7. Remove and discard o-ring(7) from under the crimped-

on retaining ring located in the upper portion of the valve
body.

8. Turn the valve over, holding the exhaust cover, remove

the 3 cap screws(27) from the exhaust cover(22).
Remove the spring(20) and set the cap screws and
spring aside for the assembly process.

9. Remove and discard the small o-ring(19) from the

exhaust cover (located on the check valve post).

10. The RE-6NC

™

valve will not have a check valve(17)

and spring(18).

11. Remove and discard the check valve (17) and spring(18)

in the RE-6

™

valve.

12. Remove and discard the diaphragm(23) from the

exhaust cover. Set screw(25) and washer(24) aside
for the assembly process.

13. Remove the emergency piston(9) and inlet / exhaust

valve(10) assembly by pushing the assembly through
the valve body, from the relay piston side of the valve.
The whole assembly will come out of the valve body
as one unit.

14. Remove and discard o-ring(8) located in the grove of

the emergency piston.

15. Remove and discard o-ring(21), which creates the

seal between the emergency piston and the exhaust
cover.

16. Remove valve retainer(16) with appropriate pliers and

set aside for the assembly process.

17. Remove and discard all internal parts. Valve guide(15),

o-rings(13&14), spring(12), valve retainer(11), inlet /
exhaust valve(10).

CLEANING & INSPECTION

1. Using mineral spirits or an equivalent solvent, clean and

thoroughly dry all metal parts. Do not damage bores
with metal tools.

2. Wash all non-metallic components in a soap and water

solution. Dry thoroughly.

3. Inspect interior and exterior of all metal parts for severe

corrosion, pitting, and cracks. Superfi cial corrosion
and/or pitting on the exterior of the body and cover is
acceptable. Replace the entire valve if the body or
cover interior show signs of corrosion or pitting.

4. Inspect each non-metallic component for cracks, wear,

or distortion. Replace the valve if these conditions are
found.

5. Make certain the air channel running from the cover

through the top surface of the body to the supply port
is clear and free of obstruction.

6. Inspect the pipe threads in the body. Make certain they

are clean and free of thread sealant.

7. Inspect all air line fi ttings for corrosion. Replace as

necessary. Remove all old thread sealant before
reuse.

ASSEMBLY

Before assembly, lubricate all o-rings, seals, and pistons as
well as body and cover bores, using the lubricant provided
in the maintenance kit. Use all of the lubricant, and spread
it evenly on the rubbing surfaces.

1. Install o-ring(8) into the grove on the emergency

piston(9).

2. Install the inlet / exhaust valve assembly into the

emergency piston. Packaged as 1 unit.

3. With Tru-Arc pliers, install valve retainer(16), making

certain it is in the grove in the emergency piston.

4. Install the emergency piston(9) (including the inlet /

exhaust valve assembly just installed) into the valve
body.

5. Install the spring(20) in body.

6. Install o-ring(19) on to the check valve post, located on

the exhaust cover.

7. Install the diaphragm(23) on to the exhaust cover,

securing it with the screw(25) and washer(24) set aside
in the disassembly process.

8. For the RE-6

™

valve, install the small check valve

spring(18) on to the check valve(17) and drop into the
check valve cavity. The spring will fi t in groove on the
exhaust cover (making sure spring is positioned in the
center of the cavity). If changing the RE-6NC

™

valve,

discard the check valve(17) and spring(18).

9. Install o-ring(21) into channel between the valve body

and emergency piston.

10. Turn the valve over and install o-ring(7) in the channel

under the crimped-on retaining ring located in the upper
portion of the valve body. (This must be done before
the exhaust cover is installed because the emergency
piston will cover this o-ring).

11. Turn the valve back over and install the exhaust

cover(22). Install cap screws and lock washers, torque
to approximately 100 inch pounds.

12. Turn the valve over and install the sealing ring(6) in

the grove located at the top of the valve body.

13. Apply the adhesive sealant to the seat(4) threads and

install in to the relay piston.

14. Install the o-ring(2) around the relay piston(3).

15. Insert the relay piston(3) into the valve cover(1) and

push the piston to the top of the cover.

16. If so equipped, install the piston return spring(5).

17. Install the cover to body, making certain the scribe

marks line up marked in the "REMOVAL" section.
