INSTALLATION

The straight SC-3

™

check valve consists of a two piece

body. When installing the valve, tighten using the hex

surface that is closest to the port that it is being installed in.

See Figure 4. This will prevent breaking the seal between

the two halves which would cause leakage.

OPERATION & LEAKAGE CHECKS

NOTE: Depending upon installation, it may be easier or

necessary to completely remove check valves so that the

following checks may be made.

With air pressure present at outlet side of check valve and

the inlet side open to atmosphere, coat the open end of

the check valve with soap suds; a 1” bubble in 5 seconds

is permissible (100 SCCM).

If the check valve does not function as described, or

leakage is excessive, it is recommended that it be replaced

with a new genuine Bendix part available at any Bendix

parts outlet.

REMOVAL

Block and hold vehicle by means other than air brakes.

Completely drain all reservoirs.

Disconnect air lines at single check valve and remove.

DISASSEMBLY/ASSEMBLY

Note: There are no Disassembly/Assembly procedures for

SC-3

™

valves. They are non-serviceable items. If a valve

does not meet the Operational and Leakage tests, it should

be replaced at any authorized Bendix parts outlet.

TESTING AND TROUBLESHOOTING

Perform “Operating and Leakage Checks”.

GENERAL SAFETY GUIDELINES

WARNING! PLEASE READ AND FOLLOW THESE

INSTRUCTIONS TO AVOID 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 vehicle manufacturer’s 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

replacement parts,

components and kits. Replacement hardware, tubing,

hose, ttings, etc. must be of equivalent size, type

and strength as original equipment and be designed

speci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

speci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.
