ASSEMBLY
Note: All torque specified in this manual are assembly torque
and can be expected to fall off slightly after assembly. Do
not re-torque after initial assembly torque fall. For assembly,
hand wrenches are recommended.
Prior to assembly, lubricate all o-rings, o-ring bores and any
sliding surface with a silicone lubricant equivalent to Dow
Corning #10.
1. Install large piston o-ring on piston.
2. Install inner and outer o-rings in the exhaust cover
assembly.
3. Install the sealing ring on the cover.
4. Install piston in body, taking care not to damage the
piston o-ring.
5. Noting the reference marks made during disassembly,
install the cover on the valve body and the mounting
bracket on the cover.
6. Secure the mounting bracket and cover to the body using
the four (4) cap screws and lock washers. Torque to 80-
120 inch pounds.
7. Install the valve retainer on the inlet/exhaust valve and
install in the body.
8. Install the inlet/exhaust valve return spring in the body.
9. Install the exhaust cover assembly in the body, taking
care not to damage the o-ring.
10. While depressing the exhaust cover, install the retaining
ring. Make certain the retainer is completely seated in
its groove in the body.

11. Install the R-14
valve service port cap nut o-ring on the
cap nut.
12. Install the diaphragm in the R-14
certain it is positioned between the guide ribs in the
cover.
13. Install the service port cap nut and torque to 150 inch
pounds.
14. If the quick release exhaust port was protected with an
exhaust cover, install the cover using the #10-24 Phillips
head screw. Torque to approx. 15-25 inch pounds.
15. Test the valves as outlined in the Operational and Leakage
Test section before returning the valve to service.

WARNING! PLEASE READ AND FOLLOW
THESE
INSTRUCTIONS
PERSONAL INJURY OR DEATH:
When working on or around a vehicle, the following
general precautions should be observed at all times.
1. Park the vehicle on a level surface, apply the
parking brakes, and always block the wheels.
Always wear safety glasses.
2. Stop the engine and remove ignition key when
working under or around the vehicle. When
working in the engine compartment, the engine
should be shut off and the ignition key should be
removed. Where circumstances require that the
engine be in operation, EXTREME CAUTION should
be used to prevent personal injury resulting from
contact with moving, rotating, leaking, heated or
electrically charged components.
3. Do not attempt to install, remove, disassemble or
assemble a component until you have read and
thoroughly understand the recommended
procedures. Use only the proper tools and observe
all precautions pertaining to use of those tools.
4. If the work is being performed on the vehicle's air
brake system, or any auxiliary pressurized air
systems, make certain to drain the air pressure from
all reservoirs before beginning ANY work on the
vehicle. If the vehicle is equipped with an AD-IS
air dryer system or a dryer reservoir module, be
sure to drain the purge reservoir.
5. Following
the
recommended procedures, deactivate the electrical
system in a manner that safely removes all
electrical power from the vehicle.
6. Never exceed manufacturer's recommended
pressures.
7. Never connect or disconnect a hose or line
containing pressure; it may whip. Never remove a
component or plug unless you are certain all
system pressure has been depleted.
8. Use only genuine Bendix
components and kits. Replacement hardware,
tubing, hose, fittings, etc. must be of equivalent
size, type and strength as original equipment and
be designed specifically 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 specifically 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.
