Attachment Circuit
g262196
Attachment Circuit Diagram (engaged)
The machine includes a single function hydraulic circuit to support the hydraulic
demands of a rear mount attachment. Gear pump (P3), a 5-position auxiliary
load valve located between the operator and passenger seats, and a pair of
hydraulic lines with quick disconnect fittings are part of the standard attachment
circuit. The attachment circuit can be expanded to include an additional hydraulic
function by installing a selector control valve kit (optional); refer to
Control Valve (SCV) Circuit (optional) (page 5–33)
for additional information.
The gear pump section closest to the piston pump, gear pump section (P3),
supplies fluid to the attachment circuit. Hydraulic fluid from gear pump (P3)
enters the auxiliary load valve and is directed as follows based on the auxiliary
load valve position:
•
When the auxiliary load valve is in the A (
DETENT
) or the A (
MANUAL
) positions,
flow is directed to supply line A. Return flow from supply line B is allowed to
return to the hydraulic tank.
•
When the auxiliary load valve is in the NEUTRAL/HOLD position, flow
bypasses the attachment supply lines A and B. The flow either returns to
the hydraulic tank or is made available to supply the hydraulic demands of
the optional loader. Return flow from both attachment supply lines A and
B is blocked.
•
When the auxiliary load valve is in the B position, flow is directed to
attachment supply line B. Return flow from supply line A is allowed to return
to the hydraulic tank.
•
When the auxiliary load valve is in the FLOAT position, flow bypasses the
attachment supply lines A and B. The flow either returns to the hydraulic tank
or is made available to supply the hydraulic demands of the optional loader.
Attachment supply line flow is allowed to move in either direction with little
to no pressure.
The hydraulic load for the attachment circuit is limited to 20,684 kPa (3000 psi)
by a relief valve in the auxiliary load valve.
