Diesel Generator Starting
! CAUTION
Do not use starting fluid with the diesel generator engine. The diesel generator engine
uses preheat elements to assist with cold weather starting. Use of starting fluid in
conjunction with these preheat elements will cause serious internal engine damage.
No special cold weather starting procedures are required for starting the diesel generator engine. The starting procedures
contained in WP 0023 00 apply to all weather conditions. Do not use starting fluid with the diesel generator engine. The
diesel engine uses preheat elements to assist with cold weather starting. Use of starting fluid in conjunction with these
preheat elements will cause serious internal engine damage.
Propulsion Engine and Diesel Generator Engine Lubricating Systems
Consult O203 03/97 for special lubrication requirements for the diesel generator engines.
Consult TM 5-2815-231-14 for special lubrication requirements for the propulsion engines.
Cooling Systems
Proper antifreeze level must be maintained in all engine cooling systems. Consult the PMCS contained in WP 0053 00 and WP
Raw Water Systems
If the temperature in the engine room can be maintained above freezing by occasional operation of the propulsion engine or
by operation of the diesel generator, no precautions are necessary for the raw water systems. If the engine room temperature
can not be maintained above freezing, preserve the raw water systems as described in TB 740-97-4.
Batteries
A fully charged battery will not freeze until its temperatures reaches -75 F (-59.4 C). A battery with a 50% charge will
freeze at 5 F (-15.0 C). It is important to keep the batteries charged in order to prevent freezing. If 220 Vac power is
available via the diesel generator or shore power, the main batteries may be kept charged with the battery charger. The diesel
generator starting battery is not charged by the battery charger. This battery must be kept charged by occasional operation
of the diesel generator engine.
Hydraulic Systems
During cold weather, allow all hydraulic systems to run unloaded for at least 15 minutes. This will allow time for the oil to
warm up and will prevent damage to hydraulic components due to lack of lubrication.
Potable Water System
If the vessel has 220 Vac power available via the diesel generator or shore power, the heat/air conditioning systems may be
operated to warm the accommodation module. This will prevent freezing of the potable water system. If 220 Vac power is
not available, if the heat/air conditioning system is inoperative, or if the heat/air conditioning units are unable to maintain the
accommodation module at a temperature above freezing, preserve the potable water system as described in TB 740-97-4.
Black Water System
If the vessel has 220 Vac power available via the diesel generator or shore power, the heat/air conditioning systems may be
operated to warm the accommodation module. This will prevent freezing of the black water system. If 220 Vac power is not
available, if the heat/air conditioning system is inoperative, or if the heat/air conditioning units are unable to maintain the
accommodation module at a temperature above freezing, preserve the black water system as described in TB 740-97-4.
Steering System
Before getting underway, test the steering system by moving the wheel from full port to full starboard. Observe the rudder
angle indicator during this operation to make sure that the rudder moves through its full range of motion. Turn the wheel
slowly at first to free the rudder from any ice which may have formed between the hull and the rudders at the waterline.
