The shock-absorber can be checked manually. However exact check of operation of shock-absorbers is possible only with the help shock tester or the special verifying car.
1 Remove the shock-absorber.
3 At gas-filled shock-absorbers at sufficient pressure of gas the rod itself comes back to a starting position. If the rod does not come back, it does not mean need of obligatory replacement of the shock-absorber. Its principle of action corresponds to a principle of operation of the ordinary shock-absorber until there is no considerable leakage of oil. Dempfiruyushchey operation 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. The basic 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 leakages of oil have even some advantage as the epiploon is thus greased that promotes increase in its service life.
5 At considerable leakages of oil the shock-absorber is subject to replacement.
