Preservation Specifications 79
Preservation of combustion chamber on new engines
• Clean engine if necessary.
• Fill with initial operation corrosion-inhibiting oil up to the “Min” mark at least.
• Clear access to the charge-air pipe. This may require removal of the flame-start canisters,
sensors, covers or pipes. Access to the charge-air pipe must be available after the intercooler,
after the pressure fine filter / air filter and after the turbocharger.
• Bar warm engine with starting equipment. The engine must not respond. This requires actuation of the
stop lever in the case of mechanical governors. With electronic governors, switch off the power supply
and turn the engine over either with the emergency start or another suitable method.
• While the engine is turning, fill with initial operation corrosion inhibitor oil in accordance with
the current MTU Fluids and Lubricants Specifications A001061/.. for approx. 15 seconds with
a fine atomizer spray gun into the charge air manifold openings.
• Drain initial operation corrosion inhibitor oil.
• Re-seal the openings to the charge-air m anifolds.
Preservation of cooling system, lubrication system and fuel system of engines from the field
• Clean engine if necessary.
• Drain engine oil.
• Fill with initial operation corrosion inhibitor oil in accordance with the current MTU Fluids and
Lubricants Specifications A001061/.. up to the Min. mark at least
• Fill the fuel system completely with diesel fuel
• When using a corrosion inhibiting antifreeze, leave it in the system; otherwise, drain coolant and fill the system
in accordance with MTU Fluids and Lubricants Specifications A001061/.. with corrosion inhibiting antifreeze
if there is a risk of frost. If there is no risk of frost, the customer’s coolant can be left in the system.
• Carry out the engine preservation run for approx. 10 mins at increased idling speed; the
coolant must reach at least operating temperature.
• Shut down engine.
• Leave corrosion inhibiting antifreeze in the system
• Drain initial operation corrosion inhibitor oil.
• Leave the fuel in the system.
Preservation of combustion chamber on engines from the field

• While the engine is turning, fill with initial operation corrosion inhibitor oil in accordance with
the current MTU Fluids and Lubricants Specifications A001061/.. for approx. 15 seconds with
a fine atomizer spray gun into the charge air manifold openings.
• Drain initial operation corrosion inhibitor oil.
• Re-seal the openings to the charge-air m anifolds.
In addition to the preservation steps, the following m easures must still be carried out:
in installed condition:
• Seal following openings tight against moisture:
• Cooling-air inlet
• Combustion-air inlet (close the emergency air shutoff flaps if they are provided)
• Exhaust outlet
with engine removed:
• Seal following openings tight against moisture:
• Cooling-air inlet
• Combustion-air inlet (close the emergency air shutoff flaps if they are provided)
• Exhaust outlet
• Electrical plug connectors
• Crankcase vent (with venting to atmosphere)
• Coat or spray non-painted parts with corrosion inhibitor for external preservation in accordance
with MTU F luids and Lubricants Specifications A001061/..
