Used Motor Grader CAT 140H Main Parts Pictures

The Caterpillar 140H Motor Grader is another popular model used for grading and earthmoving operations. It is part of the Caterpillar 140-series graders and is equipped with advanced features for better performance and efficiency. Below are the main parts of the Caterpillar 140H Motor Grader:

1. Engine

• Engine Type: The 140H is typically powered by a Caterpillar 3306B or 3306DI engine. It delivers the required horsepower for the grader's operations, including efficient fuel consumption and high power output.
• Engine Components: Key components include the air intake, exhaust, fuel system, cooling system, and filtration system (oil, fuel, and air).

2. Transmission

• The 140H is equipped with a Power Shift Transmission. It typically includes 6 forward gears and 3 reverse gears, allowing the operator to change speed without the use of a clutch.
• The transmission helps provide smooth shifting, better traction, and more efficient power delivery.

3. Frame

• The frame is the primary structure of the motor grader. It supports the engine, transmission, axles, and blade. The frame must withstand significant stress and force during operation.

4. Hydraulic System

• The hydraulic system in the 140H is used to control the blade, raise and lower the machine, and perform other essential functions. It includes hydraulic cylinders, pumps, hoses, and a hydraulic oil reservoir.
• The hydraulic system is designed for high efficiency and durability in demanding applications.

5. Blade (Moldboard)

• The moldboard is the main working component of the motor grader. It can be adjusted for height, angle, and tilt, and is typically around 12 feet in length.
• The blade is responsible for the cutting, leveling, and grading of the surface.

6. Circle and Swivel

• The circle is the rotating mechanism that allows the moldboard to rotate horizontally, adjusting the blade’s position. The swivel is responsible for the angular movement of the blade, making it versatile in various grading tasks.

7. Cab

• The operator’s cab houses the control systems and provides the operator with visibility and comfort. It includes ergonomic seating, joystick controls, air conditioning, and various monitoring systems to keep track of the machine’s performance.
• The cab is designed for enhanced safety and convenience, with a clear view of the work area and easy access to all controls.

8. Articulating Steering

• The 140H features an articulated steering system. This allows the grader to maneuver in tight spaces by enabling the front and rear sections to pivot independently.
• This system gives the operator excellent control over the grader’s direction and movement, particularly in confined spaces or on winding roads.

9. Axles

• The front and rear axles of the 140H motor grader provide support and mobility. The front axle typically steers the machine, while the rear axle supports the blade’s weight.
• The axles are designed to handle the stresses of grading and provide stable traction on various surfaces.

10. Tires

• The 140H is usually fitted with large radial tires that provide good traction and stability, essential for grading operations on rough terrain.
• The tires need to be durable and provide enough grip to move the grader efficiently while minimizing damage to the working surface.

11. Rear Ripper (Optional)

• The rear ripper is an optional attachment that can be added to the 140H motor grader. It features ripper shanks that can be lowered into the ground to break up hard soil or rock before grading.
• This attachment is useful for tasks like road preparation, mining, and working with difficult ground conditions.

12. Cooling System

• The cooling system includes a radiator, fans, and thermostats that help keep the engine and hydraulic systems within optimal operating temperatures.
• The system is designed for heavy-duty use and ensures that the motor grader does not overheat during extended operations.

13. Fuel System

• The fuel system consists of the fuel tank, fuel pump, fuel filters, and fuel lines. It ensures that the engine gets the proper amount of fuel needed for combustion.

14. Braking System

• The 140H uses an oil-cooled braking system with disc brakes for both service and parking. The system is designed to provide high braking efficiency and control.
• It ensures safety during operation and when bringing the machine to a complete stop.

15. Electrical System

• The electrical system includes wiring, alternator, battery, lights, and sensors that help power the grader’s various electrical components.
• It powers features like the operator’s dashboard, lights, air conditioning, and other electrical systems that support the grader’s operation.

16. Steering System

• The hydraulic steering system allows precise control over the grader’s movement and turns, making it highly maneuverable even in confined spaces.

17. Lift and Tilt Mechanism

• The 140H includes a lift and tilt mechanism for controlling the moldboard’s height and angle of operation. This is essential for precise grading and surface leveling.

18. Front Blade (Optional)

• Some models of the 140H may come with a front blade, which can be used for tasks like snow removal or pushing materials. The blade can be raised, lowered, and tilted using hydraulic controls.

These are the main parts of the Caterpillar 140H Motor Grader. Each part plays a crucial role in ensuring the machine operates efficiently, providing precise grading, leveling, and earthmoving capabilities. The 140H is known for its durability and ability to perform heavy-duty work in various applications, from road construction to land leveling.
