Illustration 2 g00927698
Hydraulic tank (1) supplies oil to the steering, fan, and leveling blade system by providing oil for the gear pump (charge and steering). The hydraulic tank is located on the right side of the compactor below the operator platform.Gear Pump (Charge and Steering)
Illustration 3 g00927823
Gear pump (2) is located on the machine, as shown.The gear pump provides charge oil for the following components:
Gear motor (fan)
Steering system (valve, metering pump, and hydraulic cylinders)
Leveling blade system (valve and cylinder)Metering Pump (Steering)
Illustration 4 g00927824
Metering pump (3) is located on the machine, as shown. This component delivers oil to the steering cylinders. The metering pump consists of a control section and a gerotor pump. The metering pump (gerotor) controls the rate of oil flow through the control section and to the steering cylinders. The control section controls the direction of the oil. The oil will then go to the hydraulic cylinders.Hydraulic Cylinders (Steering)

Hydraulic cylinders (4) for the steering system are located on the machine, as shown. The steering system contains two hydraulic cylinders.Gear Motor (Fan for Hydraulic Oil Cooler)
Illustration 6 g00927837
Gear motor (5) is located on the machine, as shown. This gear motor turns the fan for the hydraulic oil cooler. The oil flow for this gear motor is supplied by the gear pump (steering and charge).Hydraulic Oil Cooler
Illustration 7 g00927838
Hydraulic oil cooler (6) is located on the machine, as shown. The hydraulic oil cooler maintains the hydraulic oil at the correct operating temperature.Control Valve (Blade)
Illustration 8 g00927841
Control valve (7) is located on the machine, as shown. Oil is supplied to the control valve by the gear pump (charge and steering).This control valve controls the following positions for the leveling blade:
