LYCOMING OPERATOR’S MANUAL SECTION 7
VO, IVO & TIVO-540 SERIES INSTALLATION AND STORAGE
NOTE
All engine cylinders should be preserved in the above manner, especially the nitride
hardened type cylinders which are more costly to manufacture and will require rebarreling if
rust and pitting are allowed to destroy the nitride layer on cylinder wall surfaces.
Installation of Seals and Plugs –
Install cylinder dehydrator plugs (Lycoming P/N 40238 or equivalent) in
spark plug holes. Install ignition cable protectors (Lycoming P/N 40239 or equivalent) over the spark plug
terminal of each ignition cable and secure by attaching to the end of the dehydrator plug. Flush all accessory
drives for which all oil seals are provided with preservative oil before assembling the drive covers. Make
sure that all other openings in the engine are properly sealed.
Exterior Surfaces – All exposed cadmium plated and machined surfaces should be coated with soft film
corrosion-preventative compound (E.F. Houghton and Col., Cosmoline 1059 or equivalent).
4. PREPARATION OF CARBURETORS AND FUEL INJECTORS FOR STORAGE OR SHIPMENT.
Carburetors – Drain all residual gasoline and replace plugs. Lock the throttle in the closed position and pack
in a suitable container.
Fuel Injectors – Remove plugs and drain all fuel from the injector. If available, apply 10-15 psi air pressure
to the fuel inlet until all fuel is discharged from the outlet.
Replace plugs and apply preservative oil (Specification MIL-0-6081, Grade 1010) through a 10 micron
filter at 13-15 psi to the fuel inlet until oil is discharged from the outlet. Replace inlet and outlet plugs and
pack in a suitable container.
CAUTION
DO NOT EXCEED THE RECOMMENDED AIR PRESSURES AS INTERNAL DAMAGE TO
THE INJECTOR MAY RESULT.
Shipping Case – Upon completion of the above procedures, the engine should be secured in a suitable
engine shipping container. The date of the preservation and the following legend should be legibly marked
on the side of the container.
“On (date) this engine was preserved for 60 days short term storage with preservative
oil and cylinder dehydrator plugs. The dehydrator plugs shall be inspected on arrival at
destination or 30 days from the above date (whichever occurs sooner) to determine if
renewal of the dehydrating agent is necessary.”
Recommended Procedure for Re-Preservation –
The engine shall be examined every 30 days (or less
depending on weather and locality). If any evidence of corrosion is present the affected area shall be cleaned
free of corrosion and the engine re-preserved.
Engines prepared by the above procedure are not adequately protected for extended periods of storage. If
at the end of 60 days it is found that the engine must remain in storage for an additional period, the engine
must be re-preserved according to the foregoing procedure.
