P/N 3031863-001 (PV3-240-10D) Engine Driven Pump Approved For Installation on Airbus A300/A310/A320 Series; Boeing B757/B767/B747, DC-10/MD-10/MD-11 Lockheed L1011 Extensive analysis and verification testing has resulted in the development of a substantial product improvement to Eaton's Vickers® P/N 887673 hydraulic pump (PV3-240-10C). This modification will significantly reduce external leakage associated with the face seal at the parting line interface between the adapter block and housing. The product improvement to the P/N 887673 (PV3-240-10C), introduced as P/N 3031863001...

Flow Schematic Approved For Installation on Airbus A300/A310/A320 Series; Boeing B757/B767/B747, DC-10/MD-10/MD-11 Lockheed L1011 Design Features Seals The cross-section in Figure 1 illustrates the seal design of P/N 3031863-001 (PV3-240-10D). The product improvements eliminate the face seal and introduces radial seals to prevent leakage from the pump control to the external environment. The improvement also eliminates the plug and plug seal, which has also had reported leakage issues, refer to the cross-section on page 3. The improvements to the control pressure pulsation levels and the...

Pulsation Levels Approved For Installation on Airbus A300/A310/A320 Series; Boeing B757/B767/B747 DC-10/MD-10/MD-11 , Lockheed L1011 As mentioned in the design feature section, the timing change to the wafer plate reduces the yoke moment oscillation. The predicted reduction in yoke moment variation was 29%-50%, see Figure 2 below. Figure 2. Comparison of Predicted Yoke Moment Oscillation for 887673 Mod L and 3031863-001 Configurations versus Pump Speed The new design features of the 3031863-001 have been tested with very favorable results. The control pressure pulsations were reduced...
