TM 5-3805-262-34TEST NO. 2 - STEERING CIRCUIT AND RELIEF VALVE (SHEET 3 OF 5)g.Connect flowmeter (12) hoses (10 and 11) and adapters and assemble adaptersand nine inch return pipe (13) (p/o flowmeter fitting kit) as shown. Installassembled parts (13) in fill cap opening of hydraulic reservoir.h.Install flowmeter in loader cab.i.Set flowmeter controls as follows;RANGE switch in HI positionON/OFF switch in ON positionPRESSURE VALVE control completely openFLOW switch in FLOW positionj.Start and operate engine at idle speed.k.Press and hold flowmeter TEMPERATURE switchand watch flowmeter TEMPERATURE gage. Gageshould indicate 130 degrees. If indication isnot correct go to step 1 below; if gageindicates 130 degrees go to step m below.Before performing following steps, warn personnel to stay away fromsides of loader between front and rear chassis. Failure to do so willcause death or serious injury to those personnel due to chassis pivotingand crushing them. If personnel are injured, obtain medical assistanceimmediately.l.Depress accelerator pedal and increase engine speed to 1500 rpm. Turnsteering wheel completely to right until it cannot be turned anymore.Continue to hold steering wheel for a full right turn. Close flowmeterPRESSURE VALVE control until flowmeter PRESSURE gage indicates 1000 psi.Watch flowmeter TEMPERATURE gage while depressing flowmeter TEMPERATUREswitch. Continue to operate engine at 1500 rpm until flowmeter gage indi-cates 130 degrees then release accelerator pedal.m.Increase engine speed to full throttle.n.Turn steering wheel to right and slowly close flowmeter PRESSURE VALVEcontrol. As PRESSURE VALVE control is closed, flowmeter FLOW gage indicationwill slowly decrease. When loader relief valve begins to open, flowmeterFLOW gage reading will decrease rapidly. Stop closing flowmeter PRESSUREVALVE control and record flowmeter PRESSURE gage reading. This reading isthe pressure at which relief valve begins to open.3-507
