Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids. Refer to Special Publication, NENG2500, "Caterpillar Tools and Shop Products Guide" for tools and supplies suitable to collect and contain fluids on Caterpillar products. Dispose of all fluids according to local regulations and mandates. |

To avoid damage to the vibratory system during testing, always perform the testing with the vibratory drum on top of tires or on loose dirt. Tires will simulate a non-compacted soil condition. Never operate the vibratory system when the machine is on concrete. |
| NOTICE |
|---|
If a testing time longer than three (3) minutes is required, rotate the drum periodically in order to lubricate the eccentric weight shaft bearings. |
Note: The hydraulic oil temperature should be at least 38°C (100°F).
- Make sure that the parking brake is applied. Make sure that the propel control lever is in neutral. Make sure that the vibratory on/off control on the propel control lever is in the OFF position.
- Disconnect drain line (2) from vibratory motor (1) .

- Install 90 cm (36 inch)of 9X-2350 Hose and 4C-8689 Flow Meter (5) Between vibratory motor (1) and drain line (2) .
- Install 4C-6500 Digital Thermometer into the hydraulic oil tank.
- Move the vibratory amplitude control to the LOW AMPLITUDE position.
- Start the engine and run the machine at high idle until the hydraulic oil temperature reaches 38°C (100°F). Engine speed should be 2350 ± 50 rpm.
- When the vibratory system is off and when the machine is at high idle, read the amount of oil flow that passes through the flow meter. The flow should be less than 3.8 L/min (1 US gpm).
- Depress the vibratory on/off control to the ON position in order to start the vibratory system. The flow should be at a minimum of 5.0 L/min (1.3 US gpm) to a maximum 8.8 L/min (2.3 US gpm).
- Depress the vibratory on/off control to the OFF position in order to stop the vibration system. Stop the engine.
- Move the vibratory amplitude control to the HIGH AMPLITUDE position.
- Repeat Steps 7 through 9.
- If the flow is not within 5.0 L/min (1.3 US gpm) to a maximum8.8 L/min (2.3 US gpm), the size of the orifice in the flushing valve may need to be changed. The diameter of the orifice should be 1.9 mm (0.075 inch). If the flow from the vibratory motor cannot be adjusted correctly, the vibratory motor should be repaired or replaced.
- Remove all test tooling and reconnect line (2) to motor (1) .
