SHORT TERM STORAGE (30 DAYS OR LESS) - Continued
Check the air cleaner and service it if necessary.
If freezing weather is expected during the storage period, check the antifreeze for the low freeze point capability.
Clean the entire exterior of the engine (except the electrical system) with fuel oil and dry it with
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 entrapped air.
The following procedures will prepare a transmission for a storage period of 30 days or less:
Drain the transmission oil and remove the transmission oil filter element.
Install the drain plugs and new oil filter element.
Refill to operating level with lubricating oil.
DO NOT allow temperature to exceed 250°F (121°C). Failure to follow this caution may result
in damage to equipment.
Operate the unit for at least 5 minutes at a minimum of 1,000 rpm. Shift the transmission slowly through all
selector positions to thoroughly distribute the oil, then stall the converter to raise the oil temperature to
As soon as the unit is cool enough to touch, seal all openings and breathers with moisture-proof tape.
Coat all exposed, unpainted surfaces with a good grade of preservative grease.
END OF TASK
LONG TERM STORAGE (MORE THAN 30 DAYS)
Long-term storage requires greater preparation than short-term storage and must be
undertaken with greater care.
The crane should be prepared as follows:
Perform the short-term vehicle storage preparation, making certain that all points with grease fittings are
liberally lubricated in this work package.
Drain and refill the swing reducer, winch, axle differentials, planetary hubs, and hydraulic reservoir.
Distribute new hydraulic oil to all parts of the system by operating all functions.
Clean the batteries and battery cables with a baking soda solution and rinse them with fresh water. Do not
allow the soda solution to enter the battery. Add distilled water to the electrolyte, if necessary, and fully charge
Coat the external ring gear of the swing bearing with open gear lubricant.
Fill the hydraulic reservoir to the top after the vehicle is parked in its storage spot.
Coat wire rope with lubricant (TM 5-3810-305-10).
Coat exposed cylinder rods with grease.
