PREPARING ENGINE FOR STORAGE
When an engine is to be stored or removed From operation for a period of Lime, special precautions should be taken to
protect the interior and exterior of the engine, transmission and other parts from rust accumulation and corrosion. The
parts requiring attention and the recommended preparations are given below.
It will be necessary to remove all rust or corrosion completely from any exposed part before applying a rust preventive
compound. Therefore, it is recommended that the engine be processed for storage as soon as possible after removal
The engine should be stored in a building which is dry and can be heated during the winter months. Moisture absorbing
chemicals are available commercially for use when excessive dampness prevails in the storage area.
TEMPORARY STORAGE (30 days or less)
To protect an engine for a temporary period of time, proceed as follows:
Drain the engine crankcase.
Fill the crankcase to the proper level with the recommended viscosity and grade of oil.
Fill the fuel tank with the recommended grade of fuel oil. Operate the engine for two minutes at 1200 rpm and
NOTE: Do not drain the fuel system or the crankcase after this run.
Check the air cleaner and service it, if necessary, as outlined under Air System.
If freezing weather is expected during the storage period, add a high boiling point-type antifreeze solution in
accordance with the manufacturer's recommendations. Drain the raw water system and leave the drain cocks
Clean the entire exterior of the engine (except the electrical system) with fuel oil and dry it with air.
Seal all of the engine openings. The material used for this purpose must be waterproof, vapor proof and possess
sufficient physical strength to resist puncture and damage from the expansion of entrapped air.
An engine prepared in this manner can be returned to service in a short time by removing the seals at the engine
openings, checking the engine coolant, fuel oil, lubricating oil, transmission, and priming the raw water pump, if used.
