4.2.4. Check of the removed shock-absorber

Defective shock-absorbers prove in movement by loud extraneous knocks (as consequence of a wheel course), and, in particular, on bad road. Especially it is appreciable at strong leak of oil.

Shock-absorbers are unattended details, having added oils is impossible.

The removed shock-absorber преверяется manually as follows.
Manually compress the shock-absorber.
The rod should move on all length of a course in regular intervals hard and without jerks
Release a rod.
On shock-absorbers with sufficient pressure of gas the rod independently leaves in a starting position.

If it does not occur, to change the shock-absorber not necessarily. While there is no big leak of oil, the action principle corresponds to work of the usual shock-absorber.
Amortizirujushchee action completely remains and without pressure of gas while there is no big loss of oil. However шумность can be raised.
