When purchasing a used CAT 140H, the machine’s actual condition is often more important than the original factory specification. Two CAT 140H graders of the same model can have significantly different values depending on working hours, maintenance history, hydraulic condition, tires, blade condition, transmission performance, and undercarriage or articulation components.
CAT 140H Engine and Power
Engine performance is one of the most important aspects of a motor grader because grading often requires the machine to maintain a stable working speed while simultaneously pushing, cutting, and distributing material.
The CAT 140H uses a Caterpillar diesel engine designed to provide the torque and power required for demanding grading applications.
Depending on the specific production version, the engine is generally in the 135–150 horsepower class.
The engine provides power for several critical operations, including:
- Driving the machine
- Moving material with the moldboard
- Operating hydraulic systems
- Maintaining working speed on inclines
- Performing repeated grading passes
- Supporting heavy-duty road construction work
When evaluating a used CAT 140H for sale, buyers should not focus only on the rated horsepower. Engine condition is equally important.
A professional inspection should examine:
Engine Starting Performance
The engine should start normally under appropriate conditions. Excessive cranking, unusual starting difficulty, or abnormal smoke may indicate potential mechanical or fuel-system problems.
Exhaust Smoke
Exhaust color can provide useful initial information, although it should not be used alone to diagnose an engine.
Persistent abnormal smoke may indicate problems involving fuel combustion, lubrication, turbocharging, or other engine components.
Oil and Coolant Condition
Engine oil and coolant should be inspected for abnormal contamination, leakage, or signs of overheating.
Engine Noise
Unusual knocking, excessive vibration, or abnormal mechanical noise should be investigated before purchase.
Maintenance History
Maintenance records can provide important information about oil changes, cooling-system maintenance, repairs, and replacement of major components.
For international buyers, requesting cold-start videos, engine videos, operating videos, and detailed photographs before purchasing a used motor grader can significantly improve the evaluation process.
CAT 140H Operating Weight
Operating weight is another important factor when comparing motor graders.
The CAT 140H is generally in the 14–16 tonne operating-weight class, although the actual weight depends on configuration and equipment.
Operating weight affects:
- Traction
- Stability
- Grading performance
- Transportation requirements
- Ground pressure
- Fuel consumption
- Job-site mobility
A heavier grader can provide greater stability when cutting and moving material, while the exact balance between weight and maneuverability depends on the project.
For international buyers, machine weight is also important because it affects shipping arrangements and transportation costs.
Before purchasing a used CAT 140H, buyers should confirm:
- Actual operating weight
- Tire specifications
- Optional attachments
- Blade configuration
- Additional counterweights
- Shipping dimensions
- Loading requirements
These details should be confirmed based on the actual machine rather than relying solely on general model specifications.
CAT 140H Moldboard and Grading Performance
The moldboard is the central working component of a motor grader.
The CAT 140H’s moldboard allows the operator to cut, move, spread, and shape material across the working surface.
Depending on the configuration, the moldboard is commonly around 3.7 to 4.3 meters in length.
The blade can be adjusted to perform different grading tasks.
For example, the operator can change:
- Blade angle
- Blade height
- Blade tilt
- Cutting position
- Side position
These adjustments allow a motor grader to perform a wide variety of jobs.
Road Leveling
The CAT 140H can be used to distribute aggregate and create a relatively uniform road surface.
This is particularly useful during the construction or maintenance of gravel roads.
Ditch Construction
By adjusting the blade angle and machine position, the grader can create drainage channels alongside roads.
Surface Preparation
Before paving or other construction work, motor graders can be used to prepare and level the ground.
Road Maintenance
Existing roads often require periodic reshaping because of traffic, rainfall, erosion, and material displacement. A motor grader can restore the road profile and redistribute loose material.
Hydraulic System and Blade Control
Hydraulic performance is essential for a motor grader because many of its working functions rely on hydraulic cylinders.
The hydraulic system controls important movements such as:
- Moldboard lifting
- Blade lowering
- Blade side shifting
- Blade angling
- Blade tilt
- Steering-related functions
- Articulation
When inspecting a used CAT 140H motor grader, the hydraulic system should therefore receive particular attention.
Buyers should check for:
- Hydraulic oil leaks
- Damaged hydraulic hoses
- Cylinder leakage
- Slow blade movement
- Uneven cylinder operation
- Abnormal hydraulic noise
- Excessive play in blade components
The blade should respond smoothly to operator controls.
Hydraulic cylinders should also be inspected for damaged rods, oil leakage, and excessive wear.
CAT 140H Transmission and Drivetrain
A motor grader frequently operates under changing loads. The transmission and drivetrain therefore have a direct impact on productivity.
The CAT 140H uses a powershift transmission designed for controlled movement across different working conditions.
When evaluating a used machine, buyers should check:
- Forward gears
- Reverse gears
- Gear shifting smoothness
- Transmission response
- Abnormal noise
- Braking performance
- Differential operation
- Final drives
- Axles
A practical test is often more informative than visual inspection alone.
The machine should be operated through its available gears and tested under both light and heavier working conditions where possible.
Six-Wheel Drive and Traction
Motor graders are designed differently from standard wheel loaders or excavators.
The CAT 140H uses a six-wheel-drive configuration that provides traction across the machine’s working environment.
This is particularly important when working on:
- Gravel roads
- Slopes
- Construction sites
- Uneven terrain
- Mining roads
- Soft ground conditions
Tire condition also has a direct impact on traction and operating costs.
When purchasing a used CAT 140H, inspect the tires for:
- Uneven wear
- Cracks
- Cuts
- Low tread depth
- Sidewall damage
- Mismatched tires
Replacing a complete set of large motor grader tires can represent a significant additional cost, so tire condition should be included in the purchasing assessment.
CAT 140H Applications
The versatility of the CAT 140H is one of its main advantages.
1. Road Construction
Motor graders are essential for creating accurate road profiles before subsequent construction stages.
The CAT 140H can be used for:
