Diesel particulate filter (DPF) regeneration has long been a challenge for mechanics, and the maintenance staff at Brecksville-Broadview Heights City School District in Brecksville, Ohio, was no different.

“We would have buses [that needed to be regenerated] in front and in back of the garage, and it’s time-consuming because you have to plug them into the laptop and do the program for the regen,” says James Flauto, the vehicle maintenance foreman for the district. “You also have to watch them because sometimes [during] a regen it will set another code for another problem, and sometimes they fail the regen.”

The district’s transportation department runs 47 school buses that travel a total of 3,300 miles daily with a maintenance staff of four: two full-time mechanics, one part-time mechanic, and Flauto. To keep the buses running at optimal performance and transporting about 2,300 students daily, it takes a strong sense of teamwork within the small group.

“I stress a team effort around here,” Flauto says. “That way, we learn as a team, and I think it pays off every time.”


That team effort also applies to problem-solving. Over the years, the transportation department’s 29 buses that are 2010 or more recent models had frequent regeneration incidents. After talking to their Cummins representative, the team learned about a solution in Cummins INSITE that involves adjusting the parameters in the engine control module (ECM). The diesel particulate filter temperature stabilization, or “Stay Warm” feature, allows a little fuel to leak into the system, enabling aftertreatment, Flauto says.

The team tried out the fix in August, just before the school year started, and has since been able to reduce their buses’ regeneration incidents by over 80%.

“Some buses used to regen three, four times a week,” Flauto explains. “Of the buses that are regen-capable, I am seeing probably two a week, and it used to be five a day. Now we can spend time doing our job [instead of] plugging in computers. It really has helped.”

He adds that the solution is especially helpful for the district’s special-needs buses, since they idle a lot more than the general-education buses, making them more likely to regen.

Sharing the Solution

After they had a solution in hand, the team decided to share it with other technicians. Also known for his graphic design skills, Bart Hahn, one of the full-time mechanics, designed a one-sheet after the team outlined the solution instructions. In addition to sharing it with members of the Ohio School Bus Mechanics Association, Flauto says he also “gave it to anyone I could.”

“Information to make your job easier? I’m all about that,” he adds. “It’s all on one piece of paper, and the directions are very user-friendly.”

When Flauto attended a recent seminar held by the state association, an instructor from Cummins gave the instructional sheet positive feedback, and Flauto passed it out to attendees.

Other mechanics have also been appreciative, Flauto says.

“I have gotten calls from other mechanics, saying, ‘This is the greatest thing since sliced bread.’”

Proactive Maintenance

The Brecksville-Broadview shop team also prides itself on its rigorous preventive maintenance practices. The main procedure that the mechanics have put into place involves three inspections for every bus: an “A” inspection, a “B” inspection, and a “C” inspection.

The “A” inspection, which is conducted once a month, involves checking the entire bus, including the interior and exterior, for any issues or potential issues, and making repairs or replacing parts as needed. The “B” inspection is conducted once every six months, and includes everything covered in the “A” inspection, with the addition of an oil change. Once a year, a “C” inspection occurs. That includes all the aspects of the “A” and “B” inspections, and changing every filter on the bus, including the air filter, transmission filter, and fuel filters.

The maintenance shop also was able to reduce engine and transmission failures with the use of synthetic engine oil and transmission oil, and in recent years has switched the lights on the buses to LEDs for a significant budget and labor savings, Flauto says.

He adds that full-time mechanic Hahn’s work has been crucial to running the shop smoothly.

“He is a true asset to the shop, as well as to the transportation department as a whole,” Flauto says. “He deserves much of the credit around here.”
