Preparation for Storage or Shipment (Cont)

Ensure the fuel tank contains at least 20 gallons (75.7L) of treated fuel. The fuel should be

(5)

treated with Biobor JF (MIL-S-53021) or equivalent as a fungus inhibitor. The addition of 3

teaspoons of Biobor JF to 20 gallons of fuel will provide adequate protection against fungus

growth. When storing a vehicle in freezing conditions, the addition of 3 ounces (88.7 ml) of

isopropyl alcohol (MIL-A-10-428) to 20 gallons of diesel fuel will help prevent fuel line freeze

up.

All fuel that is added to the vehicle during storage must be treated. While in storage, there

(6)

must always be at least 20 gallons (75.7L) of treated fuel in the vehicle's fuel tank.

Check condition of engine air cleaner. Service if necessary (para 4-3).

(7)

Coat all exposed unpainted surfaces such as crane valve spools, hydraulic cylinders, axle ball

(8)

sockets, drive shafts, and shift cables with grease.

CAUTION

Do not allow baking soda to enter the batteries or damage to the batteries will result.

Clean batteries and battery cables with a baking soda solution and rinse with fresh water. Add

(9)

water to battery electrolyte if necessary. Check the specific gravity of the batteries regularly.

Keep the batteries fully charged and clean (TM 9-6150-200-14).

Protect spare tire from direct sunlight.

(10)

If possible, store vehicles close together, out of direct sunlight, and away from electrical or

(11)

generating equipment.

Park vehicle to allow access for inspection, maintenance, and exercising.

(12)

CAUTION

Ensure tires are not resting on surface containing grease or oil. Failure to comply may

result in damage to tires.

Park vehicle so tires are not resting on surfaces containing grease or oil.

(13)

CAUTION

The alternator drains the batteries at all times. Batteries will discharge during storage if

not disconnected.

Disconnect batteries (para 7-90).

(14)

While

vehicle is in storage, perform the following tasks monthly:

(1)

Connect batteries (para 7-90).

(2)

If engine is run every 30 days or less, use lubricating oil OE/HDO (MIL-L-2104). If engine is

not run every 30 days or less, use preservative lubricating oil (MIL-L-21260C, Grade 2) and

change oil filter or warranty will not be maintained (LO 9-2320-279-12).

(3)

Conduct visual inspection of the vehicle. Check for oil leaks, lubricant levels, battery

electrolyte, coolant level, and tire pressures. Correct any discrepancies.

(4)

Inspect oil can points. Lubricate if necessary (LO 9-2320-279-12).

(5)

Shift transfer case to neutral, start engine, and idle for 10 minutes. After 10 minutes of engine

idle, operate engine for 5 minutes at 1500 rpm or until the engine water temperature reaches

180F (82C). Shift the transmission slowly through all gear selector positions. Return the

transmission to neutral and the transfer case to high range.

(6)

Move vehicle 30 feet (9 m) forward and reverse.

(7)

Idle engine 10 minutes before shutdown.

Check grease coating on all chromium plated and unpainted surfaces. If grease was wiped from

(8)

chromium plated or unpainted surfaces when vehicle was moved, recoat these surfaces.
