The hydraulic pump 708-2L-00202 whining noise in a PC210LC-7K excavator can be attributed to several factors. These include mechanical wear, fluid contamination, air trapped in the system, and misalignment of components. Regular maintenance and inspection of the hydraulic system can help identify and address these issues, ensuring optimal performance and reducing the likelihood of whining noises.
The hydraulic pump 708-2L-00202 in a PC210LC-7K excavator is a crucial component that ensures the smooth operation of the machine. However, it has been observed that this particular pump often produces a whining noise, which can be quite disruptive and potentially damaging to the machine’s performance. In this article, we will delve into the causes of this whining noise and explore possible solutions to alleviate the issue.
First and foremost, the whining noise in the hydraulic pump 708-2L-00202 can be attributed to a lack of lubrication. The pump relies on a sufficient amount of lubricant to function effectively, and when the lubricant levels are low, the pump’s internal components can grind against each other, resulting in the production of the whining noise. To address this issue, it is essential to regularly check and maintain the lubricant levels in the pump, ensuring that they are always at the recommended levels.
Another potential cause of the whining noise is the presence of air in the hydraulic system. Air bubbles can become trapped within the pump, causing it to work less efficiently and produce the unwanted noise. To resolve this issue, it is necessary to bleed the system, which involves releasing the trapped air and allowing the hydraulic fluid to flow freely through the pump. This can be done by following the manufacturer’s guidelines for bleeding the system, which can typically be found in the machine’s manual.
Wear and tear on the pump’s internal components can also lead to the production of the whining noise. Over time, the pump’s components can become worn down and less effective, causing the pump to work harder and produce the unwanted noise. In such cases, it may be necessary to replace the worn components or even the entire pump to restore the machine’s performance. Regular maintenance and inspection of the pump can help identify any wear and tear issues before they become severe.

The hydraulic pump 708-2L-00202 in a PC210LC-7K excavator is a crucial component that plays a vital role in the smooth operation of the machine. However, it is not uncommon for this pump to produce a whining noise, which can be quite disruptive and potentially indicate a problem with the pump itself. In this article, we will delve into the causes of this whining noise and discuss some preventive measures that can be taken to avoid such issues in the future.
First and foremost, it is essential to understand the primary function of the hydraulic pump 708-2L-00202 in the PC210LC-7K excavator. This pump is responsible for transferring hydraulic fluid from the reservoir to the various actuators, such as the boom, arm, and bucket cylinders, as well as the travel motors. The pump operates at a high pressure, which enables the excavator to perform its tasks efficiently and effectively.
Now, let us explore some of the potential causes of the whining noise in the hydraulic pump 708-2L-00202:
1. Worn or damaged bearings: One of the most common causes of whining noise in a hydraulic pump is the presence of worn or damaged bearings. Over time, the bearings can become worn due to friction and heat, which can lead to a loss of lubrication and the generation of noise. Regular inspection and maintenance of the bearings can help prevent this issue from occurring.
2. Contaminated hydraulic fluid: Contamination of the hydraulic fluid can also lead to whining noise in the pump. Debris, such as dirt, dust, and metal shavings, can enter the system and cause abrasive wear on the internal components of the pump. To prevent this, it is crucial to regularly change the hydraulic fluid and filter it to remove any contaminants.
3. Misalignment of pump and motor: If the hydraulic pump and motor are not properly aligned, it can cause excessive wear on the shafts and bearings, leading to whining noise. Proper alignment of these components is essential to ensure smooth operation and prevent premature failure.
4. Cavitation: Cavitation occurs when the hydraulic fluid is not adequately supplied to the pump, causing the formation of vapor pockets or cavities. This can lead to a whining noise as the pump struggles to generate the necessary pressure. Ensuring that the hydraulic system is adequately sized and that the fluid is flowing correctly can help prevent cavitation.
To avoid whining noise in the hydraulic pump 708-2L-00202 in a PC210LC-7K excavator, the following preventive measures can be taken:
1. Regular inspection and maintenance: Routine inspection and maintenance of the hydraulic system, including the pump, can help identify any potential issues before they become severe. This includes checking the bearings, filters, and hydraulic fluid levels regularly.
2. Proper alignment of pump and motor: Ensuring that the hydraulic pump and motor are correctly aligned can help prevent excessive wear and noise.
3. Clean and replace hydraulic fluid: Regularly changing and filtering the hydraulic fluid can help maintain a clean and contaminant-free system, which can prevent whining noise caused by contamination.
4. Use high-quality components: Using high-quality components, such as bearings and seals, can help ensure that the hydraulic pump operates efficiently and quietly.
In conclusion, understanding the causes of whining noise in the hydraulic pump 708-2L-00202 in a PC210LC-7K excavator is essential for preventing potential issues and maintaining the smooth operation of the machine. By implementing regular inspection and maintenance, proper alignment, clean hydraulic fluid, and high-quality components, it is possible to avoid whining noise and ensure the longevity of the hydraulic pump.
