The vibratory system consists of the following components: vibratory pump (1), oil filter (4), vibratory motor (6), hydraulic oil tank (12), hydraulic oil cooler (13) and bypass valve (14) .
The charge oil for the vibratory system is supplied by the charge pump (7). Charge pump (7) is a gerotor type pump that is integral to the vibratory pump (1) .
Two vibratory systems are available:
- The dual amplitude system is a standard for the machine.
- The variable frequency system is an option for the machine.
The adjustment of the pump swashplate angle is the only change between the two vibratory systems.
Note: The throttle switch has two sets of contacts. The throttle switch must be in the high position for the vibration to work.

Right Side Of Engine (1) Vibratory pump. | |
Vibratory pump (1) is a variable displacement axial piston design. The vibratory pump is mounted in-line with the two propel pumps. The three pumps are driven by the engine in a clockwise direction.
Note: The CS-531D does not have a drum propel pump.

Right Side Area Of Drum (6) Vibratory motor. (15) Drum support bearing housing. | |
Vibratory motor (6) is located on the right side of the drum, mounted to a drum support housing (15). Vibratory motor (6) is a fixed displacement axial piston motor. The flushing valve is built in the motor. A change in the direction of the oil flow to the vibratory motor changes the direction of the vibratory shaft. The change of direction in the vibratory shaft will change the vibratory amplitude.

Left Side Of Machine (4) Oil filter. (16) Pressure switch. | |
Oil filter (4) is dedicated to the vibratory circuit. Oil from the charge pump flows through the oil filter before entering the vibratory circuit.
The pressure switch (16) will activate the alarm and the indicator light when the pressure is below 1200 kPa (174 psi). The indicator light is located on the steering console.
