OPERATOR’SCOMPARTMENT
OPERATOR’SCOMPARTMENT
The walk-through operator’s compartment is
spacious and comfortable.Maximum productivity can only be
accomplished through the design of
an efficient operator’s compartment
and accurate, easy-to-use controls.
The D39 is designed to put the oper-
ator in control. The attention to detail
in positioning of controls, instrument
panel, and visibility of blade means
the operator can remain at high levels
of productivity while being less fatigued
as the day progresses.
● The suspension seat adjusts
to the operator’s weight for
maximum comfort.
● Armrests can be adjusted to provide
the best position for the individual
operator, ensuring operation of
controls without awkwardness
or fatigue.
● Gauges and warning lights are
positioned for at-a-glance viewing.
● Controls are easily reached
and operated.
● Visibility over the front of the
machine is excellent and the
operator can also see more
of either side of the blade.
Suspension Seat
Designed to adjust and compensate
for the size and weight of the operator.
Includes forward and rear adjustments
as well as featuring lumbar support for
lower back. Readily accessible seat
belts are kept in a storage holster
or are retractable.

Instrument P anel
Instrument panel is mounted at an
angle for easy view by the operator.
It provides a full complement of easy
to see and read analog gauges and
indicator lights.
Speed and Braking Contr ol
The right pedal combines engine
deceleration and primary machine
braking. It also supplies parking brake
function by depressing and engaging
the small floor-located brake lock. The
left pedal activates a spring-applied
secondary brake without decelerating
the engine speed.
ROPS Canop y
A four-post ROPS canopy is designed
specially for the D39. Extra length
over the front protects operator’s feet
from rain or snow. A special sound-
absorbing pad is mounted to the roof.
Lighting
Three halogen lights are included as
standard equipment. One is mounted
above the fuel tank and two are
mounted at the front of the ROPS
and protected by the roof overhang.

Easy to Learn Natural Controls Are StandardJoystic k Steering: The logical choice for providing smooth, precise control in
order to gain maximum productivity. Their operation mirrors the natural motion of
the activity the operator wishes to perform. For example:
T-Bar Blade Contr ol: Lift, tilt, and angle are controlled hydraulically by a
right-hand operator’s control. Provides precise grading efficiency. The blade
responds quickly by a slight move or twist of the low effort lever, giving the
operator a true feel for the blade.
Undercarriage
UNDERCARRIAGEAND FRAME
UNDERCARRIAGEAND FRAME
Sprockets
One-piece castings are bolted to the final-drive sprocket hubs and transmit the sprocket-tooth
load through the entire sprocket bolt pattern. Replacement can be made without removing the
entire track frame assembly or partial disassembly of the final drive.
Reduced Maintenance Requirements With Lubricated Track System
The track-chain elements include a patented seal assembly to keep pin and bushing surfaces
lubricated with oil. Internal pin and bushing wear are virtually eliminated. Track life is extended
and hourly undercarriage costs are reduced.
Top Idler s
For added reliability and durability, top idlers incorporate long-life, heavy-duty tapered
roller bearings.

D39E/P-1CRAWLER DOZER
FrameProven two-piece construction incorporating high-strength steel plate. Fenders
and ROPS mounts are part of the frame weldment.
Track Frame and Gaug e
The D39E/P track gauge is 62 inches. Track frame consists of high-strength
rolled steel side channels, welded together to form a rigid foundation.
Suspension System
The D39 suspension system is a rigid or non-oscillating type proven on thousands
of applications around the world.
Angling Frame and C-Frame
Designed to eliminate or reduce stress concentrations at all critical junctures. C-frame
is mounted to front undercarriage cross-beam tunnel for an easy alignment with the track
and main frames after any machine reassembly.
Durab le Blade
The moldboard is 90,000 psi yield material, providing high strength and excellent wear
resistance. The contact areas between the back of the blade and the angling frame provide
added durability due to the use of large contact areas and high-wear resistant, easily
replaceable wear plates.
Low-Maintenance BladeThere are only two lubrication points on the blade system. All cylinder pivot connections
are sealed and permanently lubricated, non-metallic bushings
and chrome-plated pins.
Blade Widths and Angling f or Travel
The blade width of the D39E is 8'10" and the width of the D39P is 9'3".Unique b ladeangling capabilityallo ws transpor t ofthe D39E within an8' width and theD39P within an8'6" width.

ENGINE ANDTORQUE CONVERTER
ENGINE ANDTORQUE CONVERTER
Komatsu S4D102E-1 Engine This turbocharged 239 in3 engine delivers 67 kW 90 HP @ 2200 rpm. Designed to be rugged,
provide outstanding power, excellent fuel consumption, easy to service, and highly reliable.
Meets current EPA Emission Standards.
Built to Be Rug ged and Reliab le
Features include an alloy cast iron, deep-
skirted block with main bearing supports
between each cylinder. Provides maximum
strength and rigidity, low weight, and
excellent crankshaft support.
Potential gasket problems are reduced and
high air flow efficiency is achieved through
a one-piece cross-flow cylinder head with
integral intake manifold.
Forged steel crankshaft is designed for
low stresses and high torsional stiffness.
Provides outstanding reliability.
Mounted on Resilient Engine Mounts
Mounts are located close to the roll center
of the engine, allowing natural vibrations
to dissipate, which reduces transmission
of vibrations to the crawler frame and
the operator.

Built f or Easy Ser vice and Long Lif e
Simple construction with fewer engine
components. The oil and water pump
housings, oil filter head, and alternator
mountings are incorporated into the
block, reducing potential leak points
and allowing faster rebuilding.
● Engine block is rebuildable, cylinder
walls can be rebored twice.
● Oversized pistons and rings
are available.
● Dry sleeves available for engine
rebuilds after the first two.
The torque converter is attached
directly to the flywheel housing of
the engine, providing easy access
for servicing without removal of
the transmission.
Smoother Operation
Komatsu torque converter allows the
operator to throttle down so he can
finely control track speed while still
providing good hydraulic flow to the
dozer blade. Helps operator perform
complicated tasks with greater ease
because torque converter:
● Absorbs shocks
● Multiplies engine torque
● Reduces engine lugging
● Eliminates need for a clutch
● Provides better control of power
Transmission
Provides three forward and three
reverse speeds and is mounted directly
to the front wall of the rear main frame.
Excellent Load Capacity
Helical cut gears are in constant
mesh and are hydraulically selected
by a pilot valve located in the shift
tower. The pilot valve signals the
main transmission control valve that
activates the selected clutch pack.
The simple, reliable pilot control
system replaces the need for complex
transmission control linkages or
push-pull cables.
Smooth Shifting
Rate of oil flow is automatically
controlled, providing smooth, low
shock shifting. Provides less shock
to the power train and good dozing
results with the blade.
Easy Ser vice
The modular location in front of
the rear main frame provides good
service access.
Counter shaft Design Reduces Costs
Countershaft designs use up to one-
third fewer components than competi-
tive planetary designs, reducing the
time and expense of rebuilding.
Unique Long-wearingClutc h/Brake System
Provides excellent steering modula-
tion over any range of quick or broad
steering. Provides smooth, non-jerky
steering. The steering clutches and
brakes are caliper/disc-type of the same
design principle found in the automotive
industry. Cooling and lubrication are
achieved by immersing in oil.
Advantages of disc brakes include:
● Longer life
● Lack of fade
● Lower maintenance because of
partial self-adjustment capabilities
● Consistent operation
Final Drives
Housed in modular cast housings.
Final drives employ a pinion and bull
gear speed reduction to increase
torque for high drawbar pull.
