# Doosan Excavator Parts: Your Top Questions Answered
Doosan excavators are renowned for their durability and performance, but like any heavy machinery, they require proper maintenance and high-quality parts to operate efficiently. Whether you’re a contractor, equipment manager, or DIY enthusiast, understanding Doosan excavator parts is crucial for keeping your machine running smoothly. In this blog, we’ll address the most frequently asked questions about Doosan excavator parts, helping you make informed decisions and optimize your equipment’s performance.
What Are the Most Common Doosan Excavator Parts That Need Replacement?
Doosan excavators are built to withstand tough conditions, but certain parts are more prone to wear and tear. The most commonly replaced parts include:
- Hydraulic Filters: Essential for maintaining hydraulic system efficiency, these filters trap contaminants and prevent damage to the system.
- Undercarriage Components: Tracks, rollers, and idlers endure significant stress and require regular inspection and replacement.
- Bucket Teeth and Cutting Edges: These parts are exposed to abrasive materials and often need replacement to maintain digging efficiency.
- Engine Components: Air filters, fuel filters, and belts are critical for engine performance and longevity.
Regularly inspecting these parts and replacing them with genuine Doosan excavator parts ensures optimal performance and reduces downtime.
How Do I Identify Genuine Doosan Excavator Parts?
Using genuine Doosan excavator parts is vital for maintaining your machine’s performance and warranty. Here’s how to identify authentic parts:
1. Check the Packaging: Genuine parts come in branded packaging with the Doosan logo and part number.
2. Verify the Part Number: Cross-check the part number with Doosan’s official catalog or website.
3. Purchase from Authorized Dealers: Always buy from authorized Doosan dealers or reputable suppliers like Kyotechs to ensure authenticity.
Counterfeit parts may seem cost-effective, but they can lead to equipment failure and costly repairs.

When purchasing online, ensure the supplier has a proven track record and offers warranties on their products.
How Often Should I Replace Doosan Excavator Parts?
The replacement frequency of Doosan excavator parts depends on usage and operating conditions. Here’s a general guideline:
- Hydraulic Filters: Replace every 500 hours or as recommended in the operator’s manual.
- Undercarriage Components: Inspect every 250 hours and replace worn parts promptly.
- Bucket Teeth and Cutting Edges: Replace when wear exceeds 50% to maintain digging efficiency.
- Engine Components: Follow the maintenance schedule in the operator’s manual, typically every 250-500 hours.
Regular maintenance and timely replacement of parts prevent unexpected breakdowns and extend your excavator’s lifespan.
What Are the Benefits of Using Genuine Doosan Excavator Parts?
Using genuine Doosan excavator parts offers several advantages:
1. Optimal Performance: Genuine parts are designed specifically for Doosan excavators, ensuring seamless compatibility and performance.
2. Durability: These parts are made from high-quality materials, offering superior durability and longevity.
3. Warranty Protection: Using genuine parts maintains your equipment’s warranty and avoids voiding it.
4. Cost Savings: While genuine parts may have a higher upfront cost, they reduce the risk of breakdowns and costly repairs in the long run.
Investing in genuine Doosan excavator parts is a smart decision for maximizing your equipment’s efficiency and lifespan.
How Can I Extend the Lifespan of My Doosan Excavator Parts?
Proper maintenance is key to extending the lifespan of your Doosan excavator parts. Follow these tips:
- Regular Inspections: Check for signs of wear and tear, such as cracks, leaks, or unusual noises.
- Timely Replacements: Replace worn parts promptly to prevent further damage.
- Proper Lubrication: Ensure all moving parts are adequately lubricated to reduce friction and wear.
- Cleanliness: Keep your excavator clean to prevent dirt and debris from causing damage.
By following these practices, you can maximize the lifespan of your Doosan excavator parts and keep your machine running smoothly.

FAQS
What are the reasons why the excavator can rotate when starting, but cannot start?
1.There is no oil in the fuel tank.
2.The fuel filter and oil-water separator are blocked.
3.The low-pressure oil circuit does not supply oil.
4.The injection pump does not pump oil.
5.There is air in the oil circuit.
6.The valve timing is misaligned. The opening time of the valve is not coordinated with the stroke of the piston in the cylinder. For example, when the piston makes a compression stroke in the cylinder, the intake and exhaust valves are open, and fresh air is driven out of the cylinder, so that there is no combustion gas in the cylinder and it cannot start.
7.The solenoid valve of the injection pump is broken and is in a closed state, and the diesel cannot enter the high-pressure chamber.

What is the reason for the cylinder pulling in the excavator engine?
Reasons from the piston group
1. The piston ring gap is too small. If the opening gap, side gap or back gap of the piston ring is too small, the piston ring will be stuck due to heat expansion when the engine is working, and it will be pressed tightly against the cylinder wall, or the piston ring will be broken, which can easily pull out grooves on the cylinder wall.
2. The piston pin is out. Because the piston pin retaining ring is not installed or falls off or breaks, the piston pin will be out during movement, which can easily damage the inner wall of the cylinder and cause the cylinder to blow into the crankcase.
3. The piston cylinder gap is too small or too large. If the piston material is poor, the manufacturing size error is too large, or the piston is deformed after the piston pin is assembled, the matching gap between the piston and the cylinder is too small, and the piston is stuck after heat expansion, which will then damage the cylinder wall.
4. The piston ring is seriously carbonized. Excessive carbon deposits cause the piston ring to stick or bite in the ring groove. At the same time, carbon deposits are a hard abrasive that will grind into longitudinal grooves on the cylinder wall.
5. The piston is seriously off-cylinder. Due to the bending and twisting of the connecting rod, the parallelism and coaxiality deviations of the connecting rod journal, main journal, and piston pin seat are too large, causing the piston to be significantly off-cylinder, which will accelerate the wear of the piston ring, piston and cylinder wall and destroy the formation of the oil film.
Reasons for cylinder sleeves
1. The roundness and cylindricality tolerances of the cylinder sleeves exceed the allowable range, which greatly reduces the sealing of the piston and cylinder sleeves. The high-temperature gas in the cylinder flows down, destroying the oil film between the piston and the cylinder wall, and then causing cylinder pulling.
2. The cylinder sleeve is deformed during the assembly process. For example: the protrusion of the upper end surface of the cylinder sleeve is too large, and the cylinder sleeve is deformed after the cylinder head is installed; the cylinder sleeve water blocking ring is too thick, and the cylinder sleeve is deformed after being pressed into the body, which can easily cause cylinder pulling.
Reasons for use:
1. Whether the size of the cylinder sleeve used during assembly does not match the cylinder body and piston.
2. The air filter is not sealed, which makes the filtering effect worse. Dust, sand and other impurities in the air are sucked into the cylinder, forming abrasive wear. Tests show that if a few grams of dust are sucked in every day, the wear of the cylinder liner will increase by more than 10 times.
Why does the hydraulic pump vibrate excessively?
Possible loose installation, unbalanced pump components, or cavitation.
Solution: Tighten installation, balance pump components, check and eliminate cavitation sources.
What to do if the hydraulic system pressure is low?
Check the hydraulic pump, pressure control valve, and hydraulic cylinders. Test the hydraulic oil for contamination or degradation, clean or replace relevant components, and ensure the hydraulic system is properly sealed.
