Professional Technician Development Committee Information Report 2018-1: Determining Technician Entry-Level Skills
This information report presents the results of the Professional Technical Development Com- mittee’s (PTDC) Task Force on Determining Necessary Entry Level Technician Skills. The charge of this Task Force was to examine means of determining these essential skill sets tobecome a qualified applicant for technician positions in the industry.
S.3 Engine Study Group Information Report 2018-02: TMC Engine Performance Study
TMC’s “EPA 2007/2010 Engine Report Card” results were based on data from 23 fleets representing 157,541 power units of the U.S. trucking industry. Of these Class 7 and 8 power units, 24 percent were equipped with EPA 2010 engines, 29 percent were equipped with EPA 2007 engines, and 30 percent were equipped with EPA 2004 engines. The survey was administered in November and December 2011 and sent to more than 600 fleets whose representatives held membership in TMC as Fleet Executive level members.
S.14 Study Group Information Report 2016-1: Battery Electric Vehicles in Light- & Medium-Duty and Specialty Truck Commercial Applications
A Class 1-6 commercial motor vehicle (CMV) powered solely by electricity is much different than a CMV powered by an internal combustion engine (ICE) or by hybrid electric vehicle (HEV) design. A battery electric vehicle (BEV) design includes storage only for its onboard battery capacity, not fossil fuel. The battery capacity has a direct impact on vehicle range and powered features. The electrical propulsion system requires a high voltage supply andsignificant current draw that dictates the capability and therefore the battery capacity.
S.3 Engine Study Group Information Report 2015-1: Evaluation, Specification, Deployment and Maintenance Considerations for Natural Gas Powered Heavy-Duty Commercial Vehicles
Natural gas fuels can be a suitable alternative to diesel fuel for commercial vehicles in certain environments and applications. However, it is best to understand all facets of the operation, discuss them both internally and with local vendors (where applicable), and to establish re- alistic return-on-investment targets up front. Taking the time to build a proper business case and understand all the variables that come into play will pay dividends in terms of ensuringa successful natural gas vehicles deployment that meets corporate financial, reliability andacceptance expectations.
The purpose of this Recommended Practice (RP) is to provide information for judging the performance of aftermarket brake linings on air-actuated foundation brakes, including testing in accordance with the dynamometer test procedure in Federal Motor Vehicle Safety Standard (FMVSS) 121 and lining supplierqualification information. Such information will assist fleet operators in choosing aftermarket brake liningsthat will perform adequately on typical combination (tractor/trailer) vehicles and single trucks.
S.4 Cab & Controls Study Group Information Report 2013-1: Mirror Obscuration During Inclement Weather
Equipment users have reported to TMC experiences of mirror obscuration during inclementweather. Testing has confirmed cab and mirror design contributes to the concentrated flow of air that can contain water borne dirt. Large windshield wipers sweep significant fluid off the windshield and into the air flow path of the mirror heads, resulting in dirt deposits on the mirror surface. TMC has determined that a generic field fix cannot be developed since the causal factors are different for each manufacturer’s vehicle design.
S.5 Fleet Maintenance Management Study Group Information Report 2012-1: Addressing the Risk Posed by Counterfeit Parts in Fleet Maintenance Operations
As with many sectors of the U.S. economy, counterfeit parts have found their way into thetrucking industry. While the exact cost to the trucking industry is difficult to determine, it is estimated that counterfeiting represents a $12 billion per year problem for the entire automotive industry. Beyond just the monetary costs are the added safety concerns of these counterfeitproducts. For example, a single counterfeit brake valve can significantly decrease the overallperformance of a truck’s brake system.
The Performance Review Institute (PRI) has released an updated list of products reviewed by its Brake Lining Review Committee.The committee verifies the brakelinings have met test criteria established in TMC RP 628B and agrees with the specification data submitted by the manufacturer.
Service Provider Committee Information Report: 2011-1: Understanding Heavy-Duty Vehicle Standard Repair Time (SRT) Guides
This TMC Information Report provides equipment managers insight into how “Standard Repair Time” (SRT) guides are developed and used in support of equipment maintenance and repair. Equipment managers should recognize that SRT guides used by service providers vary for avariety reasons, such as corporate policy and affiliation, and access to specific SRT guides.
Professional Technician Development Committee Information Report: 2010-1: The Matriculation Process: A Proven Pathway for New Technician Success in the Workplace
Most fleets use a thoughtful approach in the hiring of technicians. However, many of these same companies take a minimalist approach to matriculation. This can lead to poor performance, unacceptable conduct issues and poor employee retention. The purpose of this document is to help fleet managers ensure that all newly hired graduates of technical trade schools make a successful transition to the next level of their career objectives.
