Clear the Air: Don’t be sidelined by a failing air compressor

TORONTO, Ont. -- Admit it. A truck’s air system probably isn't your most pressing maintenance concern. The systems are pretty reliable, and beyond changing the air-dryer desiccant cartridge every couple of years, you probably don't give the rest of the system any more attention than it absolutely needs. While its primary function is supplying air for the brake system -- an important task in its own right -- other components on the truck need air, too. Automated transmissions, for example, and certain emissions system components.

Final mile introducing new maintenance demands

ATLANTA, Ga. – Evolving delivery models are leading to a new generation of vehicles as fleets look for new ways to serve the all-important final mile of e-commerce orders. Against the backdrop of dense urban centers that are demanding an end to emissions, the trucks and vans are also more likely than ever to be electric. “The economics of those are starting to become positive in some applications,” said Thomas Dollmeyer, Cummins’ director of electrification technology, during a panel at the annual meeting of the Technology and Maintenance Council. Electric urban buses are already economically viable, while the same could be said about electric Class 4-7 distribution vehicles as early as 2020, he said. But changes like that will lead to new challenges on the shop floor.
