Power Train engine with ACERT™ Technology which is U.S. EPA Tier 3/EU Stage III compliant. Smooth, consistent shifting with fingertip control and electronic controls contribute to increased levels ease of operation and operator comfort. The new Automatic Blade Positioning (ABP) helps to improve the productivity Advanced design, materials and robotic welding contribute to increased durability and overall machine strength, pg. 7 ✓ Many convenient service...

Optional Features Operator Station and Controls straight blade, coal blade or the new service U-blade to allow for maximum productivity from your wheel dozer. ✓ Various optional features are available to meet all your needs, pg. 9 Experience a high level of productivity through Command Control steering with integrated transmission controls, fingertip blade controls, a large viewing area and spacious operator station.

Power Train Delivers top performance and durability in tough applications. Cat® C15 Engine with ACERT™ increased displacement version of the U.S. EPA Tier 3/EU Stage III compliant and features a 3.5 percent horsepower increase over the previous 3406. The four stroke engine delivers fuel economy, durability and reliability in the most demanding conditions. High torque rise delivers performance you can feel with greater rimpull, lift force and faster cycle times. Resilient engine mounts dampen vibration for lower sound levels. Engine Lubrication. Engine lubricating oil is filtered, cooled and supplied...

Torque Converter. The torque converter uses a high-capacity impeller to handle the engine's increased torque rise Heavy-Duty Axles. The fixed front and oscillating (±13 degrees) rear heavy-duty axles feature strong gears and bearings in both the differentials and heavy-duty final drives for increased durability. Permanently lubricated, maintenance- free U-j oints result in fewer parts and improved serviceability. Free floating axles shafts can be removed independently from the wheels and planetary drives. Spindles and Final Drives. Planetary units can be removed independently from the wheels...

Well-balanced hydraulics deliver precise, low-effort control and trouble-free operation. Hydraulic System. The hydraulic system provides low-effort blade control. Seat mounted levers send electrical signals to a pilot valve mounted on the front frame, moving the sound, heat and effort caused by the hydraulic valve out of the operator's station. Command Control Steering. A mechanical feedback system combines with valve ratio to provide quarter-turn, side-to- side steering. Unlike systems that rely on steering wheel velocity to activate steering cylinders, Command Control steering directly links...

Advanced design and materials provide superior strength to the purpose built structures. Structure Construction. Combines the use of robotic welding on up to 90 percent of the 824H, while castings are used in several areas to increase strength by helping to 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...

Multiple box-section construction with heat treated moldboard and DH-2 steel edges and end bits contribute to long life. Operator Controls. Lift, tilt, tip and conveniently located to the right of Applications. The 824H excels at high production dozing and spreading fill, backfilling, stockpiling, charging hoppers, maintaining haul roads and cleaning up around job sites. Blade Options. Contact your Cat® dealer for blade options and availability that include: • Straight Blade. Straight blade is used • Extended Wear Bulldozer Arrangement. The Extended Wear bulldozer arrangement is designed for...

Optional Features Available options can augment the 824H and meet your needs. Full Coverage Fenders. The front fenders extend beyond the outermost surface of the machine to prevent mud from splattering the front and side windows and to keep rocks from flying into window glass. The optional full coverage fender package includes front fenders with Full coverage rear fenders extend to the bumper, along with a rear rubber (lateral) fender extension to ensure the entire tire width is covered. Optional Counterweight. This feature is located on either side of the front frame. For each specific application,...

Operator Station and Controls Economically designed for operator comfort with low-effort controls increases efficiency

Right and Left Rear-Hinged Doors. A walk-through operator's station comes from right and left doors that can be fully opened and latched for easy entry and exit. Sound Levels. A thick, non-metallic floor, along with outside the cab hydraulics and a separated cooling system contribute to a quiet work 1 Viewing Area. The internal ROPS and bonded front glass eliminate the distracting metal frames to help increase the viewing area. The angled hood and larger windows allow the operator to see objects closer to the machine. 2 Cat® Comfort Series Seat. The six-way adjustable seat provides comfort by...

Having easy daily maintenance is the way to get it done. Caterpillar Monitoring System. Diagnostics are provided that allow technicians to review a machine's operation and quickly troubleshoot problems. Operating parameters, diagnostic codes and out-of-range gauge readings are displayed through the diagnostic connector. There are also pressure taps for easy hydraulic system checks. Service Access. Scheduled maintenance points are well within reach. A remote grease fitting is provided to lubricate the lift cylinder yoke. Removable tread plates in the platform give access to less commonly serviced...
