What is the key to the maintenance of shock absorbers?

In daily use, the maintenance of shock absorbers is also a big problem that cannot be ignored. Then you know where the focus of shock absorber maintenance is? When the chassis sinks and the body becomes low, there are usually several reasons:

One is that the metal spring fatigue caused by the spring to reduce the ability to recover;

Second, it is caused by oil leakage due to wear and deformation of buffer tubes and other parts;

The third is caused by the aging of hydraulic oil;

Fourth, oil seal aging caused by oil spills.


One of the important causes of oil leakage is that the shock absorber has a trauma or rust. Therefore, when the car falls and is impacted by an external force, it is necessary to check whether the shock absorber's heart is deformed in a timely manner and whether the oil seal is damaged. This requires that the shock absorber heart be injured and rust as the focus of daily maintenance. Should also pay attention to check the shock absorber oil seal and dust cover for oil leakage, or see if there is no dirt and dirt attached, and timely clean the shock absorber and the relevant parts to ensure that the shock absorber does not leak oil. If the shock absorber buffer tube is oxidized and rusted, it can be polished with a metal abrasive to make it smooth. Also check that the front shock absorber is scratched or rusted, as this is one of the important causes of oil leakage from the shock absorber seal.

To check whether the connecting rod oil seal leaks hydraulic oil, if a leak has occurred, it must be replaced or repaired by an expert. The dirt on the buffer cylinder connecting rod must be cleaned with a soft cloth. If oxidative rust has occurred, it should be immediately removed with a metal abrasive. The connecting rod part of the rear wheel buffer tube should be checked for sediment, dirt accumulation, scratches, rust, etc. If there is any such situation, it should be promptly cleaned or repaired.
