Ideally suited for demanding vocational applications including construction, heavy haul, logging, oil field, and mining.
Features
Broad ratio coverage for optimum performance across a variety of vocations
Designed for greater strength to maximize durability and reliability in even the toughest applications, including:
Extra wide face-width primary and helical gearing
High capacity bearing and gearing systems
An integrated ring gear and wheel differential mounting system that eliminates bolted joints
Large wheel differential gearing
An integral pinion cage and carrier that also eliminates a potential leak path
Heat-treated steel differential cases for strength and wear resistance
Heavy wall housings
Dana patented exclusives include:
A threaded input adjuster that precisely sets end play in the power divider without the use of shims, eliminating a potential leak path and improving reliability
A hypoid gearing design that improves interaxle driveline angles to minimize vibration
An on-demand lube pump that reduces temperatures as much as ten percent, extending lubricant life and reducing internal friction and wear
Threaded differential bearings with integrated adjusters that maximize life by providing continuous adjustments and allowing precise settings of gears and bearings
Options include driver-controlled wheel differential lock for maximum traction over slippery, loose or uneven surfaces.
Available Options
Driver-controlled wheel differential lock for maximum traction. For T78-190P and T78-590P models, the wheel differential lock feature can be retrofitted even after the vehicle is built or in use.
Carrier integrated retarder mount means more drivetrain options with increased strength, brake performance, and reduced complexity.
Wide-track axles available for improved stability.
