AA4C Shock Absorber Oil Change and Nitrogen Charging Tool ZC-3515
The shock absorber oil change and nitrogen filling repair and testing equipment is a combination tool that includes a high-purity nitrogen gas machine, shock absorber damping testing machine, and a set of shock absorber filling joints. This equipment effectively solves problems such as shock absorber non-rebound and lack of damping, restoring shock absorbers to new car condition without replacement while maintaining original factory quality.
Equipment Operation Process
Connect the gas source to 220V power supply, turn on the power switch - equipment automatically produces high-purity nitrogen gas
Check initial damping of shock absorber and record data
Place pre-repair shock absorber at sensor mount position, press pressure zero button to remove shock absorber weight before conducting damping test
After damping data stabilizes on monitor, press save pressure button to store pre-repair damping data
Press filing function key, select corresponding start function key, insert quick connector into oil filling joint to begin filling with new oil
After new oil is filled, nitrogen will be filled and shock absorber pressure rod will rebound
After filling corresponding amount of nitrogen, press function button to stop filling, cover with cloth block, and pull out filling connector
Test repaired damping - display will show comparison data before and after repair
Drain old oil by finding matching filling joint and connecting filling tube quick connector
Seal and block, insert joint into shock absorber and invert it with oil drain port facing downward
Lift tooth joint upward to open oil seal and insert shock absorber - oil will discharge
Before draining oil, inject sufficient nitrogen gas into shock absorber for normal drainage
Inject oil into equipment by opening injector valve and injecting equal amount of new oil through syringe
Drain filling tube, unplug filling quick connect pipe to empty air, reinsert quick connect pipe, and close filling valve
Adjust filling pressure to 4KG through pressure regulating valve
