TRIDEM DRIVES

Three new Dana Spicer tridem drive axles have been introduced by Dana Corporation’s Commercial Vehicle Systems group. The new tridem family is designed to reduce life-cycle costs and improve reliability while giving customers a complete range of application-specific axle options, the company says.

The new tridem axle line includes: the T69-170HP Series, rated up to 200,000 lb GCWR, suited for various vocational applications including construction, heavy haul, and logging; the T78-190P Series, rated up to 240,000 lb GCWR, designed to tackle oilfield and mining applications that often require superior traction and a high weight capacity; and the T78-590P Series, rated up to 240,000 lb GCWR, which is suited for those vocational applications requiring high GCWR capacities in combination with numerically high ratio availability.

Patented features include: an on-demand lube pump that reduces temperatures as much as 20%, extending lubricant life and reducing internal friction and wear; and a hypoid gearing design that improves interaxle driveline angles to minimize driveline vibration. A broad range of ratios is available to meet a variety of vocational applications, as is a wheel differential lock in all axle positions for maximum traction.

The three models, all of which carry a 3-year/350,000-mile warranty for most vocational applications, are now available for production orders on all makes and models of trucks and tractors manufactured in North America.
