The Cat C15 Electronically Controlled Unit Injection (EUI) diesel engine powers the tractor. With dual horsepower capability, it provides high power and torque rise for excellent lugging in tough loading conditions. The C15 is designed for long hours of continuous operation with high displacement and low RPM ratings.
The 627G is tandem powered by the Cat C9 scraper engine for peak performance and high productivity in self-loading applications. The C9 has a smaller physical envelope than the Cat 3306 it replaced, weighs less, and delivers more horsepower. In addition, all daily inspection points are located on the right hand side for easier maintenance.
Electronic engines deliver increased power when the auger is engaged or when the machine is in the roading gears, providing quicker acceleration on the haul road.
The C15 and the C9 electronic engines with ACERT technology meet US EPA Tier 3 and EU Stage III emission regulations. ACERT technology reduces emissions during the combustion process by using advanced technology in the air and fuel systems, in conjunction with integrated electronics. Caterpillar meets emission regulations at the combustion source rather than recycling exhaust gases.
Allows the operator to maintain a given engine speed without using the accelerator pedal. This eliminates operator fatigue associated with holding the pedal down for extended periods of time. An on/off rocker switch enables the Speed Lock feature, and a lamp indicates the feature is active. Moving the rocker switch to the off position, or activating the service brakes or the retarder, disables the feature.
The standard radiator for the tractor is the Next Generation Modular Radiator (NGMR) that features 9 fins per inch, whereas the previous model had a standard radiator of 33 fins per inch. The increased radiator fin spacing reduces clogging in severe applications.
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. Reverse gear operates in converter drive. All scraper gears operate in converter drive for increased torque capability during the cut and fill.
Redesigned axles on both the tractor and scraper accommodate wider brake shoes and brake drums, improving brake performance as much as 20 percent and reducing brake and drum wear as much as 75 percent.
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.
The electrical system has been redesigned to utilize three electronic control modules (ECM) on the tractor instead of four. The rear-powered scraper now has two ECMs rather than three.
Combined monitoring systems, easy access diagnostics and more durable components make routine maintenance and servicing simple and fast.
Electronic controls yield a fuel savings by optimizing the timing setting for varying conditions. The ECM matches timing to the load on the engine, engine speed and temperature.
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 has the capability to automatically issue alerts when the machine is being operated beyond owner defined time and location limits.
The ECM reads electronic sensors to determine the optimum fuel/air ratio, then precisely controls fuel during cranking, starting and acceleration to reduce smoke. The ECM system is faster and more efficient than mechanically controlling the governor rack position.
Increases legroom a full 3.5 inches (89 mm), and reduces knee contact points.
Gives the operator a comfortable workstation in any kind of weather. Relocated ventilation louvers improve airflow to the operator.
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.
Hood and front shroud width increased to accommodate the low emission engine, the air-to-air aftercooler (ATAAC), ether starting aid, and lights. Hood corners are sloped to maintain the same level of visibility as the E-Series.
Features a quad-gauge layout showing engine coolant temp, transmission/torque converter oil temp, fuel level, and system air pressure. The 627G tachometer can monitor either front or rear engine speeds. Once the 627G tractor engine has been started, the operator can start the rear engine from inside the cab. EMS III can display both front and rear engine information right in the cab.
Enhances operation during long haul cycles by allowing the operator to maintain a desired engine speed without maintaining pressure on the accelerator.
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.
Excellent productivity with a 10% increase in bowl capacity, improved draft arm protection, and better load retention. Low-profile design of the bowl offers less resistance to incoming materials, while cellular construction adds strength and dent resistance to bowl sides and floor.
Combines constant spreading control while minimizing carryback material. A spill guard on the ejector (standard on 627G) helps retain material and keep it from spilling over onto the rear of the scraper.
May be adjusted according to job conditions. For most efficient loading, use the thinnest edge that provides satisfactory wear life and impact resistance.
A wide variety of Ground Engaging Tool (GET) options, such as standard, serrated, and abrasion resistant material (ARM), are available to optimize scraper loading in various materials. Most are reversible to provide long life and reduced operating costs. Contact your Cat Dealer to learn more about the best tools for your applications.
Two engines ensure the power to handle steep grades, and makes possible all wheel drive to handle soft, slippery underfoot conditions.
Provides increased horsepower during the haul which results in faster cycle times.
Well suited to handle a wide variety of material from clay to shot rock.
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.
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.
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.
This system provides a more balanced, flexible fleet using fewer machines and less investment than comparable self-loading or push-loading systems.
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.
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.
Tractor engine automatically reverts to the higher setting when the auger motor is engaged.
Prevents rear wheel slip during loading.
Single hydraulic system for entire machine with separate implement pumps/valves simplifies maintenance and improves reliability.
Monitors machine status and provides real-time information to the operator including warnings of problems identified by the Electronic Control Modules.
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.
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.
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.
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.
The tractor has a standard two-piece door on the right side for better access to service points. The hood, hinged on the front and supported by spring struts, easily opens towards the front of the machine, for better access to the top of the engine.
Diagnostic codes are accessible through the EMS main display module, via the Cat ET. Relaying this information to the service technician can let him know which tools, troubleshooting guides, and possibly even replacement parts to bring to the machine.
You will find nearly all parts at our dealer parts counter. Cat dealers use a world-wide computer network to find in-stock parts to minimize machine down time. Save money with genuine Cat Reman parts. You receive the same warranty and reliability as new products at substantial cost savings.
