HYDRAULIC IMPACTOR VALVE

TM 5-2420-222-20-1

HYDRAULIC SYSTEM - CONTINUED

Fed high pressure hydraulic fluid through oil lines from pressure control valve.

Pedal operated valve controls flow of high pressure hydraulic fluid through flow regulator and oil line to hydraulic

impactor when installed.

HYDRAULIC IMPACTOR AND MOTOR ASSEMBLY (NOT SHOWN)

Attachment clamped between backhoe bucket jaw and backhoe bucket when installed.

High energy impact powered by high pressure hydraulic fluid through hydraulic impactor valve-to-impactor quick

coupler oil line.

HYDRAULIC IMPACTOR VALVE-TO-IMPACTOR QUICK COUPLER OIL LINE

Routes high pressure hydraulic fluid from hydraulic impactor valve-to-impactor quick coupler to operate hydraulic

impactor when installed.

HYDRAULIC IMPACTOR RETURN OIL LINE

Routes low pressure hydraulic fluid from hydraulic impactor, when installed, to backhoe control valve-to-jaw direct

linear valve oil line at backhoe control valve from return to hydraulic oil filter relief valve.

PRESSURE CONTROL VALVE-TO-LOADER CONTROL VALVE OIL LINE

Routes high pressure hydraulic fluid from pressure control valve to loader control valve.

LOADER CONTROL VALVE

Fed by high pressure oil line from pressure control valve.

Returns low pressure hydraulic fluid through oil line to hydraulic oil filter relief valve.

Bank of two separate valves bolted together use common hydraulic fluid supply and return lines.

Closed center design. Hydraulic fluid flows through valve only when operated out of neutral by moving loader

control valve handle and linkage.

Controls operation of loader boom and bucket cylinders through high pressure oil lines.

LOADER CONTROL VALVE-TO-HYDRAULIC OIL FILTER RELIEF VALVE OIL LINE

Routes low pressure hydraulic fluid from loader control valve-to-hydraulic oil filter relief valve.

LOADER CONTROL VALVE HANDLE AND LINKAGE

Handle with mechanical linkage attached to two valve spool devises.

Allows operator to control loader control valve boom and bucket valves to raise or lower, and retract or dump loader

bucket separately or at the same time.
