Shock-absorber check
GENERAL INFORMATION

The following signs indicate malfunction of shock-absorbers:

– Additional fluctuations of a body at movement on roughnesses of the road.
– Increase of amplitude of fluctuations of a body at the following one after another roughnesses of the road.
– Jumping of wheels at movement on the normal road.
– An involuntary turn of the car when braking. Can be a consequence of other reasons.
– Instability on turns owing to bad coupling with a paving.
– The increased wear of tires with a cut of tops of drawing of a protector.
– A sign of defective shock-absorbers are also existence of roaring noise. This noise can be a consequence and other reasons, for example, an otvorachivaniye of bolts of fastening and nuts, failure of bearings of wheels and hinges of equal angular speeds. Therefore before replacement of shock-absorbers always check their condition.

The shock-absorber can be checked manually. However exact check of operation of shock-absorbers is possible only with the help shock – a tester or the special verifying car.

Check manually

PERFORMANCE ORDER
1. Remove the shock-absorber.
2. Establish the shock-absorber into position, put forward and compress it. Throughout all course the shock-absorber should move exactly and smoothly.
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.
