Timing Belt Replacement

 

Beginner drivers who do not understand the car business, mistakenly consider the timing belt is not too "serious" element in the work of the car. However, experienced drivers are well aware of how important it is that the timing belt is always in good condition.

 

Stretching between the crankshaft and camshaft pulleys, it connects the operation of the lower and upper part of the engine: that is, synchronizes the operation of valves and pistons.

 

The timing belt is located in the front of the engine. In most cars, it is covered with protective covers, but in older models, such covers may be missing.

 

The most common today are toothed, V-belts and V-belts. Timing belt - complex structurally, but it is considered the most effective.

 

Modern belts are made of durable elastic materials. On the inner surface of the belts are teeth that provide a secure engagement with the pulleys. But it is important to know that there are no universal timing belts! For each car model develop their own, which differs in length and number and shape of teeth.

 

Drive to replace the timing belt

 

During operation of the car one way or another the belts weaken and wear out. If you do not stretch to the desired value in time, there will be "slipping" and "jumping" of the teeth. This will cause the ignition and gas to fail.

 

The biggest problem is belt breakage. In this case, the camshaft and valves "freeze", and the crankshaft continues to rotate and sends the piston up. As a result, we have a "collision" and deformation of the valves.

 

Only timely diagnosis and scheduled replacement will help to avoid the problem. At the slightest violation of the integrity of the belt should be replaced regardless of service life. Here are the signs that the timing belt has become unusable and needs to be replaced:

 

  • worn surface;
  • abrasion of teeth due to incorrect tension, problems with the bearing or under the influence of high temperatures;
  • cracks and peeling;
  • curing (loss of flexibility) of the belt;
  • stretching of the structure;
  • deviation from the working position due to a malfunction of the tension roller;
  • uneven engine operation.

How often is the timing belt replaced?

 

Manufacturers usually indicate the recommended replacement dates for the car's owner's manual. In some brands of cars it is designed for 100 thousand km, in others - only 50 thousand km. But it is important to know that there are many factors that affect the wear of the belt, independent of the manufacturer.

 

Aggressive driving style, too high engine speed (especially in winter) lead to the fact that the belt wears out faster. Also shortens the service life of the timing improper installation on the labels or too strong or weak tension.

 

Is it possible to replace the timing belt yourself?

 

It is possible. To do this, you need:

 

  1. buy a new spare part;
  2. remove the protective covers (if they are in your car);
  3. turn the belt to the position in which the marks on the pulley and the camshaft cover sing) will fall (ie, the piston of the first cylinder will be in the upper "dead" point;
  4. fix the flywheel (insert the pin between the teeth) to prevent the crankshaft from turning;
  5. remove the generator pulley;
  6. loosen the tension roller and bring it to the extreme position (least tension);
  7. remove the old belt;
  8. put a new product on the crankshaft and pump pulleys;
  9. to get a belt for a tension roller and then to fix on a camshaft pulley;
  10. adjust the tension.

 

Are you sure you can handle it? Then - good luck! If there are doubts (and they are not unfounded, because in general this procedure is not simple), it is better to trust the professionals. After all, any inaccuracy or inattention during self-replacement of the GMR belt can lead to engine failure. And this is a much more expensive repair, which will have to turn to professional craftsmen. So is it worth paying more?
