START THE PORT PROPULSION PLANT
1.
Ensure that the air compressors are online and that the starting air receivers are pressurized to 250 PSI (17.2 bar). If the
compressors are not online or the starting air receivers are not charged, START the air compressors (TM 55-1925-286-
13&P).
2.
Check that the coolant level in the port main engine coolant expansion tank sight glass (figure 1, item 1) is between
LOW and FULL in the STOP range (figure 1, item 2). If the coolant is not between LOW and FULL, add coolant
through the fill cap (figure 1, item 3) until the proper level is achieved. Proper engine coolant is a 50/50 mix of ethylene
glycol antifreeze and water.
3.
Check that the port main engine oil is at the normal level on the dipstick (figure 13, item 1). If the engine oil level is low,
add oil until the proper level is achieved. Refer to TM 55-1925-208-24 or maintenance supervisor for oil specification.
4.
Check that the port reduction gear oil is at the normal level on the dipstick (figure 13, item 2). If the reduction oil is level
low, add oil until the proper level is achieved. Refer to TM 55-1925-223-24&P or maintenance supervisor for oil
specification.
