When purchasing a used excavator or even a new one, encountering faults and problems is almost inevitable over time. For used excavators, the likelihood of breakdowns depends on various factors, including how long they’ve been in use and the environments they operate in. Since you’ve chosen a used excavator, it’s essential to not only focus on regular maintenance but also understand how to address common issues and estimate repair costs. Several factors impact the cost of repairs, such as the availability of skilled technicians in the area. Many buyers opt for private repair services to cut costs when it comes to spare parts and maintenance.
1. Common Issues and Major Repair Costs
The cost of repairing an excavator typically depends on the brand, model, and choice of parts. Parts from well-known brands are often expensive, and the model—whether it’s a large or small excavator—also plays a role, as larger machines tend to have higher repair costs due to the size of their components. Additionally, third-party parts are often cheaper than those from official channels, but they vary widely in quality. It’s essential to do thorough research before purchasing.
Engine Repairs: The engine accounts for the largest portion of an excavator’s repair costs. Both repairs and replacements are expensive. Engine failures are commonly caused by wear and tear over time. In many cases, replacing internal components can resolve the issue.
Hydraulic Pump Issues: The hydraulic pump tends to have a slightly higher failure rate than the engine. This is mainly due to poor hydraulic oil quality or overloading the excavator over extended periods. Hydraulic pump prices vary significantly depending on the excavator type. In the second-hand market, used or non-OEM pumps can be more affordable, though they may not match the original in performance or lifespan. However, the low price makes them a practical option.
Wearable Parts: Tracks, bushings, rollers, and idlers are components that frequently come into contact with the ground and are prone to wear. These parts are generally inexpensive, and replacement costs are lower. However, there are quality differences between brands, so choosing parts based on your specific work environment can help reduce costs. Similarly, damage to components like the boom, bucket, and arm—such as cracks or deformations—can typically be repaired or replaced without too much difficulty.
Electrical and Hydraulic System Failures: These issues usually stem from aging, physical damage, or water and foreign particles entering the system. Hydraulic system repairs are generally straightforward, but the electrical systems in newer models can be quite complex and often require professional technicians. Basic component wear and tear is relatively inexpensive to repair. In some cases, minor issues that don’t affect safety or performance can be left untreated, reducing overall repair costs.
2. How to Reduce Repair Costs
To keep repair costs manageable with a used excavator, preventative maintenance is key. Developing good habits, such as inspecting key areas before and after each use, can help catch issues early. Choosing a well-known brand not only ensures excellent performance but also tends to result in fewer breakdowns. High-end brands generally offer better user experiences and lower fault rates.
In addition to regular maintenance, you can reduce repair costs by using extended warranty services or insurance. For instance, Tiedou offers warranties ranging from 3 to 6 months covering five types of repairs for their used excavators. They also provide lifetime global logistics services for spare parts, which is especially helpful in remote areas where sourcing parts can be challenging.
When purchasing a used excavator, it's important to choose a reputable and trustworthy brand. Partnering with a reliable seller ensures that the machine has undergone proper inspections and maintenance, minimizing the potential for issues. This way, a high-performing excavator can be delivered to customers without hidden problems.
In summary, understanding the common issues and repair costs of used excavators allows you to plan ahead and manage maintenance effectively. Whether you rely on local technicians, opt for third-party parts, or invest in extended warranties, being proactive can significantly reduce long-term expenses and improve the reliability of your equipment.
