QTY REQUIRED FOR INITIAL OPERATION QTY REQUIRED FOR 8 HOURS OPERATION ARMY TM 9-611560412 NAVY NAVFAC P-833-12 Table 3-1.  Consumable Operating and Maintenance Supplies (Continued) Parts, 6850-00-281-1985 P-D-680, Dry (0) (0) (18) Cleaning Cleaning Solvent, 1.0 gal (3.8 L) 6850-00-285-8011 P-D-680, Dry (0) (0) (18) Cleaning Solvent, 55 gal (208 L) Parts, 9150-01-023-3934 VV-P-236, (0) (0) (19) Assembly Petrolatum NOTES (1) See Federal Supply Catalog C9100-1L for additional requisitioning data. (2) See Federal Supply Catalog C6800-1 L for additional requisitioning data (3) Fuel tank capacity is 130 gallons (492 L) (4) Average fuel consumption Is 55 gallons (208 L) per hour 8 hours continuous duty will require approximately 440 gallons (1665 L). (5) One tank, if required, for cold weather starting. (6) Crankcase capacity Is 30 gallons (113 L) plus 6 gallons (23 L) for the filters. (7) Total  cooling  system  capacity  Is  91  3  gallons  (345  6  L),  31  25  gallons  (118  3  L)  for  the  engine  block  and  51.8 gallons (196 1 L) for the radiator. (8) See Figure 3-2 for lube points (9) See Figure 3-2 for grade, application, and replenishment intervals (10) Each battery requires 4.1 gallons (15.5 L) of electrolyte. (11) One fuel strainer element is required at any given time.  Replace strainer tube every 300 hours, continuous duty cycle or every 6 months at standby duty (12) Four transfer pump fuel filter and two engine mounted fuel filter elements are required at any given time.  Replace transfer  pump  strainer  every  300  hours  for  continuous  duty  or  every  6  months  with  generator  set  at  standby duty (13) Two oil by-pass filters and four full-flow oil filters are used at any given time.  Replace all oil filter elements every 300 hours for continuous generator set duty or every 6 months for standby duty. (14) Two  primary  and  two  safety  air  cleaner  elements  are  used  at  any  given  time  Service  the   primary  elements whenever the air restriction indicators turn amber or red The primary elements may be cleaned and reused six times (or after two years, whichever comes first), after which they should be replaced Do not attempt to clean the safety elements.  Replace the safety elements after the primary elements have been changed three times. (15) New generator set engines are equipped with four DCA precharge water filter canisters which should be replaced with the DCA service filters (WF 2010) at the first oil change after initial operation.  Thereafter, replace the DCA service elements after 250 hours continuous duty or 6 months standby duty, whichever comes first. (16) Precharge  new  engine  coolant  whenever  the  cooling  system  is  drained  and  cleaned.    The  DCA-4L  precharge direct  chemical  additive  Is  used  for  this  purpose  and  is  compatible  with  either  plain  or  antifreeze-treated  water (except Dowtherm 209) Use 16 pints of DCA-4L additive to precharge the entire generator set cooling system (74 gallons (280L), approximate).  Use the precharge additive, also when storing make-up coolant in bulk. (17) The DCA coolant test kit is used to check DCA concentration In the engine coolant.  Draw coolant sample every 6 months and use the test kit to check effectivity of coolant filtering and DCA treatment.
