HYDRAULIC SYSTEM - CONTINUED
Connected through high pressure oil lines to jaw direct linear valve.
Opens and closes backhoe bucket jaw.
BACKHOE CONTROL VALVE
Fed by high pressure oil line from pressure control valve via jaw direct linear valve.
Returns low pressure hydraulic fluid through oil lines via jaw direct linear valve to hydraulic oil filter relief valve.
Bank of six separate valves bolted together uses common hydraulic fluid supply and return oil lines.
Closed center design. Hydraulic fluid flows through valve only when operated out of neutral by moving backhoe
control valve levers.
Controls operation of backhoe boom, swing, bucket, crowd, and stabilizer cylinders through high pressure oil lines.
BACKHOE CONTROL VALVE-TO-JAW DIRECT LINEAR VALVE OIL LINE
Routes low pressure hydraulic fluid from backhoe control valve, to jaw direct linear valve-to-hydraulic oil filter relief
valve oil line.
