SECTION VI. PREPARATION FOR STORAGE OR SHIPMENT
2-19. Administrative Storage. Prepare the winch assembly for storage in accordance with the following instructions:
a. Gearbox. It is always preferable to store speed reducers indoors. When this is not possible, or when storage is
for a period longer than 1 year, follow these instructions.
(1)
Reducers should never be exposed to the elements. They must be protected from the elements in some
manner. If stored outdoors, cover with a tarp that can be secured to the base of the reducer housing.
(2)
Remove plug from breather hole and attach a sufficient length of pipe to extend above the highest part of the
speed reducer.
(3)
Cap the pipe (pipe cap should be drilled and tapped for alemite fitting) and install alemite #317400 fitting to
relieve potential internal pressure.
(4)
Fill reducer completely with a heavy rust inhibitor such as Gulf No-Rust Engine Oil, Grade 3, which conforms
to Military Specification MIL-L-21260.
(5)
At least every 3 months rotate input shaft. Be sure the output shaft rotates more than one revolution. This is
done to ensure all internal parts are coated with fresh oil and that the shaft seals are free and the seal journals
are coated with oil.
(6)
At least every 3 months check the speed reducer for water condensation by removing lowest drain plug and
allowing small amount of oil to drain from the oil sump. All water that may have accumulated will be at bottom
of reducer housing and will drain out first.
(7)
Check all exposed fittings and shaft projections every 3 months for integrity of the protective coating. Reapply
coating if required, to prevent possible corrosion of shafts. Use Cosmoline 11-2 MIL-C-16173 Grade 2 or
equivalent.
Before starting the reducer, be sure to drain perservative oil and refill to proper level with the appropriate oil listed in the
lubrication instructions.
b. Hydraulic Power Pack.
(1)
Remove electrical power from the Hydraulic Power Pack and tag "Out of Service - Do Not Operate."
(2)
Drain hydraulic fluid from the reservoir (paragraph 2-17). Attach a tag stating that the reservoir has been
drained and unit cannot be operated until refilled.
