Preservation of Diesel Engine:

1. Lubricating oil system.

Lub. oil is drained from base frame, lub. oil filter and cooler.

After cleaning of the engine and the base frame, a rust-preventing lubricating oil is added, and the entire lub. oil system is primed.

The oil is just covering the bottom of the base frame.

The following types of oils are suitable:

Esso Rustban 335.

Chevron EP Industrial Oil 68.

Shells Ensis Oil SAE 30 / SAE 10 W.

Mobilarma 524.

BP Protective Oil 30/40.

2. Fuel oil system.

The fuel oil is drained. The fuel valves are cleaned and pressure tested with Mobil White-Terex 309 or similar, and the entire fuel oil system is filled with this type of oil.

3. Bright components internal or external on the diesel engine such as crankshaft, camshaft and gear wheels are covered with Mobilplex 44 or similar.

4. Bags with a hygroscopic product are suspended inside the diesel engine in the crankcase. The bags are equipped with a humidity indicator.

SilicaGel or a similar product can be used in a quantity of 3000 grams/m3.

The bags must not touch any surfaces, and if necessary the surface is covered with a plastic sheet.

5. All external surfaces are sprayed with a protective layer of Mobilarma 247 or similar.

6. All openings and flange connections are carefully closed.

7. Electric boxes are protected inside by volatile corrosion inhibitor tape.

Spare parts and tools.

Preservation of supplied spare parts and tools are made as follows:

overall machined parts are dipped in Mobilarma 633

partly machined parts are sprayed with Mobilarma 245

special tools in boxes are protected by a volatile corrosion inhibitor tape

Storage conditions

The boxes must always be stored under roof, protected from direct rain, sea-fog and dust. The boxes must be covered with tarpaulin.

Maintenance of preservation

Immediately upon arrival the boxes are to be opened and the parts examined for damage to the preservation, and if necessary repaired.

This procedure must be repeated every 2-4 months depending on the storage conditions.

Smaller boxes containing special tools such as:

grinding machine for valve seats

indicator

test equipment for fuel valves

measuring equipment

etc.

must be removed from the shipment, inspected for corrosion and stored in a dry place.

After inspection the boxes with the spare parts must be closed and covered with tarpaulin.

Cleaning of parts can be made with petroleum, turpentine or similar solvents.

Notice:Special preservation can be made on request.
