DISASSEMBLY FOR PART REPLACEMENT AND KIT INSTALLATION

1.The following disassembly and assembly procedures are presented for reference and assumes that the appropriate Bendix® AD-RP™air dryer kits are on hand. The instructions provided with these parts and kits should be followed instead of the instructions presented here.

2.The replacement parts and maintenance kits that are available do not require full disassembly and in most cases do not require the removal of the AD-RP air dryer from the vehicle.

3.If removal of the air dryer is necessary, adhere to the following caution:

CAUTION: While performing service on the AD-RP air dryer, it is not recommended that a clamping device (vise, C-clamp, etc.) be used to hold any die cast aluminum component as damage may result. To hold the body, install a pipe nipple in the supply port and clamp the nipple into a vise.

DISASSEMBLY - TURBO CUT-OFF VALVE

1.Loosen the supply port line and allow any residual air in the compressor discharge line to drain.

2.Remove the retaining ring from the body assembly, then remove the turbo cut-off cap from the body. Remove the turbo cut-off cap o-ring.

3.Remove the turbo cut-off piston from the body.

4.Remove the large and small diameter o-rings from the piston.

DISASSEMBLY - PURGE/RELIEF VALVE

1.If so equipped, disconnect, remove and save the exhaust line from the exhaust port of the air dryer.

2.Remove the retaining ring from the body assembly, then remove the non-metallic exhaust cover and spring from the body. Note: The spring exerts a 30 pound force against the exhaust cover.

3.Carefully remove the purge piston from the body and remove the o-ring from the purge piston.

4.The purge valve has two different sides. Note which side is visible before removing the valve. Remove the valve from the body.

DISASSEMBLY - HEATER AND THERMOSTAT

1.Disconnect the vehicle wiring harness connector that mates with the heater and thermostat connector on the body. Pry the lock tabs on the vehicle wiring harness connector out, before removal from the air dryer connector. Make sure the connector seal is present on the vehicle wiring harness connector.

2.Remove the retaining ring that secures the heater and thermostat in the body.

3.Carefully pull the heater and thermostat assembly straight out of the body.

4.Remove the o-ring from the heater connector.

DISASSEMBLY - DESICCANT CARTRIDGE

1.Place a strap wrench, or equivalent tool, on the desiccant cartridge next to the lip low on the cartridge. Rotate counterclockwise to remove the desiccant cartridge.

CLEANING, INSPECTION AND ASSEMBLY PREPARATION

1.Clean the exterior of the body.

2.Using a clean rag, wipe the body bores clean.

3.Inspect for physical damage to the body casting, broken and/or missing parts.

4.Inspect the interior and exterior of the body for severe corrosion, pitting and cracks. Superfi cial corrosion and/ or pitting on the exterior portion is acceptable.

5.Inspect the bores, valve seating and o-ring contact areas for deep scuffi ng or gouges or nicks that would not permit an air tight seal.

6.Inspect the pipe threads in the body. Make certain they are clean and free of thread sealant.

7.Inspect the purge valve piston seat for nicks and excessive wear.

8.Inspect all air line fi ttings for corrosion. Clean all old thread sealant from the pipe threads.

9.All o-rings removed should be discarded and replaced with new o-rings provided in the appropriate kit(s).

10.Lubricate the body bores and o-ring grooves, in the body and components, with the grease supplied in the Bendix® maintenance kits.

11.Lubricate all o-rings with the grease supplied in the Bendix maintenance kits. Any component exhibiting a condition described in steps 3 to 8 should be replaced.
