Intelligence
A new Traction Control System is now steering sensitive to differentiate between tire spin or high speed turns. spring applied secondary brakes) allowing it to engage sooner and at lower speeds. G Series TCS modulates power and braking instantaneously between the two wheel groups, allowing a more appropriate response to ground conditions, and returning the truck to solid footing much sooner.

Fuel Saving Strategies
Solutions that support your lowest cost per ton
Fuel Saving Strategies
· Standard Economy Mode G Series can adjust engine power based on your individual needs. With this feature, fuel savings are achieved by reducing power between 0. 15 to 15 percent. [. . . ] Extending brake life can also be achieved by choosing the optional Cat Engine Brake. This Caterpillar design works in conjunction with the automatic retarder control (ARC) to slow the machine.
Rear Wheel Steel Spindles
G Series wheel spindles are solid steel and interchangeable from one side to the other extending their useful service life.
Inverted Rear Cylinders
For G Series, Caterpillar has inverted the rear suspension cylinders to better protect the rods, keeping them cleaner for longer durations.
Structures
Updated castings, improved bolted joints and a larger rear axle have matched the chassis design with the higher power ratings and performance specifications of the truck.

Application specific designs for industry leading performance
G Series trucks retain the highly productive and reliable Cat C27 ACERT diesel engine. · With a 5% boost in power, the C27 is delivering higher torque for work. · With the precision and responsiveness of Cat MEUITM fuel injectors and electronic controls, the C27 accurately controls fuel, emissions and performance. · The C27 is carefully balanced with vibration controls that reduce noise and protect against unnecessary wear. · The C27 is cooled by either a demand fan (standard on Tier 4 Final) or conventional cooling fan.
Planetary Powershift Transmission
With new control strategies, this proven transmission is better than ever. Its new features include gear changes as smooth as an automobile and more torque through the shifts getting the truck up to speed faster and negotiating grades quicker.

Emission Controls
Tier 4 Final Emission Controls
Major improvements for air quality using simple to use, reliable solutions
Caterpillar offers a simple and robust U. S. Other than normal maintenance, this system requires no additional input or intervention by the operator.
NOx Reduction
Supported by cleaner burning, ultra-low sulfur diesel fuel and low ash oils, Caterpillar uses its engine-mounted NOx Reduction System (NRS) Technology to cool combustion chamber temperatures to control NOx production.
PM Reduction
Located on top of the engine are two diesel oxidation catalysts (DOC), one for each exhaust outlet. These injectors offer exceptional fuel atomization for engines running at slower speeds. MEUI-C injectors have an improved fuel shut off response time, saving fuel and reducing emissions. For customers purchasing trucks outside of North America, Caterpillar offers emission controls similar to those used for Tier 2/Stage II regulations.

G Series Body Strategy
Caterpillar has made it easier to get the right body for your materials and job site needs. Cat trucks have historically offered industry leading availability, life cycles and parts commonality. Today we offer even more ways to reduce our impact on the environment. With G Series, Caterpillar is pleased to be releasing its first North American Tier 4 Final product two years prior to the implementation of the regulation. In addition to contributing to better air quality, G Series offers lower operator sound levels and new ways to conserve fuel. · Fuel conservation features: two fuel economy modes, speed limiting, Auto Neutral Idle, Engine Idle Shutdown, new Traction Control System · Keeping the site clean with grouped service locations, ecology drains and convenient, optional fluid fill and electrical service centers · Reducing operator cab noise levels by 50% from previous trucks · Longer component life for tires using TCS and TKPH/TMPH · Longer life steel spindles, new brake designs, stronger frame · Cat Reman parts offer recycling and reuse opportunities with no risk · Longer service life for hydraulic oil filters (1, 000 hrs), and air filters with precleaner installed · Improved air quality with Tier 4 Final emission controls (for North America) reducing Nox and Particulate Matter by 90% over Tier 3 as well as reduced emissions from fuel conservation · Parts commonality with other Cat equipment

Retarding Performance (Tier 2 Equivalent)
To determine retarding performance: Add lengths of all downhill segments and, using this total, refer to proper retarding chart. Effective grade equals actual % grade minus 1% for each 10 kg/t (20 lb/ton) of rolling resistance. From this weight-effective grade point, read horizontally to the curve with the highest obtainable gear, then down to maximum descent speed brakes can properly handle without exceeding cooling capacity. The following charts are based on these conditions: 32° C (90° F) ambient temperature, at sea level, with 24. 00R35 (E4) tires. [. . . ]
