phases are disturbed.

Timing belt, how to replace it with your own hands

Before replacing the timing belt, it is necessary to dismantle the old belt.

Initially, turn off the "minus" terminal from the battery and remove the generator drive belt.

Next, we set the piston of the first cylinder to the position "Upper Dead Point".

The key (15), unscrew the bolt that crept the roller, slightly turning the roller itself, reduce the belt tension.

Next, remove the timing belt from all pulleys.

At this point, the assistant must fix the crankshaft with a large screwdriver and hold it.

And at this time you remove the plug from the clutch crankcase.

Using the key 17, unscrew the crankshaft pulley bolt and remove it, then dismantle the slotge of the generator drive.

Gently remove the timing puck of the timing belt and remove the timing belt itself from the crankshaft pulley.

Disassembly is over, now clean the pulleys and the tensioning roller from the oil and dirt. You can use Whitepite or with a rag of moistened gasoline. Install the new timing belt and do everything in order opposite to the removal.

At the same time, follow the rules:

-Chis generator drive is installed in a special recess;

- Installing the belt, create an optimal tension of the leading branch;

- Replace the special key to stretch the belt, insert it into the tension roller grooves and turn the roller counterclockwise. The roller must be rotated until the external disk becomes flush with a rectangular protrusion not its external sleeve;

- Use the key to 15 when the bolt is tightening, which fixes the roller;

- Check all tags;

-If after replacing the timing belt, there will be noise from the camshaft drive, which means the tensioning roller bearing broke, the roller will have to be replaced.

Timing belt how to replace the tension roller with your own hands

In a specialized store, buy the original part of the stretch roller, make an installation in order opposite to install the timing belt.

Making a replacement, follow the holes for a special key, were outside.
