The C9 has a smaller physical envelope as well, weighing less than the 3306 with the additional benefit of all daily inspection points are located on the right hand side. |
|
ACERT Technology
ACERT Technology reduces emissions during the combustion process by using advanced technology in the air and fuel systems, in conjunction with integrated electronics.
ACERT Technology is a series of Caterpillar innovations that work at the point of combustion to optimize engine performance. It is sometimes easier to think of ACERT as a series of building blocks used by Caterpillar to optimize engine performance while meeting U.S. EPA Tier 3 and European Union Stage IIIa regulations. |
|
Record of Reliable Durability
ACERT Technology has been proving itself in on-highway trucks since March of 2003. It is technology that allows Cat engines to meet durability and reliability expectations – without sacrificing performance. Technologies used by other manufacturers, e.g. EGR, reintroduce dirty, corrosive exhaust gases back into the combustion chamber, leaving too many questions unanswered about engine life as well as shortened service intervals. Instead, Caterpillar chose a path of research and development on its existing technologies to arrive at a solution that uses fuel mapping, electronic control and multiple injection fuel delivery to manage emissions. The result is an engine that meets customer's reliability and durability expectations, as well as positioning Caterpillar engines to meet future regulations. |
|
Four Components
The building blocks of ACERT™ Technology are:
- Fuel delivery
- Electronic control
- Air management
- After treatment (on-highway only)
The three building blocks incorporated onto wheel tractor-scraper engines are fuel delivery through EUI (electronic unit injection), electronic control from the Cat ADEM A4 controller, and air management through cross flow design of the intake manifold and turbo charging. After treatment, the fourth building block or tool, is not needed on off-road applications at this time. |
|
ACERT Technology - Fuel Delivery
One of the breakthroughs of ACERT Technology is the concept of multiple injection fuel delivery. This process involves a high degree of precision as the combustion process grows in complexity and engine speeds and load demands change.
One key benefit of multiple injection technology is lower combustion chamber temperatures that in turn generate fewer emissions. In precisely shaping the combustion cycle, Caterpillar is also optimizing thorough combustion of the fuel, further reducing emissions output while giving customers more work for their fuel expense. |
|
ACERT Technology - Electronic Control
Caterpillar has been electronically controlling its engines since the middle 1980s. The culmination of this pioneering spirit is the ADEM A4 controller that precisely manages all engine systems. It is a 32-bit computer that uses sensors throughout the engine to regulate fuel delivery, valve timing and all other engine systems that require input to manage load and performance.
The ADEM A4 controller is the muscle behind engine responsiveness, self-diagnosis, fuel economy and emissions. Software offers flexibility in fuel mapping, allowing the engine to respond to specific application needs as well as weather and altitude conditions. |
|
ACERT Technology – Air Management
Engines need clean cool air in order to perform and as such air management is key to optimizing engine performance and controlling emissions. A new cross flow design in the cylinder head facilitates air movement, while tighter tolerances between the piston and cylinder liner reduces blow by gases.
The combination of the above three building blocks of ACERT Technology provide precise control of the combustion process. At this point in time, off-highway engines are NOT required to have an after treatment system. However, Caterpillar does have a Cat Diesel Oxidation Catalyst located between the engine and muffler for on-highway truck engines to meet current on-road engine emission regulations. |
|

|
|
Dual Horsepower
The Cat C18 diesel engine has dual horsepower capability, automatically increasing horsepower in higher roading gears for quicker acceleration on the haul road.
The low power setting is used 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 have complete control over injection timing, duration, rate and pressure under changing conditions over the entire engine operating range. The EUI controlled engine has improved fuel efficiency, more power, decreased smoke & emissions, faster hot & cold starts, better high altitude performance and less noise than mechanical injector engines. |
|
Electronic Control Module
The ECM utilizes advanced engine management software to monitor, control and protect the engine. ECM maintains an active electronic fault log that can speed troubleshooting. Engine speed governing requires no adjustment since it is fully electronic. In addition, ECM improves performance during cold starts, and compensating for high altitude operations and air filter plugging. Input from sensors allows the ECM to monitor and control injection, timing, injection pressure, engine cooling fan speed, ether starting aid, and hydraulic pumps to adjust to any operating condition. |
|
ADEM A4 Control Module
Controls engine rpm by adjusting the fuel duration, which results in quicker starts in hot and cold weather, better fuel economy, better operator response, and automatic compensation for altitude and filter plugging. Input from sensors allows the ADEM A4 controller to monitor and control injection, timing, injection pressure, engine cooling fan speed, ether starting aid and hydraulic pumps to adjust to any operating condition.
The ADEM A4 controller compensates for high altitude operations and air filter plugging. The A4 controller is air cooled, which reduces system complexity while maintaining performance. The previous module was fuel cooled. |
|
Greater Reliability
The EUI system has fewer moving parts than mechanical unit injection and requires few adjustments. The ADEM A4 controller communicates with the monitoring system (EMS) to warn the operator when problems arise, preventing major damage from occurring. |
|
Maintenance
EUI engines have virtually no mechanically controlled parts to wear or adjust. |
|
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. |
|
Ether Starting Aid
The ADEM A4 controller activates the continuous flow ether injection system during engine cranking to enhance cold weather starting. |
|
 | | Control Throttle Shifting (CTS)
Automatically synchronizes engine speed to transmission speed during shifting to reduce power train stress and increase component life. It also results in a smoother ride for the operator. |
|
Directional Shift Management
Reduces driveline torque and transmission clutch energy when directional shifts or shifts from neutral during high engine rpm are attempted. This helps prevent excessive transmission wear and increases drive train life. A pressure-sequencing valve assures that the speed clutches are engaged before the directional clutches, in order to absorb most of the torque load generated in direction changes. |
|
Low Battery Elevated Idle
The ADEM A4 controller automatically compensates for low alternator output at low idle by raising the rpm for brief intervals to keep the batteries fully charged. |
|
Altitude Compensation
The system de-rates fuel delivery as a function of barometric pressure as sensed by the system’s atmospheric pressure sensor. No manual adjustment is required. Auto deration prevents excessive combustion temperatures that could result in component damage. |
|
Diagnostic Capability
Cat® Electronic Technician (Cat ET) is used to display real-time pressures, temperatures, fuel settings and diagnostic messages as well as a historical information such as engine over-speeds, overheating, low oil pressure and air filter restriction events. |
|
Event Log
EMS has a large amount of memory to record problems detected by the control system. Included in the log is the hour (service meter unit) the event occurred, the number of occurrences for the event, an event identifier and problem code. The event log can be accessed using the Electronic Technician (Cat ET). |
|
Fuel Economy
Electronic controls optimize the timing setting for varying load conditions. The ADEM A4 controller matches timing to the load on the engine, engine rpm and temperature. |
|
Air Filter Restriction
ADEM A4 controller monitors air filter restriction and sends a warning message to the Electronic Monitoring System (EMS III) to alert the operator if the restriction exceeds the allowable limit. |
|
Scraper Electrical Harness
A ribbon wiring harness replaced the cable harness for improved wear and durability. Its greater flexibility oscillates better with machine movement, and polyurethane boots offer better protection against the elements. |
|
Automatic Belt Tensioning
Both the tractor and scraper engines have automatic belt tensioning rather than manual tensioning. The number of belts has been reduced to two on the tractor, and two on the scraper. Fan drive bearings on both the tractor and scraper engines with ACERT® technology eliminate servicing requirements. |
|
One-Piece Power Block
The jumpstart receptacle and disconnect switch are integrated into one-piece power block that provides better electrical integrity and serviceability. The disconnect switch with lockable cover locks out all power for servicing. |
|
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. |
|
Scraper Radiator
The scraper has a brazed aluminum core scraper radiator with composite tanks featuring 9 fins per inch. With the increased radiator fin spacing for both the tractor and the scraper, clogging in severe applications has been reduced. |
|
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. |
|
Power Train - Transmission
Electronic controls switch from converter drive to direct drive based on gear selection, maximizing efficiency and power application. Tractor and scraper engines are synchronized for smooth operation and longer service life. |
|
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. Gear selection choices are 1st, 2nd and Drive. |
|
Synchronized Scraper Transmission
The scraper transmission is electronically controlled by the tractor transmission, synchronizing the scraper transmission gear selection with that of the tractor transmission. The scraper transmission cannot be shifted manually. A neutral/run switch, located in the cab, allows the operator to disengage the scraper transmission. When the operator selects the “neutral” switch position, the scraper transmission is shifted into neutral. It remains in neutral until the operator selects the “run” switch position, upon which normal shifting of the scraper transmission will resume. |
|
Planetary Design
Provides larger contact area between gears than countershaft transmissions for greater load-carrying capacity. |
|
Transmission Hold
Allows the operator to maintain converter drive, or hold the current gear for enhanced control. The transmission hold switch is incorporated into the joystick controller and allows the operator to hold the machine in the current gear until the operation is completed (normally cut and/or fill). The neutral lock thumb control must be pressed to move the shifter from neutral. |
|
Programmable Top Gear Selection
Allows the operator to manually set the top gear (3rd - 8th) available to match conditions or to match the hauling speed of the fleet to specific job-site needs. To use the top gear button, with the engine running and the transmission shifter in “D”, the operator must hold the yellow button until the desired top gear appears on the gear display on the instrument panel. Releasing the yellow button sets the top gear. The top gear selected cannot exceed what is programmed into the TCC (Transmission/Chassis Control) controller. |
|
Retarder
The hydraulic retarder, optional on the 631G, should be used on downgrades to reduce wear on the service brakes and enhance machine control. The retarder acts as an internal brake on the driveline, minimizing the need to apply service brakes. The operator typically engages the retarder 3 to 4 seconds before the machine enters a downhill grade. |
|
Retarder Operation
The retarder is located on the torque converter output shaft between the transmission and the torque converter housing. As oil enters the retarder housing it flows into the vanes of the rotor. The rotor turns at engine speed, throwing oil against the stationary stator vanes on the retarder housing. As engine speed increases, the stator’s resistance to moving oil slows the rotation of the rotor thus slowing the machine. Optimal retarding action occurs when the engine is turning at rated rpm. |
|
Differential Control
Electronic differential lock helps prevent the drive wheels from spinning in poor underfoot conditions. The operator engages the differential lock with a foot control located in the cab. |
|
Neutral Coast Inhibitor
Prevents the transmission from shifting into neutral if the operator selects neutral while moving. The transmission control will select the proper gear for the given engine rpm and ground speed. |
|
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). |
|
Parking Brakes
The push-button operated parking brake features a spring-applied, air-released mechanism that operates the service brakes. |
|
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 delivers state-of-the-art ride, capacity, and material control while assuring the durability and reliability customers expect from Caterpillar. |
|
Cushion Hitch
The electronically actuated cushion hitch incorporates a parallelogram-type linkage for exceptional strength with nitrogen accumulators to deliver a smooth ride for enhanced operator comfort.
- cushion hitch lock down control for positive cutting edge down pressure when loading or spreading
- controlled oil flow dampens rebound oscillation
- leveling valve automatically centers piston in cylinder for all loads
- steel castings are used extensively to eliminate many welded joints and increase strength
- double-kingbolt design withstands high external forces and simplifies installation and removal
|
|
 | | Nitrogen Accumulators
Vertically mounted hydraulic cylinder transfers road shocks to nitrogen accumulators. Nitrogen accumulators absorb and dampen road shocks, thus reducing these loads from being transmitted to the operator. |
|
Lockout Switch
An operator-selectable lockout switch, located on the joystick, locks the cushion hitch for improved control of the cutting edge during loading and dumping. |
|
 | | Operator Station
Convenient control placement and a comfortable work environment are keys to high productivity. Features include electro-hydraulic controls, an available air seat suspension and advanced instrumentation. |
|
Multi-Adjustable Seat

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. |
|
Logical Control Placement
Placing only frequently used switches and indicator lights on the instrument panel, and less frequently used switches on the overhead console, improves efficiency and reduces reaching. |
|
Engine Speed Lock Controller
Allows the operator to maintain a given engine speed without using the throttle pedal. This reduces operator fatigue associated with holding the throttle pedal down for extended periods of time. An on/off toggle switch enables the Engine Speed Lock feature, and a lamp indicates the feature is active. The Engine Speed Lock feature is disabled by moving the rocker switch to the off position, or by applying either the service brakes or the retarder. |
|
 | | Simplified Transmission Control
Simplifies gear selection and provides operator-defined top gear control. Forward gear selection choices are 1, 2, and D (Drive). The transmission control lever was moved to accommodate the more frequently used single-lever implement control. Relocating the gear control to the rear position on the right hand side of the operator’s station increased legroom for the operator, resulting in a more spacious cab. |
|
Neutral Lock
The neutral lock thumb control must be pressed to move the shifter from neutral. To use the top gear button, with the engine running and the transmission shifter in “D”, the operator must hold the yellow button until the gear display on instrument panel indicates the desired top gear. When the desired top gear appears on the display, the operator releases the yellow button. This sets the top gear. The top gear selected by the operator cannot exceed what is programmed into the electronic transmission control unit. |
|
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
Traditionally wheel tractor scrapers have had three separate control levers for bowl, apron and ejector functions. The G-series has only one joystick controller to control all three of these functions. Simple and easy to operate, the joystick enhances the productivity of operators of all skill levels, regardless of application. Operators never need to remove their hand from the joystick while loading and unloading. It 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 (on front of joystick)
- Auger (on/off)
- Push-Pull (bail up/down)
* No rocker switch on standard open bowl. |
|

|
Easy Access Diagnostics
A variety of diagnostic codes are accessible through the EMS main display module, via the Electronic Technician (Cat ET). This offers a head start on problem solving, so with a radio call the service technician can know which tools, troubleshooting guides, and possibly even replacement parts to bring to the machine.
Real-time pressures, temperatures, fuel settings and historical information such as engine over-speeds, overheating, low oil pressure, and air filter restriction events can be accessed to help pinpoint the trouble spot. |
|
Greater Reliability
The EUI system has fewer moving parts than mechanical unit injection and requires few adjustments. The ADEM A4 controller communicates with the monitoring system (EMS) to warn the operator when problems arise, to help avoid major damage. |
|
Maintenance
EUI engines have virtually no mechanically controlled parts to wear or adjust. These have been replaced by electronic controls, reducing maintenance costs and increasing machine availability. |
|
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. |
|
Scraper Bowl
Caterpillar Scraper bowls are designed for excellent material flow and retention for fast cycle times and high productivity. |
|
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. For most efficient loading, use the thinnest edge that provides satisfactory wear life and impact resistance.
- Standard Cutting Edges - Center, End & Router Bits
- Serrated Cutting Edge - Center, Standard End Edges & Standard Router Bits
- ARM Cutting Edges - Center, End & Router Bits
- ARM Serrated Cutting Edge - Center, End, & Router Bits
|
|

For example, ARM scraper cutting edges and router bits will provide up to five times the wear life of conventional edges and router bits in high wear, low impact applications. Depending on applications, the serrated cutting edge may be more cost effective than the integrated tooth cutting edge. |
|
Level Cutting Edge
Used for finish work or for very high impact conditions where stinger breakage has been a problem: Standard Cutting Edges - Center, End & Router Bits |
|
Teeth and Adapters
Improve penetration into compacted material. The bolt-on adapters are available for all scrapers. |
|
Material Application
Well suited to handle a wide variety of material from clay to shot rock. |
|
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. |
|
Auger Arrangement
Provides self-loading capability with the same wide material appetite as an open bowl machine. |
|
 | | Versatility
The auger has a wide material appetite ranging from rock to free flowing material such as sand. |
|
Auger Mechanism

|
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
|
|
Slip Limiter Switch
Prevents rear wheel spin during loading. |
|
Hydraulic System
Single hydraulic system for entire machine with separate implement pumps/valves simplifies maintenance and improves reliability. |
|
Implement Valve Relocation
