80 Preservation Specifications

• Seal check sheet in a clear plastic envelope and attach to engine at a clearly visible location.

• Complete the check sheet after completion of preservation work.

• Seal supply and drain lines of:

• Coolants

• Fuel

• Engine oil

Preserving diesel engines

• Remove sealed covers from combustion-air inlet and exhaust outlet.

• Preserve combustion chamber (see item Preservation of combustion chamber).

• Seal off the combustion air intake and exhaust outlet openings against moisture / humidity once again.

• Fill the cooling circuit with an external pump with corrosion inhibiting antifreeze, or fill 100% with

customer’s coolant (without antifreeze if there is no risk of frost).

• Leave corrosion inhibiting antifreeze in the system

Represervation of the cooling system is not necessary with further represervation replenishments.

Before return to service, the engine must be depreserved. The following steps must be carried out:

• Clean engine if necessary.

• Remove all sealing covers

• Drain off remaining corrosion-inhibiting oil.

• Fit new oil filters (inserts) (not applicable f or new deliveries; after 1 year at latest).

• Fill up with engine oil.

• Bar engine manually.

• Prepare engine for operation.

• Renew coolant

Note

Put engine into operation according to the engine documentation.

Preserving gas engines

The same specifications as for preservation or represervation of diesel engines apply.

The following section lists deviations from the above-named specifications.

Preservation of cooling system and lubrication system of new engines

• Clean engine if necessary.

• Completely fill cooling system with inhibitor concentrate Glysacorr P 113 (9-11% by

vol.) and water ( 91 – 89% by vol.).

• 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.

• Run the engine for 15 minutes at half load.

• Shut down engine.

• Allow engine to cool to max. 40 °C.

• Drain the inhibitor concentrate.

• Drain initial operation corrosion inhibitor oil.

If there is danger of frost, fill up with antifreeze (40%)! (Only for installed engines)

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.

• Use the starting system to bar the engine. The engine must not respond. To ensure this, the

gas supply m ust be reliably interrupted by closing the gas line.
