Recommended Practices

The development of Recommended Practices is the primary reason for the existence of TMC Study Groups and Task Forces. It is through the development of Recommended Practices that TMC provides technology solutions for the trucking industry.

The first Recommended Maintenance Practices Manual was unveiled in December 1973, and the first practice—RP 101, “Heavy Duty Alternator Mounting”—remains in the manual today, although it is now joined by more than 400 other recommended practices.

Your TMC membership provides you with access to our two-volume Recommended Practices (RP) Manual, which includes both the Recommended Maintenance Manual and Recommended Engineering Practices Manual, which helps members address the critical technology and maintenance issues that have the greatest impact on truck fleets. The Recommended Practices Manual is an unequaled reference for maintenance personnel, technicians, engineers and suppliers.

TMC’s Recommended Maintenance Practices are voluntary practices that assist equipment users, vehicle/component manufacturers and other industry suppliers in the maintenance of commercial vehicles.

TMC’s Recommended Engineering Practices are voluntary practices that assist equipment users, vehicle/component manufacturers and other industry suppliers in the design, specification, construction and performance of commercial vehicle equipment.

Q&A with Bob Allen, senior director, fleet maintenance, Hub Group

When Bobby Allen, senior director, fleet maintenance at Hub Group, received a maintenance call about one of the more than 66,000 power units he supervises, he automatically, reaches for one of several Technology & Maintenance Council's recommended maintenance practices.

There's no point in reinventing the wheel, he says. "Anytime a maintenance issue comes up, I reach for the appropriate RP that is never further than my laptop.  It's one of the many membership benefits of TMC," Allen says.  A long-time member of TMC, Allen believes the peer-reviewed research behind each RP gives him the benefit of the most comprehensive, accurate information he needs to make the best-informed equipment decisions.


I refer to RP 237A Torque Checking Guidelines for Disc Wheels and RP 169 Road Service Diagnostic Evaluation Service.
I use it to guide the driver through the safest, most effective procedures to perform during a road service call. It gives me a list of procedures for systematically conducting a proper diagnostic evaluation of the primary electrical system - batteries, starter, alternator, and cabling. Only after this process has been completed, should a service provider contact the equipment user or fleet for repair or replacement authorization.
I feel like this is the best most practical guide out there because the RPs are peer reviewed and backed by research including real world experience and comprehensive testing by various committees made up of maintenance directors and other industry professionals.
I've really had a chance to network with people I wold have never met. When i first became a director of maintenance, a former director said, "If you don't do anything else, now that you're a director you should be a member of TMC." I took his advice and really feel like the information presented at the meetings helps me stay current with technology changes. Plus, I take advantage of attending te committee meetings around subjects I'm interested in..
