Check of smoothness of movement of a rod of the shock-absorber
External manifestations which testify to malfunction of the shock-absorber:
– long rocking of a body at the movement on an uneven paving;
Check of a condition of the shock-absorber can be made manually or from an ispolzov niy the special equipment.
For check remove the shock-absorber from the car.
Check on all length of a rod of the shock-absorber for lack of pointed corrosion. Check the shock-absorber case for lack of mechanical damages. Install the shock-absorber in vertical position and check its work, moving a shock-absorber rod at full capacity. Also check operation of the shock-absorber, moving a shock-absorber rod up and down on distance of 50-100 mm. In all cases the rod of the shock-absorber has to move smoothly with a notable resistance. If the rod of the shock-absorber moves with breakthroughs or there are mechanical damages, the shock-absorber is subject to replacement, see rice. Check of smoothness of movement of a rod of the shock-absorber.
At the gas-filled shock-absorber the rod of the shock-absorber can spontaneously move forward from the shock-absorber. If there is no spontaneous promotion of a rod from the shock-absorber, it does not testify to malfunction of the shock-absorber. In this case the operating mode of the gas-filled shock-absorber corresponds to an operating mode of the hydraulic shock-absorber. The shock-absorber performs the functions and without the excessive pressure of gas, but at the same time additional noise when moving the piston of the shock-absorber can appear.
Check the shock-absorber for signs of leak of depreciation liquid. Small leak of oil at preservation of normal operability of the shock-absorber is allowed. If the spot of the liquid which flowed out from the shock-absorber reaches only the lower support of a spring, then it is considered the normal phenomenon. At an insignificant effluence of liquid from the shock-absorber there is also a lubricant of a sealing ring of a rod of the shock-absorber that increases the term of its service.
In the presence of strong leak of liquid from the shock-absorber, the shock-absorber needs to be replaced.
