Troubleshooting Common Hydraulic Pump Issues
Problem: Hydraulic Pump Cavitation in a Caterpillar CAT Excavator
Description: Cavitation in a hydraulic pump occurs when air bubbles form and collapse within the pump, often due to insufficient fluid supply or restrictions in the suction line. This can lead to noisy operation, reduced pump efficiency, and potential damage to the pump components in Caterpillar CAT excavators like the 320D or 336E.
Symptoms:
Loud, knocking or rattling noise from the hydraulic pump.
Milky or foamy hydraulic fluid.
Reduced hydraulic system performance, such as slow or weak cylinder movement.
Overheating of the hydraulic pump.
Troubleshooting and Solution:
Check Hydraulic Fluid Level: Low fluid level is a primary cause of cavitation. Ensure the hydraulic fluid reservoir is filled to the correct level as per the Caterpillar CAT excavator's service manual.
Inspect Suction Line: Examine the suction line (the hose or pipe leading to the pump inlet) for any restrictions, kinks, or collapses. Replace any damaged sections. Ensure hose clamps are tight and there are no air leaks.
Filter Inspection: Clogged suction filters or strainers can restrict fluid flow. Check and replace the suction filter if it is dirty or overdue for replacement. Refer to the maintenance schedule for recommended filter change intervals.
Fluid Condition: Contaminated or old hydraulic fluid can contribute to cavitation. Check the fluid for contamination, water ingress, or degradation. Consider a hydraulic fluid flush and replacement if necessary.
System Bleeding: Air trapped in the hydraulic system can cause cavitation. Bleed the hydraulic system according to the Caterpillar CAT excavator's service manual to remove trapped air.
Pump Inlet Pressure Check: Use a pressure gauge to check the inlet pressure at the hydraulic pump. Low inlet pressure indicates a suction restriction problem.
Professional Inspection: If the issue persists after checking the above points, the hydraulic pump itself might be damaged or worn. Consult a qualified hydraulic technician to inspect the pump and system for internal damage or wear. Consider replacing the hydraulic pump if necessary, such as using a high-quality aftermarket Hydraulic Pump 524-0924 for Caterpillar CAT C9.3B or C13 Excavators from Growshine International.
