ROTOR-SENSOR 3792196 - Caterpillar

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).High Amplitude
Make sure that the parking brake is applied. Ensure that the propel control lever is in the STOP position.

Connect a 60000 kPa (8700 psi) pressure gauge to relief valve test port (1) .

Control Console (2) Vibratory amplitude control. (3) Vibratory ON/OFF control.
Move amplitude selector (2) to the HIGH AMPLITUDE position.
Install the Multitach in order to measure engine rpm. Install 4C-6500 Digital Thermometer into the hydraulic oil tank. Start the machine and run the machine at high idle (2390 25 RPM) until the hydraulic oil temperature reaches 38°C (100°F).
Look at the gauge and depress vibratory control switch (3) to the ON position in order to start the vibratory system.Note: The force that is needed to overcome the inertia of the weights causes the pressure in the vibration system to momentarily reach the high amplitude relief valve setting. Look at the gauge and turn on the vibration system. The highest reading on the gauge is the high amplitude relief valve setting.
The high amplitude relief valve setting should be 29000 kPa to 33100 kPa (4200 psi to 4800 psi).

If the high amplitude relief valve setting is not correct, high amplitude relief valve (4) must be replaced.
When the new relief valve for the high amplitude is installed, check the pressure setting again. Once the setting for the relief valve is correct, stop the engine and remove all the tooling.Note: If continued high pressure is observed, a problem may exist with the vibratory drive mechanism.Low Amplitude
Make sure that the parking brake is applied. Ensure that the propel control lever is in the STOP position.

Vibratory Flushing Manifold (1) Test port for low amplitude
Connect a 60000 kPa (8700 psi) pressure gauge to relief valve test port (1) .

Move amplitude selector (2) to the LOW AMPLITUDE position.
Install the Multitach in order to measure engine rpm. Install 4C-6500 Digital Thermometer into the hydraulic oil tank. Start the machine and run the machine at high idle (2390 25 RPM) until the hydraulic oil temperature reaches 38°C (100°F).
Look at the gauge and depress vibratory control switch (3) to the ON position in order to start the vibratory system.Note: The force that is needed to overcome the inertia of the weights causes the pressure in the vibration system to momentarily reach the low amplitude relief valve setting. Look at the gauge and turn on the vibration system. The highest reading on the gauge is the low amplitude relief valve setting.
The low amplitude relief valve setting should be 29000 kPa to 33100 kPa (4200 psi to 4800 psi).
