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.
