ACERT Technology works at the point of combustion to optimize engine performance and provide low exhaust emissions. The C9 engine, matched with the torque divider and power shift transmission, provides years of dependable and effi cient service.

C9 with ACERT Technology. With a displacement of 8.8 L (537 in3), the Cat C9 engine retains the reliability, durability, and performance of its predecessor, while adding the benefi ts of Cat ACERT Technology. The engine is certifi ed to China Stage II (GB 20891-2007) emission regulations. Emissions are within equivalent EPA Tier 2/EU Stage II regulation limits.

ACERT Technology has the fl exibility to allow the D7R to meet equivalent EPA Tier 3/EU Stage IIIA emission levels when emerging market regulations dictate.

ACERT Technology provides longer service life over other emission reduction technology. ACERT engines are based on proven engine designs and are one of the most thoroughly tested Cat products ever introduced.

ACERT engines will provide the most durable emission solutions. Other competitive emission technologies can experience increased heat rejection, more soot loading, and fuel sulfur sensitivity that can translate to increased engine wear and shorter serviceable life. ACERT Technology boosts operating effi ciency and reduces fuel consumption. Due to the advanced combustion chamber design and the electronic control module that optimizes the air and fuel mixture, Cat engines with ACERT Technology performs an effi cient burn, which means better performance.

Cat engines with ACERT Technology are lessexpensive to operate when compared to other equivalent emission solutions. Fueland maintenance account for a large portionof equipment operating costs. Cat ACERTengines burn less fuel, which brings more moneyto the bottom line. ACERT Technology can provide the ability to extend oil change intervals to 500 hours when recommended fl uid and maintenance practices are adhered to, which equates to buying oil and fi lters less often than the competition. This extended service life means that the engine will not need an overhaul as soon, resulting in less overall operating expense.


Engine

The advantage of the ACERT Technology is to allow the engine to work to a mapped performance. The D7R engine offers a constant net horsepower band to maintain the highest performance when operating at various engine speeds. The D7R features 192kW (257 fwhp) constant net engine power between 1,500 and 2,000 rpm with a maximum net engine power of 194 kW (260 fwhp) at 1,900 rpm. At rated engine speed, the D7R is 179 kW (240 fwhp) at2,100 rpm.

Block. The one-piece, grey iron block features generous ribbing for stiffness and heavy bearing bulkheads for rigidity and strength. Straight O-ring connection points reduce the loss of engine oil and liquids.

Water Separator andFilter. The D7R features a 10 micron primary fi lter and water separator to remove contaminants before moving to the secondary fuel fi lters. The water separator features a large bowl to trap water in fuel. The system includes an electric fuel priming pump.

High Effi ciency Oil Filter. The oil fi lter has been refi ned to capture even smaller particles, improving engine life.

Cylinder Head. A four-valve cross-fl ow designprovides improved combustion through enhanced air fl ow from smooth intake and exhaust ports. An isolated valve cover makes the engine quieter. Six bolts per cylinder ensure maximum seal at the block joint with minimum distortion. The cylinder head also features lighter, yet stronger, rocker arms and valve bridges, allowing more dynamic camshaft design. This improves combustion, resulting in better response, lower emissions, and reduced fuel costs.


Fractured Split Connecting Rods. Fractured-split connecting rods are designed to create near-perfect joint alignment, maximizing rod bearing life. This, in combination with a high effi ciency oil fi lter, ensures long engine life.

A4 Engine ECM

Engine Controller. The air-cooled electronic control module manages fuel delivery to get the best performance per liter (gallon) of fuel used. Flexible fuel mapping allows the engine to respond quickly to varying application needs. It tracks engine and machine conditions while keeping the engine operating at peak effi ciency.

Fuel Delivery. Multiple injection fuel deliveryinvolves a high degree of precision. Precisely controlling the combustion cycle lowers combustion chamber temperatures, generating lower emissions and optimizing fuel economy. This translates into more work output per unit of fuel.

HEUI Fuel System. The Hydraulic Electronic Unit Injector (HEUI) fuel system is highly evolved, with a proven record of reliability. HEUI uses the technical advancement of an electronic control system with the fl exibility of hydraulically controlled unit fuel injection. Thesystem excels in its ability to control injection pressure over the entire engine operating speed range. These features allow the C9 engine to have complete control over injection timing, duration, and pressure.

ATAAC. The Air-to-Air After cooler (ATAAC) is a single pass, aluminum, heat exchangeror 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, forcing more oxygen into the cylinders during the intake stroke. Theextra oxygen packed into the cylinders isavailable for combustion during the power stroke when the fuel is burned. Thebenefi ts are:

More power

Improved fuel combustion

Reduced exhaust emissions

Full engine power to higher altitude

Service. The C9 engine offers easier maintenance and repair through monitoring key functions and logging critical indicators. Electronic diagnostic access to the power train is possible with a single tool, the Cat Electronic Technician.

Drive Train

Drive Train. The mechanically controlled power shift transmission and differential steering work in combination with the C9 engine to deliver the outstanding power and reliability the customers expect from Cat equipment.


Drive Train

Differential Steering System. A planetary differential turns the machine by speeding upone track and slowing the other, while maintaining full power to both. The differential steering control will be mechanically controlled. This allows the tractor to be more powerful while turning and spreading loads on job sites.

Differential steering provides power to both track sides and a constant center line speed during a turn. A conventional clutch/brake machine interrupts power to the machine during a turn and slows overall center line speed.

The system consists of three planetary gear sets.

Two planetary gear sets (steering and drive) make up the dual differential, which performs the traditional drive function (forward or reverse). Unlike competitive machines, the differential also performs a steering function with input from the bi-directional, fi xed displacement steeringmotor.

A third planetary gear set, the equalizing planetary, resides inside the transmission case. It is connected to the dual differential, providing a maximum speed difference between the right and left fi nal drives during a turn.

Thick, Large Diameter Plates and Clutch Disks. Thick, large diameter plates and disks provide higher torque capacity and increased service life.

Brake Housing. Brake housing features cast rib design for more durability.

Cooling Oil Valve. Cooling oil valves control oil fl ow to improve brake heat dissipation, extending brake life.

Tapered Roller Bearings. Tapered roller bearing design provides increased service life.

Double Reduction Planetary Final Drive. Caterpillar uses double reduction planetary fi nal drives in the D7R. The fi nal drives are designed with 3 planetary gears to spread high torque loads out evenly for long fi nal drive life.

Seals. Splash lubrication and Duo-Cone seals extend service life.


Elevated Final Drive. Since its ground-breaking introduction in 1978 this work proven design offers a variety of benefi ts such as higher production, excellent ride and balance, and longer component life. Ground and implement shock loads are transferred to the mainframe to protect fi nal drives, axles and steering components from harsh impacts and provide smoother ride.

The elevated sprocket design gives the operator excellent sight lines to the blade, sides and back of the machine. However, machine center of gravity remains low, offering excellent stability, balance and traction.

Modular undercarriage components simplify service, and modular power train components make it quick to remove and repair the transmission, fi nal drives, differential orbrakesfor reduced downtime.

Heavy Duty Undercarriage. The non-suspended heavy duty undercarriage is well suited to aggressive applications like forestry, side-slopes, or working in rocky or uneven terrain. Components are designed for extended wear life in abrasive conditions and high impact applications. Specifi cally engineered to match the requirements of medium size machines with an elevated sprocket operating in demanding work environments, heavy duty track features stronger links, pins and bushings that signifi cantly offset the effects of high-impact loads and stresses to extend system wear life. This is offered as the standard track link offering onthe D7R Track-Type Tractor.

Undercarriage


Undercarriage

Sealed and Lubricated Track. The heavy-duty, sealed and lubricated track is designed for superior track life. A wide bushing strap aids retention and provides resistance to bore stretching and cracking. The design offers excellent seal-ability and link rail wear life. Robust rail material promotes link and roller system wear life.

Since introducing Sealed and Lubricated (S&L) track in 1974, Caterpillar has consistently enhanced its design to meet the specifi c needs of your applications. Each track component has undergone and continues to undergo stringent improvement process and as a result, S&L track offers major advantages, all of which add up to longer wear life and reduced Owning & Operating Costs:

Sophisticated heat-treat processes ensure track links have high core hardness, helping to hold the track section together and preventing leaks caused by links walking off the pin.

Cross-drilled pins provide an oil passage between the pin and the bushing. Carefully machined oil reservoirs ensure proper oil distribution.

Polished bushing ends prevent accelerated seal lip wear. Stepped bushings, which are thicker in the middle, provide more external wear material.

Rigid seal, which consists of a fl exible load ring, rigid seal ring and thrust ring, provides better sealability in all underfoot conditions, reducing the effects of impact on track joints that can cause premature seal failure.

Standard Arrangement

XR Arrangement

LGP Arrangement

Standard arrangement (40-Section Track)

Performs well in many applications with fi rm to soft underfoot conditions.

XR arrangement (41-Section Track)

More track to the rear positions the tractors weight forward, which increases traction and stability for drawbar, skidding, and ripping applications.

Longer roller frame also improves fl otation in softer underfoot conditions.

LGP arrangement (43-Section Track)

Specially designed to work in soft and swampy conditions.

Wider gauge, wide track shoes and long track frames, increase track contact area and reduce ground pressure for improved stability and excellent fl otation in soft underfoot conditions.

Structure

Frame and Castings. The D7R frame is built to absorb high impact shock loads and twisting forces. The frame has a reinforced saddle and a welded front cross-member. Both add strength to the frame to better handle lateral and twisting forces. Steel castings augment thestrength of the main case.

The D7R frame is designed for multiple lives by rebuilding many of the components. Thisstrong sustainability element reduces waste and the use of natural resources. It also drives lifetime costs down and extends the profi tability cycle of the machine over the whole life ownership.

Tag Link Mounting Blade to Mainframe

Tag-Link. The tag-link blade mounting brings the blade closer to the machine for excellent maneuverability, machine balance and blade penetration. The tag-link design provides solid lateral stability and better cylinder positions for constant pryout independent of blade height. The tag-link also eliminates the need for diagonal bracing because it transfers side loads to the mainframe instead of the dozer push-arms.

Structure. Cat Track-Type Tractors set the industry standard for durability. The D7R is built and engineered to provide the solid support needed for maximum productivity and service life in the most demanding work.


Pivot Shaft

Pivot Shaft and Equalizer Bar. The pivot shaft runs through the mainframe and connects to the roller frames for independent oscillation. The full-length pivot shaft distributes impact loads throughout the case, reducing bending stresses on the case. This design eliminates alignment problems and the need for diagonal braces on the roller frames. Cat track-type tractors set the industry standard for mainframe durability. For a more comfortable ride,resilient pads cushion the oscillating equalizer bar andframe in uneven underfoot conditions. Thepinned equalizer bar gives the roller frames the ability to oscillate up or down to better match ground contours while providing maximum traction and operator comfort. Equalizer bar end pins are oil fi lled with limited slip seals forlonger life and reduced repair costs.

Pivot shaft and pinned equalizer bar oscillation system have following features:

Pivot shaft transmits ground impact loads directly to main frame.

Protects power train components.

Parts Pricing. The price of parts can impact the overall owning and operating cost of any piece of equipment. These costs are often overlooked when a purchase is being considered; however, at several points in the machines life cycle, maintenance or repair parts will be required. Like many things at Caterpillar, parts pricing is all about maximizing the bottom line of the end-user. As a result, Cat parts are priced, on average, to be competitively lower than those of the competition in the D7R size class.

Resale Value. How much will my machine be worth in three years? Five years? Ten years? At Caterpillar, weve thoroughly analyzed the market over time to provide our customers the best possible perspective.

History has proven, and continues to show, that Cat machines bring a much higher price than the competition, when resold at an auction or equipment sale. This translates into all Cat equipment owners getting a greater return on their investment than if they had purchased competitive offerings.

Global information has shown that CatTrack-Type Tractors in the 157 kW to 194kW (210hp to 260 hp) size class bring over 50percent higher price when between three and fi ve years old. That number grows to more than one-and-a-half times when the machine is between fi ve and 10 years old.

The design philosophy behind the D7R is a machine that is designed to be rebuilt, and to bring long term profi t benefi ts in ownership cash fl ow to customer operations during use, and at eventual machinedisposal.
