SECTION 7
INSTALLATION AND STORAGE
1. PREPARATION OF ENGINE FOR INSTALLATION.
Before installing an engine that has been prepared
for storage, remove all dehydrator plugs, bags of desiccant and preservative oil from the engine.
Preservative oil can be removed by removing the bottom spark plugs and turning the crankshaft three or
four revolutions by hand. The preservative oil will then drain through the spark plug holes. Draining will be
facilitated if the engine is tilted from side to side during the above operation. Preservative oil which has
accumulated in the sump can be drained by removing the oil sump plug. Engines that have been stored in a
cold place should be removed to an environment of at least 70°F (21°C) for a period of 24 hours before
preservative oil is drained from the cylinders. If this is not possible, heat the cylinders with heat lamps
before attempting to drain the engine.
After the sump has been drained, the plug should be replaced and safety-wired. Fill the sump with
lubricating oil. The crankshaft should again be turned several revolutions to saturate the interior of the
engine with the clean oil. When installing spark plugs, make sure that they are clean, if not, wash them in
clean petroleum solvent. Of course, there will be a small amount of preservative oil remaining in the engine,
but this can cause no harm. However, after twenty-five hours of operation, the lubricating oil should be
drained while the engine is hot. This will remove any residual preservative oil that may have been present.
CAUTION
DO NOT ROTATE THE CRANKSHAFT OF AN ENGINE CONTAINING PRESERVATIVE
OIL BEFORE REMOVING THE SPARK PLGUS, BECAUSE IF THE CYLINDERS
CONTAIN ANY APPRECIABLE AMOUNT OF THE MIXTURE, THE RESULTING
ACTION, KNOWN AS HYDRAULICING, WILL CAUSE DAMAGE TO THE ENGINE.
ALSO, ANY CONTACT OF THE RPESERVATIVE OIL WITH THE PAINTED SURFACES
SHOULD BE AVOIDED.
General
, containing crystals of silica-gel or similar material, be broken
during their term of storage or upon their removal from the engine, and if any of the contents should fall into
the engine, that portion of the engine must be disassembled and thoroughly cleaned before using the engine.
The oil strainers should be removed and cleaned in gasoline or some other hydrocarbon solvent. The fuel
drain screen located in the fuel inlet of the fuel injector should also be removed and cleaned in hydrocarbon
solvent. The operator should also note if any valves are sticking. If they are, this condition can be eliminated
by coating the valve stem generously with a mixture of gasoline and lubricating oil.
Inspection of Engine Mounting
engine has been removed, make sure
that the engine mount is not bent or damaged by distortion or misalignment as this can produce abnormal
stresses within the engine.
Attaching Engine to Mounts –
endations for method of mounting the
engine.
Oil and Fuel Line Connections –
The oil and fuel line connections are called out in the accompanying
installation drawings.
Propeller Installation –
Consult the airframe manufacturer for information relative to propeller installation.
