(2) Disconnect hose from right port A on top of right outrigger jack cylinder. (3) Connect hydraulic tester between hose and port P with test hoses and adapters. (4) Start engine (TM 9-2320-366-10-1). (5) Position PTO switch to on (TM 9-2320-366-10-1). (6) Increase engine rpm to 1250-1450 rpm (TM 9-2320-366-10-1). (7) Position MHC power switch to ON (TM 9-2320-366-10-1). (8) Lower right outrigger (TM 9-2320-366-10-1). (a) During lowering, observe reading of 3-4 gpm (11-19 lpm) at negligible pressure. As outrigger loads, pressure will rise. (b) If flow is low, replace control valve in three way (lower control) valve assembly. (9) Raise outrigger (TM 9-2320-366-10-1). (10) Position MHC power switch to OFF (TM 9-2320-366-10-1). (11) Position PTO switch to off (TM 9-2320-366-10-1). (12) Shut down engine (TM 9-2320-366-10-1). (13) Disconnect hydraulic tester, hoses and adapters. (14) Connect hose to port A. (15) Remove drain pan from under vehicle. WARNING Wear approved eye protection when performing pressure checks. Failure to comply may result in oil getting into eyes. If oil contacts eyes, seek medical attention immediately. Drop hydraulic pressure to zero before disconnecting any hydraulic hose, tube, or fitting. Failure to comply may result in injury to personnel. Fuel and oil are slippery and can cause falls. Wipe up spilled fuel or oil with rags. Failure to comply may result in injury to personnel. Check position of right outrigger to verify that it is held in the stowed position. If right outrigger will not remain stowed over a period of time, holding valve (in outrigger jack cylinder) is faulty.
