What to do if there is no hydraulic oil flow in Manitowoc Grove GRT9165?

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.

Excessive pressure buildup in your Manitowoc Construction Equipment can be caused by a system relief valve set too high; adjust it using an adequate pressure gauge as necessary. Alternatively, there might be a restricted pump-to-control valve supply line; clean, repair, or replace the line as needed.

What to do if a specific hydraulic system (lift, hoist, telescope, swing) is not working on my Manitowoc Grove GRT9165 Construction Equipment?

If a specific hydraulic system isn't working on your Manitowoc Construction Equipment, begin by checking the system for leaks, making repairs as needed, and refilling the reservoir. The issue might also stem from a faulty hydraulic remote control valve (adjust or replace it), a faulty directional control valve (replace it), a poorly adjusted control in the circuit (troubleshoot the circuit with a schematic and adjust the hydraulic component per the schematic), or a faulty hydraulic cylinder, motor, or valve (replace the faulty component).
