FROM WORK EQUIPMENT
CYLINDER
★
Oil temperature for measurement: 45 ~ 55°C
★
If the hydraulic drift exceeds the standard value,
measure the leakage in the cylinder to see if the
cause of the hydraulic drift is on the control
valve side.
•
If the leakage is below the standard value, the
cause of hydraulic drift is on the control valve
side.
•
If the leakage is above the standard value, the
cause of hydraulic drift is on the cylinder side.
1. Fully extract the rod of the cylinder to be
checked and stop the engine.
2. Disconnect the hose from the cylinder head and
plug it.
• Boom cylinder: Hose (1)
• Arm cylinder: Hose (2)
• Bucket cylinder: Hose (3)
• Offset cylinder: Hose (4)
