Engine



Provides power, reliability and acts as a working counterweight in the rear of the machine, for optimum machine balance.

Cat C6.6 ACERT



The Cat C6.6 is a 6.6 liter 403 in3 displacement, sixcylinder, inline configured engine that utilizes the Caterpillar Common Rail fuel system for fuel delivery. It uses ACERT Technology, a series of Caterpillar engineered innovations that provide advanced electronic control, precision fuel delivery and refined air management, resulting in outstanding performance and lower emissions. The C6.6 with ACERT Technology offers a compact design with big, heavyduty engine features for outstanding durability, reliability and performance. The C6.6 incorporates a new cross flow cylinder head design, 4 valve head and an ADEM A4 electronic controller. The C6.6 also features proven cylinder block, pistons and crankshaft and incorporates the common rail fuel system. ACERT technology enables the C6.6 engine to meet the U.S. EPA Tier 3, European Union Stage IIIA and Japan Ministry of Land, Infrastructure Transport Step 3 emissions standards, which dramatically reduce nitrogen oxide NOx and other emissions. ACERT technology used on the C6.6 consists of three basic building block systems electronic control, fuel delivery, and air management. These have been refined to control the combustion process to a higher degree than ever before possible.

Electronic control. ADEM A4



The Advanced Diesel Engine Management Electronic Control Module continuously monitors important engine conditions and functions. It uses sensors throughout the engine to regulate fuel delivery and all other engine systems that require input to manage load and performance. ADEM A4 is the brain behind engine responsiveness, selfdiagnosis, controlling emissions, and fuel economy.

Fuel System



Through multiple injection fuel delivery, fuel is introduced in the combustion chamber in a number of precisely controlled microburst. Injecting fuel in this way allows for precise shaping of the combustion cycle. The ADEM A4 module directs the injectors to deliver precise quantities of fuel at exactly the right times during combustion cycle. This process provides precise control over a range of combustion variables, which can be regulated to produce higher performance with fewer emissions. Fuel is delivered at high pressure to each combustion chamber through a Caterpillar designed injector linked to a high pressure Common Rail.

Air Management



Air management is a key concept in optimizing engine performance and controlling emissions. Engines must breathe clean cool air in order to perform. To aid this, the C6.6 uses a turbocharger fitted with a smart waste gate to give precise and reliable control of the boost pressure. A new crossflow design in the cylinder head facilitates air movement, while tighter tolerances between the piston and cylinder liner are reducing blow by gases.

Fuel pump



The C6.6 uses an oillubricated highpressure fuel pump to feed the common rail. By using an oillubricated fuel pump, the C6.6 has been designed to be more tolerant of alternative fuels.

Fuel Priming Pump



An electrical fuelpriming pump, standard, is located between the fuel tank and the combined water separatorprimary fuel filter.

Starting System



The Electronic Speed Selector Switch A, a rocker switch located on the right console, sets the engine rpm. The ADEM A4 engine controller will always start the engine in low idle. The engine rpm can be seen on the digital display of the instrument cluster in the gage cluster or in the performance menu in Messenger.

AirtoAir After cooler ATAAC



The airtoair after cooler is a single pass, aluminum, heat exchanger or cooling system for the pressurized air coming from the turbocharger, before it enters the engine intake manifold. Cooling the pressurized air from the turbocharger makes the engine intake air even denser. The increased air volume in the cylinders results in more power, improved combustion, and reduced exhaust emissions.

Servicability



Unit injectors and high pressure fuel lines can be serviced individually, without the need to service the whole fuel system.

Engine Installation



The engine is installed using rubber mounts to reduce the transfer of engine vibration to the frame and cab, lowering operator vibration, sound levels, and fatigue.

Rear Engine Location



Rear engine location allows excellent forward visibility, while serving as a working counterweight. It also helps reduce radiator plugging while providing easy service access to the engine and other major components.

Cooling module architecture



The cooling system is a single cooling unit, which includes Radiator, ATAAC, Oil cooler and Fan installation. The cooling module is located at the rear of the loader, away from dust and debris stirred up by the bucket while the machine is working.

Hydraulic ondemand fan



The fan is a hydraulic demand type one with optional reversible function, operating in sucker mode. It gives the best efficiency and avoids also sucking the dust and debris coming from the outside into the cooling package. The complete cooling package has been designed for a very easy maintenance with a complete accessibility to the cores for cleaning fan door swing out opening, latches, and a very high safety level.

Operator Station

Gage clusterself test.



The gauge cluster selftest verifies that the main display module is operating properly every time the key start switch is turned from the off to the on position. NOTE If the machine is not equipped with Messenger, the numeric display will show fault codes.

Hydrostatic Drive



The electronically controlled hydrostatic drive helps provide quick response for shorter cycle times and increased productivity.



The electronically controlled hydrostatic drive system automatically matches machine travel speed to the combined travel and implement loads on the machine, enabling maximum travel speed, up to the speed selected by the operator.

Electronic Hydrostatic Control EHC



Hydrostatic system has integrated electrohydraulic controls, sized for optimum performance and efficiency. Position in the machine provides ease of access for serviceability.

Variable Displacement Pumps and Drive Motors



Variable displacement pumps and drive motors are electronically controlled by the EHC, offering high efficiency and precise travel. Each track is independently driven by a separate hydraulic circuit consisting of one pump, connected by Cat XT6 hydraulic hose and couplings to a piston motor.

Travel Speeds



Travel speeds are infinitely variable between zero and top speed. Two speed modes work and travel, provide two different speed ranges to best match machine speed and torque to the job conditions for maximum productivity. Maximum travel speed is 10 kph 6.2 mph when the switch is set in the travel position.

SpeedDirection Control Lever SDL



The operator controls the speed of the machine and the direction of travel with a single SpeedDirection control Lever SDL located on the left console. The reverse V pattern of the SDL is designed to prevent an accidental fullspeedforward command when the loader encounters sudden resistance while traveling forward.

Braking



Braking is accomplished by moving the SpeedDirection control lever on the left console to a slower position closer to the top of the Reverse V, or all the way to the Brakeson position at the point of the Reverse V, The center foot pedal can also be used for emergency braking.

Steering



Steering is accomplished by changing relative pump flows andor motor displacements, which causes one track to rotate slower than the other track. A more aggressive steering command pushing one foot pedal down farther will cause one track to stopreverse while the other track continues to rotate.

Maneuverability



The hydrostatic drive train also offers independent power and control of each track, with fast acceleration, infinitely variable speeds, and automatic, onthego, direction changes for each track. The operator can command smooth power turns or even counterrotation of the tracks by simply pushing one of the steering pedals. The Caterpillar hydrostatic drive system manages itself, freeing the operator to concentrate on using the Cat track loaders superb agility, speed, and maneuverability to do more productive work.

SystemOne Undercarriage



The SystemOne undercarriage was designed exclusively for Caterpillar machines to reduce customers operating costs, downtime and maintenance intervals.

Revolutionary Undercarriage



SystemOne is the latest innovation in a century of undercarriage leadership. Nearly every major undercarriage improvement over the last 100 years has come from Caterpillar. It was designed to reduce customers operating costs and maintenance intervals. The revolutionary Cat SystemOneTM Undercarriage provides maximum undercarriage life and reliability no matter the application, environment or underfoot conditions. Built to last longer and require less maintenance it ensures a dramatic drop in operating costs.

Track Roller Frames



The track roller frames are a welded, box section design, which provides strength and resistance to bending without adding extra weight. The track roller frames are pinned at the rear to the loader main frame with pivot shafts, which allow the front of the track roller frames to swing or oscillate about the pivot shafts at the rear.

Guiding System



Better, more rigid guiding. The guiding system contacts link rails instead of pin ends and helps keep the track within the roller system.

Rollers



The 953D has six track rollers, which spread machine weight over a large area and a single upper carrier roller on each side mounts to the machine mainframe. The rollers and carrier rollers have been redesigned to run with the system. This will lead directly to better guiding. All rollers in this new system are all single flange rollers with increased flange diameter. This will also increase your guiding capability.

Cartridge Joints



Factorysealed cartridge joints are welded to control end play. They offer improved seal integrity through an innovative new sealing system and do not depend on the link interface to remain sealed. As with all new Cat undercarriage products, they are filled with special oils.

Track Shoes



The shoes for SystemOne are unique to this system. Several track shoe types tailor your machine for work in all underfoot conditions. The SystemOne links have a straight rather than offset bolt hole pattern. Double grouser standard or narrow track shoes are available. The standard shoe can be fitted with center hole to reduce material packing.

Longlife Sprockets



The sprockets, thanks to the rotating bushing design track, will be able to be reused over the life of a couple of undercarriages. This helps to cut down on replacement cost.

Oscillating Undercarriage



The undercarriage on the 953D features an oscillating track roller frame design which decreases ground shock to the machine, increases machine stability, and provides a smoother, more comfortable ride for the operator. Oscillating track roller frames keep more of the track on the ground when operating on uneven terrain, which increases machine stability, felt by the operator, allowing faster machine operation, increased machine productivity and reduced operator fatigue.

Track Adjuster



The track adjuster and mechanical recoil system uses a large recoil spring and grease filled adjustment cylinder, which allows the idler to move forward and back to maintain proper track tension as it absorbs undercarriage shock loads.

Equalizer Bar



The equalizer bar is pinned in its center to the machine mainframe and at the ends to each track roller frame. This allows the forward ends of the track roller frames to oscillate, or move vertically, to keep more track on the ground in uneven underfoot conditions. The equalizer bar also provides a more stable work platform for the operator, who will be comfortable working at faster speeds for increased productivity.

Structure



Durable Slab section Frame and Loader Tower with increased space for larger components.

Mainframe and Loader Tower



The 953D Main Frame and Loader Tower is a single, slab rails with reinforced crossings, with castings and forgings incorporated at points of high stress, to distribute those stresses over wider areas for long structural life.

Design



The part of the frame below the engine and operators station consists of two slabsection sideframe rails, which are joined at the rear by a boxsection cross member. The Slabsection 953D frame resists twisting and impact forces to provide a solid foundation for all the components it supports. Mounting points for the final drives, pivot shafts, and platform are built into each mainframe side rail.

Frame side plates



The frame side plates are made of mild steel, which provides strength and resists shock and bending stresses. Deep penetrating, Backed up welds are used for maximum strength.

Loader tower



The loader tower is integral with the basic main frame. The one slab plate continues forward to become one side of the loader tower in order to provide smooth transition to loads from linkages to the mainframe rails. The loader tower provides a solid mount for lift arms, lift cylinders, and Zbar tilt cylinder. A boxsection cross member is welded below the two inboard loader tower plates to add strength. The equalizer bar, which connects the track roller frames to the main frame, is mounted below the loader tower. The result is an integrated main frame and loader tower assembly which will accommodate maximum loads capability. The engine is at the rear, where its weight serves as a working counterweight to balance the machine for full bucket loads without adding inefficient dead weight.

ZBar linkage



Breakout force is exceptionally high due to mechanical advantage of Zbar linkage design, and hydraulic pressure applied to the head end of the tilt cylinder. Using a single tilt cylinder and linkage provides the operator a better view of the work area, bucket, and cutting edge.

Sealed Loader Linkage



The 953D linkage has fewer grease points compared to other linkage designs because every pin joint is sealed to keep grease in and dirt out. Fewer grease points and sealed pins means less downtime for maintenance allowing more working hours between servicing.

Lift Arms



The two arms are welded into a single unit, using a weldfabricated crosstube. The tilt link Dog Bone is a single forging. The 953D linkage design combines the advantages of strength and durability with minimum structural weight, so that productivity is not penalized by excess weight in the linkage.

Special Application Arrangements



Special arrangements improve the 953Ds performance in special applications.



With the addition of certain special modifications, the capabilities of the 953D can be further expanded to handle some very harsh working conditions.

Waste Handling Arrangements



Waste Handling arrangements provide added protection and are designed to make the 953D perform well in landfills, or any waste handling applications where the machine spreads, compacts, sorts, shreds and crushes materials.

Shiphold Arrangement



The 953D with its low ground pressure and excellent stability works well on top of loose materials, cleaning the cargo from the sides of the holds and moving it into position for the unloading system. Lifting eyes are included so that the 953D can be lifted from the dock to the hold.

Wide Gauge



For underfoot conditions that require even lower ground pressure than the standard 953D undercarriage the gauge of the machine can be widened by 300 mm 11.8 inches and the track shoe width increased to 800mm 31.5inches. The ground pressure is decreased to 43.3 kPa 6.3 psi.

Custom Products Arrangements



Other arrangements beyond those shown here are available. For other customdesigned arrangements for specific applications, contact your Caterpillar Dealer.

Versatility

Constructed with a trashrack for increased capacity, extra strength and better load retention. Ideal for applications in the harsh refuse market, whether digging or spreading material at the landfill or grasping and loading refuse at a transfer station.

Bucket Protection Options



Caterpillar offers several types of adapters, tips, and cutting edges, which increase bucket life and maximize performance.

K Series Tooth System



The KSeries tooth system provides longer tip and adapter life, faster cycle time with greater bucket fills and reduced machine strain. Therefore, it contributes to the reduction of operating costs. Easy and convenient during the installation, this new system provides a very good response to the need of reliability and durability of such components.

Longer Tooth Life



Tips are installed with a slight twist and secured with a onepiece retainer, providing less tip movement and nose wear.

Stable System Geometry



Opposing, sloped rails on the adapter provide full length stabilization with minimal movement. The tip bears directly on the end of the adapter nose to absorb thrust loads, leading to better tip retention and a longer adapter life.

Easy Installation and Removal



Opposing sloped side rails and flanks keep the tip on the nose as the retainer is being installed and removed. The onepiece vertical retainer requires low force and no special tools, allowing faster and easier removal and installation, amounting to less machine down time for tip changes.

Sharper Digging Profile



Lower height at the front and the back of the nose provides a sharper profile. This provides more production, less machine strain and lower cost of machine operation.

Reversible Tips



Each tip ear has a retainer groove with a locking recess. Tips can be run in one direction, then flipped, or reversed, to get the maximum use of wear material from the tip.
