The Technology & Maintenance Council took a “deep dive into emissions aftertreatment system maintenance” during their annual meeting in Nashville, Tenn., on Tuesday.
Panelists discussed the various ways they tackle aftertreatment maintenance issues.
“We always check gasket, clamps, bellows, and the EGR systems,” said Bryan Stewart, of Jones Logistics. “With the EGR system you can look for soot.”
“We implemented a smoke detection system to look for leaks and that has worked well.”
Stewart said his company developed oil analysis standards to get a snapshot of where his fleets are. He said soot levels can be an EGR valve or DPF filter stopping up and he always wants a TBN of no less than 3.5.
Stewart said his techs make filter changes at 100,000 mile intervals.
“We are constantly preaching to the drivers about cleanliness.”
