How to Inspect When Purchasing Used Komatsu D21P-5

Indeed, investing in field-test models of crawler dozers from reliable brands offers a better return if handled with care. Before making a purchase, carefully inspect the machine’s critical parts and review its maintenance history. Join us for some professional tips to make your decision secure and long-lasting.

1. Verify Machine Documentation

Verify that the unit you selected is a real Komatsu D21P-5 by comparing the VIN and serial plate with the documentation. Look for a well-organized history of maintenance, such as hydraulic servicing, track adjustments, and oil changes.

There should be no liabilities or salvage designations, a clear title, and an accurate account of hours worked. Legal burdens, concealed repairs, and falsified hours are all less likely when ID and records are genuine.

2. Engine Health and Performance

Take the engine cold and note any unusual noises, vibrations, heavy smoke, or difficulty starting. Idle stability is verified if the engine starts smoothly, without grinding or fluctuating. If you experience excessive smoke, note its color.  

• Blue smoke, with a burning oil smell, shows issues in the ring or cylinder
• Black smoke: use of bad-quality fuel or a malfunction in the injector.
• White smoke: mixing of water in fuel issues with the head gasket.

Inspect the area surrounding the engine components, injectors, and pipelines for signs of leaks. Check engine oil color: heavy, dense oil is a sign of combustion problems, while milky oil suggests coolant contamination. The engine is the most costly component to repair, and its value can be significantly impacted by early wear or failure.

3. Undercarriage and Tracks

Check the Komatsu specification to ensure you selected a unit with the recommended track tension. It’s neither too tight nor too loose. Check the signs of damage on the track shoe, idlers, and connected rollers. 

The teeth of sprockets shouldn’t be very worn or jammed. There should be no mechanical stress on bushings and pins, as this indicates overloading. Poor undercarriage condition is the most significant factor influencing used crawler prices.

4. Hydraulic System

Inspect the connected pumps and controls of the hydraulic system to identify signs of malfunction and unnecessary wear. Verify the structural strength and accuracy of the cylinder seal, and assess abrasion on pipes and fittings. The color of the hydraulic fluid indicates its overall condition. For precise blade and attachment movements, a well-maintained hydraulic system is essential. 

5. Blade, Linkage, and Frame

Crawler dozers’ durable chassis and blade are equally important as their engine and other systems. Check the blade and connected hooks for excessive wear and patch welding. The edges should be sharp and corrosion-free. Excessive pressure on pivot points results from overloading and poor handling practices. 

6. Controls, Steering, and Transmission

Drivetrain responsiveness and smooth control are essential for precise grading and safe operations. Inspect the mobility and accuracy of pedals, levers, and switches for reliable operator control. Verify the strength of the brake and wheel steering under loaded conditions. The gear change should be flawless, with no jerk or slipping.

7. Cooling System and Radiator

If the radiator surface is rusted due to accumulated debris, it is a sign of poor maintenance.  The cooling system fan and belts should be in good condition for reliable performance. Likewise, the color of coolant indicates hidden issues in the engine. 

8. Electrical System and Gauges

Electrical faults may cause loss of control over dozer movement and create an occupational hazard. Inspect the connections of wiring, gauges, and external lights. The battery terminals should be clean, with no spills. 

9. Operating Hours and Wear Patterns

The actual physical condition of the used crawler dozer should correlate with its meter reading. If you find high meter readings with minimal wear on the machine or excessive wear with less usage time. It’s a red flag that indicates tampering with the meter or misreporting.

10. Test Under Load

The best way to evaluate the real condition of the crawler dozer is to take a test run, use the blade to push loads, and grade the soil to check the actual response. Change the direction of the blade and attachment repeatedly.  

11. Accessories and Consumables

A comfortable cab is equally essential for reliable productivity and job site safety. Consider the cab features, seat adjustment, climate control, and visibility factors. Ask the dealer for manuals, toolkits, and service stickers. If you noticed non-OEM parts replacements, leave this deal; it will impact compatibility or resale value.
