TUBE AS 3472305 - Caterpillar

5. Slowly close the manual load valve (on flow meter) to set system pressure at 5500 kPa (800 psi).6. Observe the flow meter. Record the pump output reading.7. Shut the engine off. Remove the flow meter and reconnect hoses (1) and (2) to relief manifold (3).8. Repeat steps 1 through 7 for the remaining vibratory control to measure output from the other section of the vibratory pump.9. Output from both sections of the pump should be about 76 liters/min (20 U.S. gpm). If output from either section is too low, see Troubleshooting for probable cause.Front Motor Flow Test

(1) High-amplitude pressure hose. (2) Low-amplitude pressure hose. (3) Front vibratory motor. (4) Case drain hose.1. Raise the entire machine on blocks so both drums can rotate without moving the machine.2. Disconnect low-amplitude pressure hose (2) from front vibratory motor.3. Connect the inlet of a flow meter to hose (2). Connect the outlet of the flow meter to motor (3).4. Open the manual load valve (on flow meter) fully.5. Start engine and run at
