4-23. AIRBRAKE SYSTEM LEAKAGE CHECK.
a.
Connect intervehicular and intradolly gladhands (see paragraph 2-11).
b.
Fully pressurize dolly set airbrake system (see towing vehicle Operator’s Manual).
c.
Apply a solution of detergent (Item 13, Appendix F) and water to front and rear dolly gladhands, air
hoses, fittings, air reservoirs, brake chambers, and valves.
d.
Make note of any leaks, damage, or loose connections found. Tighten loose connections and replace
damaged components.
4-24. ANTISEIZE TAPE.
When connecting air hoses and fittings without compression sleeves or packings, antiseize tape (Item 29,
Appendix F) may be used to keep connections from leaking. Use as follows:
If threads are not clean and dry and antiseize tape is not clean, leaks can occur.
(1)
Ensure that threads are clean and dry and antiseize tape is clean,
(2)
Start antiseize tape one or two threads from small or leading edge of fitting, joining tape together
with an overlap of about 1/8 in. (3.18 mm) for fittings with fine threads. For fittings with coarse threads, tape should be
wrapped around threads two or three times.
(3) Tightly wrap antiseize tape in same
direction as you would tighten a nut. Tape must be
pressed into threads without cutting or ripping.
DO NOT exceed specified torque or use power
tools to tighten fittings taped with antiseize
tape. Overtightening could damage fitting
threads and cause connection to leak.
(4) Using hand tools, tighten fittings to
specified torque.
4-25. FLUID DISPOSAL.
Dispose of contaminated drained fluids in accordance with the Standard Operating Procedures (SOP) of
your unit.
