Tubes are fragile and easily dented.  Use extreme caution when removing electrical    coils    from    tubes.        Dented tubes may impair electrical coil operation. b. Slide electrical coils (19) from tubes (18). NOTE Spring  and  retainer  may  fall  from  valve body after tubes are removed. c. Use  the  combination  wrench  and  remove  tubes (18) from valve body (20). d. Remove   springs   (21)   and   retainers   (22)   from valve body (20). 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. e. Remove spool (23) from valve body (20). f. Remove  plug  (24)  and  preformed  packing  (25) from    valve    body    (20).        Discard    preformed packing. 4.
