Hydraulic System Troubleshooting, Testing and
Adjustment
ARM OPERATING CIRCUIT
The arm operating circuit includes both the right and left hydraulic main pumps, the right and left halves of
the control valve, arm regeneration valve, and the arm cylinder. The circuit can be operated in the two-
stage speed control mode which works through both halves of the control valve and doubles the volume of
oil flowing to the cylinder.
Overload relief valves set at 360 kg/cm
2
(5,112 psi) have been installed at the crowd and dump cylinder
ports on ARM1 side of the control valve to protect the circuit and system components from possible
damage caused by shocks and/or overload pressure. Additional protection - to prevent cavitation of the
cylinder - is provided by a make-up valve and reservoir return circuit, which ensures that the volume of oil
going to the cylinder will not exceed the volume of oil coming out.
ARM CROWD CIRCUIT
When the arm control lever is put in the crowd
mode, the left side pilot valve generates
secondary pressure that is transmitted to the
ARM1 and ARM2 of the control valve
simultaneously.
When secondary pilot pressure reaches 7 - 10
kg/cm
2
(100 - 142 psi), the arm control valve
spools ARM1 and ARM2 open. Output flow from
both pumps is directed to the arm cylinder.
When working in the arm crowd mode, under
certain conditions, oil in the arm cylinder could
suddenly be forced out by the weight of the arm
and bucket. Insufficient oil flow to the cylinder
could lead to cavitation in the cylinder head and/
or surging or irregular movement. This is
prevented by a regeneration valve attached to
the control valve which maintains the balance
between oil flowing into the cylinder and oil
flowing out.
ARM DUMP CIRCUIT
When the arm control lever is put in "dump"
mode, the left side pilot valve generates
secondary pilot pressure that goes to both
spools ARM1 and ARM2 of the control valve
simultaneously.
When pilot pressure reaches 7 - 10 kg/cm
2
(100
- 142 psi), the control spools open, allowing oil
from PUMP(L) and PUMP(R) to flow to the arm
cylinder.
