Guidelines outlined on pages 5-6 in this document. Also, always depressurize the air dryer purge reservoir before servicing the air dryer.

This procedure does not require removal of the AD-IS®air dryer from the vehicle.

1.Remove the line from governor and mark for easy reinstallation.

2.Remove the bolts attaching the governor to the AD-IS®air dryer and retain for reassembly.

3.Remove the governor from the air dryer. Be aware that a short puff of trapped air may vent when the governor is removed. Retain the governor gasket for reassembly if a new governor gasket is not available. Remove and retain the o-ring from the adapter.

4.The spring/delivery check valve can now be removed. A second delivery check valve is located in the dryer without a governor. This check valve is located behind a hex head plug near the control line from the EverFlow™ module to the air dryer. Carefully remove the hex plug and follow the instructions that follow.

5.Remove and retain the o-ring from check valve body.

Consult the service data sheet for the dryer used in your AD-IS®EverFlow™ assembly. The service data sheet contains information useful for maintenance and service of the air dryers.

1.Use a suitable solvent to clean all metal parts, and use a cotton swab to clean the bore (Note: Do not use abrasives or tools to clean the bore: any scratches caused may necessitate replacing the AD-IS®air dryer.) Superﬁcial external corrosion and/or pitting is acceptable.

2.Clean the o-rings with a clean dry cloth. Do not use solvents.

3.Inspect for physical damage to the bore and the check valve seat. If the bore is damaged (by scratches etc. that would prevent delivery check valve from seating), replace the AD-IS®air dryer.

4.Inspect the delivery check valve, o-rings, etc. for wear or damage. Replace if necessary using the check valve replacement kit available at authorized Bendix parts outlets.

5.Inspect all air line ﬁttings for corrosion and replace as necessary.
