Checking the removed shock absorber
Install the shock absorber in a vertical position
Check the condition of the shock absorber by moving the piston by the rod along the entire stroke length.
If jamming or lack of resistance is detected throughout the entire piston stroke, and obvious traces of fluid leakage through the oil seal are visible, replace the shock absorber.
- Cause of malfunction
Remedy
Fluid leakage from shock absorber:
- Loosening the reservoir nut
Tighten the nut
- Rod seal wear
Replace the oil seal
- Nicks or marks on the rod, wear of the rod until the chrome layer comes off
Replace the rod
The absence of a chrome layer is checked by the redness of the rod when wetting it with a solution of copper sulfate
Look at the article - “Gazelle shock absorber”
Unsatisfactory performance of the shock absorber (frequent breakdowns, car rocking):
- Insufficient amount of fluid in the shock absorber
Remove the shock absorber from the car, disassemble it, replace faulty parts and add fluid
Insufficient force during the recoil stroke (when stretching the shock absorber):
- Piston bushing wear
Replace the bushing
- Nadirs on the piston or cylinder
Replace damaged parts
- Leaky overlap of the bypass valve
Disassemble and wash the shock absorber. If necessary, replace the valve and its parts
Insufficient force (or “failures”) during the compression stroke:
- Loose closure of the compression valve due to foreign particles
Wash the shock absorber parts, fill with fresh fluid
Knocks and squeaks when the shock absorber operates:
- Looseness or wear of the bushings of the upper and lower shock absorber lugs
Tighten loose nuts. Replace damaged bushings
- Excessive amount of fluid in shock absorber
Pour liquid into the shock absorber in a strictly defined amount
- Self-loosening the recoil valve mounting nut
Tighten the nut
