    A combination of innovations working at the point of combustion, ACERT™ technology optimizes engine performance while meeting regulations for off-road applications.

    Cat C18 Tractor Engine

    The tractor for the 631G is powered by the C18 engine with ACERT™ Technology. The large displacement and high torque rise provide optimal performance in the load, cut, haul and return. Matched to the high efficiency torque converter and electronically controlled power shift transmission, it will provide years of dependable service.

    Cat C9 Scraper Engine

    The 637G has a C9 engine with ACERT technology which provides additional power to assist in loading as well as improved hauling performance on grades.

    Dual Horsepower

    Cat engines have dual horsepower capability with the low power setting in torque converter drive and the high power setting in direct drive. If the auger is engaged while the machine is in torque converter drive, the machine automatically goes to the high power setting.

    Mechanical Electronic Unit Injection (MEUI)

    The MEUI system with variable shaped injection patterns provides for optimum combustion based on altitude and temperature. The Cat MEUI fuel system is a highly evolved fuel system with a proven record of reliability in the field. The system combines the technical advancement of an electronic control system with the simplicity of direct mechanically controlled unit fuel injection pressure. These features allow the C18 to completely control injection timing, duration and pressure.

    Electronic Control Module

    The ECM responds to operator commands and engine sensor input to optimize engine and machine performance. This advanced engine management software controls and protects the engine at all times against cold starts, high altitude operations and air filter plugging by monitoring:

    • injection timing and pressure
    • engine cooling fan speed
    • ether starting aid
    • hydraulic pumps

    NGMR Engine Cooling System

    The standard radiator for the tractor is the Next Generation Modular Radiator (NGMR), which features 9 fins per inch rather than 33 fins per inch found on previous models. The increased radiator fin spacing for both the tractor and the scraper reduces clogging in severe applications. Two-piece service doors improve access to clean out debris.

    Extended Oil Change Interval

    Oil change intervals in the C18 engine can be extended to 500 hours with the use of S•O•SSM analysis.

    Scraper Bowl

    Designed for optimum loading, material retention and ejection.

    Material Application

    Well suited to handle a wide variety of material from clay to shot rock.

    Redesigned Bowl

    The redesigned bowl minimizes falling material lodging between the bowl and the draft arm, which can result in premature wear. The modifications also provide better load retention on level ground or traversing down a grade. Bowl capacity has been increased by 3 yd3 (2.3 m3), allowing more material to be moved.

    • Low-profile bowl design offers less resistance to incoming materials.
    • Cellular construction adds strength and dent resistance to bowl sides and floor.

    Bulldozer Ejection System

    Cat bulldozer ejection system offers constant spreading control with minimal material carry back. A spill guard helps retain material and keep it from spilling over onto the rear of the scraper (optional on single engine open bowl scrapers).

    Cutting Edges

    May be adjusted according to job conditions. The stinger (drop down) position provides good penetration and efficient flow of material into the bowl, whereas the level cutting edge is used for finish work or very high impact conditions.

    Push-Loading

    To achieve maximum productivity, the 631G should be push loaded by a D9R or D10R Track-Type Tractor. The larger tractor offers quicker loading times with denser loads than the smaller tractor.

    Power Train - Transmission

    Integrated electronics allow the machine to monitor the entire power train, reducing component stress and providing a better ride.

    Transmission

    Electronically controlled Caterpillar planetary powershift transmission with eight forward and one reverse speed. Tractor gears 1 & 2 operate in converter drive for increased torque capability during cut and fill operations. Gears 3-8 operate in direct-drive for drive train efficiency during the haul. All scraper gears operate in converter drive for increased torque capability during the cut and fill.

    Final Drives

    Outboard-mounted, planetary design final drives reduce torque loads on other power train components. Large-capacity, double-row roller bearings and Caterpillar Duo-Cone® seals deliver exceptional reliability in the toughest applications.

    Independent Brake Systems

    Expanding-shoe type brakes use a cam-operated design, which is air-applied and spring released. The secondary braking system uses independent front and rear circuits that are automatically applied if the service air pressure drops to 55 psi (380 kPa). Audible and visual action alert indicators inform the operator when the service air pressure drops to 75 psi (518 kPa).

    Steering

    Full hydraulic power steering provides automotive feel with positive, modulated flow control for constant steering response. An optional supplemental steering system is ground-driven and provides hydraulic power for steering if needed.

    Structures

    Superior structural design and construction optimize performance and reliability.

    Storage And Amenities

    Convenient storage location includes space for a lunch box and first aid kit. The cab also has a cup holder as well as an ashtray.

    Visibility

    The redesigned hood has sloped corners to maximize visibility while accommodating the low emissions engine. The redesigned hood and front shroud are wider to enclose the air-to-air aftercooler (ATAAC), ether starting aid, and lights. The exhaust is located at the back of the hood for good visibility to the right side.

    Instrument Display Panel

    Features a new quad-gauge layout showing engine coolant temp, transmission / torque converter oil temp, fuel level, and system air pressure.

    Engine Speed Lock Controller

    Enhances operation during long haul cycles by allowing the operator to maintain a desired engine speed without maintaining pressure on the throttle.

    Simplified Transmission Control

    Simplifies gear selection (1st, 2nd, Drive and Reverse) and allows operator-defined top gear control. Relocating the gear control to the rear increases operator legroom.

    Grab Handle / Hand Rest

    The grab handle/hand rest located next to the joystick controller helps operators when adjusting seat swivel, and gives them a place to rest their hand while on the haul and return roads.

    Single Lever Implement Control

    Simple and easy to operate, the joystick enhances the productivity of operators of all skill levels. Requires less force to control the critical scraper functions and requires less lever travel. 1) Bowl (forward & back) 2) Ejector (side to side) 3) Apron (thumb rocker switch) 4) Transmission Hold 5) Cushion Hitch 6) Rocker switch (not shown - is on front of joystick)

    • Auger (on/off)
    • Push-Pull (bail up/down)
    * Standard open bowl does not have a rocker switch.

    Electronic Controls

    Integrated electronic controls provide smooth, consistent shifts through the synchronization of engine and transmission speeds.

    Simplified System

    Improved Serviceability

    Combined monitoring systems, easy access diagnostics and more durable components make routine maintenance and servicing simple and fast.

    Product Link

    Product Link is a wireless system that allows the customer to track machine data such as location, service meter hours as well as machine health information. The system can automatically issue alerts when the machine is operated beyond owner-defined time and location limits. Product Link is available as a factory attachment or it may be installed in the field, in that there is a mounting location for the module as well as an antenna on the machine. A wiring breakout is standard, without having to splice into existing wires.

    Fuel Economy

    Electronic controls optimize the timing setting for varying conditions. The ADEM A4 controller matches timing to the load on the engine, engine rpm and temperature.

    Reduced Exhaust Smoke

    The ADEM A4 controller monitors electronic sensors to determine the optimum fuel/air ratio. Fuel is precisely controlled during cranking, starting and acceleration to reduce smoke. The Engine Electronics are faster and more efficient than mechanically controlling the governor rack position.

    Auger Arrangement

    Excellent self-loading capability in a wide range of material.

    Versatility

    The auger has a wide material appetite ranging from rock to free flowing material such as sand.

    Auger Mechanism

    The auger lifts material off of the cutting edge, conditions it and carries it to the top of the load for true self-loading capability. Material is distributed evenly throughout the bowl, resulting in consistent loads.

    Material Handling

    The auger actions on the material produce several benefits:

    • wide material appetite, ideal for landfills
    • blends the material to help eliminate voids in the bowl for consistent payloads
    • conditions material for precise metering and better compaction in the fill
    • reduces dust and noise during loading

    Optional Push-Pull Arrangement

    Caterpillar offers a self-loading arrangement for the 627G.

    Push-Pull Attachments

    This optional arrangement concentrates the combined horsepower of two machines onto one cutting edge. The push-pull attachments allow two individual machines to act as a self-loading system, typically loading both machines in less than a minute.

    Hydraulically Actuated Bail

    The push-pull arrangement uses a hydraulically actuated bail and cushioned plate bolted to the front of the tractor, and a hook that is attached to the rear of the scraper.

    Increased Production

    As the lead machine enters the cut, the trailing machine lowers the bail on the hook of the first machine. The second machine then pushes the first machine until it is loaded. When the second machine begins its loading cycle, the first machine pulls the second machine until it is loaded. After both machines are loaded, the second machine raises its bail and disengages from the first machine.

    Flexible Fleet

    This system provides a more balanced, flexible fleet using fewer machines and less investment than comparable self-loading or push-loading systems.

    Auger Arrangement

    Excellent self-loading capability in a wide range of material.

    Versatility

    The auger has a wide material appetite ranging from rock to free flowing material such as sand. The auger lifts material off of the cutting edge, conditions it, and spreads it evenly in the bowl for true self-loading capability.

    Material Conditioning

    As the auger carries material from the cutting edge to the top of the load, it conditions the material into uniform size which helps eliminate voids in the bowl, thus ensuring consistent payloads. Conditioned material also requires less compactive force in the fill. In applications where dust is a concern, the auger has demonstrated that it significantly minimizes dust while loading when compared to the elevator loading system.

    Dual Horsepower

    Tractor engine automatically reverts to the higher setting when the auger motor is engaged.

    Slip Limiter Switch

    Prevents rear wheel slip during loading.

    Single hydraulic system for entire machine with separate implement pumps/valves simplifies maintenance and improves reliability.

    Auger Benefits

    The auger actions on the material produce several benefits:

    • wide material appetite, ideal for landfills
    • blending material creates a consistent, well-mixed load
    • conditioned material reduces voids in the bowl for larger, more consistent payloads, and promotes compaction in the fill
    • reduces dust and noise during loading
    • precise metering of material in the fill

    Serviceability

    Count on Caterpillar for simplified service and the most productive uptime.

    Electronic Monitoring System (EMS III)

    Monitors machine status and provides real-time information to the operator including warnings of problems identified by the Electronic Control Modules.

    Implement Valve Relocation

    The implement valve has been relocated from the tractor to the top of scraper draft tube, reducing the number of hoses and tubes that cross over the gooseneck. The move reduces potential leak points, and improves service access.

    One Piece Power Block

    Jumpstart receptacle and disconnect switch are integrated into a one-piece power block for better electrical integrity and serviceability. The disconnect switch, with a lockable cover, disables all power from the batteries and jumpstart functions.

    Electro-Hydraulic Implement Control

    Simplifies serviceability by removing the cab pilot valve and associated lines, which also improves reliability and reduces noise. The high efficiency electro-hydraulic pilot oil filter provides cleaner oil for the pilot system.

    Scraper Electrical Harness

    A ribbon wiring harness replaced the cable harness for improved wear and durability. Its increased flexibility oscillates with the machine, and polyurethane boots offer better protection against the elements.
