Kalamazoo, Mich., June 22, 2006 – Dana Corporation’s Commercial Vehicle Systems group is developing a new technology that promises to improve the overall efficiency of its Spicer® drive axle lineup by better controlling the flow of lubrication. Based on field and lab testing, the improvements are expected to reduce the negative effects of energy-consuming gear churning by as much as 20 percent.

This new technology has been developed around an innovative insert, protected by United States Patent number 6,938,731, that directs lubrication to areas in the axle where it is needed most, while controlling flow around the ring gear. The controlled flow minimizes churning energy losses while maintaining proper component lubrication. It will also reduce the amount of lubrication needed at factory and service fill points, thereby reducing costs. The initial design reduced required lubrication volume by six pints. An additional benefit includes reduced sump temperatures, resulting in increased film thickness that enhances gear and bearing life. These benefits are achieved with the added advantage of a slight reduction in overall system weight.

“We expect that this technology will be available to OEMs concurrent with the introduction of 2007 diesel engines,” said Leo Wenstrup, senior product manager – drive axles for Dana. “That’s important in that we see these developments as one way to help fleets mitigate higher anticipated operating costs.”

All testing and engineering work is being conducted with Roadranger® 75W-90 Synthetic Lubricant, which has proven to yield efficiency improvements with this new technology.
