Why is the hydraulic pump noisy and the pipeline vibratory in SUNWARD SWE20B Excavators?
- AAaron TaylorAug 2, 2025
The noisy hydraulic pump and vibratory pipeline in your SUNWARD Excavator can be attributed to several reasons: * Hydraulic malfunction: It is recommended to consult with your dealer. * Air bubble in the hydraulic system: Check for air leakage at the oil pump inlet pipeline. * Aging hydraulic oil: The oil might be degenerative, mixed with moisture, or of the wrong brand and specification, causing bubbles. Replace the oil. * Low hydraulic oil temperature: High oil viscosity can be a factor. Run the engine at low revolutions per minute (RPMs) to warm it up.
