Fuel system extended storage.

TM 9-2320-279-20-1

Preparation for Storage or Shipment (Cont)

(c) Run the engine for approximately five minutes at 1500 rpm with the

transmission in neutral (N).

(d) Drive the vehicle. Make sure the transmission shifts thru all ranges.

(e) Continue running the engine at 1500 rpm with the transmission in neutral until normal

operating temperature is reached.

CAUTION

Do not allow transmission oil temperature to exceed 225F (107C) or damage to

transmission may result.

(f) If normal operating temperature is less than 225F (107C) shift the

transmission to forward range and stall the converter. Do not exceed 225F

(107C). Idle engine for approximately five minutes with transmission in

neutral (N).

WARNING

Ensure transmission is cool before proceeding. Failure to comply may result in injury to

personnel.

(g) As soon as transmission is cool enough to touch, seal all openings and the

breather with moisture-proof tape.

(h) Coat all exposed, unpainted surfaces with preservative grease such as

petrolatum (MIL-C-11796, Class 2).

(i) If additional storage time is required, repeat steps (b) thru (h) at yearly

intervals; except, it is not necessary to drain the transmission each year. Just

add VCI-329 (MIL-P-46002) or equivalent vapor corrosion inhibitor and

Biobor JF (MIL-S-53021) or equivalent as a fungus inhibitor.

Fuel system extended storage.

(a) Drain fuel tank.

(b) Change all fuel filters.

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

should be treated with Biobor JF (MIL-S-53021) or equivalent. The addition of

3 teaspoons of Biobor 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.

(d) Run engine 5 minutes to circulate clean treated fuel throughout the fuel system.

(e) All fuel that is added to the vehicle during storage must be treated. While in

storage, there must always be at least 20 gallons (75.7L) of treated fuel in the

vehicle's fuel tank.

(f) Cap off fuel system.

(10)

Engine extended storage.

(a) Change oil and filter (LO 9-2320-279-12). Add preservative lubricating oil

(MIL-L-21260C, Grade 2).

(b) Seal off turbocharger inlet and outlet connections with moisture resistant tape.

(11)

Battery extended storage (more than 30 days with no charging). Remove batteries from vehicle

(para 7-90) and keep fully charged (TM 9-6150-200-14).

(12)

Check the coolant level. Test the coolant to ensure that the cooling system is protected against

corrosion and temperatures down to -30F (-34C). Add antifreeze or corrosion inhibitors

compatible with ethylene glycol base antifreeze if cooling system is not adequately protected

(TB 750-651).
