Right Side of Machine
(1) Fill port
(2) Sight gauge

The hydraulic tank is in front of the engine and below the hydrostatic pumps. Access to the hydraulic tank is from the right side of the machine. The drum propulsion hydraulic system, the axle propulsion hydraulic system, the vibratory hydraulic system, the steering hydraulic system, and the fan hydraulic system share a common hydraulic tank.

The hydraulic tank is nonpressurized. Fill port (1) is located on the right side of the hydraulic tank. A cover plate provides access to the fill port. The cover plate is not shown.

Sight gauge (2), that is on the right side of the hydraulic tank, indicates the oil level in the hydraulic tank with two sight glasses. The sight glasses are visible when the cover plate is installed. Oil should always cover the bottom sight gauge. The oil level should be visible in the upper sight glass, but not over the center of the glass. The capacity of the hydraulic tank is 90 L (23 US gal).

Note: If the hydraulic oil and the filters are changed at the same time, 96 L (25 US gal) is needed to refill the system.

Rear of Hydraulic Tank
(3) Hydraulic oil temperature switch

Hydraulic oil temperature switch (3) is mounted to the rear side of the hydraulic tank. Contact "B" of this switch is connected to terminal "J1-44" of the engine ECM. Contact "C" of this switch is connected to the common return line at terminal "J1-35" of the engine ECM.

The engine ECM monitors the circuit at terminal "J1-44". When the hydraulic oil temperature is less than the actuation temperature of the switch, the switch is open. In this case, the engine ECM reads an open circuit at terminal "J1-44". When the hydraulic oil temperature is greater than the actuation temperature of the switch, the switch opens. When the switch is open, the engine ECM reads an open circuit at terminal "J1-44". In this case, the engine ECM illuminates the hydraulic temperature indicator on the instrument panel.
