Used Motor Grader CAT 140K Main Parts Pictures

The Caterpillar 140K Motor Grader is a versatile piece of construction equipment, commonly used for grading and leveling surfaces. Below are the main parts of a Caterpillar 140K Motor Grader:

1. Engine

• Engine Type: The 140K is typically powered by a Cat C7.1 ACERT engine. It provides the necessary power to drive the motor grader and perform heavy tasks.
• Engine Components: Includes air filters, fuel filters, cooling system, and exhaust system.

2. Transmission

• Power Shift Transmission: The transmission allows the operator to shift gears without using a clutch, providing smoother operation. The 140K has a 6-speed forward and 3-speed reverse transmission.

3. Frame

• The frame is the backbone of the motor grader, providing structural integrity and support to all other components. It holds the engine, transmission, and other key parts in place.

4. Hydraulic System

• Hydraulic Pumps and Cylinders: The motor grader uses a hydraulic system to control the blade's movement and tilt, as well as to raise or lower the machine. Hydraulic pumps and cylinders are critical for precise operations.
• Tank and Fluid: A hydraulic tank stores the hydraulic fluid, which is circulated through the system.

5. Blade

• Moldboard: The blade is the key working part of the grader. It can be adjusted for height, tilt, and angle, depending on the task. The 140K features a 12-14 ft moldboard, which can be adjusted to achieve different cuts and grades.
• End Bits: These are the cutting edges at the end of the blade, which can be replaced as they wear out.

6. Circle and Swivel

• The circle is the large, rotating part that allows the blade to be adjusted horizontally. The swivel is the mechanism that allows the blade to rotate around its center, making it highly versatile for different types of grading work.

7. Cab

• The cab is the operator's workstation. It includes controls for the engine, transmission, hydraulics, and the blade, as well as visibility features for the operator to see the work area clearly.
• Seats and Controls: The cab is equipped with ergonomic seats, joystick controls, and an intuitive display panel that gives real-time information about the machine's operation.

8. Articulating Steering

• The 140K features a hydrostatic articulating steering system, which allows the grader to make precise turns by articulating the front and rear sections of the machine. This system provides flexibility in tight spaces.

9. Axles

• The front and rear axles allow the motor grader to move, with the front axle being responsible for steering. These axles are designed to handle the weight and stress of the grader's operations.

10. Tires

• The motor grader typically uses large radial tires, which provide good traction and stability on various surfaces.

11. Rear Ripper (Optional)

• The rear ripper is an optional attachment that is used to break up tough ground or material before grading. It consists of one or more ripper shanks that can be lowered into the ground.

12. Cooling System

• The cooling system includes radiators, fans, and thermostats that help maintain the optimal operating temperature for the engine and hydraulic systems.

13. Fuel System

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

14. Braking System

• The 140K has an oil-cooled braking system that includes disc brakes and parking brakes. It ensures that the motor grader can be safely stopped during operation.

15. Electrical System

• This includes the wiring, alternator, starter motor, and battery that power the electrical components of the grader, including the lights, instrument panel, and various sensors.
