Each owner of the vehicle, regardless of its brand and dimensions, is certainly aware of what a significant role will play shock absorbers in the design of the car. Their main tasks are the trimming of the suspension vibration, increasing control of controllability by road, improving the contact of the wheels with the roadpapers. Shock absorbers, exactly as any other parts of the car require careful and careful relationship, systematic service, careful selection, as well as the right installation. About this further in the article.

Shock absorbers for what they need and where they are installed

The vehicle during overclocking "cries" back, unloading the front and loading rear wheels, which reduces their grip with a road surface. When braking, the other way around. Both in the first and in the second case, it would be ideal for the position at which the machine would retain their normal "horizontal" position.

Approximately the same picture is observed during maneuvering, but the load is shifted here on the sides of the car, and not along the axes.

Shock absorbers hold the wheels in constant contact with the roadbed so that the driver does not lose control of the vehicle. Install racks directly near the vehicle wheels.

What oil shock absorbers are better

1. Koni is the most expensive shock absorbers, however, the most durable. These racks are the development of the Dutch company of the same name. Apply actually on all types of transport. Available in the possibility of adjusting the characteristics.
   
2. Bilstein - a symbol of reliability and quality. Are rather common. Installed on the following brands of cars - Ferrari, "Jaguar", "Lamborghini".
3. BOGE - produces a well-known company from Germany. Completed for mounting on cars of the following concerns - "Volkswagen", "Audi", "BMW", "Alpha Romeo", "Volvo". They differ available to the cost and actually do not change the characteristics of suspension of modern foreign cars.
4. Monroe is one of the best American companies. Its products are mounted on new vehicles of America and all of Europe. One of the best developments is the "Reflex" series shock absorbers, which are able to provide maximum contact with the roadpapers.
   
5. Tokico is one of the largest manufacturers of racks in Japan. The reasons for the popularity of this product are low price, high quality and long service life. However, when purchasing these products, beware of Chinese fakes.
6. Sax - These products manufactures the German company. As it should be, all products are distinguished by reliability and high quality.
7. Kayaba - a Japanese company manufacturing this product appeared on the market in 2000 and in fact immediately won wide popularity. The main visories of the company are good quality, rich product aunts and low cost. Kayaba delivers its products for Mazda, Toyota and Honda.

Pumping the shock absorber, why need to pump the shock absorber before installing

Pumping oil shock absorbers are produced to bring them into the working condition:

1. In order not to be left oil or air (gas supply) in the inner liner sleeve, which can lead to the exit of the shock absorber.
2. To diagnose a likely jamming of the valve mechanism of the rack or other faults.

If the usual two-pipe shock absorber before installing the vehicle does not pump, it may fail its piston group. In addition, in this case, the warranty on the product does not apply, that is, it is simply "money to the wind".

It is important to know that insignificant failures may be observed in the resistance of the valve mechanism, which is not considered a malfunction, since this is not reflected in the overall performance of the device.

Pumping shock absorber, general rules for pumping

1. Shock absorbers pump up vertically (rod up).
2. After performing the pitching of the rack, it should be kept in a vertical position, stock up until you install it on the vehicle.
3. Some structures of shock absorbers provide a system for draining oil. Methods: either using a technological groove, which is located at the top of the rod, or by the failure of the rod inside the rack. In the latter case, the rod of the rack should be left uncompressed by 2-3 centimeters. In the first case, the rod is compressed to the technological groove, which is located on it.

Pumping oil shock absorbers, how to make oil shock absorbers

Mac-Fersson shock absorbers are standard for modern cars.

Therefore, we consider the technology of pumping racks on their example:

1. I turn down the shock absorber to the rod and smoothly, squeeze it without jerks.
2. Fix the shock absorber in this position for three seconds.
3. I turn over the shock absorber up the rod, holding the rod, and fix it for six seconds in this position.
4. Next, smoothly put forward the rod until the end of the stroke.
   
5. I turn down the robes down again, we make a small pause (three seconds) and repeat the procedure. The number of approaches is from 1 to 6.

With the third approach, make a control action - the shock absorber is located vertically, stock up, short sharp movements are convinced that the stroke of the rod smooth. The piston should also move smoothly, without failures.

Tips Prof.

Pumping the shock absorber can be considered complete, if everything is fine and the movement of the rod smooth. Similar activities for pumping and other racks before mounting on the vehicle. It is recommended, however, it is not necessary to replace the shock absorbers in pairs, i.e. simultaneously on the same axis.
