If the lever feels 'heavy' when operated on your Doosan Excavators, it could be due to foreign material in the control valve spool, the valve spool sticking, or a lack of linkage lubrication. To address this, clean the control valve, replace the valve housing assembly, or lubricate the linkage.
Why is there an unusual sound from my Doosan DX35Z Excavators hydraulic pump?
An unusual sound from the hydraulic pump in Doosan Excavators can be attributed to several causes: cavitation from a bent suction side hose or clogged suction filter, cavitation from suction side fittings and air in the system due to low oil level, cavitation due to high viscosity oil, pump and engine misalignment, or air in the hydraulic oil. Suggested solutions include replacing the hose and filter, tightening fittings and adding oil, replacing the oil, readjusting the shaft, or bleeding the system.
What causes oil leaks in Doosan Excavators?
Oil leaks in Doosan Excavators can stem from seals leaking or a worn O-ring, or parts sticking due to foreign material. The suggested solution is to replace worn or damaged parts and disassemble, check for damage, and clean the affected components.
Why is there a lack of cylinder power in my Doosan DX35Z Excavators?
A lack of cylinder power in Doosan Excavators can occur if the relief valve pressure is set too low, if there's an oil leak from inside the cylinder, if the cylinder piston or rod is damaged, or if there's an oil leak from inside the control valve. To resolve this, adjust the pressure, replace the cylinder seals, replace the piston or rod, or replace the valve housing assembly.
Why is there poor oil delivery in my Doosan DX35Z?
Poor oil delivery in Doosan Excavators can be attributed to a low hydraulic oil level or a restricted suction filter. To fix this, add oil or clean/replace the filter.
What causes a Doosan DX35Z Excavators hydraulic motor to not rotate?
A Doosan Excavators hydraulic motor might fail to rotate due to several reasons: low hydraulic oil, a bad hydraulic pump, an oil leak from inside the hydraulic motor, an overload applied to the output shaft, or low viscosity hydraulic oil. Possible solutions include adding oil, replacing the pump, replacing the motor, locating and removing the cause of the overload, or changing to oil with the correct viscosity.
What causes a Doosan DX35Z Excavators hydraulic motor to not allow turning to one side?
If a Doosan Excavators hydraulic motor will not allow turning to one side, it could be due to a bad control valve relief valve or a counterbalance valve spool sticking. To fix this, clean or replace the relief valve, or replace the counterbalance valve.
What causes Doosan Excavators to fail to bear load?
If Doosan Excavators fail to bear a load, it may be due to a leaky spool or a leaky port relief valve. To resolve this, replace the valve housing assembly relief valve or disassemble, clean, or replace the port.
How to troubleshoot a Doosan Excavators swing motion that drags while stopping?
If the swing motion drags while stopping on your Doosan Excavators, it could be due to a low port relief or brake valve pressure setting, or foreign material in the port relief or brake valves. To fix this, adjust the pressure or clean the valves.
How to fix spool sticking in Doosan DX35Z?
Spool sticking in Doosan Excavators can occur if the hydraulic oil is excessively hot due to blockage, if the hydraulic oil is fouled, or if the valve housing is deformed due to overtightened fittings on the hydraulic oil line. To resolve this, remove the blockage, change the oil and clean the oil passages, or replace the valve housing.
