provide the power unit maximum protection from the elements.
4-4. Inspection and Maintenance of Equipment in Storage
When the item has been placed in limited storage, all scheduled preventive maintenance services, including inspection,
shall be suspended and preventive maintenance inspection shall be performed as specified herein. Perform quarterly
preventive maintenance services when 'the item is initially placed in limited storage and every 90 days thereafter.
Record all deficiencies and shortcomings together with corrective action taken, on DA Form 2404. Required
maintenance will be performed promptly to insure that the item is mechanically sound and ready for immediate use. At
the time of quarterly inspection and maintenance, operate the item long enough to bring it up to operating temperature
and insure complete lubrication of all bearings, gears, etc. After each operating period, represerve the item as outlined in
Section II. DEMOLITION OF MATERIAL TO PREVENT ENEMY USE
When capture or abandonment of the power unit to the enemy is imminent, the responsible unit commander must make
the decision to destroy the equipment or to render it in-operative. Based on this decision, orders are issued which cover
the desired extent of destruction. Whatever method of demolition is employed, it is essential to destroy the same vital
parts of all power units and all corresponding repair parts.
Material will not be destroyed except upon order of proper authority.
4-6. Demolition to Render the Power Unit Inoperative
Demolition by Misuse. Perform the following steps to render the unit inoperative:
Remove oil filler cap (fig. 1-3) and screen.
Pour water, sand, or dirt in oil tank and replace oil filler cap.
Let the engine run until failure occurs.
Demolition by Mechanical Means. Use sledge hammers, crowbars, picks, axes, or other heavy tools which may
be available, together with the tools normally included with the power unit to destroy the following:
Fuel and oil filters, tanks, pumps and strainers.
Starter, battery, upper rack assembly and lower rack assembly.
Fuel atomizer assembly and combustion assembly.
Accessory housing, compressor assembly and turbine assembly.
Instrument panel, conditioned air system circuit breaker panel and electrical control components panel,
electrical output connection panel, and remote power connection panel.
Refrigeration compressors, condensers and condenser fans, evaporators and recirculating fans and
4-7. Demolition by Explosives or Weapons Fire
Demolition by Explosives. Place the required charges to destroy the power unit as shown in figure 4-1.
Demolition by Weapons Fire. Fire on the power unit with the heaviest suitable weapons available.
4-8. Other Demolition Methods
Scattering and Concealment. Remove all easily accessible vital parts. Scatter them through dense foliage, bury
them in dirt or sand, or throw them into a lake, stream, well, or other body of water.
Submersion. Totally submerge the power unit in a body of water to provide water damage and concealment.
Salt water will do greater damage to metal parts than fresh water.
Burning. Pack rags, clothing, or canvas around and under the engine, the generators, in the engine air inlet
compartment, in the refrigeration compartment, and around the refrigeration compressors. Saturate this packing with
gasoline, oil, diesel fuel, or other available inflammable fluid and ignite.
