(5) Hydraulic tank | |
The hydraulic tank (5) provides oil for all hydraulic systems on the machine. The hydraulic tank is located behind the operator platform.
 | |
| Illustration 4 | g00706540 |
(4) Gear pump | |
The gear pump (4) draws oil through the strainer in the hydraulic tank (5). The gear pump is driven by the accessory drive group on the engine. The pump is located on the right side of the engine.

(2) Steering cylinder | |
When the steering wheel is turned, the metering pump (1) sends oil to one end of each steering cylinder (2). The steering cylinders articulate the machine.

| Illustration 7 | g00706651 |
(3) Blade control valve | |
The gear pump supplies hydraulic oil for the leveling blade circuit. Oil flows through the steering priority valve, that is located in the gear pump, to blade control valve (3). The control valve is located under the operator platform.

| Illustration 8 | g00706634 |
(6) Blade cylinder (7) Leveling blade | |
Control valve (3) directs oil to the blade cylinder and away from the blade cylinder (6). The blade (7) is raised and lowered by retracting or extending the cylinder.
