Hydraulic System Troubleshooting, Testing and

Adjustment

OPERATION OF WORKING COMPONENTS

BOOM OPERATING CIRCUIT

The boom operating circuit includes the right and left main hydraulic pumps (both halves of the main pump
assembly), both sides of the control valve and the boom cylinder. The circuit operates in boom down mode
through the first shift position and through the second shift position in boom up mode. Overload relief

valves set at 360 kg/cm

2

 (5,112 psi) protect the hydraulic system from damage as a result of overloads or

shocks to the boom.

BOOM UP CIRCUIT

When you pull the boom control lever backward,
the right side pilot valve generates secondary
boom up pilot pressure that is transmitted to the
right and left sides of the control valve
simultaneously. When secondary pilot pressure

reaches 7 - 9 kg/cm

2

 

(101- 130 psi), boom

control valve spools open and oil from both
pumps goes to the boom cylinder.

BOOM DOWN CIRCUIT

When the boom control lever is pushed forward,
the right side pilot valve generates secondary
boom down pilot pressure that is transmitted
only to the left side of the control valve. When

secondary pilot pressure reaches 7 - 9 kg/cm

2

(101 - 130 psi), the valve spool on the left side
of the control valve opens so that oil from only
one half of the pump assembly goes to the
boom cylinder for boom lowering.
