Parts By Number: VMRS Codes
By Deborah Lockridge, Editor, and Jim Beach, Contributing Editor
Back in the late '60s, some people in the trucking business got together and decided to come up with a system that used numbers to describe parts and maintenance activities - a system that could cut through the mistakes made when using the written word to describe parts and maintenance activities. That system, the Vehicle Maintenance Reporting Standard, or VMRS, was unveiled in 1970 by the Technology and Maintenance Council of the American Trucking Associations. About 10 years ago, an updated version perfect for today's computerized systems was unveiled: VMRS 2000. The system is becoming more widely accepted today, and is spreading beyond the fleets it originally was designed for - including to parts and service providers.
The system was designed to provide a "universal translator for communicating from the shop floor to the people in charge of the money," says Jack Poster, VMRS services manager for TMC.
VMRS is also used to facilitate communications between fleets, OEMs and parts suppliers on warranty claims. And it offers independent parts distributors and service providers opportunities to share a common "language" with their fleet customers.
"Our fleet team encounters requests from their fleet customers all the time about having VMRS labels on product," notes Pat Biermann, president of Heavy Duty America. "We see this as an advantage to sell product."
Universal translator
Part of the problem with parts is that part numbers are so frequently superceded - often each year. VMRS serves as a "universal translator" that can be used to map various part numbers back to the unchanging VMRS component code.
"It's sort of like when Star Trek's Captain Kirk would travel around the universe, he always could speak English to the various alien life forms he encountered," explains Robert Braswell, TMC's technical director. "VMRS translates a cacophony of numbers and descriptions into a standard descriptor for each part covered." For instance, you might call an ABS tone ring a tooth wheel or an exciter ring, he explains. In VMRS, it's always 025-001-176 (Ring - Exciter, Transfer Case).
And it's not just for fleets.
"VMRS helps repair facilities improve maintenance management for their customers or their own fleets by providing a way to extract consistent data from repair orders," says Paul Reynolds, product architect at Karmak, which uses VMRS codes to help track parts in its software for distributors. "It brings order and efficiency to the complicated process of communicating and analyzing activities in the shop."
Linking the VMRS information to repairs performed allows the user to analyze what types of repairs they are performing, what type and manufacturer of unit is being repaired, the parts that were used in the repair, detail of what was performed on the repair, what are repairs costing, what interval are repairs being performed, and a lot of other valuable information, Reynolds notes. "That information can help managers measure technician productivity, control parts inventory, improve the effectiveness of a preventive maintenance program, and make budget decisions."
How it works
VMRS is a series of codes used to describe virtually every facet of the maintenance operation, from parts to manufacturers to technician work to vehicle location. Currently there are 64 main codes in VMRS, but "the heart of the system is Code 33," Poster says, which describes each part using a numerical system. At first, Code 33 was a six-number digit, but was increased to nine numbers with the VMRS 2000 release. Currently, there are more than 25,000 parts listed in Code 33, from antennae on a Loran system to a battery for a cargo sensor.
Code 33 starts out with three numbers describing the system, followed by three numbers that describe the assembly and three that describe the component.
Poster says the easiest example is brakes. Brake systems are 013. The next three numbers refer to the assembly: 001 refers to front brakes, 002 refers to back brakes. The final three numbers are the component; for instance, a brake shoe is 014. So the VMRS number for a front brake shoe would be 013-001-014. There are 101 different parts related to the front brake assembly from a variety of sources. Since most manufacturers use different part numbers systems and may even use different names for the same part, using the VMRS system cuts across brands.
Other key codes used by fleets include Code 1, equipment location, and Code 2, equipment category, to keep track of the vehicles. Code 5 is used to track the power source. Cab type is another code.
Another important one is Code 34, a five-letter alpha code to track brand name and where the parts were bought. This can be used in conjunction with the Code 33 parts description to monitor parts costs. For example, if a fleet gets brake components from Bendix, that can be coded into Code 34. TMC also can work with users to add a unique code describing which parts store a part comes from.
Another code used often by fleets is Code 14, reason for repair. For example, a breakdown would be 01. A routine inspection would be 05. Another code describes the work done; you can record if a part is replaced, repaired or inspected. There are codes for towing, parts fabrication and other functions.
Code 18 includes about 100 different ways for the technician to describe why the part failed, including no failure, battered, hammered, broken, cracked or out of balance parts.
If a shop's technicians are doing work other than repairing vehicles, such as washing vehicles or organizing the parts room, that work can be tracked using Code 36, which records indirect labor.
Results
The end result of using the codes for a maintenance shop, whether it's at a fleet or an independent service provider, is better control of maintenance costs and productivity. You can generate reports on any number of parts, from tiny light bulbs to the largest systems on the vehicle.
A number of shops organize their parts room according to VMRS numbers. As parts are received, they get a bar code label that includes the VMRS code. When technicians need a part, they scan the bar code and the code. Shop managers can pull reports that tell them what part that technician is using, on which vehicle it's being used, why the technician is using the part, what the part cost is, who made it and where it was purchased.
Such a setup "makes it a lot easier on the technicians," Poster says. "When I was a mechanic, I hated to have to spend time writing things down. If you can scan a bar code on the part, you don't have to write anything down."
VMRS is included in most maintenance software packages, in some cases as an optional module.
If a user finds they have some unique parts or equipment that is not included in the VMRS, they or their software vendor can call Poster and ask that codes for those pieces of equipment be included. For instance, Poster says he received a call from the city of Ottawa requesting codes for the articulated joint in their city buses.
"That's another unknown secret within the industry," Poster says. "People don't realize that with a phone call or e-mail to me, it is something that is easily done - updating the codes."
Poster works with a VMRS committee within the TMC to monitor the codes. "I get their opinions on possible new codes," he says. "With the committee feedback and feedback from users, VMRS is a very democratic process."
Growing standard
When VMRS 2000 was rolled out, the system was used mostly by large fleets and manufacturers. That's changing.
"It is being used by more fleets," Poster says, of all sizes. And the types of companies calling about the system are changing. "I'm getting a lot of calls from utility companies and government agencies who want to be able to track their equipment maintenance using the system." Other companies inquiring about VMRS include repair shops and other maintenance vendors serving trucking customers.
Aftermarket suppliers also have a strong interest in VMRS, not only because their fleet customers use it, but also because it helps facilitate parts management and fulfillment. HDX Services, for example, uses VMRS in its e-commerce parts management solution for aftermarket parts suppliers.
Some fleets may not even realize they're using VMRS, because many maintenance software packages use the system. "Fleet use is growing because of the advent of software for maintenance," Poster says. Software companies purchase a developer's license from TMC to embed the VMRS coding within their product. "Virtually every software vendor in this area will offer VMRS as part of their system. It may be an option, but most offer it."
In fact, Arsenault Associates, the makers of Dossier fleet maintenance software, reported at the TMC meeting earlier this year that its Dossier software was directly responsible for the introduction and implementation of VMRS in more than 60 percent of its new, big-fleet customers.
FleetNet America, a third-party maintenance company, this year announced it had expanded its use of VMRS, allowing it to apply costs to emergency roadside and preventive maintenance events more precisely across all vehicle types. Customers will benefit through more detailed analysis of their maintenance costs, especially as FleetNet America can electronically feed the information to a company's maintenance software.
"VMRS is the proven standard for fleet maintenance providers, regardless of size or area of expertise," says Oren Summer, president and CEO of FleetNet America.
The Decisiv Service Management Platform now supports VMRS, as well. This system, which helps service writers, automatically codes many standard operations, and service writers can also assign VMRS codes for non-standard operations.
The TMC's VMRS committee is also pushing manufacturers to make more use of the codes, according to Lew Flowers, manager, national fleet sales, for HD America and chairman of the committee.
One company that is using them is Tectran USA, which makes air, hydraulic and electrical components. "Tectran has all these little fittings in little bags," Flowers says, that can be a nightmare to deal with in the parts room. But using VMRS Code 34, which is the code key that is set up for manufactured brands, they can label all those little bags accordingly, making it easy for a parts stockers and technicians to scan them, stock them, and track them.
As a result of all this additional interest, the system continues to grow, with an average of about 600 updates made each quarter. Recent additions to the system include emissions and aftertreatment-related components, as well as parts found on utility and municipal trucks such as aerial lifts, post-hole diggers and other such components.
While non-traditional trucking fleets require new codes, most of the VMRS updating comes from advances in technology. Recent codes have been added for things such as vehicle tracking and communications equipment and emission control technologies. Other systems added recently include visual assist, the newer auxiliary power units, lane departure systems, diesel exhaust fluid and diesel particulate filters.
