Hydraulic Manifold Block/Diverter Valve - Shibaura ST450 Operator's Manual

SECTION 2 – OPERATION
HYDRAULIC MANIFOLD BLOCK/DIVERTER
VALVE
The hydraulic manifold block/diverter valve is
located on the right-hand side of the tractor below
the platform. The manifold block distributes pump
oil to the HPL (Hydraulic Power Lift) valve,
2
optional rear remote valves, the transmission /
rear axle reservoir and the valve for attached
implement.

The diverter valve (1) in Figure 2-57, can be
turned with a blade screwdriver. In the 1 o'clock
1
position, hydraulic fluid is directed to the HPL
valve and rear remotes (optional). When a valve
4
for another attached implement is plumbed to the
three ports - (pressure out (2) in Figure 2-57,
Figure 2-57
pressure return (3) in Figure 2-57, and sump or
tank (4) in Figure 2-57), the diverter valve must
be turned counter-clockwise to 11 o'clock
position for hydraulic fluid flow to the implement
valve and then to the HPL valve and rear remote
valve (optional).
NOTE: The PTO valve and power steering
always receives hydraulic flow independent of the
manifold block diverter setting.
