On vehicles equipped with Detroit transmissions, the release bearing does not need to be lubricated. On vehicles equipped with Eaton Fuller UltraShift PLUS

transmissions, lubricate the release bearing every 50,000 miles (80 000 km) or 3 months.

†

Replace the clutch assembly for Detroit automated transmissions at 750,000-mile (1 200 000-km) intervals.

‡

For Schedule II vehicles with Detroit automated transmissions spec’d to haul more than 80,000 lb (36 000 kg), change the transmission fluid at 200,000-mile

(322 000-km) intervals.

For Eaton Fuller transmissions, fluid change intervals are extended to 500,000 miles (800 000 km) on vehicles filled with synthetic transmission fluid.

For Schedule I vehicles with Detroit axles, complete this procedure once a year or every 25,000 miles (40 000 km), whichever comes first.

If equipped with an oil-coalescing desiccant cartridge, replace the cartridge once a year, regardless of mileage. Otherwise use the M3 maintenance interval.

††

Complete this procedure every 25,000 miles (40 225 km), 3 months, or 500 operating hours, whichever comes first.

Noise Emission Control
Maintenance

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-control degradation throughout the
life of the vehicle. In compliance with the law, the
noise emission controls maintenance information in
each applicable group of this manual, in conjunction
with the vehicle workshop manual, provides these
instructions to owners.

Recommendations for
Replacement Parts

Replacement parts used for maintenance or repair of
noise emission controls should be genuine Freight-
liner parts. If other than genuine Freightliner parts
are used for replacement or repair of components
affecting noise emission control, the owner should be
sure that such parts are warranted by their manufac-
turer to be equivalent to genuine Freightliner parts in
performance and durability.

Freightliner Noise Emission
Controls Warranty

Refer to the vehicle owner’s warranty information
book for warranty information concerning noise emis-
sion controls.

Tampering with Noise Controls is
Prohibited

Federal law prohibits the following acts or the caus-
ing thereof:

The removal or rendering inoperative by any per-
son (other than for purposes of maintenance,
repair, or replacement) of any device or element
of design incorporated into any new vehicle for

the purpose of noise control, prior to its sale or
delivery to the ultimate purchaser, or while it is in
use.

The use of the vehicle after such device or ele-
ment of design has been removed or rendered
inoperative by any person.

Among those acts presumed to constitute tam-
pering are the acts listed below:

A. Removal of engine noise-deadening panels.

B. Removal of cab-tunnel or hood noise-

deadening panels.

C. Removal of, or rendering inoperative, the en-

gine speed governor so as to allow engine
speed to exceed manufacturer’s specifica-
tions.

D. Removal of, or rendering inoperative, the fan

clutch, including bypassing the control on
any thermostatic fan drive to cause it to op-
erate continuously.

E. Removal of the fan shroud.

Removal of, or rendering inoperative, ex-
haust components, including exhaust pipe
clamping.

G. Removal of air intake components.

Scheduled intervals are in the maintenance tables in
this group. A "Verification of Inspections Log" for
Groups 20 and 49 follows, and should be filled in
each time noise emission controls on the vehicle are
maintained or repaired.
