Rear Remote Hydraulic Circuit Diagram
A remote rear hydraulics kit (model 08781) is available for both Sand Pro 3040
and 5040 machines to support the hydraulic needs of various rear attachments.
The kit includes its own fixed displacement gear type hydraulic pump (P3) and
a separate hydraulic manifold. The pump is driven by the engine directly, and
mounted to the rear of the engine through a rubber isolated bracket. The valve
manifold is located on the left side of the machine below the hydraulic tank and
includes a solenoid operated relief valve.
When the remote rear hydraulics PTO switch is in the O
allows hydraulic fluid to pass through the manifold, out port 2, and back to the
hydraulic tank. A kPa (65 psi) check valve in the attachment supply line helps
prevent the attachment from rotating while disengaged. When the remote rear
hydraulics PTO switch is set to the O
fluid flow is directed to the rear female quick disconnect fitting. The attachment
circuit pressure is limited to 17,233 kPa (2500 psi) by the solenoid operated
relief valve.
