Preventive Maintenance

Important: Review the warranty policy before performing any intrusive maintenance procedures. An extended warranty may be voided if intrusive maintenance is performed during this period. Because no two vehicles operate under identical conditions, maintenance and maintenance intervals will vary. Experience is a valuable guide in determining the best maintenance interval for any one particular operation.

Every 900 operating hours; or every 25,000 miles or

three (3) months:

1.Check for moisture in the air brake system by opening reservoirs, drain cocks or drain valves and checking for the presence of water. If moisture is present, the desiccant cartridge may require replacement; however, the following conditions can also cause water accumulation and should be considered before replacing the desiccant:

A.An outside air source has been used to charge the system. This air does not pass through the drying bed.

B.Air usage is exceptionally high and not normal for a highway vehicle. This may be due to accessory air demands or some unusual air requirement that does not allow the compressor to load and unload (compressing and non-compressing cycle) in a normal fashion. Check for high air system leakage. If the vehicle vocation has changed, it may be necessary to upgrade the compressor size. Refer to Appendix A / Table A in this document. See the column titled Vehicle Vocation.

C.The air dryer has been installed in a system that has been previously used without an air dryer. The system will be saturated with moisture and several weeks of operation may be required to dry it out.

D.Location of the air dryer is too close to the air compressor. Refer to Locating the Bendix® AD-RP™Air Dryer On Vehicle section, plus Appendix A / Table A/ column 2 for discharge line length.

E.In areas where more than a 30 degree range of temperature occurs in one day, small amounts of water can temporarily accumulate in the air brake system due to condensation. Under these conditions, the presence of small amounts of moisture is normal and should not be considered as an indication that the dryer is not performing properly.

Note: A small amount of oil in the system is normal and should not be considered as a reason to replace the desiccant cartridge; oil-stained desiccant can function adequately.

2.Visually check for physical damage to the AD-RP air dryer such as a dented desiccant cartridge, chafed or broken air and electrical lines, and broken or missing parts.

3.Check mounting bolts for tightness. Re-torque to 50 lb-ft.

4.Perform the Operation & Leakage Tests listed in this publication.

Every 3,600 operating hours, or every 100,000 miles or twelve (12) months:

1.Test the AD-RP air dryer turbo cut-off and purge valves for leakage. Disconnect the supply, control and delivery lines from the AD-RP dryer. Perform the tests below in the order they are presented.

A.Apply 120 psi shop air pressure to the control port and a soap solution to the supply port. If leakage exceeds a one (1) inch bubble in ﬁ ve (5) seconds, repair the turbo cut-off piston and valve before proceeding to step 2.

B.With 120 psi shop air pressure applied to the control port, apply a soap solution to the purge exhaust port. If leakage exceeds a one (1) inch bubble in ﬁ ve (5) seconds, repair the purge piston and valve before proceeding to step 2.

C.With 120 psi shop air pressure applied to the control and supply port, apply a soap solution to the purge exhaust port. If leakage exceeds a one (1) inch bubble in ﬁ ve (5) seconds, repair the turbo cut-off piston and valve before proceeding to step 2.

D.With a plug installed in the delivery port, 0 psi in the control port, and 120 psi applied to the supply port, apply a soap solution to the purge exhaust port. If leakage exceeds a one (1) inch bubble in ﬁ ve (5) seconds, repair the purge piston and valve before proceeding to step 2.

2.Perform the Operation & Leakage Tests shown in this publication.

Every 10,800 hours; or every 350,000 miles or 36

months:

1. Replace the air dryer desiccant cartridge.

Note: The desiccant change interval may vary from vehicle to vehicle. Although typical desiccant cartridge life is three years, many will perform adequately for a longer period of time. In order to take maximum advantage of desiccant life and ensure that replacement occurs only when necessary, it is important that you perform the Operation & Leakage Tests.

2.Perform the Operation & Leakage Tests shown in this publication.
