The hydraulic tank (torque converter, hoist, brake, and transmission) has two separate oil tanks. The torque converter, hoist, and brake section (1) is separated from the transmission section (2) by a wall inside the hydraulic tank. The transmission section (2) is smaller than the torque converter, hoist, and brake section (1) and provides oil for the transmission. The torque converter, hoist, and brake section (1) is larger than the transmission section (2) and provides oil for torque converter operation, hoist operation, and brake operation and cooling. The hydraulic tank is mounted to the left side of the frame.
A relief valve for rear brake cooling (4) is located inside the torque converter, hoist, and brake section (1). The relief valve for rear brake cooling (4) provides hydraulic pressure relief to the rear brake coolers. Torque converter, hoist, and brake section (1) also contains control valve (3) for the hoist cylinders.
Both transmission section (2) and torque converter, hoist, and brake section (1) are vented to breathers. Breathers for the torque converter, hoist, and brake section (1), the oil pump drive, and the torque converter are located on the right side of the horizontal frame member above the torque converter. The transmission breather is located on top of transmission section (2).
