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, a slow return orifice, 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

AM 1

and

AMD 1

ports on

the right 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
AM1 and AM2 spools of the control valve
simultaneously.

When secondary pilot pressure reaches 7 - 9

kg/cm

2

(100 - 130 psi), the arm control valve

spools AM1 and AM2 open. Output flow from
both halves of the pump assembly 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 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 AM1 and AM2 of the control valve
simultaneously.

When pilot pressure reaches 7 - 9 kg/cm

2

(100 -

130 psi), the control spools open, allowing oil
from PUMP (L) and PUMP (R) to flow to the arm
cylinder.
