Automatic Level Control System Leak Test: Notes

Special Tools 

J 22124-B  Pressure Gauge (0-300 psi)

1. Disconnect the air tube from the air dryer.
2. Attach the air tube to the J 22124-B  pressure gauge on the side opposite the toggle valve.
3. Close the toggle valve.
4. Apply service air pressure to the service valve and pressurize until the J 22124-B  pressure gauge reads 550 kPa (80 psi).
5. Verify that the system maintains pressure for at least 1 minute.
   • If the system does not maintain the specified pressure for the specified amount of time, check the shock absorber air sleeves, air tubes, and all connections for air leaks using a soapy water solution. Repair or replace any leaking components.
