  If no hydraulic oil flows in your Manitowoc Construction Equipment, first check the hydraulic oil level, looking for leaks and repairing them as needed, then refill the reservoir. Also, inspect the reservoir-to-pump suction lines for damage or restrictions, ensuring they are secure and properly attached. If the pump shaft is damaged, repair or replace it. Finally, check for internal contamination; if found, drain and flush the system with the recommended oil mixture before refilling with the recommended hydraulic oil.

Why is my Manitowoc Grove GRT9165 responding slowly?

  Gary RiveraAug 12, 2025
  A slow response in your Manitowoc Construction Equipment could be due to several factors. First, check the hydraulic oil level for leaks and refill the reservoir if needed. Also, the hydraulic oil temperature may be too high (making the oil too thin) or too low (making the oil too thick). If the temperature is too low, warm up the system; if too high, troubleshoot the cooler circuit, paying attention to the in-line check valve and related hydraulic circuits. Lastly, a faulty pump could be the cause, so consider repairing or replacing it.

  If the pump in your Manitowoc Construction Equipment is noisy and the hydraulic oil is foaming, start by checking the hydraulic oil level for leaks and refill the reservoir if necessary. Excessive engine speed can also cause this issue, so regulate the engine speed. Additionally, check all suction lines for security and proper repair, tightening, repairing, or replacing parts as needed to prevent air from entering.
