This Caterpillar 140H is a used motor grader — sometimes referred to as a road grader or grading machine — a self-propelled piece of construction and road-building equipment used to level, shape, and finish earthen or gravel surfaces, cut drainage ditches, and prepare road bases prior to surfacing. Caterpillar is one of the world's most widely recognised manufacturers of heavy construction, mining, and earthmoving machinery, with a long-established reputation for producing durable equipment used across civil engineering, road construction, and infrastructure projects globally. This example was manufactured in 1998 and is located in South Africa.
The machine has undergone a substantial programme of mechanical attention and reconditioning. The engine has been overhauled, representing a significant investment in the longevity and reliability of the powertrain. New fuel injectors have been fitted as part of this engine work. The front axle has received new king pin and bush components, addressing a critical wear point on motor graders that directly affects steering precision and front-end stability. New tie rod ends have also been installed, further restoring the integrity of the steering assembly.
Hydraulic system work is extensive. All hydraulic cylinder seals have been renewed throughout the machine, and both control valve assemblies have been serviced. The slew ring motor — which controls the rotation of the circle and blade assembly, central to the grader's ability to angle and position its blade — has also been serviced. The transmission pump has been serviced as well, supporting reliable power delivery to the drivetrain.
Completing the refurbishment, the machine has been fitted with a new set of tyres across all wheel positions.
