Why are all operating speeds slow and power is lost on my Kobelco SK55SRX-6?

Mr. Brandon OneillAug 14, 2025
The slow operating speeds and power loss in your Kobelco Excavators may be due to several reasons. Check if the hydraulic oil level is low and fill it to the specified level. Air leaking into the suction pipe could also be a cause; try tightening the suction pipe hose clamp or replacing the hose. Other potential issues include a damaged hydraulic pump or pilot gear pump, which would require repair or replacement. Finally, the main or pilot relief valve might not be adjusted correctly, requiring adjustment or replacement.

Suzanne HarrellAug 18, 2025
If your Kobelco Excavators machine does not slew, it could be due to several issues. The hydraulic motor (slewing) might not be working, or the slewing gear could be damaged, requiring repair or replacement. Other potential causes include a damaged slewing bearing, a malfunctioning pilot valve, or a damaged slewing reduction unit, all of which would need repair or replacement. Additionally, check if the solenoid valve, control valve, or lever lock solenoid valve are not working, and repair or replace as necessary.

What to do if my Kobelco SK55SRX-6 Excavators traveling power is insufficient?

Duane ShawAug 21, 2025
Insufficient traveling power in your Kobelco Excavators may stem from several issues. A damaged hydraulic pump or poor engine performance could be the cause, both requiring repair or replacement. Also, check if the main relief valve pressure is set incorrectly and adjust it as needed. Other potential factors include a low hydraulic oil level (fill to proper level), a malfunctioning hydraulic motor (travel), or a faulty brake valve, all necessitating repair or replacement. Finally, a scored seal in the swivel joint or oil leakage could also contribute to this problem; repair or replace the affected components.

Why does my Kobelco SK55SRX-6 machine not travel smoothly?
C
Chad RiveraAug 25, 2025
If your Kobelco Excavators machine does not travel smoothly, there are several potential causes. It could be due to too much crawler tension (adjust crawler tension), dirty or clogged crawler belts/shoes (clean crawlers), or a malfunctioning brake valve (repair or replace). Other possible issues include a damaged travel reduction unit, a faulty control valve, or a damaged travel motor, all requiring repair or replacement. Additionally, an incorrectly set main relief valve pressure (adjust or replace) or a damaged swivel joint (repair or replace) could also be contributing factors.

What to do if a specific cylinder functions improperly or loses power on my Kobelco SK55SRX-6?
K
Kimberly MunozAug 30, 2025
If a specific cylinder on your Kobelco Excavators functions improperly or loses power, it could be due to a damaged cylinder seal, which would need repair or replacement. Another cause might be an incorrectly functioning control valve or overload relief valve, or signs of air in the cylinder; repair or replace the valve, and remove air from the cylinder. A damaged pilot valve or loose pilot valve piping could also be responsible; repair or replace the valve, and retighten the piping.

Why doesn't my Kobelco SK55SRX-6 machine travel in a straight line?
A
Adrian RandolphSep 3, 2025
If your Kobelco Excavators machine does not travel in a straight line, it could be due to several factors:
* Unequal tensions on crawlers (adjust tension).
* Unbalanced set pressures of main relief valves (adjust).
* Deteriorated performance of the hydraulic travel motor (repair or replace).
Other potential causes include unbalanced flow from the control valve, hydraulic pump, brake valve, or RH swivel joints, all requiring repair or replacement.

What causes abnormal sound when slewing Kobelco Excavators?
D
Dustin WilliamsonSep 7, 2025
An abnormal sound during slewing in your Kobelco Excavators could be due to insufficient lubrication of the slewing gear and bearings (grease). Alternatively, a malfunctioning pilot valve or control valve may be the cause, requiring repair or replacement.

What to do if the cylinder position will not hold with operating lever in neutral on Kobelco Excavators?
C
Christine MiddletonSep 10, 2025
If the cylinder position on your Kobelco Excavators will not hold with the operating lever in neutral, it could be due to a scored cylinder seal, a damaged control valve or overload relief valve, or a damaged pilot valve. In each case, repair or replacement of the affected component is necessary.
