CP 663 E Caterpillar CP 663 E Specifications & Technical Data (2001—2007)

Reliability, Serviceability and Comfort in a Durable Package

The CS-663E, CP-663E and CS-683E Soil Compactors have been designed to offer enhanced production capabilities, simplified service and exceptional operator comfort.

Setting industry standards... again.

Based upon the industry-proven reputation of the Caterpillar D-Series Soil Compactors, the new E-Series establishes new standards for productivity, comfort and serviceability in the soil compaction industry.

Vibratory System

Pod-style weight housings ensure peak vibratory performance and minimal service. Pods are replaceable and feature bearing lubrication change intervals of 3 years/3000 hours. The pod-style weight system, proven reliable on D-Series Soil Compactors, delivers superior compactive force while offering serviceability advantages.

Tires

with wheel loader design tread 20.5 R25, radial (L-2), 12-ply tubeless for smooth drum machines and offers enhanced durability in harsh applications.

Turbocharged Engine Features

Turbocharged-Air-to-Air Aftercooled for top performance and efficiency especially at high altitudes – up to 2500 meters without derating. Direct injection-rotary fuel pump provides accurate fuel delivery. Highly-efficient combustion chamber increases power while lowering fuel consumption, engine emissions and noise. Low cylinder pressure rise and low peak pressure provide outstanding reliability and durability. Large oil cooler reduces oil deterioration and varnishing of internal parts. Low-mounted oil pump for quicker start-up lubrication. Meets all known current worldwide engine emissions standards. Thermal starting aid is standard.

Engine

Four-stroke cycle, six cylinder Caterpillar® 3056 ATAAC turbocharged low emissions diesel engine. Net power advertised is the power available at the flywheel when the engine is equipped with fan, air cleaner, muffler and alternator. No derating required up to 2500 m altitude. Above ratings apply at 2200 rpm when tested under the specified standard conditions.

Instrumentation

Alternator Light, Hour Meter, Fuel Gauge, Horn, Audible Warning Horn for the: Engine Oil Pressure Light, Engine Coolant Temperature Light, Hydraulic Oil Temperature Light, Low Charge Pressure Light.

Steering

A priority-demand hydraulic power-assist steering system provides smooth low-effort steering. The system always receives the power it needs regardless of other hydraulic functions.

Frame

Fabricated from heavy gauged steel plate and rolled sections and joined to the drum yoke at the articulation pivot. Articulation is structurally reinforced and joined by hardened steel pins. Two vertical pins provide a steering angle of ± 34° and a horizontal pin allows frame oscillation of ± 15°. Sealed-for-life hitch bearings never need greasing or shimming.

Final Drives and Axle

Final drive is hydrostatic with gear reducer to the drum and hydrostatic with differential and planetary gear reduction to each wheel.

Brakes

Service brake features Closed-loop hydrostatic drive system provides dynamic braking during operation. Secondary brake features* Spring-applied/hydraulically-released multiple disc type brake mounted on the drum drive gear reducer and within the rear axle. Secondary brakes are activated by: a button on the operator’s console; loss of hydraulic pressure in the brake circuit; or when the engine is shut down. A brake interlock system helps prevent driving through the secondary brake. * Braking system meets EN500-1995.

Transmission

Two variable displacement piston pumps supply pressurized flow to two dual displacement piston motors. One pump and motor drives the drum propel system while the other pump and motor drives the rear wheels. The two-pump system ensures equal flow to the drive motors regardless of the operating conditions. In case the drum or wheels lose traction, the other motor can still build additional pressure to provide added torque. The drive motors have two swashplate positions allowing operation at either maximum torque for compaction and gradeability or greater speed for moving around the job site. A toggle switch at the operators console triggers an electric over hydraulic control to change speed ranges.

Electrical

The 24-volt electrical system consists of two maintenance-free Cat batteries, color-coded and numbered wiring wrapped in nylon braid. The starting system provides 750 cold cranking amps (cca). The system includes a 55-amp alternator.

Vibratory Tachometer

The vibratory tachometer is mounted on the console in front of the operator and displays the actual vibratory system frequency. This feature is most useful when ordering the variable frequency option.

Variable Frequency

The variable frequency is an electronic displacement control on the vibratory pump that is controlled by a frequency dial on the operator’s station. Engine rpm remains unchanged for maximum hydraulic pump flow and torque to drive the vibratory motor. The frequency range from 23.3-30 Hz makes it easier to match frequency, amplitude, and working speed to job conditions.

Padded Drum Conversion Kit

The padded drum conversion kit (CS-663E only) is interchangeable with the smooth drum. Two options are available. The first option includes all drum components including hydraulic motor, brackets, gear and support boxes, shell, mounts, brackets and pods, front bumper, and scrapers. The second option includes minimal drum components such as the shell, drive plate, front bumper, and scraper. Padded drum dimensions and performance are the same as on the CP-663E.

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.

Operator’s Station

Based on the successful Cat G-Series Wheel Loader operator’s station, the E-Series Soil Compactors feature excellent operator comfort and visibility. A tilting steering column, propel lever wrist rest, grouped control gauges and conveniently located control switches enhance operator productivity and reduce fatigue. Four heavy-duty isolation mounts provide a smooth ride. Single lever control for propel and vibratory On/Off provides simple and low effort operation. Padded adjustable wrist rest helps reduce operator fatigue. Steering console and operational gauges are infinitely adjustable within the tilt range to the desired position of the operator. Entire console tilts for simple entrance and exit. Full-length glass windshield provides exceptional visibility to the drum and articulation area. Comfortable and durable seat is fully adjustable to include fore/aft position, bottom cushion height, suspension stiffness and flip-up arm rests. A five position-rotating seat is standard on machines equipped with a cab. Isolated operator’s station with four heavy-duty rubber mounts reduce machine vibration transmitted to the operator.

ROPS/FOPS Cab

includes a cloth seat that rotates to five positions, one access door, tinted safety glass windows, electric wipers front and rear, heater/defroster, two vertically sliding side windows for ventilation, two exterior rear view mirrors, two front and two rear working lights, interior dome light and coat hook. Cab is fully ROPS rated and meets ISO 3449-1992 and ISO 3471-1994.

Rear View Mirrors

are available for internal use on machines equipped with a ROPS/FOPS cab or external use on machines equipped with a ROPS/FOPS canopy.

Working Light Package

for machines equipped with a ROPS/FOPS canopy. Illuminates immediate work area under dim or dark conditions. Consists of two front and two rear flood lights. This system is intended for use under working conditions and not for highway transport purposes.

Rotating Beacon

includes an amber beacon and mount that can be attached to machines with ROPS/FOPS canopy or ROPS/FOPS cab.
