ASSembly.(1) Position body (31), and install needle bearing (30), check valve (29), plate and seal assembly (28)and drive shaft and gear assembly (27).(2) Install idler gear (26), new O-ring (25), needle bearing (24), cover (23), dowel pin (22) and screws(21).(3) Install seal plate (20) and screws (19).(4) Install flange eyelet (18), spring (17), valve plug (16), new o-ring (15), pressure valve block (14),sealing washer (13), flat washer (12), pressure setscrew (11 ) and locknut (1 O).(5) Install adapter (9), woodruff key (8), drive gear (7), castellated nut (6) and cotter pin (5).e. Testing.(1) Install hydraulic pump assembly on a suitable test stand and provide a means of rotating atapproximately 600 RPM.(2) Connect a hydraulic line to pump assembly inlet.(3) Connect a hydraulic line equipped with a pressure gauge, and a restriction valve to the pumpassembly outlet.(4) Operate pump at approximately 600 RPM.(5) Close restriction valve until pressure gauge reads 320 +10 PSI. If 320 ± 10 PSI is not obtainable,loosen locknut and adjust pressure relief valve screw until 320 ± 10 PSI is reached.(6) Slowly close the restriction valve while observing the pressure gauge. The pressure should drop. Ifnot, continue to adjust pressure relief valve screw until pressure does drop.(7) Loosen locknut and adjust pressure setscrew (11, figure 3-34) until pressure gauge indicates 320± 10 psig.3-84
