950G SERIES II

Performance and comfort you can feel, delivering strong breakout force, fast cycle times, and smooth shifts for optimal productivity.




BENEFITS & FEATURES
Engine
The 950G II provides more power, excellent fuel economy, and reduced maintenance.


Engine

Powerful Performance
The 3126B ATAAC diesel engine delivers net power of 136 kW (183 hp), and meets EPA Tier 2 emissions standards. Its advanced fuel system keeps fuel at low pressure in the lines until it is injected into the cylinder. Fuel pressure is created hydraulically in response to a signal from the ADEM™ III Electronic Control Module.

Electronic Control Module
The Advanced Diesel Engine Module (ADEM III) fuel system is a proprietary electronic control module, which provides improved engine response and fuel efficiency, plus advanced diagnostics and reduced emissions. Altitude capability is increased to 3050 meters (10,000 feet) without derating. ADEM III allows full electronic integration of the engine and transmission for maximum power train efficiency.

Turbocharged, ATAAC
Turbocharging packs dense air into the cylinders for more complete combustion and lower emissions. Air-to-air aftercooling provides a separate cooling system for intake manifold air. The ATAAC system reduces smoke and emissions by providing cooler inlet air for more efficient combustion.

Constant Net Horsepower
The 950GII’s electronic engine is integrated with an on-demand cooling fan. The engine compensates for varying fan loads and provides constant net horsepower, regardless of operating conditions. A consistent level of "working" horsepower is provided and fuel consumption is reduced.

Oil Change Intervals
The engine oil change interval is increased to 500 hours (with CH-4 oil), reducing costs and downtime.

Electronic Transmission
Advanced Caterpillar power train is reliable and fuel efficient.


Electronic Transmission

Electronic Power Shift Transmission
The electronic power shift transmission with automatic shift capability is a durable planetary design built by Caterpillar. It is electronically controlled and allows full power shifts and directional changes. Fully modulated gear shifts contribute to operator comfort and increase component life.

Electronic Clutch Pressure Control (ECPC)
Senses input from both the transmission and the operator controls in the cab to modulate each individual clutch through a proportional electro-hydraulic valve. This results in smoother shifts (speed and directional). Energy is modulated into the clutches, resulting in longer clutch life.

Integrated Braking System
Integrates a downshifting and neutralizer logic into the left-hand brake pedal. IBS increases performance and productivity with an optimized transmission neutralizer and automatic downshifting. The Integrated Braking System also lowers owning and operating costs by reducing axle oil temperatures, which can extend service brake life.

Free Wheel Stator Torque Converter
The Free Wheel Stator torque converter (FWSTC) improves machine power train efficiency and contributes to improved fuel economy in certain applications. It reduces drag in the torque converter at high turbine speed/impeller speed ratios.

Electro-Hydraulic Valves
The six proportional electro-hydraulic valves pressurizing the clutches are identical and bolted on top of the transmission.

Easy Service
Daily level check is done from the ground through a well-protected sight gauge. An oil sampling valve allows quick, clean access to the transmission for S•O•SSM oil analysis.

Variable Shift Control
Transmission software which allows the operator to select three different shift patterns based on the application and operating preferences. This feature reduces fuel consumption, depending on the application. In all modes, full machine power remains available for loading.

Cooling System
New G Series II cooling package reduces radiator plugging and improves fuel efficiency.


Cooling System

Reverse Flow
Air enters through the rear grill and exits out the top opening and side hood doors. Rear air flow picks up less debris from the ground, reducing plugging.

Improved System Access
The 950G II adds a swing-out grill, hydraulic oil cooler and air conditioner condenser for easier cleaning. Side panels open to allow access to both sides of the radiator cores for cleaning. A heavy duty Airborne Debris Grill, with 4 mm perforations is available as an attachment.

On-Demand Fan
Electronically controlled, variable speed on-demand fan adjusts to meet the varying cooling requirements of the machine. Fan speed is determined by oil, coolant and inlet manifold temperatures. In cooler operating conditions, average fan speed is reduced, resulting in less fuel consumption, lower noise levels and less radiator plugging.

Unit Core Radiator
New unit core radiator with square wave shaped fins. Lower fin density (6 fins per inch) allows debris to pass through more easily.

Enviromental Machine
Caterpillar cares about the environment and continues to develop innovative solutions.


Low Exhaust Emissions
The Cat 3126B ATAAC engine used in the 950G Series II is a low emission engine designed to meet EPA Tier 2 emissions regulations. It is electronically controlled, with air-to-air aftercooling for more efficient combustion and cleaner emissions.

Reduced Sound
The electronic on-demand fan automatically regulates fan speed depending on cooling requirements. The fan draws less horsepower in cooler ambient temperatures, which reduces fuel consumption. Sound levels are also reduced when the fan slows down. There is additional insulation around the engine to reduce sound levels.

Environmental Fluids
Extended Life Coolant/Antifreeze with anti-foaming and anti-corrosion properties provide extended service intervals (up to 6000 hours) and requires less frequent fluid changes and disposals. Air conditioning refrigerant is CFC-free.

Fewer Leaks And Spills
Oil sampling valves and pressure test ports are included for easy service diagnostics, with less chance of spills. Filters are positioned vertically and located for easy access, allowing for removal without fluid spillage. Lubricant filters and drains are designed to avoid spills.

Ecology Drains
Standard for the engine, transmission, hydraulics, radiator and fuel. Activating the valve allows fluid to be drained into a container without spillage. Axle oil ecology drains are an attachment and allow quicker oil changes with reduced spillage.

Rebuildable Components
Many major components are designed to be rebuilt. Worn components can be remanufactured instead of thrown out.

Operator Station
The ultimate in wheel loader operator comfort and efficiency.
