Safety Precautions
When working on or around air brake systems and components, observe the following precautions:
• Chock the tires and shut down the engine before working under the vehicle.
• Depleting air system pressure may cause the vehicle to roll. Keep hands away from brake chamber pushrods
and slack adjusters; they will apply as air pressure drops.
• Never connect or disconnect a hose or line containing compressed air. It may whip as air escapes. Never
remove a component or pipe plug before all system pressure has been released.
• When working with compressed air, always wear safety glasses. Never look into air jets or direct them at
anyone.
• Never exceed recommended air pressure.
• Never attempt to disassemble a component prior to reading and understanding the recommended
procedures. Some components contain powerful springs, and injury can result if not properly disassembled.
Use the correct tools, and observe all precautions pertaining to use of those tools.
• Replacement hardware, tubing, hose, fittings, etc., should be the equivalent size, type, length, and strength
of the original equipment. Make sure that when replacing tubing or hose, all of the original supports, clamps,
or suspending devices are installed or replaced.
• Replace devices with stripped threads or damaged parts. Repairs requiring machining should not be
attempted.

Air Tank Mounting Bracket Inspection and Replacement
NOTE: Perpendicular mounted air tanks may be installed on either or both frame rails, and may have two sets on
one side or the other.
1. Check the base label (Form WAR259) for a completion sticker for SF501 indicating this work has been done.
The base label is usually located on the passenger-side door about 12 inches (30 cm) below the door latch.
If a sticker is present, no further work is needed. If there is no sticker, proceed with step 2 below.
2. Park the vehicle on a level surface, shut down the engine, and set the parking brake. Securely chock the tires.
3. Check each air tank mounting bracket to determine if it is the older 3/16-inch steel or the new 1/4-inch thick
steel. See Fig. 1 and Fig. 2.
If the bracket is the new 1/4-inch thick steel, no further work is needed. Proceed to the last step.
If the bracket is the older 3/16-inch thick steel, proceed to step 4.
4. Drain the air from the air tanks.
5. Mark or tag all tank air lines, couplers, and valves for later assembly, then disconnect the components. Cap
the exposed ports tightly to keep out contaminants.
