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.
