The shock-absorber can be checked manually. However exact check of work of shock-absorbers is possible only by means of a shock-tester or the special verifying car.
1 Remove the shock-absorber.
3 At газонаполненных shock-absorbers at sufficient pressure of gas the rod itself comes back in a starting position. If the rod does not come back, it does not mean necessity of obligatory replacement of the shock-absorber. Its principle of action corresponds to a principle of action of the usual shock-absorber until there is no considerable leak of oil. Dempfirujushchee action of the shock-absorber remains also in the absence of pressure of gas. However its noise characteristics thus worsen.
4 At normal functioning of the shock-absorber insignificant traces of the flowed out oil are not the basis for its replacement. A key rule here is the following: if the oil acting from an epiploon of a rod, is visible, but it does not extend further the bottom plate of a spring the shock-absorber is serviceable. Insignificant leaks of oil have even some advantage as the epiploon is thus greased that promotes increase in its service life.
5 At considerable leaks of oil the shock-absorber is subject to replacement.
