Common Excavator Problems and How Quality Parts Can Solve Them

Updated: Oct 24



Excavators are the backbone of many industries, from construction to mining, and keeping them operational is crucial for minimizing downtime and maximizing productivity. However, like all heavy machinery, excavators are prone to mechanical problems that can halt progress on a job site. Fortunately, many common excavator problems can be solved by using high-quality replacement parts. In this blog, we will explore some of the most frequent issues faced by excavator owners and operators, and how quality parts from reliable suppliers can be the solution.


1. Hydraulic System Leaks

One of the most common problems in excavators is hydraulic system leaks. The hydraulic system powers the boom, arm, and bucket, and any leaks can lead to reduced performance or total system failure. Hydraulic hoses, seals, and fittings are prone to wear over time, especially in rugged environments.

Solution: High-Quality Hydraulic Components

Replacing worn-out hoses, seals, and valves with high-quality OEM parts ensures a longer lifespan and better performance. Suppliers like Vikfin provide refurbished OEM hydraulic parts that meet original specifications, offering a reliable solution to hydraulic issues without the cost of brand-new components.


2. Engine Overheating

Excavators often operate in harsh conditions, causing the engine to overheat if not properly maintained. This can be due to a faulty radiator, coolant leaks, or a malfunctioning water pump. Overheating can lead to significant engine damage, which can be costly to repair.

Solution: Reliable Cooling System Parts

Ensuring the cooling system functions properly is critical to preventing engine overheating. High-quality replacement radiators, water pumps, and thermostats from reputable sources can help maintain the engine’s optimal temperature, reducing the risk of severe damage.


3. Worn Out Tracks

Excavator tracks, particularly steel tracks, endure immense pressure and wear over time. Uneven wear or broken track links can make maneuvering difficult, affecting job site productivity and operator safety.

Solution: Durable Track Parts

Investing in high-quality steel tracks or rubber tracks, depending on your machine and terrain, is essential for smooth operation. Vikfin offers used and refurbished steel tracks for 20-ton excavators, ensuring your machine stays mobile and productive.


4. Slew Ring Problems

The slew ring enables the excavator's cab to rotate 360 degrees. Over time, the slew ring can wear out due to heavy loads and frequent use, leading to grinding noises, uneven rotation, or even total failure to rotate. When this happens, the entire operational capacity of the excavator is compromised.

Solution: Refurbished Slew Rings

Replacing the slew ring with a high-quality, refurbished part can restore the full rotational capabilities of your excavator. Vikfin's stock of OEM parts, including slew rings, are thoroughly tested to ensure they meet performance standards, providing a cost-effective alternative to buying new parts.


5. Electrical System Failures

Excavators rely on complex electrical systems for everything from powering lights and sensors to controlling hydraulic components. Electrical problems, such as wiring harness failures, blown fuses, or malfunctioning sensors, can bring an entire machine to a standstill.

Solution: OEM Electrical Parts

Investing in OEM electrical components ensures compatibility and longevity. Suppliers like Vikfin specialize in providing refurbished OEM wiring harnesses, fuses, and sensors, helping to restore full functionality to the excavator's electrical system.


6. Bucket Wear and Tear

The bucket is one of the most heavily used parts of an excavator, facing constant impact, abrasion, and wear. Over time, buckets can crack or lose their teeth, reducing their efficiency and causing delays in material handling operations.

Solution: High-Quality Replacement Buckets

Instead of opting for aftermarket alternatives, which may not offer the same durability, consider replacing your worn bucket with a refurbished OEM part. Vikfin offers a range of high-quality used excavator buckets designed to withstand harsh working conditions while extending the life of your machine.


7. Final Drive Failure

The final drive powers the excavator's tracks and is essential for mobility. If the final drive starts to fail, you may notice reduced power, unusual noises, or leaking fluids. Continuing to operate the excavator in this state can cause further damage.

Solution: Quality Final Drives

To avoid costly repairs or total machine failure, replace a malfunctioning final drive with a high-quality used or refurbished part. Vikfin's range of final drives is compatible with all major excavator brands, ensuring you get the right fit for your machine.


8. Boom and Stick Cylinder Issues

The boom and stick cylinders are critical for the excavator's digging and lifting operations. Over time, these cylinders can leak or lose pressure due to seal failure or internal damage. Reduced performance in the boom or stick can lead to project delays and increased operational costs.

Solution: OEM Boom and Stick Cylinders

Replacing worn or damaged boom and stick cylinders with OEM components ensures optimal performance. Vikfin offers a wide range of used and refurbished hydraulic cylinders that meet the specifications of your machine, helping you avoid costly downtime.


9. Excessive Fuel Consumption

Fuel efficiency is a major concern for excavator operators, as fuel costs can significantly impact profitability. If your excavator is using more fuel than usual, it could be due to issues with the fuel injectors, air filters, or engine components.

Solution: Quality Engine Parts

Replacing faulty fuel injectors, clogged air filters, or other engine components with high-quality parts can improve fuel efficiency and reduce operational costs. Vikfin's range of refurbished OEM parts for excavator engines ensures you can maintain peak performance without overspending.


10. Swing Motor Failure

The swing motor controls the rotation of the excavator's upper structure. A failing swing motor can lead to erratic or complete loss of rotation, which severely limits the machine's ability to operate efficiently.

Solution: Refurbished Swing Motors

Replacing a faulty swing motor with a quality refurbished part can restore the smooth rotation of your excavator. Vikfin specializes in providing refurbished OEM swing motors that are tested for durability and performance.


Why Quality Parts Matter

The key to solving common excavator problems lies in the quality of the replacement parts you choose. While cheaper aftermarket parts may seem like a cost-saving option, they often lack the durability and precision of OEM components, leading to more frequent breakdowns and higher long-term costs.

Benefits of Choosing OEM and Refurbished Parts from Vikfin:

  • Longevity: OEM parts are designed to last, reducing the frequency of replacements.

  • Performance: Refurbished OEM parts offer the same high level of performance as new parts at a fraction of the cost.

  • Cost-Effectiveness: Vikfin's extensive range of used and refurbished parts provides significant savings without compromising on quality.

  • Expertise: Vikfin's team of experts can help you find the right part for your machine, ensuring compatibility and optimal performance.


Conclusion

Common excavator problems are an inevitable part of operating heavy machinery, but they don't have to lead to extended downtime or costly repairs. By investing in high-quality OEM and refurbished parts from trusted suppliers like Vikfin, you can keep your excavator running smoothly, reduce the frequency of breakdowns, and improve the overall efficiency of your operations. When it comes to keeping your equipment in top shape, quality parts are always worth the investment.
