CP-683E Caterpillar CP-683E Specifications & Technical Data (2003—2026)

Engine

Cat 3056E turbocharged electronic diesel engine delivers 129 kW (173 hp) and is built for performance and reliability without sacrificing fuel economy.

Caterpillar® 3056E Turbocharged Electronic Diesel Engine

Industry-proven Caterpillar technology designed to provide unmatched performance, reliability and fuel economy with ample power for the most demanding jobs.

Turbocharged air-to-air aftercooling

provides improved fuel economy by packing cooler, denser air into cylinders for more complete combustion of fuel and lower emissions.

Electronic Control Module (ECM)

provides improved emissions and optimal performance through electronic timing and fuel delivery along with advanced troubleshooting and diagnostic capabilities using Electronic Technician (Cat ET).

Electrical

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

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 SAE J1472 and EN 500.

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. Minimum turning radius: Inside 3.68 m (12' 1") Outside 5.81 m (19' 1") Steering angle: (each direction) ± 34° Oscillation angle: (each direction) ± 15° Hydraulic system: Two 76 mm (3") bore, double-acting cylinders powered by a gear-type pump.

Vibratory System

Pod-style eccentric weights ensure peak compaction performance and minimal service. High dynamic force helps achieve density in the fewest number of passes.

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. Rear mounted cooling system allows easy access for cleaning. The hydraulic oil cooler tilts down for convenient access and easier cleaning. Steps to the operator’s platform swing-out for easier access to hydraulic components and oil filters. The operator’s platform tilts forward to provide convenient access to the hydraulic components. Vibratory bearing lube service interval of 3 year/3000 hour keeps maintenance to a minimum and maximizes production. The articulation hitch area features sealed-for-life bearings that never need maintenance.

Pod-style weight housings

are assembled and sealed at the factory to ensure cleanliness, longer bearing life and easier field exchange or service.

Positive amplitude selection

is accomplished when the steel shot is repositioned inside the hollow eccentric weight. Direction of weight shaft rotation determines amplitude level.

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.

One-piece lockable engine hood

opens quickly and easily with the use of gas struts to provide unrestricted access to the engine, cooling system and all service points.

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.

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. To the tire edges and rear of the machine, visibility is exceptional. The sloped hood allows the operator to see obstacles measuring 1 meter (3’ 3”) high located 1 meter (3’ 3”) to the rear of the machine. Excellent visibility increases productivity when working near obstructions or maneuvering around the job site.

Operator’s Station

The 600E-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. Standard rearview mirrors, two front-facing and two rear-facing working lights are provided. New steering wheel with integrated center horn function and steering knob helps reduce operator fatigue.

Comfort and Serviceability

The operator’s station provides a comfortable and easy-to-use environment that promotes productive operation. Simplified service access and extended service intervals minimize maintenance time and increase productive work time.

Dual Amplitude

Works efficiently in a wider range of applications. High or low amplitude is selected from the operator’s station.

Steering Console and Instrumentation Gauges

Are infinitely adjustable within the tilt range to the desired position of the operator. The entire console tilts for simple entrance and exit.

Comfortable and Durable Seat

Has adjustable fore/aft position, bottom cushion height, suspension stiffness and flip-up arm rests with a 76 mm (3”) wide retractable seat belt.

Reliability and Serviceability

The 600E-Series Soil Compactors continue to provide exceptional reliability and serviceability that you’ve come to expect from Caterpillar.
