Heavy Duty Tridem Axles for On/Off and
Off-Highway Operations.
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.
