TM 5-2420-222-34 14-1. HYDRAULIC SYSTEM TEST. This Task Covers:  Test Initial Setup: Tools/Test Equipment: Materials/Parts: General mechanic's tool kit Rags (Item 28, Appendix B) Field automotive shop set Hydraulic system tester References: TM 5-2420-222-10 TM 5-2420-222-20 TEST WARNING Do not attempt to disconnect hydraulic hoses and fittings while engine Is running  or  before  hydraulic  system  pressure  has  been  released.    When engine Is running, hydraulic system Is under pressure.   Hydraulic  system pressure should be 0 psi (0 kPa) before lines are disconnected.  A line or fitting disconnected under pressure will spray hydraulic fluid with force and may cause serious injury to personnel. Be  careful  when  draining  hot  fluids.    Wear  gloves  to  protect  your  hands from hot parts and fluids.  Severe burns could result. NOTE Purpose of test is to give Indication of no flow condition for entire hydraulic system. Flow Indication from hydraulic system tester will require hydraulic components to be Isolated and checked for leakage. Backhoe  test  may  be  Isolated  by  performing  steps  14  through  39  and connecting the hydraulic system tester to the backhoe. Use a drain pan to catch fluid when disconnecting hydraulic hoses.  Clean up all spills. 1. Release hydraulic system pressure (see TM 5-2420-222-20). 2. Disconnect hose (1) from special tee (2). 3. Connect hydraulic system tester to hose (1) and special tee (2). 4. Start engine assembly and run at 2500 rpm (see TM 5-2420-222-10).  Run engine until operating temperature is 170-F-190-F (77°C-88oC). 5. Check  connections  of  hydraulic  system  tester,  hose  (1),  and  special  tee  (2)  for  leaks.    Tighten  any  leaking connections. 6. Position all loader backhoe hydraulic levers in neutral (see TM 5-2420-222-10). 7. Check hydraulic system tester for indication of no flow.  If flow Is present, individual components must be isolated and checked for leakage. 8. Shut down engine assembly (see TM 5-2420-222-10). 14-2
