General Information
Federal Law, Part 205: Transportation
Equipment Noise Emission Controls
Part 205, Transportation Equipment Noise Emission
Controls, requires the vehicle manufacturer to fur-
nish, with each new vehicle, such written instructions
for the proper maintenance, use, and repair of the
vehicle by the ultimate purchaser to provide reason-
able assurance of the elimination or minimization of
noise emission degradation throughout the life of the
vehicle. In compliance with the law, the noise emis-
sion controls maintenance information located in
each applicable group of this manual, in conjunction
with the vehicle workshop manual, provides these
instructions to owners.
Normal Vehicle Use
The maintenance instructions contained in this
manual are based on average vehicle use and nor-
mal operating conditions. Unusual vehicle operating
conditions may require service at more frequent in-
tervals.
Recommendations for Replacement
Parts
Replacement parts used for maintenance or repair of
noise emission controls should be genuine Freight-
liner Custom Chassis Corporation (FCCC) parts. If
other than genuine FCCC parts are used for replace-
ment or repair of components affecting noise emis-
sion control, the owner should be sure that such
parts are warranted by their manufacturer to be
equivalent to genuine FCCC parts in performance
and durability.
Freightliner Noise Emissions Warranty
See the vehicle owner’s warranty information book
for warranty information concerning noise emission
controls.
Tampering With the Noise Controls is
Prohibited
Federal law prohibits the following acts or the caus-
ing thereof: (1) the removal or rendering inoperative
by any person other than for purposes of mainte-
nance, repair, or replacement, of any device or ele-
ment of design incorporated into any new vehicle for
the purpose of noise control prior to its sale or deliv-
ery to the ultimate purchaser or while it is in use, or
(2) the use of the vehicle after such device or ele-
ment of design has been removed or rendered inop-
erative by any person. Among those acts presumed
to constitute tampering are the acts listed below:
A. Removal of engine noise-deadening panels.
B. Removal of, or rendering inoperative, the engine
speed governor so as to allow engine speed to
exceed manufacturer’s specifications.
C. Removal of, or rendering inoperative, the fan
clutch, including by-passing the control on any
thermostatic fan drive to cause it to operate con-
tinuously.
D. Removal of the fan shroud.
E. Removal of, or rendering inoperative, exhaust
system components, including exhaust pipe
clamping.
F.
Removal of air intake components.
G. Removal of hood liners (noise-deadening pan-
els).
Maintenance Instructions
Scheduled intervals are in the maintenance table in
this Group. A "Verification of Inspections Log" follows,
and should be filled in each time the noise emission
controls on the vehicle are maintained or repaired.
