8. Use only genuine Bendix

components and kits. Replacement hardware,

tubing, hose, ﬁ ttings, etc. must be of equivalent

size, type and strength as original equipment and

be designed speciﬁ cally for such applications and

systems.

9. Components with stripped threads or damaged

parts should be replaced rather than repaired. Do

not attempt repairs requiring machining or welding

unless speciﬁ cally stated and approved by the

vehicle and component manufacturer.

10. Prior to returning the vehicle to service, make

certain all components and systems are restored

to their proper operating condition.

11. For vehicles with Antilock Traction Control (ATC),

the ATC function must be disabled (ATC indicator

lamp should be ON) prior to performing any vehicle

maintenance where one or more wheels on a drive

axle are lifted off the ground and moving.

PREVENTIVE MAINTENANCE

Important: Review the Bendix Warranty Policy before

performing any intrusive maintenance procedures. A

warranty may be voided if intrusive maintenance is

performed during the warranty period.

No two vehicles operate under identical conditions, as a

result, maintenance intervals may vary. Experience is a

valuable guide in determining the best maintenance interval

for air brake system components. At a minimum, the valve

should be inspected every 6 months or 1500 operating

hours, whichever comes ﬁ rst, for proper operation. Should

the valve not meet the elements of the operational tests

noted in this document, further investigation and service

of the valve may be required.

SERVICE CHECKS

1. Remove any accumulated contaminants. Visually

inspect the valve's exterior for excessive corrosion

or physical damage. Repair/replace the valve as

necessary.

2. Inspect all air lines connected to the valve for signs

of wear or physical damage. Repair/replace as

necessary.

3. Test air line ﬁ ttings for excessive leakage and tighten

or replace as necessary.

OPERATIONAL AND LEAKAGE TESTS

1. Block the vehicle's wheels and fully charge the air

system.

2. Apply and release the service brakes several times

and check for prompt response of the brakes at all

appropriate wheels.

3. With the air system fully charged, apply a soap solution

or RE-6NC

Leakage of a 1" bubble in 5 seconds is permissible.

replacement parts,

valve's exhaust port.

4. Make and hold a full brake application and again

apply a leak check solution to the RE-6

valve's exhaust. Leakage of a 1" bubble in 3 seconds

is permissible.

5. With the brakes still applied, apply a leak check solution

around the valve where the cover meets the body. No

leakage at this point is permitted.

If the valve does not function as described; or if leakage is

excessive, repair the valve or replace it at any authorized

parts outlet.

REMOVAL

1. Identify, mark or label all air lines and their connections

to the RE-6

™

or RE-6NC

the body of the valve, including the valve cover.

When the assembly process is reached, the line will

serve as a reference to the position of the valve cover

on the valve body. Disconnect the air lines.

2. Remove the RE-6

vehicle.

INSTALLATION

1. Use the mounting bracket provided with the valve, or,

if securing the valve to a reservoir, use a Schedule 80

(heavy wall) short couple, pipe nipple.

2. Reconnect all air lines to the valve using the identiﬁ cation

made during removal.

3. Test all air ﬁ ttings for excessive leakage and tighten

as needed. Also, perform OPERATIONAL AND

LEAKAGE TESTS before placing the vehicle back into

service.

DISASSEMBLY

The following procedure is for reference only. Always

have the appropriate maintenance kit on hand, and use its

instructions in lieu of those presented here. Refer to Figure

12 throughout. CAUTION: The RE-6

may be lightly clamped in a bench vise during disassembly.

However, over-clamping will cause damage to the valve

and result in leakage and/or malfunction. If a vise is used,

position the valve so the jaws bear on the supply ports on

opposing sides of the valve's body.

1. Remove the four screws that secure the cover to the

body, set aside, and then slowly remove the cover.

2. Remove and discard the sealing ring(6) from sealing

ring grove located at the top of the valve body.

3. If a spring(5) is present (positioned between the bottom

side of the relay piston and the upper portion of the

valve body) set aside for the assembly process.

4. Remove the relay piston(3) from the valve body. It may

be necessary to tap the valve body lightly in order to

dislodge the relay piston from the valve cover.

5. Remove and discard the large o-ring(2) on the relay

piston.

6. Remove and discard the exhaust valve seat(4) from

the relay piston.
