D9T Track-Type Tractor

Strength from the past. Power for the future.™ The D9T combines power and efficiency with

advanced technology for outstanding production at a lower cost-per-yard.

C18 Engine with ACERT ® Technology

Operator Station

Implement and Steering Controls

✔

ACERT Technology works at the point

of combustion to optimize engine

performance and provide low exhaust

emissions. Matched with the torque

converter and power shift transmission,

it provides years of dependable and

efficient service. pg. 4

✔

Designed for operator comfort,

convenience, and productivity.

Machine control and vital information

is provided at the operator’s fingertips.

A full day of work is no problem in this

efficient work place. pg. 6

✔

Electro-hydraulic implement controls

allow low operator effort for dozing and

ripping. Steering and gear selection in a

one-hand control system enhances

operator comfort. pg. 8

Work Tools

Serviceability and Customer Support

Various bulldozer blades, rippers,

winches, and other options allow you

to adapt the D9T to match your specific

application, making you more

productive. pg. 12

✔

Combining easy to access, modular

components with your Caterpillar ®

Dealer’s advanced rebuild and repair

capabilities ensures rapid component

replacement and minimum downtime.

pg. 13

Engineered for demanding work.

The durable construction of the D9T is

well suited for tough working conditions.

Combined with the C18 engine for superior

performance, fuel economy and meeting

emission targets with the help of ACERT

Technology, it keeps material moving with

the reliability and low operating costs you

expect from Cat ® tractors.

Drive Train

Undercarriage

Structure

The electronically controlled power

shift transmission, efficient differential

steering and durable planetary final

drives deliver outstanding power transfer

and long life to ensure maximum

productivity. pg. 9

The proven elevated sprocket

undercarriage isolates the drive train

components from ground-induced

impacts. The suspended undercarriage

puts more track on the ground for

higher traction and less track slip.

It absorbs shocks for a smoother ride

and longer machine life. pg. 10

Mainframe is heavy, strong and durable.

Full box sections, steel castings and

continuous rolled rails provide durable

support to the suspended undercarriage,

elevated final drives and other integral

frame components. pg. 11

✔ New Feature

C18 Engine with ACERT ® Technology

A combination of innovations working at the point of combustion, ACERT Technology

optimizes engine performance while meeting EPA Tier 3 and EU Stage IIIa engine exhaust

emission regulations for off-road applications.

Overhead Cam. Gears drive an overhead

cam on the front end of the engine.

To reduce wear, a pendulum absorber

is mounted at the front of the camshaft.

These features contribute to the long-life

and durability of this engine.

ADEM™ A4 Engine Controller.

The ADEM A4 electronic control

module manages fuel delivery to get

the best performance per gallon (liter)

of fuel used. It provides flexible fuel

mapping, allowing the engine to respond

quickly to varying application needs.

It tracks engine and machine conditions

while keeping the engine operating at

peak efficiency.

C18 Engine. Performing at full-rated net

power of 306 kW (410 hp) at 1,800 rpm,

the large displacement and high torque

rise allow the D9T to doze through

tough material. Matched to the high

efficiency torque converter and

electronically controlled power shift

transmission, it will provide years of

dependable service.

C18 Block. The one-piece, grey iron

block features generous ribbing for

stiffness and heavy bearing bulkheads

for rigidity and strength. Incorporation

of straight o-ring connection points

reduces the loss of engine oil and fluids.

Fuel Delivery. Multiple injection fuel

delivery involves a high degree of

precision. Precisely shaping the

combustion cycle lowers combustion

chamber temperatures, generating

fewer emissions and optimizing fuel

combustion; translating into more work

output for your fuel cost.

More Complete Fuel Combustion.

High cylinder pressures combined with

tightly controlled tolerances promote

extremely efficient fuel burn, less blow

by, and lower emissions.

MEUI Fuel System. A highly evolved

fuel system with a proven record of

reliability in the field. MEUI combines

the technical advancement of an

electronic control system with the

simplicity of direct mechanically

controlled unit fuel injection. The MEUI

system excels in its ability to control

injection pressure over the entire engine

operating speed range. These features

allow the C18 to have complete

control over injection timing, duration,

and pressure.

ATAAC and Airflow. Air-to-air

aftercooling keeps air intake temperatures

down and, in concert with the tight

tolerance combustion chamber

components, maximizes fuel efficiency

and minimizes emissions. Significant

improvements in air flow are generated

by a water-cooled turbocharger,

unique cross-flow head and a single

overhead cam.

Service. Easier maintenance and repair

through monitoring key functions and

logging critical indicators. Electronic

diagnostic access is possible with a

single tool, the Cat Electronic Technician.

Turbocharging and Air-to-Air

Aftercooling. Provides high horsepower

with faster response time while keeping

intake temperatures low for long hours

of continuous operation.
