 TM 55-1905-223-24-1
(i)
Start engine (TM 55-1905-223-10) and operate at idle for 3 minutes. Stop engine and fill to high
mark. Additional oil may be required to fill oil filters and lines.
NOTE
The above procedure determines dipstick gauge marking for oil pan capacity only. Do not confuse
with complete oil system capacity which also includes drilled passages, lines, and filters.
(4)
Check Air Connections. Check for loose clamps or connections; cracks, punctures, or tears in
hoses or tubing; collapsing hose; or other damage. Tighten clamps or replace parts as necessary
to ensure an airtight air intake system. Make sure that all air goes through the air cleaner.
(5)
Check Engine Coolant.
(a)
Observe the sight level gauge on the expansion tank located on top of EOS to check engine
coolant supply.
CAUTION
Do not, under any circumstances, add a large amount of cold water to a hot engine suddenly.
The rapid cooling may crack the cylinder liner and head or seize the piston.
(b)
If coolant level is low, check for evidence of coolant leakage around tubing, hose connections,
etc.; correct as necessary. Inspect water pump bleed hole for leakage; leakage indicates a worn
or damaged seal. Fill the expansion tank to the proper level as indicated in the sight glass on
the coolant expansion/fill tank.
(6)
Check Fuel Supply and Connections. Visually check for evidence of external fuel leakage at fuel
connections and tighten as necessary. Inspect hoses and tubing for damage and replace as
necessary.
c.
Starting the Engine. After the above actions are taken, the engine is ready to start.
WARNING
Ensure that all personnel are clear of the engine, the marine
gear is disengaged, and appropriate operations personnel are
notified before starting the engine.
CAUTION
Protect the engine and engine components during start-up by
idling until normal idle oil pressure (20 psi minimum) is obtained.
Do not prolong idling unnecessarily. Operation at low
temperatures can result in serious damage.
