MBE 900 – Section 14.1 Preparing Engine for Storage

Section 14.1
Preparing Engine for Storage

When an engine is to be stored for a period of time, special precautions should be taken to protect the interior and exterior of the engine.‪

Section 14.1.1
Cleaning the Engine

Please follow the equipment manufacturer's operating instructions for using high-pressure cleaning equipment.‪

Information on suitable cleaning and protective products is available from any authorized dealer.‪

NOTICE:
To prevent damage to engine components during the cleaning process, keep the water moving at all times. Never direct water onto electrical components, plug connectors, seals or flexible hoses.‪

Comply with the minimum working distance between the high-pressure nozzle and the surface being cleaned:‪

• Approximately 700 mm (28 in.) for circular pattern jets
• Approximately 300 mm (12 in.) for 25-degree flat jets and dirt cutters

Section 14.1.2
Cleaning the Cooling System

Clean the cooling system as follows:‪

Note: Collect the used coolant, cleaning solutions, and washing liquids. Dispose of them in accordance with applicable laws regarding the protection of the environment.

NOTICE:
Clean at moderate pressures only; otherwise the fins of the radiator grille could be damaged.‪

EYE INJURY ‪
To avoid injury from flying debris when using compressed air, wear adequate eye protection (face shield or safety goggles) and do not exceed 276 kPa (40 psi) air pressure.‪

1. Remove debris (dust, insects, etc.) from the fins of the radiator grille by blowing them through with compressed air or spraying them out with water. Work from the rear of the radiator (in the opposite direction of the normal cooling air flow).

   PERSONAL INJURY ‪
   To avoid injury from scalding, drain the radiator when the engine and coolant are cool.‪

2. Drain the coolant when the engine is cold.
3. If the HVAC unit is connected to the cooling system, open the regulating valves all the way.

Section 14.1.3
Degreasing the Cooling System

Degrease the cooling system as follows:‪

1. Fill the cooling system with a 5% solution (1.6 ounces per quart of water—50 grams per liter) of a mildly alkaline cleaning agent, such as sodium carbonate.

   PERSONAL INJURY ‪
   Diesel engine exhaust and some of its constituents are known to the State of California to cause cancer, birth defects, and other reproductive harm.‪ Always start and operate an engine in a well ventilated area. If operating an engine in an enclosed area, vent the exhaust to the outside. Do not modify or tamper with the exhaust system or emission control system.

2. Run the engine at moderate speed until the thermostat starts to open, at an operating temperature of approximately 176°F (80°C). Then run it for about five minutes longer. Shut down the engine and allow it to cool to approximately 122°F (50°C).

   HOT COOLANT ‪
   To avoid scalding from the expulsion of hot coolant, never remove the cooling system pressure cap while the engine is at operating temperature. Wear adequate protective clothing (face shield, rubber gloves, apron, and boots). Remove the cap slowly to relieve pressure.‪

3. Drain all the cleaning solution.
4. Flush the cleaning solution from the cooling system.
   1. Immediately after draining the cleaning solution, flush the system with clean water.
   2. Once the clean water has drained, fill the system again with clean water.
   3. Run the engine. Allow the engine to warm up to approximately 176°F (80°C), and then run it about five minutes longer.
   4. Drain the hot water.
5. Fill the cooling system with new coolant.

Section 14.1.4
Storage

Required protective measures for the MBE 900 engine depend on the following:‪

• The length of time that the engine will be out of service
• The climate and conditions where the engine is stored

After cleaning, engines should be placed in a dry, well-ventilated area.‪

In all cases, protect the engine against direct exposure to moisture (rain/splash water).‪

If the engine is to be out of service for 12 months or less, anticorrosion measures are not necessary, provided that the place of storage are dry and well-ventilated as described above.‪

If the engine is to be out of service for over 12 months, or under extraordinary storage or transportation conditions, then special protective measures are necessary.‪

Section 14.1.5
Extended Storage (More Than 12 months)

To prepare an engine for extended storage (more than 12 months), follow this procedure:‪

1. Drain the cooling system. Refer to "13.1.6 Coolant Flushing and Changing" .
2. Flush with clean, soft water. Refer to "13.1.6 Coolant Flushing and Changing" .
3. Refill with clean, soft water and add a rust inhibitor to the cooling system. Refer to "5.3 Coolant" .
4. Circulate the coolant by operating the engine until normal operating temperature is reached.
5. Stop the engine.
6. Install new lubricating oil filters. Refer to "13.1.4 Engine Oil and Filter Changing" .
7. Fill the crankcase to the proper level with Tectyl® 390A preservative lubricating oil or an equivalent 30–weight preservative lubricating oil meeting MIL-L-21260C, Grade 2 specification. Tectyl® is a registered trademark of Daubert Chemical Company, Inc..
8. Drain the fuel tank.
9. Refill with enough clean No. 1 diesel fuel or pure kerosene to permit the engine to operate for about ten minutes. If it is not convenient to refill 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 of fuel lubricity.

   Note: In environments where microbe growth is a problem, a fungicide such as Biobor®JF (or equivalent) may be used. Biobor® is a registered trademark of United States Borax and Chemical Corporation.. 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.

10. Drain the fuel system.
11. Remove the fuel filters. Refer to "13.1.2 Fuel Pre-Filter Element Cleaning" and refer to "13.1.3 Main Fuel Filter Element Changing" .
12. Install new filters with No. 1 diesel fuel or pure kerosene. Refer to "13.1.2 Fuel Pre-Filter Element Cleaning" and refer to "13.1.3 Main Fuel Filter Element Changing" .

    PERSONAL INJURY ‪
    Diesel engine exhaust and some of its constituents are known to the State of California to cause cancer, birth defects, and other reproductive harm.‪ Always start and operate an engine in a well ventilated area. If operating an engine in an enclosed area, vent the exhaust to the outside. Do not modify or tamper with the exhaust system or emission control system.

13. Operate the engine for five minutes to circulate the clean fuel oil throughout the engine. Ensure the engine fuel system is full.
14. Disconnect the fuel return line and the inlet line at the primary filter and securely plug both lines to retain the fuel in the engine.
15. Service the air cleaner.
16. To prepare the transmission, power take-off and turbocharger:
    1. Follow OEM recommendations for prolonged storage to store the transmission.
    2. Follow OEM 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.

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

17. 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.

    NOTICE:

    Incomplete draining of the water pump may result in rusting of the impeller to the pump body during extended engine storage, especially if inadequate inhibitor was used in the remaining coolant. Damage from freezing temperatures may occur if the coolant remaining in the engine has insufficient antifreeze to prevent it from freezing and expanding. To ensure complete pump drainage, always remove the drain plug from the bottom of the pump before extended storage. If a coolant filter/inhibitor system hose is attached to the bottom of the pump, disconnect the hose and allow the pump to drain completely. Open the drain cock at the bottom of the filter. Do not reinstall the pump drain plug or filter hose or retighten the filter drain plug until the engine is put back into service.‪

18. Drain the engine cooling system. Refer to "13.1.6 Coolant Flushing and Changing" .
19. Drain the preservative oil from the engine crankcase.
20. Remove and clean the battery and battery cables with a baking soda-water solution and rinse with fresh water. Do not allow the baking soda solution to enter the battery.
21. Add distilled water to the electrolyte (if necessary) and fully charge the battery.

    NOTICE:
    To avoid possible battery damage caused by freezing, never store a battery in a place below 0°C (32°F).‪

22. Store the battery in a cool, dry place. Keep the battery fully charged and check the level and specific gravity of the electrolyte regularly.
23. Insert heavy paper strips between the pulleys and drive belts to prevent sticking.
24. Seal all engine openings including the exhaust outlet, with moisture resistant tape. Use cardboard, plywood, or metal covers where practical.
25. 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.
26. 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.
