DURABILITY
Built Strong And Tough
•ACERT™ Technology maintains engine performance, efficiency and durability while reducing emissions
•Heavy duty components withstand all operating conditions
•Strong, solid structures built to last
EPA TIER III, EU STAGE III COMPLIANT C11 ENGINE. ACERT Technology combines proven systems with innovative new technologies to precisely deliver fuel to the combustion chamber. It maintains engine performance, efficiency and durability while dramatically
reducing emissions.
The Cat C11 with ACERT Technology is an 11.1 L displacement, 6-cylinder, electronically governed engine. Electronic fuel injection is provided through the well-proven Caterpillar mechanically actuated, electronically controlled unit injection (MEUI) system. A wastegate turbocharger, equipped with a titanium wheel for improved durability, combined with air-to-air aftercooling (ATAAC) provides consistent high horsepower with increased altitude capability.
Electronic Controller. The engine is governed by an electronic control module designated the A4:E4V2. The controller continually adjusts engine output based on load demand using a series of sensors located on the machine and engine.
Mechanically Actuated Electronic Unit Injectors (MEUI). The MEUI system has been at work in Cat engines across the product line with a proven track record of consistent, durable, reliable performance.
Engine Block and Pistons. The gray, cast iron engine block is made of the same material as the cylinder heads. Wall diameters are thicker than in previous designs while adjustments have been made to reduce sound levels and increase rigidity. One-piece all-steel pistons are housed within a wet, replaceable cast iron cylinder liner constructed of high-strength, heat-treated castings. Steel-forged connecting rods are larger in diameter and are connected to the crankshaft with two bolts.
Cylinder Head. The cylinder head is a one-piece design that incorporates cross-flow design to facilitate air movement. This allows the engine to
breathe cooler, cleaner air with less effort.
RADIATOR. Brazed aluminum construction provides a stronger joint for maximum durability and resistance to leaks. The 6-fins-per-inch, square-wave core design decreases the chance of blockage and plugging.
POWERSHIFT TRANSMISSION. The 966H continues to use heavy-duty powershift transmission technology proven on previous models and currently used up through the largest wheel loader built by Caterpillar, the 994F.
The planetary powershift transmission features heavy-duty components to handle the toughest applications. Built-in electronic controls enhance productivity and durability.
Control Throttle Shifting. Control Throttle Shifting regulates engine speed during high-energy directional changes for smoother shifting and longer component life.
Electronic Clutch Pressure Control.
Electronic Clutch Pressure Control (ECPC) system modulates clutches individually to improve shift quality, component life and operator comfort. Adjustment is simplified with all solenoid valves externally mounted on top of the transmission housing.
AXLES. The 966H axles are designed by Caterpillar for durability in all operating conditions. The front axle is rigidly mounted to the frame to support the weight of the wheel loader and withstand internal torque loads as well as external forces encountered throughout operation.
The rear axle is designed to allow ± 13° oscillation. All four wheels remain on the ground over uneven terrain providing excellent stability and traction.
Integrated Braking System. The Cat exclusive Integrated Braking System reduces axle oil temperatures and improves transmission neutralizer smoothness. IBS has a direct impact on durability of the axles and brakes especially in applications involving long distances and/or heavy braking.

STRUCTURES. The articulated frame design of the 966H features a durable box-section engine frame and rigid four-plate loader tower that is robotically welded. Robotic welding creates frame joints with deep plate penetration welds and excellent fusion for maximum strength and durability.
Engine End Frame (EEF). A full boxsection engine end frame with hitch plates at the front end provides a strong, rigid structure that resists twisting and impact loads. The result is an extremely solid mounting platform for the engine, transmission, axle, ROPS and other accessories.
Spread Hitch. The distance between the upper and lower hitch plates is an important contributor to machine performance and component life. The Caterpillar spread hitch design
provides excellent load distribution and bearing life. Both the upper and lower hitch pins pivot on double tapered roller bearings – improving durability by distributing both vertical and horizontal loads over a larger surface area.
The wide opening also provides excellent service access.
Non-Engine End Frame (NEEF).
The non-engine end frame provides a solid mounting base for the front axle, lift arms, lift cylinders and tilt cylinders. The fabricated, four-plate loader tower absorbs the forces associated with loading, twisting and penetration.
Counterweight. The one-piece counterweight is integrated into the 966H design and styling. This 2,517 lb (1142 kg) counterweight incorporates the rear lights into the top of the structure.
Linkage. The 966H linkage is a singletilt Z-bar design. Z-bar linkage generates excellent breakout force and good rack back angle for better bucket loading and load retention.
Lift arms are solid steel, providing superior strength with an excellent front end viewing area. The proven design offers excellent dump clearance and reach for exceptional matching to
both onand off-highway trucks.
Rotary sensors, for the tilt lever and lift circuit allow the operator to electronically set detent positions from the cab. A guard covers the sensor to protect it from damage.

PRODUCTIVITY
Work Smart And Move More
•Hydraulics are easy to control with low effort
•Maximum fuel efficiency and flexibility in idle speeds
•Consistent horsepower regardless of conditions
•Standard and optional features that maximize productivity
LOAD SENSING HYDRAULICS. The 966H features a load sensing hydraulic system that automatically adjusts to operating conditions to provide only the hydraulic flow required by the implement for improved fuel efficiency.
With the new M3PC Priority Proportional Pressure Compensation Valve, implement control is improved over the previous system – raise/lower and rack back/dump can be operated simultaneously and fine modulation is repeatable for improved productivity.
Operators will notice enhanced ease of operation, more rimpull into the pile and a 20% increase in lift force.
Electrohydraulic Implement Controls.
Electrohydraulic implement controls on the 966H provide the operator with incab programmable kickouts to prevent material spillage – improving productivity. The implement control console features an optional Forward/Neutral/Reverse switch allowing fast, easy directional changes to reduce cycle times.
CONSTANT NET HORSEPOWER.
On many competitive machines, gross horsepower is constant, meaning that net engine power available for actual work will vary based on demands made from parasitic sources, such as air conditioning or cooling fans.
The Cat C11 engine is electronically configured to provide constant net horsepower at full parasitic load enhancing productivity and improving fuel efficiency.
On-Demand Fan. With electronic control of the variable speed on-demand fan, temperature levels of the engine coolant, transmission oil, hydraulic oil and air inlet manifold are constantly monitored. This data is used to control and maintain fan speed at the level necessary to maintain normal system temperatures. Controlled fan speed improves fuel efficiency, lowers noise levels and reduces radiator plugging.
Separated Cooling System.
Many competitive loaders use cooling systems that pull air in from the sides, through the engine compartment and exhaust it out the rear of the machine. The 966H cooling system is isolated from the engine compartment by a nonmetallic shield. The hydraulically driven, variable speed fan draws in clean air from the rear of the machine and exhausts it out the sides and top of the hood. The end results are optimal cooling efficiency, increased fuel efficiency, less radiator plugging and reduced operator
sound levels.
PLANETARY POWERSHIFT TRANSMISSION. The electronic planetary powershift transmission with automatic shift capability is designed and built by Caterpillar. The very responsive, fullpower speed and directional changes provide excellent cycle times and productivity.
VARIABLE SHIFT CONTROL.
Match transmission shifting patterns to machine application requirements. Variable Shift Control (VSC) improves
shift quality and fuel efficiency in certain applications by allowing the transmission to upshift at lower engine RPMs.
RIDE CONTROL. The optional Ride Control System improves ride, performance and load retention when traveling over rough terrain. Operators gain confidence moving at higher speeds in load and carry operations decreasing cycle times and increasing productivity.
PAYLOAD CONTROL SYSTEM. Scales, designed specifically for Cat machines allow on-the-go weighing of material in the bucket. Operators load trucks more accurately and efficiently. Loading trucks right the first time equates to quicker cycles for the operator and more productivity for your operation.
Payload Control is offered as a factoryinstalled option. Driver tickets and a variety of reports can be printed with the addition of the optional printer.
