What Causes Shock Absorber Oil Leakage?
1 Answers
Shock absorber oil leakage can be caused by the following reasons: 1. Poor internal cleanliness of the shock absorber, with welding slag, iron filings, and other debris causing oil seal wear. 2. Harsh working conditions of the shock absorber, allowing external debris like mud and sand to enter the oil seal. 3. Aging of the sealing interface of the shock absorber oil seal, resulting in loss of sealing function. 4. Failure to properly cover the shock absorber during undercoating application, leading to coating adhering to the shock absorber piston rod. 5. The extension of the control piston rod at one end of the metal tube, where poor sealing occurs. Solutions for shock absorber oil leakage are as follows: 1. Oil traces on the shock absorber body do not necessarily indicate leakage. Determining whether a shock absorber is leaking or failing depends on factors such as the type of shock absorber, leakage level, and oil trace location. For shock absorbers with only minor seepage, replacement may not be necessary. Additionally, some oil seepage is normal during shock absorber operation. 2. However, for strut-type shock absorbers like front shock absorbers, if the oil film is between the oil seal cover and spring seat, replacement is not required. But if oil leaks below the spring seat or permeates below the spring bracket, or if oil droplets appear, the shock absorber should be replaced.
