Series 50 – Section 14.1 Preparing Engine for Storage

Section 14.1
Preparing Engine for Storage

When an engine is to be stored or removed from operation for a period of time, special precautions should be taken to protect the interior and exterior of the engine, transmission and other parts from rust accumulation and corrosion. The parts requiring attention and the recommended preparations are given below:‪

  • It will be necessary to remove all rust or corrosion completely from any exposed part before applying rust preventive compound. Therefore, it is recommended that the engine be processed for storage as soon as possible after removal from operation.
  • The engine should be stored in a building that is dry and can be heated during the winter months. Moisture absorbing chemicals are available commercially for use when excessive dampness prevails in the storage area.

Section 14.1.1
Temporary Storage (30 Days or Less)

To protect an engine for a temporary period of 30 days or less, proceed as follows:‪

  1. Drain the engine crankcase. Refer to "13.5.1 Lubricating Oil" .
  2. Fill the crankcase to the proper level with the recommended viscosity and grade of oil listed in Table "Recommended Engine Oil" .
  3. Fill the fuel tank with the recommended grade of fuel oil listed in Table "Fuel Oil Selection Chart" . Operate the engine for two minutes at 1200 r/min and no load.

    Note: Do not drain the fuel system or the crankcase after this run.

  4. Check the air cleaner and service it, if necessary. Refer to OEM guidelines.
  5. If freezing weather is expected during the temporary storage period, add an ethylene glycol base antifreeze solution to the cooling system in accordance with the manufacturer's recommendations. Otherwise, the coolant system should be flushed and filled with a good rust inhibitor to prevent rusting of the outside diameter of the cylinder liners. Refer to "13.5.4 Cooling System" .
  6. Remove electrical components. Refer to "8 Electrical Equipment" .
  7. Clean the engine exterior of the engine (except electrical components) with fuel oil.
  8. Seal all of the engine openings with a material used for this purpose. The material used for sealing must be waterproof, vapor proof and possess sufficient physical strength to resist puncture and damage from the expansion of entrapped air.

Section 14.1.2
Restoring a Temporarily Stored Engine

An engine that was stored in accordance with the DDC guidelines for temporary storage can be returned to service in a short time by removing the seals at the engine openings and by checking the engine coolant, fuel oil, lubricating oil and transmission oil levels. (Refer to "14.1.1 Temporary Storage (30 Days or Less)" .)‪

Section 14.1.3
Extended Storage (More Than 30 Days)

To prepare an engine for extended storage (more than 30 days), follow this procedure:‪

  1. Drain the cooling system. Refer to "13.5.4 Cooling System" .
  2. Flush with clean, soft water. Refer to "13.5.4 Cooling System" .
  3. Refill with clean, soft water and add a rust inhibitor to the cooling system. Refer to "5.4 Coolant" .
  4. Circulate the coolant by operating the engine until normal operating temperature is reached, listed in Table "Series 50 Operating Conditions" .

    Table 1. Series 50 Operating Conditions
  5. Stop the engine.
  6. Remove the drain plug to drain the engine crankcase. Refer to "13.5.1 Lubricating Oil" .
  7. Install and tighten the 3/4 in.-14 square, magnetic oil drain plug to 45-56 N·m (33-41 lb·ft) torque.
  8. Install new lubricating oil filters. Refer to "13.5.1 Lubricating Oil" .
  9. Fill the crankcase to the proper level with a 30-weight preservative lubricating oil MIL-L-21260C, Grade 2. Refer to "13.5.1 Lubricating Oil" .
  10. Drain the fuel tank. Refer to "13.5.2 Fuel Tanks" .
  11. Refill with enough clean No. 1 diesel fuel or pure kerosene to permit the engine to operate for about ten minutes. If it isn't convenient to drain the fuel tank, use a separate, portable supply of recommended fuel.

    Note: If engines in vehicles are stored where condensation of water in the fuel tank may be a problem, supplemental additives containing methyl carbitol or butyl cellusolve are effective. Follow the manufacturer's instructions for their use. The use of isopropyl alcohol is no longer recommended due to its negative effect on fuel lubricity.

    Note: In environments where microbe growth is a problem, a fungicide such as Biobor JF (or equivalent) may be used. Microbial activity may be confirmed with commercially available test kits. Follow the manufacturer's instructions for treatment. Avoid the use of fungicides containing halogenated compounds, since these may cause fuel system corrosion.

  12. Drain the fuel system. Refer to "13.5.2 Fuel Tanks" .
  13. Remove the fuel filters. Refer to "2.7.1 Replacement of Fuel Filter" .
  14. Discard the used filters.
  15. Fill new filters with No. 1 diesel fuel or pure kerosene.
  16. Install new oil filters on the engine. Refer to "13.5.1 Lubricating Oil" .
  17. Operate the engine for five minutes to circulate the clean fuel oil throughout the engine. Ensure the engine fuel system is full.
  18. Disconnect the fuel return line and the inlet line at the primary filter and securely plug both to retain the fuel in the engine. Refer to "13.5.3 Fuel Lines and Flexible Hoses" .
  19. Service the air cleaner. Refer to "13.5.9 Air Cleaner" .
  20. To prepare the transmission, power take-off and turbocharger:
    1. Follow the manufacturer's recommendations for prolonged storage to store the transmission.
    2. Follow the manufacturer's recommendations for prolonged storage to store the power take-off.
    3. Since turbocharger bearings are pressure lubricated through the external oil line leading from the oil filter adaptor while the engine is operating, no further attention is required. However, the turbocharger air inlet and turbine outlet connections should be sealed off with moisture resistant tape.
    4. NOTICE:

      Do not apply oil, grease or any wax base compound to the flywheel. The cast iron will absorb these substances, which can sweat out during operation and cause the clutch to slip.‪

  21. Apply a non-friction rust preventive compound to all exposed engine parts. If convenient, apply the rust preventive compound to the engine flywheel. If not, disengage the clutch mechanism to prevent the clutch disc from sticking to the flywheel.
  22. Drain the engine cooling system. Refer to "13.5.4 Cooling System" .
  23. Drain the preservative oil from the engine crankcase. Reinstall and tighten the 3/4 in.-14 square, magnetic drain plug to 45-56 N·m (33-41 lb·ft) torque.
  24. Remove and clean the battery and battery cables with a baking soda-water solution and rinse with fresh water. Do not allow the soda solution to enter the battery.
  25. Add distilled water to the electrolyte (if necessary) and fully charge the battery.

    NOTICE:

    Never store a battery in a place below 0°C (32°F).‪

  26. Store the battery in a cool, dry place. Keep the battery fully charged and check the level and specific gravity of the electrolyte regularly.
  27. Insert heavy paper strips between the pulleys and drive belts to prevent sticking.
  28. Seal all engine openings including the exhaust outlet, with moisture resistant tape. Use cardboard, plywood or metal covers where practical.
  29. Clean and dry the exterior painted surfaces of the engine and spray with a suitable liquid automobile body wax, a synthetic resin varnish or a rust preventive compound.
  30. Protect the engine with a good weather-resistant tarpaulin and store it under cover, preferably in a dry building which can be heated during the winter months.

    Note: Plastic may be used for indoor storage.

Section 14.1.4
Outdoor Storage (30 Days or Less)

In some cases outdoor storage may be unavoidable.‪

Note: Outdoor storage of engines is not recommended.

If units must be kept out-of-doors. Refer to "14.1.5 Outdoor Storage (More Than 30 Days)" .‪

NOTICE:

Do NOT use plastic sheeting for outdoor storage. Plastic is fine for indoor storage. When used outdoors, however, enough moisture can condense on the inside of the plastic to rust ferrous metal surfaces and pit aluminum surfaces. If a unit is stored outside for any extended period of time, severe corrosion damage can result.‪

Protect units with quality, weather-resistant tarpaulins (or other suitable covers) arranged to provide for air circulation.‪

The stored engine should be inspected periodically. If there are any indications of rust or corrosion, corrective steps must be taken to prevent damage to the engine parts.‪

Section 14.1.5
