DELIVERY CHECK VALVE CLEANING PROCEDURE

(Note: This is only required if system pressure does not build after temporary bypass is completed.)

Refer to Figure 6 throughout the following procedures. De-pressurize the air brake system following the general safety precautions outlined elsewhere in this document. Also, always de-pressurize the air dryer purge reservoir before servicing the air dryer.

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

1.Remove the line from the governor and mark for easy re-installation.

2.Remove the bolts attaching the governor to the AD-IS air dryer and reservoir system and retain for re-assembly.

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 re-assembly 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.

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

CLEANING & INSPECTION

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 Bendix® AD-IS®air dryer and reservoir system.) 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 any authorized Bendix parts outlets.

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