Switch Kit Hydraulic Circuit Diagram (rear attachment selected)
A hydraulics switch kit (model 08783) is available for Sand Pro 5040 machines
to support the hydraulic needs of various front and 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 mounted to the machine frame near the kit hydraulic pump and
includes three 2 position solenoid valves and a relief valve.
When the switch kit PTO switch is in the O
are de-energized so hydraulic fluid can pass through the manifold and back
to the hydraulic tank.
When rear remote hydraulics is selected and the switch kit PTO switch is in
the O position, solenoid valves SV1 and SV3 are energized and fluid flow is
N
directed to the rear female quick disconnect fitting. When front remote hydraulics
is selected and the switch kit PTO switch is in the O
SV1 and SV2 are energized and fluid flow is directed to the front female quick
disconnect fitting. The the front and rear attachment circuit pressure is limited to
17,233 kPa (2500 psi) by the relief valve in the kit manifold.
