INTRODUCTION
This manual is provided to every user of a newly manufactured LUFKIN trailer to acquaint you
with the importance of maintenance and safety in the operation of your trailer.
The life of a trailer can be increased with adequate regular service and an organized Trailer
Preventative Maintenance program (TPM). The Department of Transportation requires by
regulation that maintenance records be kept on every commercial highway vehicle. It is to your
advantage to be able to show that regularly scheduled TPM inspection checks have been
performed on every piece of equipment operated and will place you in the most favorable
position from a legal standpoint in the event of an accident involving your equipment.
If LUFKIN can be of help in your Trailer Preventative Maintenance program, please give us a
call.
LUFKIN INDUSTRIES, INC.
IMPORTANT NOTICE
Vehicles manufactured by LUFKIN INDUSTRIES, INC., are designed to be operated in
accordance with the gross axle weight rating (GAWR) shown on the certification label and at
legal highway speeds in the service for which they were intended.
GENERAL INFORMATION
Maintenance should be performed by a LUFKIN Dealer or by other qualified service facilities
that regularly provide such service.
Alterations to a LUFKIN Trailer should not be made without first consulting the LUFKIN Trailer
Engineering Department. Alterations could affect the structural integrity of the trailer and void
the warranty. Welding or other alterations should never be made to any air reservoir, wheel,
rim, air chamber, or spring.
The gross axle weight rating (GAWR) that is stamped on the certification plate is the structural
capacity of the lowest rated component of the suspension, springs, hubs, drums, wheels, rims,
bearings, brakes, axles, or tires.
If components are substituted that affect GAWR that are of less capacity that those originally
installed, the GAWR on the certification plate must be lowered to the corresponding lower
capacity by adding an “Altered Vehicle” label. If components are substituted that are of equal
or greater capacity than those originally installed, then GAWR labels need not be changed.
Appearance maintenance is important to the Trucking Industry. It can favorably project the
public image of your company. It also adds to their physical condition and ultimate trade-in
value.
Protective films such as paints and other coatings are necessary to prevent corrosion and
protect the metal and wood surfaces. Trailers that operate in environments that are conducive
to severe corrosion may require more or different protective coatings than those usually
applied as standard; check with your LUFKIN representative for recommendations.
There are “WARNING” and “CAUTION” decals prominently displayed on all trailers. All
personnel operating the vehicle should follow these.

REPORTING SAFETY DEFECTS
If you believe that your vehicle has a defect, which could cause a crash or could cause injury or death,
you should immediately inform the National Highway Traffic Safety Administration (NHTSA) in addition
to notifying LUFKIN Trailers warranty or engineering departments at the numbers below.
If NHTSA receives similar complaints, it may open an investigation, and if it finds that a safety defect
exists in a group of vehicles, it may order a recall and remedy campaign. However, NHTSA cannot
become involved in individual problems between you, your dealer, or LUFKIN Trailers.
To contact NHTSA, you may either call the Auto Safety Hotline toll-free at 1-888-327-4236 (TTY: 1-800-
424-9153) or write to National Highway Traffic Safety Administration, 400 Seventh Street, SW,
Washington D.C. 20590; or go to http://www.safercar.gov. You can also obtain other information about
motor vehicle safety from the Hotline.
Upon request we will furnish any additional or more detailed maintenance and operational instructions
including any non-standard make of equipment that was specified and installed.
The following numbers are in Lufkin, Texas at the main office and manufacturing plant. Please contact
your factory branch or dealer first:

SECTION 1
1.1 SUSPENSIONS
1.1.1 TORQUE VALUES
The suspension is the assembly that connects the axles to the trailer frame and absorbs shock
loads and braking loads through the leaf springs or air springs (air bags). It is therefore important
that it be maintained.
The life of the suspension depends upon keeping the connections tight. These bolts can become
loose from vibration and shock and, if not properly maintained at recommended torque, will shorten
the life of the suspension, reduce tire life, and eventual failure of the suspension, which could cause
a serious accident.
The following suspensions are standard on LUFKIN Trailers and the torque given must be
maintained at the recommended intervals as well as the periodic inspections as listed.
All fasteners on the suspension of your new LUFKIN Trailer were torqued before delivery to the
proper torque values. Due to vibration and shock loads it is necessary after a break-in period of
1000 miles or three months, and every six (6) months thereafter, to tighten all nuts and bolts to the
recommended torque. Always check the torque on the nut and not on the head of the bolt. Do not
lubricate the threads unless values given are for lubricated threads.

1.1.2 AIR SPRING SUSPENSION INFORMATION
Regular preventive maintenance checks on air spring suspensions are the same as on leaf spring
suspensions with the addition of the air bags and air components. With the air pressure above 65
psi, the height between axle and frame should be within 1/4” of the same height at all air bags. If
not, it may be an indication of air loss at one or more air bags, air leaks at fittings, or malfunctioning
leveling valves. Leveling valves should have proper clearance to permit leveling arm to actuate
freely and not be bent or twisted. Do not grease leveling valves. There is a time delay of 2 to 6
seconds before the leveling valve will add or exhaust air to the air springs. The proper position of
the valve actuating lever is in the center or neutral. Lever up will add air; lever down will exhaust air.
Check leveling valve lever for being in proper position while trailer is connected to tractor in drive
away condition.
In the event of failure in one or more air springs, it is recommended the height control valve linkage
