ENGINE STORAGE
Preparing Engine For Storage
When an engine is to be stored or removed from
operation for a period of time, special precautions
should be taken to protect the interior and exterior of
the engine and other parts from rust accumulation and
corrosion. The parts requiring attention and the recom-
mended preparations are given below.
It will be necessary to remove all rust or corrosion
completely from any exposed part before applying a
rust preventative compound.
Therefore, it is recommended that the engine be proc-
essed for storage as soon as possible after removal
from operation.
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 damage prevail in the storage
area.
Temporary Storage (30 Days Or Less)
To protect an engine for a temporary period of time,
proceed as follows:
1. Drain the engine crankcase.
2. Fill the crankcase to proper level with the recom-
mended viscosity and grade of oil.
3. Fill the fuel tank with the recommended grade of
fuel oil. Operate the engine for two minutes at
1,200 rpm and no load. Shut down engine, do not
drain the fuel system or the crankcase after this
run.
4. Check the air cleaner and service it, if necessary.
5. If freezing weather is expected during the storage
period, add an ethylene glycol base antifreeze
solution in accordance with the manufacturer’s
recommendations.
6. Clean the entire exterior of the engine (except the
electrical system) with fuel oil and dry it with
compressed air.
To prevent possible personal injury, wear adequate
eye protection and do not exceed 40 psi (276 kPa)
compressed air pressure.
7. Seal all of the engine openings. The material used
for this purpose must be waterproof, vaporproof
and possess sufficient physical strength to resist
puncture and damage from the expansion of en-
trapped air.
An engine prepared in this manner can be returned to
service in a short period of time by removing the seals
at the engine openings, checking the engine coolant,
fuel oil, lubricating oil, transmission oil and priming the
raw water pump (if used).
Extended Storage (more Than 30 Days)
To prepare an engine for extended storage, (more than
30 days), follow this procedure:
1. Drain the cooling system and flush with clean, soft
water. Refill with clean, soft water and add a rust
inhibitor to the cooling system.
2. Remove, check and recondition the injectors, if
necessary, to make sure they will be ready to
operate when the engine is restored to service.
3. Reinstall the injectors, time them and adjust the
exhaust valve clearance.
