International introduced its trucks and tractors under the PayStar name in the late 1970s to fit in with the company’s Transtar, Fleetstar, Loadstar and Cargostar truck lines. Several of International’s most respected severe service vehicles carried the moniker until 1998, when they were re-named the 5000 Series. These included the 5500, 5600, and 5900.
“We have a number of customers who still refer to our 5000 Series trucks as PayStar long after we removed the badging,” said Bill Sixsmith, marketing director for International’s severe service vehicle center. “The International PayStar name is what the customers want to see on the sides of their trucks.”
The new International PayStar lightweight mixer packages, unveiled at this year’s World of Concrete show in Las Vegas, feature a lighter weight design that allows customers to haul more payload and still meet federal bridge formula limits, the company said.
The PayStar 5500′s lightweight design and 12-inch frame allows customers to haul 10 yards of concrete legally, a 7.5 percent payload increase over the previous design, the company said. The 5600 model can haul 11 yards legally, a 6.8 percent increase in payload capacity.
The new PayStar is lighter primarily because of the new 330-hp Cummins ISL engine.
The PayStar won’t be International’s only “Star” truck. International will unveil its new 2007 Class 8 tractor, ProStar, in March at the Mid-America Trucking Show in Louisville, Ky.
Cummins Unveils 2007 ISL for Vocationals
Cummins introduced its 2007 ISL for the vocational market Jan. 17 at the World of Concrete trade show in Las Vegas.
The new model adds cooled exhaust gas recirculation technology and an integrated Cummins particulate filter to meet the 2007 emissions standards.
The engine will also feature a simple crankcase ventilation management system to eliminate oil carryover from the engine, Cummins said. The average vocational truck will need to replace the low-cost Enviroguard coalescing filter at every third oil change, the company said.
“The ISL has the lightest weight of any engine in its class and is available with peak horsepower up to 365 hp,” said Chuck Goode, Cummins specialty markets director.
The engine boasts 1250 pounds-feet of torque, Cummins said.
A new option allows mixer operators to monitor the engine oil level from inside the cab, eliminating the need for daily manual inspection, Cummins said.
The engine also features an enhanced High Pressure Common Rail fuel system, which delivers higher injection pressures for lower emissions and will continue to feature the variable geometry turbocharger, which adjusts airflow to increase vehicle performance. Fuel efficiency is increased while maintenance intervals remain unchanged, Cummins said.
Hours Rule in Court The Owner-Operator Independent Drivers Association has filed a court challenge requesting review of the new hours-of-service regulations for truck drivers.
