FLANGE 3N8415 - Caterpillar

Test Procedure
Note: The steps in the procedure correlate with the steps under the "Test Specifications" according to your specific part number.The contamination level of the hydraulic oil in the test bench should be ISO 16/13 or better. The oil in the test bench should be one of the following.
SAE 10W at 50 °C (122 °F) or
Mobil DTE-11 at 46 °C (115 °F)

Pump characteristics
(P) Discharge pressure
(Q) Discharge flowNote: For Steps 1, 2, 5, and 6 be sure Adjustment knob for discharge flow (57) and Adjustment for the discharge pressure (60) are completely backed out on the 4C-3582 Load Sensing Valve.
Start rotating the pump according to the RPM in Step 1 of the"Test Specifications". Listen for abnormal noise. Verify flow from the pump. Verify that all connections are tight. Check for leaks around shaft seals. Check for leaks around the control valve.Run the pump for at least 5 minutes to raise the temperature of the oil and purge the system of air.
Slowly increase the input RPM to the value in Step 2 of the"Test Specifications". Record the discharge flow. If the actual flow is less than the value in Step 2 of the "Test Specifications", the pump may not be mechanically feasible.
