Advice 1: How to define a collapsible or non-collapsible stand

Front and rear stands is the most important element of the car's suspension, which are responsible for the smoothness and softness of movement. Currently, there are three types of struts: hydraulic, gas, and mixed type, they come in and dismountable.

The lifetime of the suspensions depends on several factors, which include the quality of the road surface, the nature of the drive, weather conditions and brand of the manufacturer. In an unfavorable combination of the factors above, the resource-pillars can be reduced to a minimum of several thousand kilometers. Conversely, if careful driving on good roads resource pillars may increase to 60 thousand kilometers. Unfortunately, a large majority of Russian roads is still the most bad reputation, and the problem of premature replacement of racks is very crucial. On cars that can be found today, there are two types of cushioning systems: and dismountable.

The vast majority of modern vehicles are equipped with a molded shock-absorbing systems. Their antipodes can be found on a few classic models. A typical representative of a portable system are the shock absorbers VAZ 2106. They are characterized as the traditional main parts: tank cap, cylinder, valve compression and the rod in combination with a piston and valves, guide Bush, nut, gasket and casing.

The working fluid is in the cylinder and the reservoir. In the lower part is rolled to the bottom, which serves to support the valve compression. From the outside to the bottom of the tank is welded to the bottom head of the shock absorber. Part of the compression valve includes housing, discs, plates, springs and clips. The valve body is compression made of sintered metal.

Very different look of modern nonseparable depreciation system. One of the world's largest manufacturers of shock absorbers is the Japanese company KAYABA, producing annually up to 50 million items. This series of attenuators allows the driver to modify the ride quality of the car in seconds, without the help of the Jack. All adjustments can be made using special convex disc on the surface.

Advice 2: How to identify a burned valve

In the process of operation of the vehicle is often the situation arises when its engine suddenly starts to run rough, or too clipped, as they say, "troit". The reasons can be several and one of them burnt out valve.
How to identify a burned valve
Instruction
1
To determine the exact cause and to establish what kind of valve went bankrupt, do the following.

- Run the engine at idle.

- Run the engine for a few minutes.

- Open the hood.

- Remove the cap from the spark of the first cylinder. If the engine speed is changed (slowed), this cylinder works.

- Put the cap back on and remove the cap from the spark to the second cylinder. Repeat the previous step for all cylinders.

- Check the operation of all cylinders, define broken. If the engine rpm when removing spark from cap has not changed - this cylinder is not working. This may be several reasons.
2
The first reason – the outside of the candle. Remove the spark plug and replace it with a new one (better to replace the whole set). Start the engine. If the engine works the same as before – a candle at anything. If the engine is stopped troit – the issue is resolved and she was all into the broken candle.
3
The second reason – the lack of spark on the candle, i.e., the wiring or the distributor. To check for spark remove the glow plug from the outside of the cylinder, put on her cap and put it on the engine. Scroll the engine a starter. If the spark is there, the electrician and the dispenser at anything. If there is no spark, check the distributor, distributor cap, Cam, wires, high voltage wires and caps.
4
If the ignition system is serviceable, there's two reasons why the engine troit: it's either a burnt valve or destruction of the piston (broken rings, sticking of piston rings, the destruction of the walls of the piston). Start the engine and let it run. In this case observe the breather. Then turn the engine off, turn the candle broken cylinder and inspect it. If the spark plug is clean and dry – burned valve. At the same time from the breather to get air or light smoke.
5
If the spark plug is wet with oil, and the breather out thick smoke, it means that the problem is in the piston: stuck or broken rings, or damaged piston. Performing such a test, it is possible to be 99% sure the reason why but the fact, and find out which of the valves failed.

Advice 3: How to make a collapsible stand

Collapsible absorbers produce some manufacturers, such as Kayaba, Tokico, and others. The great advantage of a portable stand is a lower cost repair of the unit than just replace it.
How to make a collapsible stand
You will need
  • - a set of keys;
  • liquid for boxes of automatic Dextron ATF;
  • - repair set for shock absorber;
  • - gas key.
Instruction
1
Remove the rack from the machine. To do this, disconnect all hoses, wires, and optionally the stabilizer links. Using the puller for the springs, compress the spring and remove the nut holding the upper seat, then remove it and remove the spring. Gently pry it spinning nut remover. Then remove from the stock front bump stop. All removed parts, inspect, maybe some of them need to be replaced.
2
With the help of a hacksaw on metal carefully cut zavartalanul upper part of the strut. This part does not pop up the bronze liner. Therefore, the saw carefully so as not to lead into disrepair liner. At the same time, do not be afraid shallow zapilov to a depth of not more than 1 mm into the body of the liner. Also, do not cut the absorber is too high, where there is already narrowing from rolling, because in this case you will not be able to remove the liner.
3
Cut the top of the rack pour from her old working liquid in the prepared capacity, measure how much was fluid in the absorber, and then remove the working mechanism, wipe the details from the working fluid with a cloth and inspect them. If the rack was leaking during use, it means you need to replace the stem seal.
4
Order your Turner ottercat upper part of the strut, cut the thread there with a height of 20-25 mm from the top and make a steel nut on it. Pay him attention so he did in the nut hole for the stock 2 mm larger than its diameter, and the thickness of the upper wall not less than 4 mm.
5
Rinse the inner part of the strut housings with gasoline to eliminate the possibility of getting shavings in the fluid that formed during the mechanical works. It will not hurt to wash and nut.
6
Assemble the stand, fill it with new fluid. For the filling stands you can use fluid for automatic transmissions ATF Dextron from any manufacturer. Pour slightly more liquid than it was. This will offset the loss of fluid through the seal. Replace the stem seal and install the top liner in place. Install the nut and using a gas wrench tighten. Bleed the rack by sliding the rod up and down. Make sure that the liquid does not flows out from under the screw connection and seal.
