2026 Kenworth T880

Category, Truck. Mixer application with 29,711 miles suggests light-to-moderate duty time, typical of early life vocational cycles with lots of PTO time and stop-and-go operation. Serial number 1NKZLK0X5TJ215054, stock number 0633129. Powertrain details are not provided, so engine family, transmission, axle ratio, and PTO configuration cannot be verified from the listing data. ECM status is not stated, so hours, idle percentage, fault history, and regen history should be pulled from the ECM before assigning a duty profile or maintenance interval. Frame rails and vocational mounting points are the areas that tell the story on a mixer, look for paint rub-through, bolt hole elongation, and any cracking around mixer pedestal mounts, rear crossmembers, and suspension hangers. Cooling stack condition matters in concrete work, check for packed fins and bent cores, plus CAC boot seepage and clamp witness marks. Cab entry points and interior touch surfaces should be checked for jobsite wear, door hinge sag, seat base play, and pedal pad wear that can indicate more hours than miles. Hydraulic and driveline interfaces deserve a close look, verify PTO engagement feel, driveline u-joint play, carrier bearing condition if equipped, and any wetness at PTO covers, pump fittings, and hose chafe points. Brake and tire wear should be read as a stop-and-go indicator, measure lining thickness, check for heat checking on drums or rotor surfaces depending on spec, and inspect steer tire shoulder wear for alignment and kingpin condition.
