1. Required tools, preservation, cleaning and auxiliary means
1.1 spray gun, injection pipe, brush
1.2 preserving oil that can be sprayed and does not dry (e.g. Aral Konit SAE 30)
1.3 a viscous, sticking and drying preservative (e.g. Valvoline Tectyl 506)
1.4 corrosion-inhibiting oil (e.g. Rust Ban 310)
1.5 ethylene glycol inhibitor (e.g. Glysantin)
1.6 slovent-free cleaning and/or washing agent
Attention:
The engine finish may not be etched by cleaning and/or washing agent!
Use only suitable washing agents!
Keep to the operation, safety and sanitation instructions of the manufacturer!
2. Preservation measures engine
The preservation measures for the individual engine components are to be carried out
according to the following sequence of operations.
2.1 Fuel system
• In case of heavy fuel driven engine, switch over to destilled fuel, see A3.06.07.nn .
• Clean fuel duplex filter, see A5.05.07.12.01.nn .
• Mix destilled fuel and corrosion inhibiting oil in a ratio of 1 : 1 , see 1.4.
The required quantity of fuel “B” (liters) for 15 - 20 min. running time depends on the
engine type and may be calculated by the following formula:
•
Empty the destilled fuel day tank and fill it with with the mixture of fuel/corrosion inhibiting
oil.
•
Operate warmed up with the fuel/corrosion inhibiting oil at
75 %
of the nominal revolution
speed at a low load.
•
Monitor the level in the day tank and stop the engine, ensuring that the fuel system (piping
and equipment) remain full.
Note:
If the engine is seperated from the plant, run the engine until the fuel system is
empty. Then firmly seal the connection points with plastic plugs!
