Power Train

Cat® C9 ACERT Engine
Delivers, at a rated speed of 2,100 rpm, net power of 173 kW (232 hp) and meets the U.S. Environmental Protection Agency Tier 3 emissions regulations and Stage IIIA EU Emissions Directive 97/68/EC. With high horsepower and low displacement, this innovative engine provides excellent fuel economy and durability which can significantly reduce operating costs.

Torque Rise
Is increased as a result of the electronically controlled, computer-actuated unit injection fuel system that provides high injection pressure and more precisely controlled fuel delivery as the engine lugs back from rated speed.

ADEM™ IV Fuel System
Is a Caterpillar electronic control module which provides improved engine response, performance, fuel efficiency, troubleshooting diagnostics and reduced emissions. It allows integration with the electronic transmission control for maximum power train efficiency.

Packs more dense air into the cylinders for more complete combustion and lower emissions, improving performance and engine efficiency. These benefits are especially useful at high altitudes.

Air-to-Air Aftercooler
Reduces smoke and emissions by providing cooler inlet air for more efficient combustion. This also extends the life of the piston rings and bore.

Dual Cooling Jets
In the block spray oil on the piston skirt and cylinder bores keep ring temperatures low for long ring and liner life with excellent oil control.

Are two piece articulated-type with forged steel crowns for excellent strength and aluminum skirts for reduced weight. The pistons are oil cooled for increased heat dissipation and longer life.

Four per cylinder allow for good air flow, enhancing fuel efficiency and heat rejection. Valves and unit injection system are camshaft-actuated for precise timing.

Is steel-forged, carburized and induction-hardened for long-term durability. It is dynamically balanced for smooth operation. The crankshaft is completely regrindable, and the connecting rods can be removed through the tops of the cylinders for easy servicing.

Cat Engine Oil
Is formulated to optimize engine life and performance and is strongly recommended for use in Cat diesel engines. Engine oil change interval is 500 hours.

Cat Remanufactured Parts
Are available, along with dealer proposed repair options, which increase machine availability and reduce total repair costs.

Cat Planetary Powershift Transmission
Features heavy-duty components to handle tough jobs. The 345.4 mm (13.6 in) planet drives operate in all gears, forward and reverse. The addition of Electronic Clutch Pressure Control (ECPC) contributes to improved shift quality, reduced torque spikes and overall transmission durability.

Heavy-Duty Axles and Brakes
Are designed to last in all kinds of operating conditions. Two front axle disc brakes provide improved braking capability and better heat dissipation. Planetary final drives use free-floating, bronze sleeve bearings in the planet gears.• Oil disc brakes are adjustment-free and fully enclosed to lock out contaminants.

Heavy-Duty Axles and Brakes

Front Axle
Is rigidly mounted to the frame to support the weight of the compactor, internal torque loads and external loads applied during compacting and dozing operations.

Rear Axle
Includes a trunnion, two trunnion supports and associated bearings, allowing it to oscillate plus or minus 12 degrees.

Four Piece Axle
Contains two axle shaft housings - the center housing and the intermediate housing. Features and benefits of this design include:• Inboard brakes on the front axle only are positioned immediately adjacent to the differential and operate on the low torque side of the final drive, requiring less braking to stop the machine.


Structure Construction
Combines the use of robotic welding on up to 90 percent of the 815F Series 2 with castings in several areas to increase strength by helping spread the loads and reduce the number of parts. This provides highly consistent welds with deep plate penetration and excellent plate fusion. The benefits are increased durability and fatigue strength. The computer controlled machining ensures the alignment of pin bore, axle pad, cab mount and transmission/engine components.

Box Section Engine Frame
Designed to resist twisting and torsional forces, the box section engine end frame provides a solid foundation for the axles, engine and transmission.

Front Frame
With two plates provides maximum structural strength during compaction and dozing applications.

Spread Hitch Design
Improves load distribution by reducing loads to the hitch bearings. The large center hitch design improves hydraulic line routing and makes service access easier.

Upper and Lower Hitch Pins
Pivot on double-tapered roller bearings. Box-style sections in the hitch pins and crossmember assembly improve frame structure strength. Increased diameter lower hitch pins add to the robust design.

Engine and Transmission Mounts
With rubber isolation mount design reduces noise and vibration.

Operator Station and Controls

1 Exceptional All-Around Viewing Area
Reduces strain and fatigue, making operators more productive.

2 Caterpillar® Monitoring System
With electronic analog gauges is a highly effective and reliable warning and diagnostic system.As a warning system, it constantly checks machine functions and tells the operator when there is a problem. Easy-to-read gauges display fuel level, temperatures for engine coolant, transmission and hydraulic oil, engine rpm and gear range. Hour meter, odometer and analog tachometer readings are also displayed.As a diagnostic system, it identifies conditions, shows current readings and plays back maximum or highest readings registered during recent operations.The right side panel contains a three level warning system, providing full-time monitoring of key functions. The system alerts the operator of immediate or impending problems with air inlet temperature, brake oil pressure, electrical system, low voltage, engine oil pressure, engine over-speed, fuel filter status, parking brake status, steering oil pressure and transmission filter status.

3 Quick Gear Kick Up/Down Button
Allows the operator easily downshift or upshift to a different gear. It is a convenient way to shift that saves time and effort.

4 Ignition Key Start/Stop Switch
Is positioned for easy machine starting and stopping.

5 12-Volt Power Supply and Electronic Technician (Cat ET) Diagnostics
Is provided inside the cab for powering radios, telephones or a laptop computer. This is particularly useful for powering a laptop running Cat ET to access the enhanced engine and transmission control system diagnostics.

6 Steering Column
Adjusts to multiple positions. The leather-like steering wheel and transmission control provide a sure grip and comfortable feel. The horn is conveniently located in the center of the steering wheel.

7 Pilot-Operated Blade Controls
Are conveniently located and allow for precise blade movement.

8 Operator Seat
Is designed for comfort and support. Seat cushions reduce pressure on the lower back and thighs while allowing unrestricted arm and leg movement.• A fully adjustable air suspension seat with self-contained compressor is available as an option.

9 Built-In Storage Space
Is designed to hold cups, lunch box, insulated bottle and personal items.

10 Repositioned Vents
Throughout the cab keep fresh air flowing while improving the cab's heating, cooling, defrost and defog capability.

11 Throttle Lock
Allows an operator to set the engine speed and remove his foot from the governor (accelerator) pedal much like cruise control on an automobile. Using this feature increases productivity, fuel efficiency and improves operator comfort.

12 Decelerator Pedal
On the left acts as both an engine decelerator and a brake that overrides the engine speed selected by the throttle lock. This enables the operator to slow down when throttle lock is engaged and to return to throttle lock without pressing a button. It aids in maneuvering around scrapers, haul trucks, tractors or any other obstacle.

13 Windshield Washers/Wipers
With in-the-blade washer delivery system are standard features on front and rear windows. The front wiper has intermittent speed capability.

14 Rear Vision Camera Monitor
Connected to a camera mounted on the radiator guard, this monitor allows the operator to see the area behind the machine.

Tamping Wheels and Tips

Wheel Design
Gives the operator four-wheel width coverage in just two passes with front and rear wheel tracking that eliminates gaps and overlaps.

Chevron Tamping Wheel Tip Design
Is used for equal compaction in forward or reverse. Tips are full perimeter and are replaceable. The tip is welded to a base assembly, which is then welded directly to the drum. There are 12 tips per row and 60 tips per wheel for excellent compaction.

Symmetrical Tamping Wheel Tip Pattern
Has a modified chevron tamping wheel tip design to provide greater ground pressure, more compaction, a smooth ride and excellent traction. Tip height is 190 mm (7.5 in) and width is 168 mm (6.6 in).

Symmetrical Tamping Wheel Tip Pattern

Cleaner Bars
Help keep the drums free of carry-over dirt regardless of rolling direction. A pass-through bolt design allows for easier serviceability.

Cleaner Bars

Adjustable Cleaner Bar Tip
Are constructed from cutting edge steel that is heat treated and direct hardened, which increases the wear life and translates into lower operating costs.

Is achieved from the bottom of the lift to the top. The tapered pads walk out of the lift without "fluffing" the soil. The top of the lift is compacted and the surface is relatively smooth and sealed so hauling units are able to maintain a high speed when traveling over the fill. 815F Series 2 travel speed allows for four forces of compaction: pressure, manipulation, impact and vibration. Since it can also spread fill, the number of spreader tractors may be able to be reduced.



Blade Package
Consists of the blade, push-arms, trunnion mounting, dozer-length skid plate with replaceable wear plates, reversible cutting edges, self-sharpening end bits, hydraulic lines guard and hydraulic lift cylinders.

Operator Controls
The tilt cylinder is an option that gives the 815F Series 2 more versatility when dozing. The controls are seat-mounted and located in a convenient location to the right of the operator.

Outside Mounted Straight Blade
With multiple box section construction includes a heat treated moldboard and DH-2™ steel cutting edges and end bits for long life. The outside mounting is a stronger design because stresses are put on the frame rather than the blade so blade flexing is reduced. It also allows for higher lift and a wider blade can be used than with an inside mounted design.

Outside Mounted Straight Blade

The 815F Series 2 excels at compacting, spreading fill, backfilling and boosting scrapers. With the ability to work at higher speeds over other types of soil compactors, the 815F Series 2 can keep up with a fast-moving scraper fleet or an articulated truck hauling operation. When speed and dozing capability are required job duties for a soil compactor, the 815F Series 2 has no equal.


Optional Features

Rear Vision Camera
Uses a camera mounted on the radiator guard and a monitor in the cab to allow the operator to see the area directly behind the machine.

Air Suspension Seat
Provides added comfort for the operator so productivity stays high.

Air Conditioner
Uses blended air and R134a refrigerant for immediate temperature changes.

Several radio options are available factory installed: AM/FM CD or AM/FM CD with satellite radio (a service contract is required from a satellite radio provider).

Product Link
Allows the customer and/or dealer to monitor the machine from a remote location.

Rear No-SPIN Differential
Replaces the rear standard differential. It delivers maximum traction in low traction or inconsistent ground conditions.

Fast Fill Adapter
Used during peak periods when high production is needed and little down time can be afforded for fueling. Fuel is pumped into the tank through a filling nozzle at rates up to 378.5 liters (100 gallons) per minute. As fuel enters the tank, air is forced out through an open vent. When the tank is full, the vent closes and the filling nozzle automatically shuts off.

High Speed Oil Change
Uses an evacuation system to speed up the engine oil change which helps to reduce the service time.

Turbine Pre-Cleaner Group
Replaces the standard stratatube air cleaner with a turbine-style air intake cleaner which is useful in dry, dusty work conditions.

Heavy Duty Cleaner Bar Tips
The shape of these tips enables them to penetrate the wheel more efficiently than the standard cleaner bar tips, thereby reducing wheel drag and improving machine performance. Constructed from cutting edge steel used for blades and buckets, this high alloy steel is heat treated and direct hardened, which increases tip wear life by up to 240 percent over other designs in sticky, abrasive soil applications.

High Intensity Discharge (HID) Lights
Adds four lights on the cab and two on the radiator guard to brighten up the work area. HID lights are two times brighter than the standard halogen lights.Note: These lights will be available mid-2007.
