5 Signs of a Bad Hydraulic Pump

5 Signs of a Bad Hydraulic Pump

Having the ability to anticipate potential issues in hydraulic pumps can greatly benefit operations, preventing unpreparedness and severe malfunctions. To help you identify red flags of hydraulic pump failure, follow these guidelines. If you encounter any of these warning signs, don't hesitate to seek assistance from local experts in diesel engine repair:

  1. Interior Leaks - Hydraulic fluids should remain contained within their designated tubes. If you observe any liquids elsewhere inside the pump, it indicates a problem. This could be due to a broken line or loose seal valve. Promptly inspect your pump to detect and address this issue. If necessary, consult a technician specialized in diesel engine repair for further evaluation.

  2. Exterior Leaks - Exterior leaks are a progression of interior leaks and signify a worsened situation. These leaks lead to reduced system pressure and demand immediate servicing or pump replacement. Engage with an expert in diesel engine repair to assess the extent of repairs required.

  3. Abnormal Noises - Unusual sounds from your hydraulic system indicate an underlying problem. Hydraulic systems are designed to minimize noise, so any loud banging or knocking sounds are concerning. These noises may be a result of air-contaminated hydraulic fluid or insufficient fluid levels. Investigate the cause and seek professional assistance as needed.

  4. Elevated Temperatures - Proper heat dissipation is crucial for hydraulic systems to function effectively. Accumulated dirt and debris in the system can hinder heat dissipation, leading to excessively high hydraulic fluid temperatures. Elevated temperatures can damage seals and the fluid itself. If your system operates above 180°F, promptly address the issue. Inspect the heat exchanger for airflow obstructions and take corrective measures.

  5. Slow Performance - Slower operations or extended cycles may indicate a malfunctioning hydraulic pump. Pay attention to decreased efficiency, as it may signify a lack of flow within the system. Consult with a diesel engine repair professional to identify the root cause and find appropriate solutions.

By being vigilant and recognizing these warning signs, you can proactively address hydraulic pump issues and ensure the smooth operation of your equipment. Seeking assistance from knowledgeable experts in diesel engine repair is vital in promptly resolving any detected problems.
