TM  5-6115-584-12 NAVFAC  P-8-622-12 TO-35C2-3-456-1 TM-05682C-12 plug  is  clean  and  tight.  Check  for  leakage  where  the glow  plug  enters  cylinder  head. b.  Test.  Remove  electrical  lead  to  glow  plug.  Use ohmmeter   to   test   for   continuity.   from   terminal   of glow plug and ground, Open circuit indicates bad glow plug. With  master  switch  in  the  PREHEAT  position, 24 volts dc is applied to the glow plug body. Do not  handle  plug  with  the  master  switch  in  the PREHEAT position. c.  Remove.  Disconnect  lead  to  glow  plug.  Unscrew glow  plug  and  remove  it  from  cylinder  head.  If  glow plug  was  leaking  where  it  entered  cylinder  head,   re- move  gasket  with  a  hooked  wire  and  replace. d. Install, If gasket (2, figure 4-42) has been removed, place new  gasket  over  glow  plug.  Coat  plug  threads  with  anti-seize compound and screw glow plug into cylinder head. Tighten glow plug 10 to 15 ft-lb dry. Attach electrical lead to plug. On ASK equipped generators, install top panel assembly (para. 5-4). 4-49. OIL DRAIN HOSE VALVE. a.  Replace  (see  figure  3-20).  On  ASK  equipped  gener- ators, remove oil access door, Drain engine 011 Into a suitable container.   Disconnect   oil   drain   hose   from   valve.   Remove valve.  Attach  serviceable  hose  to  valve.   Use  pipe  thread sealant on allpipe threads, Always store hose against frame when not in use. 1.  Oil  level  indicator 4 .    O i l    f i l l 2.

Inspect.  Inspect  oil  base  for  dents,  cracks,  or other physical damage. Check  for leaks, especially at the gasket between oil base and cylinder block. 4-51.  OIL  PILL  TUBE. a.  Remove  (see  figure  4-43).  On  ASK  equipped  gener- ators, remove oil access door. Remove oil level indicator (1). Remove screw (2), and Iockwasher (3). Remove oil fill tube (4) and scrape gasket (5) from mating surface on cylinder block (6) and oil fill tube (4). b. Installation.  Install  gasket  (5)  between  oil  fill tube (4) and cylinder block (6).  Attach oil fill tube (4) with  screw  (2) and  lockwasher  (3).  Install  oil  level indicator (1) in oil fill tube (4). 4-52. ENGINE  MOUNTING  ASSEMBLY. a. Inspect  (see  figure  4-44).  On  ASK  equipped  gener- ators, remove cover assembly. (para 5-3). Check to see that mounting nuts and bolts are tight. Cheek rubber mounts (14) for  cracks  and  breaks. (1),  lockwasher (3),  flatwasher  (2)  and  nuts  (4)  that secure each mounting assembly to skid-base (5). Re- move screws (6),  lockwashers  (7)  and  flatwashers  (8) and remove mounts. c.  Disassembly.  Remove  screw   (9),   nut   (10),   lock- washer (11) and  flatwasher  (12).  Remove  brackets (13).  Remove  resilient  mounts  (14)  and  spacer  (16) from bracket (17). Do not remove alignment pin (15), unless it is damaged. d. Reassembly. Install mounts (14) and spacer (16) into  bracket  (17).  Using  screw  (9),  flatwasher  (12), lockwasher (11) and nut (10), assemble brackets (13) to the mount. e. Installation. Install mounts on engine and secure with screw (6), Iockwasher (7) and flatwasher (8). Lower engine and mounts to skid-base and secure mounts to base with screws (1), washers b. Remove.  Use  engine  lifting  assembly  to  remove weight off of mounting assembly and remove screws 4-54 Change 7 (2), Iockwashers (3) and nuts (4). On ASK equipped generators, install ASK cover assembly (para 5-3).
