TMC Updates VMRS
Licensing Program, Codes
By Jack Poster, TMC VMRS
Services Manager
TMC's Vehicle Maintenance Reporting
Standards (VMRS) is introducing a series of
changes and updates to the coding system
used by fleets, OEMs and service providers
involved in equipment maintenance.
The changes include adding additional
licenses bringing the total to four licensing
options that will broaden the scope of
VMRS users. The new licensing will include
an Electronic Catalog license designed for
parts manufacturers and distributors that
are interested in matching their parts with a
VMRS code for online/catalog use. For more
information, visit: https://bit.ly/35zEiuV
TMC has also updated its VMRS
Implementation Handbook, bringing it up-todate
to include the latest list of VMRS codes
and recently added Code Keys. The Handbook,
which is available in electronic and print format,
is an essential tool for those using VMRS, it also
serves as a great training tool and reference
guide for those that wish to learn more about
the proper method of implementing VMRS. For
more information, visit: https://bit.ly/3wEXd3v
TMC remains hard at work adding VMRS codes;
nearly 1,100 new codes have been added
during the Covid-19 lockdown. TMC is also
working with several major OEMs on adding
new codes for Electric Vehicles (EV) there are
currently more than 125 new EV codes in the
Code Key 33 data base with more being added
on a regular basis. VMRS staff has also been
working with fleets such as Altec Corporation
on developing new codes for hydraulic utility
vehicles. VMRS has always included codes
for utility equipment but having the professionals
at Altec lending their expertise to
the project adding new codes ensures the
codes will reflect the industry's needs.
VMRS has long been a mainstay for all
involved in equipment maintenance, the
new changes will ensure that VMRS will continue
to reflect any and all new equipment
technologies and will continue to be an
important part of equipment maintenance
for many years to come. For more information

that TMC has conducted the survey, giving the
members a comparison of year-to-year SRT data.
The survey is based on VMRS making it easier
to aggregate repair times. Data presented in this
report is based on the labor description and the
corresponding VMRS Code Keys for each task.
In the second report, which is available online,
repair and replacement of clutch assemblies and
automatic transmissions were reported to be the
most labor-intensive tasks followed by EGR cooler.
Replacement of the air brake compressor edged
out radiator replacement this year. For more information,

TMC Recommended Practices enter appeal period
The Technology & Maintenance Council (TMC) of the American Trucking Associations is proposing adoption of the following Recommended Practices.
* Proposed RP 170B(T), Chassis-To- Body
Electrical Interface Guidelines for Refuse
Trucks. This RP is to provide the refuse
industry a common electrical interface
connection that is environmentally sealed,
contains all required electrical circuits and is
located in an industry standardized location.
* Proposed RP 237C(T), Torque Checking
Guidelines for Hub Piloted Disc Wheels. This
RP is designed to help fleets develop practical,
fleet-specific guidelines for checking and
retorquing (if required) fastener torque on hubpiloted
disc wheels to support wheel system
integrity. This RP applies to disc wheels used
on Class 4-8 commercial vehicles.
* Proposed RP 252A(T), Troubleshooting Radial
Tire Irregular Wear. This RP offers guidelines
and a diagnostic process to identify the root
cause or causes of radial tire irregular wear
patterns that may develop during the useful life
of the tire. This RP applies to radial tires used
on Class 6-8 commercial vehicles.
* Proposed RP 256A(T), Inspection Criteria
for Steel and Aluminum Wheel Corrosion and
Pitting. This RP provides inspection criteria for
steel and aluminum wheel corrosion or pitting on
wheels used on Class 4-8 commercial vehicles.
* Proposed RP 257A(T), Measuring Wheel End
Assembly Runout. This RP is to provide fleets
and service providers with a procedure and list
of tools needed to check wheel end assembly
runout at a service location. This procedure
applies to steel or aluminum wheels used on
Class 4-8 commercial vehicles.
* Proposed RP 312C(T), Qualifying Questions
for Evaluating Aftermarket Diesel Fuel
Additive Packages. This RP is intended to
provide a list of questions fleet maintenance
managers should keep in mind when
considering the use of diesel fuel additives.
* Proposed RP 320E(T), Inspection, Maintenance
and Tension of Accessory Belt Drive Systems.
This RP provides fleet maintenance personnel
with correct procedures for inspecting and
maintaining accessory belt drive systems. This
RP also identifies factors which cause changes
in belt tension and defines the impact proper
maintenance procedures have upon drive
system performance.
* Proposed RP 326A(T), Selecting Quality
Recycled Engine Coolant. This RP offers
guidelines for selecting quality recycled engine
coolant/antifreeze. This RP applies to Class 7-8
diesel powered vehicles.
* Proposed RP 355B(T), Maintenance and
Inspection Guidelines for OEM-Installed
Exhaust Particulate Filters for DieselPowered
Vehicles. This RP describes the
various types of original equipment diesel
particulate filter (DPF) technology used
on heavy-duty diesel-powered vehicles. It
offers general guidelines and information
on DPF function, performance, diagnostics,
maintenance, handling and cleaning.
* Proposed RP 368A(T), Proper Coolant
Draining and Filling Procedures for HeavyDuty
Diesel Engines. This RP is to provide
general guidelines for properly draining and
filling heavy-duty diesel engines with coolant
as part of normal maintenance or after flushing
of the system due to a failure.
* Proposed RP 377(T), Managing Transition
to Lower Viscosity Engine Oils. This RP is
designed to help fleet managers decide how
best to transition fleets to American Petroleum
Institute (API) designated, lower viscosity
CK-4 and FA-4 engine oils. The RP applies to
diesel-powered Class 7 and 8 vehicles.
* Proposed RP 618C(T), Wheel Bearing
Adjustment Procedures for Conventional/
Manually Adjusted Wheel Ends. The purpose of
this RP is to achieve a verifiable wheel bearing
end play of 0.001 " to 0.005 " (0.025 mm to
0.127 mm). on conventional wheel ends that
are designed to be manually adjusted. It is not
applicable to pre-set or unitized wheel ends.
