Pump flow should be approximately as follows: 117 mL (7.14 cu.in.) per stroke at 1720 kPa (250 psi) maximum4.2 mL (.257 cu.in.) per stroke at pressure more than 1720 kPa (250 psi)2. Check operation of outlet check balls (50) and (53) by application of pressure to the outlet port with a different pump.3. If the pump is operating correctly and the shear seal valve is not, disassemble the valve. (See topic, DISASSEMBLY OF SHEAR SEAL VALVE ASSEMBLY, pages 10 and 11.)Disassembly Of Shear Seal Valve
