TM 5-3805-262-343-15. AUXILIARY STEERING PUMP AND MOTOR MAINTENANCE (CONT)a. FlowmeterTest(SHEET5OF5).(18) Record tester AMMETER reading.(19) Open flowmeter PRESSURE VALVE completely and set ignition key switch toOFF position.(20) If auxiliary steering pump flow recorded in step (17) above is 6.4 gal-lons per minute and tester AMMETER reading recorded in step (18) above is525 amperes or less, auxiliary steering pump and motor are okay. If flowis less than 6.4 gallons per minute or amperage is more than 525 amperes,remove and replace auxiliary steering pump and motor (page 3-531).(21) Disconnect load leads and ammeter clamp of starter and charging systemtester from battery posts and cable.(22) Open access door in front of loader.(23) Loosen hydraulic reservoir fill cap (1) to relieve air pressure in hy-draulic reservoir. Tighten hydraulic reservoir fill cap (1) after airpressure has been relieved.(24) Disconnect flowmeter inlet hose (4) from hose (2) and flowmeter (7).(25) Disconnect flowmeter outlet hose (6) from fitting (3) and flowmeter (7).(26) Connect and tighten hose (2) fitting to fitting (3).(27) Start engine and operate at idle speed for two minutes then increaseengine speed to full throttle for two minutes.(28) Pull out fuel SHUT OFF control to stop engine but keep ignition keyswitch in RUN position.(29) Check that auxiliary steering pump and motor is operating; if it is notoperating, go to troubleshooting (page 2-117).Before performing following step, warn personnel to stay away from sidesof loader between front and rear chassis. Failure to do so will causedeath or serious injury to those personnel due to chassis pivoting andcrushing them. If personnel are injured, obtain medical assistanceimmediately.(30) Wait one minute then turn steering wheel all the way to the right thenall the way to the left to bleed air from system.(31) Set ignition key switch to OFF position.(32) Check for oil leakage at auxiliary steering pump and motor. Tightenfittings as necessary.3-530
