Extended storage (vehicle inactive).

TM 9-2320-279-20-1

Preparation for Storage or Shipment (Cont)

(c) Operate all hydraulic equipment and steering system.

HD winch - winch out approximately ten feet of cable,

Model M984A1

then winch in. Repeat procedure twice.

Crane - completely cycle each crane function two times.

Retrieval system - completely extend and retract each cylinder

two times.

Self-recovery winch - winch out approximately six feet of

cable, then winch in. Repeat cycle two times.

Steering system - turn steering wheel to full right turn

and then full left turn. Repeat this cycle three times.

(d) If additional storage time is required, repeat steps (a) and (b) at yearly intervals.

(3)

Main hydraulic and steering hydraulic systems extended storage.

All models except M984A1.

CAUTION

To avoid overfilling, drain an amount of oil equal to amount being added before installing

additive or damage to equipment may result.

(a) Drain amount of oil from main hydraulic reservoir that is equal to the quantity

of additive being added.

(b) Add 6 qt (5.7L) VCI-326 vapor corrosion inhibitor (MIL-P-46002) or

equivalent to main hydraulic reservoir.

(c) Operate all hydraulic equipment and steering system.

All models except M984A1

Crane (if equipped) - completely cycle each crane function two times.

Self-recovery winch - winch out approximately six feet of cable, then

winch in. Repeat cycle two times.

WARNING

Do not operate pump without fuel in tank. Explosion with personal injury or death or

damage to equipment may result.

Tanker - if fuel is in tank, use pump to drain or recirculate fuel for a

minimum of one minute. If no fuel is in tank, do not operate pump.

Steering system - turn steering wheel to full right turn and then full

left turn. Repeat this cycle three times.

(d) If additional storage time is required, repeat steps (a) and (b) at yearly intervals.

(4) Crane extended storage.

(a) Coat all unpainted surfaces with corrosion preventative compound

(MIL-C-11796) or equivalent.

(b) Clean and touch up all paint defects to prevent rusting.

(c) Apply liberal amounts of grease to the solenoid valve button.

(d) Unwind hoist cable from drum, clean and lube with recommended lubricant

(MIL-L-2104), rewind on drum.

CAUTION

To avoid overfilling, drain an amount of oil equal to amount being added before installing

additive or damage to equipment may result.

(e) Add vendor recommended percentage of VCI-326 (MIL-P-46002) or equivalent

as a vapor corrosion inhibitor to crane swing drive [2 fl oz, (60 ml)] and hoist

gearboxes [0.8 fl oz, (24 ml)]. Operate crane to allow additive to coat all moving

parts.
