TM 5-3895-373-34 B. ADJUST - Continued. 5. ADJUST AUGER/CONVEYOR RELIEF VALVES. NOTE This   procedure   applies   to   both   left hand  and  right  hand  auger/conveyor relief valves. a. Remove valve cap (17). CAUTION Use    caution    when    removing    seals and preformed packings.  Do not use excessive force when removing seals and  preformed  packings.    Use  an  o- ring tool to remove seals and preformed packings. b. Use an o-ring tool to remove preformed packing (18) from valve cap (17). c. Remove compression nut (19). d. Use an o-ring tool to remove preformed packing (20) from compression nut (19). e. Turn adjustment screw (21) clockwise to increase  relief  valve  setting  or  counterclockwise to decrease relief valve setting. f. Set auger/conveyor relief valves (22) to 2750 psi (18 961 kPa). WARNING Hydraulic oil can be moderately flammable and can  be  an  irritant to the skin, eyes, and respiratory system.  Avoid prolonged exposure. Eye  protection  and  rubber  gloves  must  be  worn  when working with hydraulic oil. g. Lubricate  preformed  packings  (18  and  20)  with clean hydraulic oil. h. Install   preformed   packing   (18)   onto   valve   cap (17). i. Install preformed packing (20) onto compression nut (19). CAUTION Be  careful  not  to  damage  preformed packings  when  sliding  over  threads. Sharp   edges   of   threads   can   cut   or damage preformed packings. Damaged    preformed    packings    will cause leakage and affect performance. j. Install compression nut (19) onto auger/conveyor relief valve (22). k. Recheck pressure setting. l. Install valve cap (17).  Tighten valve cap. GO TO NEXT PAGE 2-687
