CS-423E Soil Compactor
The CS-423E Soil Compactor provides high compaction performance in the most
cost-effective way. Designed for efficiency, while minimizing operating costs, the CS-423E
features a Caterpillar
®
3054C engine rated at 62 kW (83 hp). The CS-423E will meet your
smooth drum compaction needs in the majority of applications.
Gradeability and Machine Control
The exclusive dual pump propel system
provides a separate balanced hydraulic
flow to both the rear drive axle and the
front drum drive motor. This system
enables the operator to achieve
unmatched gradeability and maintain
machine control while compacting on a
grade or using the optional leveling
blade. Dual pumps also minimize drum
and wheel spin-out in low traction
conditions.

Vibratory System
A pod-style weight housing ensures
peak vibratory performance and
minimal service. The pod is replaceable
and features bearing lubrication change
intervals of 3 years/3000 hours.

Productivity and reliability you can depend on.
Durable, field-proven powertrain and vibratory systems
along with the world’s largest and most dedicated dealer
support system ensure the 400E-Series Soil Compactors
will provide maximum utilization. With exceptional
productivity and reliability, the 400E-Series Soil
Compactors provide everything you expect from a
Caterpillar machine and more!
Operator’s Station
The 400E-Series Soil Compactors
feature exceptional operator comfort
and visibility. A propel lever wrist rest,
grouped control gauges and
conveniently located control switches
enhance operator productivity and
reduce operator fatigue. Four heavyduty isolation mounts provide a smooth
ride. Standard rearview mirrors, two
front-facing and two rear-facing
working lights are provided. Machines
with the open ROPS/FOPS platform are
surrounded by handrails and features
foot rests for sure footing when
working on a grade.

Versatility
An optional two-piece padfoot
conversion kit (for the CS models only)
expands the application range to work
in either cohesive or semi-cohesive
materials. Simple changing procedure
minimizes your conversion time.

An optional foot-controlled leveling
blade for the CS-433E and CP-433E
increases machine utilization to tackle
backfilling, material knockdown and
light dozing applications.

Visibility
The one-piece sloped hood design
provides exceptional operator visibility
to the outside edge of the rear tires and
to the rear of the machine.

Cab
The cab on the 400E-Series Soil
Compactors is engineered to provide
the operator unparalleled viewing area
and comfort. Integrated, factory
installed air conditioning is optional.
The cab may be an option in some
areas and standard in others. Consult
your dealer for specifics.

Comfort and serviceability you deserve.
The operator’s station provides a spacious and comfortable work environment that allows
simple and productive operation. Excellent service access and long service intervals
minimize maintenance time and increase productive work time.
Serviceability
The one-piece fiberglass hood tilts
forward to allow access to the engine
and daily maintenance points. Daily
check points are accessible from ground
level. Sealed-for-life bearings in the
articulation hitch never need to be
greased. The operator’s station tilts
forward to provide access to the
hydraulic pumps. The engine
lubrication change interval is 500 hours.

CS-433E and CP-433E Soil Compactors
The CS-433E and CP-433E Soil Compactors provide maximum productivity and versatility
for both smooth and padfoot drum applications. Powered by the turbocharged, 75 kW
(100 hp) Caterpillar 3054C engine, these machines provide exceptional compaction
performance in demanding applications.

Vibratory System
The pod-style vibratory system delivers superior compactive force while offering
serviceability advantages.
Pod-style weight housing is assembled
and sealed at the factory to ensure
cleanliness, longer bearing life and
easier field exchange or service.
Dual amplitude works efficiently in a
wider range of applications. Selection is
controlled from the operator’s station.
Vibratory frequency of 31.9 Hz (1914
vpm) for maximum compaction results.
Optional variable frequency control
allows frequency to be better matched
to varying job conditions.
Large heavy-duty bearings for the
eccentric weight shaft designed for high
compactive forces.
3 year/3000 hour vibratory bearing lube
service interval reduces maintenance.
Heavy-duty isolation mounts allow more
force to be transmitted to the ground and
less vibration to the drum yoke.
Proprietary Eccentric Weights
Reliable dual amplitude selection and innovative design ensure precise performance.
Positive amplitude selection is
accomplished when the steel shot is
repositioned inside the hollow eccentric
weight. Direction of weight shaft
rotation determines amplitude level.
Simplified control from the operator’s
station with a selection switch on the
operator’s console.
High reliability since there is no chance
of the high-strength spherical steel shot
wedging together. System reliability is
superior to swinging mechanical
weights and is also quieter during starts
and stops.
Long service life. No heavy weights to
slam together, no metal fragments to
contaminate the bearing lubrication
system.

Caterpillar 3054C Series Diesel Engine
High-tech four cylinder engine provides outstanding durability, performance, reliability and
operating economy.
Dual Pump Propel System
High tractive effort and gradeability for outstanding productivity and machine control in
demanding environments.
The CS-433E and CP-433E are
turbocharged for top performance and
efficiency even at high altitudes with no
derating required up to 3000 m (9840 ft).
The CS-423E is naturally aspirated.
Adjustment-free direct injection fuel
system provides individually metered
high-pressure, direct injection of fuel
for maximum efficiency.
Large engine oil cooler reduces oil
deterioration and varnishing of internal
components. Allows for 500 hour
engine oil change intervals.
Low-mounted oil pump for quicker
start-up lubrication.
Combination fuel filter and water
separator offers superior protection for
the fuel injection system.
Engine meets U.S. EPA Tier 2 and
European EU Stage II emissions control
standards worldwide.
Dual propel pumps provide separate,
balanced hydraulic flow to the rear
wheel axle and the drum drive motors.
Provides high gradeability and
increases tractive effort in loose or poor
underfoot conditions.
Limited slip differential provides
balanced tractive effort and smooth
torque transfer to both rear wheels.
Two speed ranges for versatile
operation. Low speed range for
vibratory operation and maximum
torque when climbing grades. High
speed range moves machine quickly
over longer distances.
Flushing valves in each propel circuit
help keep hydraulic oil cool and clean
for maximum system efficiency.
