Hydraulic system _________________________________________________ Major hydraulic components (Reference Fig. 28) return filter
The return filter is located on the left hand side of the machine near the primary operator’s station. This filter is used to filter fluid on the return side of the hydraulic circuit and as the power fill filter.
pressure filter
The pressure filter is located on the left hand side of the machine near the operator’s station. This filter is used to filter fluid on the pressure side of the hydraulic circuit.
piggyback gear pump
The piggyback gear pump is bolted to the rear of the open loop load sense pump. This pump supplies hydraulic fluid to the main pump and the conveyor motor for cooling purposes and also supplies fluid to the fan hydraulic motor on the heat exchanger.
open loop load sense pump
The open loop load sense pump is a part of the breaker power unit and is located on the right side of the machine. It supplies hydraulic fluid to all hydraulic functions on the machine.
frame lift cylinders
The frame lift hydraulic cylinders are located at the pivot point of the crawler on each side of the machine and are used to adjust the ground clearance of the machine. Each cylinder is individually controlled by separate sections of the valve bank.
frame tilt cylinders
The frame tilt hydraulic cylinders are located at the end of the crawler under the hopper on each side of the machine and are used to adjust the discharge height of the machine. The cylinders are controlled by one section of the primary valve bank.
conveyor motor
The conveyor motor is located on the left hand side of the machine, and is mounted directly to the conveyor reducer. This radial piston motor receives hydraulic fluid from the main valve bank’s first and second sections.
valve bank
The valve bank, located on the left hand side of the machine directly above the crawler, is used to control the machine’s conveyor, tilt, lift, tram, and power fill functions. All sections of the valve bank are spring return (self centering) except for the power fill section which is detented. WARNING! The tilt and lift hydraulic cylinders have counterbalance cartridges which serve as load holding valves. Do not replace these cylinders with different style cylinders or the machine may fall. The machine could be damaged or you or other personnel could be seriously injured or killed by the falling machine.
