FAQ1: How to identify worn needle roller bearings in oil pumps?
Identifying worn needle roller bearings in an excavator oil pump is crucial for preventing a complete pump failure. Look for the following signs:
Unusual Noise: A grinding, whining, or rattling noise coming from the pump is a common sign of a worn bearing.
Excessive Heat: The pump housing feeling unusually hot to the touch can indicate high friction due to bearing wear.
Reduced Performance: A drop in hydraulic pressure or slow operation can be a symptom of a failing pump and its bearings.
Metal Shavings in Oil: The presence of metal particles or shavings in the hydraulic oil is a clear sign of internal wear, including the bearings.
