Left Rear Wall Inside Cab
(1) Back-up alarm relayBack-up alarm relay (1) is located in the fuse and relay bank. The panel in the left rear wall of the cab (shown removed) provides access to this component.Back-up alarm relay (1) controls the power supply to the back-up alarm. When this relay is energized, the back-up alarm sounds. The machine ECM controls the signal to the coil of the back-up alarm relay. The machine ECM energizes this relay when the propel lever is in the reverse range.

Under Operator Platform on Left Side of Machine
(3) Shift solenoidShift solenoid (3) is located on the left side of the machine, under the operator platform. The shift solenoid is part of the shift manifold.Shift solenoid (3) controls the oil flow used to shift the propel motors. When the shift solenoid is not energized, the propel motors operate in the low-speed range. When the shift solenoid is energized, the propel motors operate in the high-speed range.When the propel mode is set to high, the machine ECM generates a digital signal in order to energize shift solenoid (3).The shift manifold contains three ports. The ports are labeled for identification. Charge oil is directed from port "PS" of the vibratory pump to port "P" of the shift manifold. Port "C" of the manifold is connected to the shift inlet passage of the axle motor and the drum motor. Port "T" of the shift manifold is connected to the hydraulic tank.
