The Cat D9T has a reputation for outstanding productivity, operator comfort, and robust
reliability. It is a highly versatile machine flexible enough to be used in heavy construction,
quarries, landfills, forestry, and mine sites.
Cat customers can count on the D9Ts continued legacy of superior performance,
longlife, ease of operation and world-class service from the global Catdealer network
to be the backbone of their operation.
3
Mainframe Strength Built to Last
Helping you get more done with maximum availability, the D9Ts 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
than100,000 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.

Engine and Emissions Technology
6
Cooling System
Superior cooling keeps you moving in the mostdemanding work conditions.
The D9T provides durable, efficient cooling for the most demanding
conditions encountered on job sites.
Air-to-Air Aftercooling
Air-to-air aftercooling on the D9T cools hot, compressed air coming
out of the turbocharger providing cooler and denser air for the air
intake system. Bringing more cool air into the engine increases
power generation, lowers emissions, andimproves fuel efficiency.
Attachments
Reversing cooling fan for heavy debris applications with ultra
lowspeed for cold weather.
7
Power Train
Power and control to efficiently moveyourmaterial.
8
The D9T power train design optimizes performance and the ease of
operation helps customers get more done for the lowest cost per unit.
Bi-directional Shift
This convenience feature helps reduce operator work load during
operation. Bi-directional shift allows the operator, by just making
adirectional change, to automatically select the desired forward
and reverse gears or the desired forward and reverse speeds
whenEASis activated.
Auto Downshift
This feature adds value by enhancing safety and productivity during
the dozing cycle. When not in EAS mode, auto downshift can be
used to automatically downshift the transmission when significant
load increases are detected, but this feature will not automatically
up-shift when load is reduced. Auto downshift provides optimal
performance with minimal operator effort. The operator may
override these automatic shift features at any time.
9
Undercarriage
Designed for optimized machine balance
andbestperformance at your site.
The elevated sprocket and fully suspended undercarriage work together, increasing traction
while creating a smoother ride for your operators. The elevated sprocket design transfers
implement shock loads to the mainframe, so final drives, axles and steering components
are isolated from harsh impacts. These benefits translate into higher production and longer
component life.
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
lessslippage, better balance, and a smoother ride.
Roller frames are tubular to resist bending and twisting, with added reinforcement where
operating loads are highest.
The undercarriage idler guard provides additional wear protection from abrasive material
to the moving undercarriage. Includes rubber idler protectors.
Positive Pin Retention (PPR) sealed and lubricated track is designed for high-impact
andhigh load applications. The Caterpillar design locks the link to the pin reducing the
opportunity for premature loss of lubrication. Sealed design permanently coats the track
pin with lubricant, minimizing metal-to-metal contact and virtually eliminating internal pin
and bushing wear.
10
Work Tools
Provide flexibility to match
themachine to your job.
Bulldozers
All blades feature a strong box-section design that resists twisting
and cracking. Blades are made of high tensile strength steel that
stands up to the most demanding applications.
High-Capacity Universal Blades Offers optimal capacity
formoving big loads over long distances.
Semi-Universal Blades Built for tough applications where
penetration is important.
Cutting Edges and End Bits Cutting edges are made of
DH-2steel. End bits are made of DH-3 steel for maximum
service life. For extremely severe applications, moldboard wear
plates, extended wear life end bits and cutting edges are available.
Dual Tilt (optional) Improves load control and allows the operator
to optimize blade pitch angle.
Cat Work Tools offer a range of special application blades,
including coal stockpile blade, landfill blade, cushion dozer blade,
reclamation blades and wood chip blade.
Rippers
Rippers are made to penetrate tough material fast and rip thoroughly
for use in a variety of materials.
Single-Shank Ripper Built for the tough ripping conditions and
greater ripping depth. Operator can adjust the shank depth from
the seat using an optional single-shank pin puller. Large one piece
shank, available in deep rip configuration.
Multi-Shank Ripper Generally for lighter duty ripping applications
in less severe materials. Provides high levels of productivity.
Tailorsthe tractor to the material by using one, two or three shanks.
Rear Counterweights
Rear counterweights provide proper tractor balance to maximize
dozing production. Recommended if dozer is not equipped with any
other rear attachment.
11
Operator Station
Designed for your comfort,
convenience,andproductivity.
12
The D9Ts cab design provides ergonomic controls, intuitive monitoring
systems, and enhanced visibility. All of the new features within the D9T
operator station provide an industry leading operator environment that
helps contribute to high levels productivity, efficiency, and comfort.
Comfortable Operation
Standard machine provides 76 dB(A) for North America operator noise
levels. Lower sound levels are available if optional sound suppression
packages are installed.
Cat Optimized Seat has six way adjustment control for optimal support
and comfort. Seat side bolsters restrain side-to-side movement,
especially when working on side slopes.
The tapered hood, notched fuel tank, and narrow ripper carriage gives
the operator a clear line of sight to front and rear work areas.
Information Display
The multi-color/touch screen display located at the front of the right
hand console is the operators gateway to monitoring machine
performance and a convenient way of modifying machine parameters
to tailor performance to the current task.
13
Integrated Technologies

Ok-to-Start
The Ok-to-Start strategy provides electronic fluid level verification at startup
on the engine coolant, engine oil and power train oil systems. All information
isavailable via the Information Display within the cab.
VIMS 3G
This system gathers historical trends, histograms, events and more through
awired connection for off-board analysis in applications such as VIMS PC.
Additional subscription is required.
15
Seat Belt Warning System
This feature reminds the operator toengage the seat belt anytime the key
is on (LCD icon). If the operator still does not engage the seat belt and
places the machine in gear a chirping sound will be initiated.
Anchorage Points
On the D9T, anchorage points provide your people with a positioning
system to perform repairs and maintenance. The D9T consist of
eight (8) total anchorage points.
