TM 5-3895-373-34 2.45 REPAIR AUGER/CONVEYOR CONTROL VALVE- D. ASSEMBLE - Continued. 2. INSTALL SPOOL, TUBES, SLEEVES, AND ELECTRICAL COILS INTO VALVE BODY. 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. a. Lubricate all parts with clean hydraulic oil. Be    careful    not    to    damage    preformed packing     when     sliding     over     threads. Sharp    edges    of    thread    can    cut    or damage  preformed  packing.    Damaged preformed   packing   will   cause   leakage and affect performance. b. Install preformed packing (25) onto plug (24) and install  into  valve  body  (20).    Tighten  plug  to  35 Ib-ft (48 N•m). Do  not  drop  spool  or  allow  it  to  scrape across  threads  in  valve  body.    Handle spool  with  care.    Damage  to  surface  of spool     can     prevent     it     from     working properly. c.    Dip  spool  (23)  and  valve  body  (20)  into  clean hydraulic oil.  Install spool into valve body. d.    Install retainers (22) and springs (21) onto spool (23) inside valve body (20). Tubes are fragile and easily dented.  Use extreme caution when installing electrical    coils    onto    tubes.        Dented tubes may impair electrical coil operation. e.    Install  tubes  (18)  onto  valve  body  (20).    With crowfoot   wrench   at   a   90°   angle   to   torque wrench, tighten tubes to 35 lb-ft (48 N•m). f. Slide electrical coils (19) onto tubes (18). Thread   locking   compound   solvent   can cause eye damage. Wear safety goggles/glasses    when    using.        Avoid contact  with  eyes.    If  solvent  contacts eyes,   flush    eyes    with    water    and    get immediate medical attention. g.    Clean  threads  of  tubes  (18)  with  thread  locking compound solvent. Thread    locking    compound    can    cause eye damage. Wear safety goggles/glasses    when    using.        Avoid contact with eyes. If compound contacts eyes, flush eyes with water and get immediate medical attention. h.    Apply  thread  locking  compound  to  threads  of tubes (18). i.    Install sleeves (17) and hex nuts (16) onto tubes (18).  Tighten hex nuts to 12 lb-in (1,4 N•m).
