Mainframe Strength – Built to Last

Helping you get more done with maximum availability, the D9T's durable design makes repair and maintenance easy. Customers can rebuild these tractors several times using the same frame with only minor repairs. With unparalleled support from Cat dealers it is not unusual for a Cat large dozer to log more than 100,000 hours.

The D9T mainframes are built to absorb high impact shock loads and twisting forces encountered during severe dozing and ripping applications.
The main case, equalizer bar saddle, and front cross member are heavy duty steel castings incorporated into highly loaded areas of the mainframe to improve stress distribution for improved durability.
Top and bottom rails are made from continuous rolled sections, providing superior mainframe durability.
The main case elevates the final drives well above the ground level work area to protect them from impact loads, abrasion and contaminants.
The pivot shaft and pinned equalizer bar maintain track roller frame alignment and allow the roller frame to oscillate for smoother ride.

Tag-Link

Tag-Link blade mounting brings the blade closer to the machine for excellent maneuverability, machine balance and blade penetration. This design also eliminates the need for diagonal bracing by transferring side loads to the mainframe, instead of the dozer push arms.

Equalizer Bar End Pins

Proper grease lubrication on working surfaces can significantly extend component life and help lower maintenance cost.

Remote lubrication is performed from a service point conveniently located on the left hand side of the engine compartment and allows an operator or service technician to lubricate both the left-hand and right-hand equalizer bar end pin bearings and pins from one service point.

C18 ACERT

Performing at full-rated net power of 306 kW (410 hp), the large displacement and high torque rise allow the D9T to rip through tough material. Matched to the high-efficiency torque converter and electronically controlled power shift transmission, it will provide years of reliable service.

ADEM™ A4 Engine Controller

Manages fuel delivery for optimal performance per liter (gallon) of fuel used. Provides flexible fuel mapping, allowing the engine to respond quickly to application needs. Tracks conditions and keeps engine operating at peak efficiency.
