FEATURES & BENEFITS

Engineered for maximum production and service life.

Mainframe Strength

Helping you get more done with maximum availability, the durable design of the mainframe makes repair and maintenance easy. The D11T/D11T CD mainframes are built to absorb high impact shock loads and twisting forces during severe dozing and ripping applications. It is not uncommon to see these machines rebuilt several times using the same frame, with only minor welding.Frame rails have a full box section design which keeps components rigidly aligned.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 which provide 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.Heavy cast saddle has a ribbed design which increases frame life.Tag-link blade mounting brings the blade closer to the machine for excellent maneuverability, machine balance and blade penetration.

Equalizer Bar End Pins

Proper grease lubrication on working surfaces can significantly extend component life and help lower maintenance cost.The remote lubrication for the D11T/D11T CD is performed from a service point conveniently located on the left hand fender 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.Adding the optional autolube system allows the operator to tailor the amount of grease needed for each application by volume and service interval.

Carrydozer Frame

The Carrydozer frame is specifically designed to accept the additional frame loads generated by the unique Carrydozer blade design.

Power and control to efficiently move your material.

Torque Divider

The Cat D11T/D11T CD use a torque divider between the engine and the transmission to act as the hydrodynamic component, reducing the possibility of damage to the power train by dampening impact loads and vibrations.A single-stage torque converter with output torque divider sends 75 percent of engine torque through the converter and 25 percent through a direct drive shaft for greater driveline efficiency, higher torque multiplication, and ease of operation.

Planetary Powershift Transmission

Three speeds forward and three speeds reverse, utilizing large diameter, high-capacity, oil-cooled clutches.Modulation system permits smooth speed and direction changes.Modular transmission and bevel gear slide into rear case for easy servicing, even with ripper installed.Oil-to-water cooler for maximum cooling capacity.Forced oil flow lubricates and cools clutch packs to provide maximum clutch life.Controlled throttle shifting regulates engine speed during directional shifts for smoother operation and longer component life.

Steering Clutch and Brake

Fade resistant and adjustment free. The multi-disc, oil cooled steering clutches are hydraulically applied and electronically controlled. The brakes are applied by springs and hydraulically released for safe and reliable braking performance. Steering clutches, brakes and final drives can be removed as a unit from each side of the tractor.

Designed for optimized machine balance and performance at your site.

The elevated sprocket and suspended undercarriage work together, increasing traction and giving the operator a smoother ride. These benefits translate into higher production and longer component life. This design transfers implement shock loads to the mainframe, so final drives, axles, and steering components are isolated from harsh impact loads commonly seen in large track-type tractor applications.Bogie suspension allows the track to conform to ground condition, providing up to 15% more ground contact, especially in hard, uneven terrain. Higher traction means less slippage, better balance, and a smoother ride.Integrated carrier roller mount is fabricated into the track roller frame making it easy to add the optional carrier roller in the field.Rollers and idlers feature symmetric Duo-Cone™ seals for long sealing life to prevent oil loss and dirt entry.Roller frames are tubular to resist bending and twisting, with added reinforcement.Sleeve bearing track is a unique track link assembly that maximizes life and minimizes downtime. It is designed to operate at higher speeds and greater loads.Sprocket segments have four bolt-on replaceable rim segments of abrasion resistant tough steel for long wear life.Track master link with single tooth and coarse thread bolts provide superior reliability and durability.
