Main- tenance of the oil filter is limited to replacement. Refer to paragraph 4-8. 4-52. OIL DRAINS. Maintenance   of the oil drains (figure 4-7) is limited to inspection and replacement. The oil drains  consist  of  the  reservoir  drain hose  and  the  output  pad  seal  drain. They are reached by removing the fuel/oil  drain  access  cover  on  the bottom   of   the   generator   set. The reservoir drain allows for draining of the gearbox. The output pad seal drain allows  for  drainage  of  oil  that  has seeped past the generator drive seal on the  gearbox. The oil drains should be inspected  for  damaged  threads,  hoses, and fittings each   time   the   oil   is changed. Refer to paragraph 4-8. 4-53. LINES AND FITTINGS ( EX- TERNAL). Maintenance  of  the  external lines and fittings  is limited  to inspection and replacement. The lubrication  system  lines  and  fittings consist of oil lines and flare adapter fittings used to connect the lubrication system to the oil cooler. 4-109
