Benefits & Features
Power Train
Cat 3412E Engine
The Cat 3412E engine, with the hydraulically actuated, electronically controlled unit injector fuel system (HEUI), offers superior lugging performance, fuel efficiency and reliability.
Superior Lugging Performance
High torque output and high torque rise makes the 3412E engine very responsive.
HEUI Fuel System
The HEUI system uses hydraulically actuated, electronically controlled unit injectors to pressurize and inject fuel, providing the optimal mix of fuel and air.
Electronic Engine Control
Electronic speed governing, active & logged diagnostics code, cold start-up mode, low oil pressure warning/derate & high coolant temperature warning/derate are some features added to provide efficient & productive engine operation.
Engine Life
The large bore-stroke design and conservative power rating help minimize internal stresses and increase component life.
Ether Starting Aid
Ether starting aid comes standard on the 24H to help ensure engine starting in the extreme cold.
Power Shift Transmission
Caterpillar designs and builds transmissions specifically for Cat motor graders.
Gear Selections
Six forward speeds and three reverse speeds give the operator a wide operating range.
Torque Converter
The lockup clutch torque converter permits the machine to operate in direct drive for more efficient operation at higher torque converter output speeds.
Planetary Design
Balanced planetary transmission with large diameter oil-clutch packs provides superior load distribution and heat dissipation, resulting in longer transmission life.
Control Valves
Designed and manufactured by Caterpillar, control valves provide smooth, yet firm, engagement of direction and speed clutches.
Transmission Neutralizer
The transmission neutralizer is available to disengage power to the wheels.
Oil-Disc Brakes
Caterpillar designs and builds multi-disc brakes that are completely sealed and adjustment-free.
Parking Brake
The parking brake is spring-applied and oil released.
Hydraulics
Power On Demand
Normally, the variable displacement pump idles at near-zero output.
Control Valves
Control valves are designed and built by Caterpillar specifically for motor graders.
Secondary Steering
Secondary steering provides hydraulic oil flow, via a ground-driven pump, to the steering system if the engine fails or main hydraulic pump flow is lost while the machine is operating.
Operator Effort
Controls are designed to reduce operator fatigue.
Balanced Flow
When the operator uses several controls at one time, flow is proportioned to ensure all implements can operate simultaneously.
Independent Oil Supply
A large independent oil supply prevents cross-contamination and provides proper oil cooling, which means less heat build-up and longer component life.
Drawbar, Circle and Moldboard
Rugged Construction
The drawbar features an A-frame, box section design for high strength.
Tall Moldboard
Tall moldboard and large throat clearance help move material more quickly and efficiently.
Yoke Plate
Full-length yoke plate gives strength, support and protection to the circle.
Replaceable Wear Items
Replaceable wear inserts are located between the drawbar and circle and between the eight support shoes and circle.
Protection Systems
To relieve high-impact loads, Caterpillar provides two protection systems as standard equipment.
Operator's Station
Viewing Area
The exceptional viewing area helps improve operator confidence and productivity in all grader applications.
Quiet Cab
The quiet environment keeps the operator alert and focused.
Comfort
Low efforts on all pedals, hydraulic controls and the transmission shifter reduce operator strain and fatigue.
Roomy Interior
Extra leg and foot room create a spacious, open cab.
Seat
Contour series suspension seat is standard equipment and features fold-up armrests and a retractable seat belt.
Climate Control
Standard air conditioner and heater arrangements create a comfortable work environment for the operator.
Electronic Monitoring System
The Electronic Monitoring System checks important machine systems and provides the operator with three levels of warnings.
Features
Comfort and convenience are designed into every feature.
Serviceability
Easy Access
Easy access to service areas speeds up maintenance and ensures that routine service is performed on time.
Power Train Components
Power train components feature a modular design so you can remove the engine, transmission or final drives independently for quicker servicing.
Diagnostic Capability
A diagnostic tool connection plug allows the starting-charging system to be checked quickly and easily.
XT Hose
Caterpillar designs and manufactures its own heavy-duty XT hose and installs it in all high-pressure circuits. Its resistance to abrasions, coupled with its exceptional strength and flexibility, helps minimize maintenance and extend life.
O-Ring Face Seals
O-Ring face seals create a reliable seal and are used in all hydraulic circuits to minimize the possibility of oil leaks.
Wiring Harnesses
Separate wiring harnesses connect all electrical components.
Environmentally Responsible Design
Quiet Cab
High-contact ratio gears in the transmission and slower engine speeds transmit less noise and vibration to the operator.
Quiet Machine
This quiet operation enables the machine to work with minimal disturbance to the surrounding environment.
Dry Machine
Lubricant fill points and filters are designed to minimize spillage.
O-Zone Protection
R134a refrigerant is used in the air conditioning unit to address environmental concerns.
