| Pump 1 Flow Rate Control Valve | Pump 2 Flow Rate Control Valve | Flow Combiner Valve Control Spool |
| Supplies flow rate control pressure Pi to pump 1 regulator in response to lever stroke when boom (raise/lower), arm (roll-out/in), bucket (roll-out/in), right travel or auxiliary is operated. | Supplies flow rate control pressure Pi to pump 2 regulator in response to lever stroke when boom (raise/lower), arm (roll-out/in), swing (right/left), left travel or auxiliary is operated. | Be shifted by right travel pilot pressure and supplies control pressure to flow combiner valve in control valve. |
| If spool is bound at fully open, even if control lever is in neutral, pump 1 swash angle is tilted to maximum. (When traveling with travel levers held in half stroke, machine mistracks to the left.) If spool is bound at fully open, pump 1 control pressure sensor monitors the maximum pressure. If spool is bound at fully closed, even if control lever is operated, pump 1 swash angle is tilted to minimum. (Right travel is inoperable during single travel operation. Bucket speed becomes very slow.) If spool is bound at fully open, pump 1 control pressure sensor cannot monitor the pump control pressure. (Right travel does not run fast with right track jacked-up.) |
If spool is bound at fully open, even if control lever is in neutral, pump 2 swash angle is tilted to maximum. (When traveling with travel levers held in half stroke, machine mistracks to the right.) If spool is bound at fully open, pump 2 control pressure sensor monitors the maximum pressure. If spool is bound at fully closed, even if control lever is operated, pump 2 swash angle is tilted to minimum. (Left travel is inoperable during single travel operation. Swing speed becomes very slow.) If spool is bound at fully open, pump 2 control pressure sensor cannot monitor the pump control pressure. (Left travel does not run fast with left track jacked-up.) |
If spool is bound at fully open, when boom, arm, bucket or swing is operated, flow combiner valve is shifted. If spool is bound at fully closed, when combined operation of travel and front/swing is made, machine mistracks to the left. (Left travel speed becomes slow.) |
