Section 15.2
Restoring An Extended Storage Engine

Use the following procedure to restore an engine that has been in extended storage.‪

1. Remove the covers and tape from all of the openings of the engine, fuel tank and electrical equipment. Do not overlook the exhaust outlet.
2. Remove the plugs from the inlet and outlet fuel lines and connect the lines to their proper position.
3. Wash the exterior of the engine with fuel oil to remove the rust preventive. (Do NOT wash electrical components.)
4. Remove the rust preventive from the flywheel.
5. Remove the paper strips from between the pulleys and drive belts.
6. Fill the crankcase to the proper level, with the recommended grade of lubricating oil listed in Table "Recommended Engine Oil" . Use a pressure lubricator to insure all bearings and rocker shafts are oiled.

   * U.S. on-highway requirement.
   † Non-domestic and off-highway applications only.
   ‡ The cloud point should be -12°C (10°F) below the lowest expected fuel temperature to prevent clogging of fuel filters by crystals.
8. Close all of the drain cocks and fill the engine cooling system with clean soft water and proper inhibitors. Refer to "5.4 Coolant" . If the engine is to be exposed to freezing temperatures, fill the cooling system with an ethylene glycol base antifreeze solution. Refer to "14.6.4 Cooling System" .
9. Install and connect the battery. Ensure that the average specific gravity of the battery is 1.265 or higher. Charge the battery if necessary.
10. Perform the following steps for proper air cleaner restoration:
    1. Keep the air cleaner housing tight on the air intake pipe.
    2. Ensure the correct filter replacement is used.
    3. Keep the air cleaner properly assembled so the joints are strictly airtight.
    4. Repair any damage to the air cleaner or related parts immediately.
    5. Inspect and clean or replace the air cleaner elements as operating conditions warrant.
    6. Carefully inspect the entire system periodically. Enough dust-laden air will pass through an almost invisible crack or opening to eventually cause damage to an engine.

    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.‪

    7. If a foam or fabric air cleaner element soaked with sticky dirt-holding substance was previously installed, check for the presence of coated engine components. Remove and clean them with a suitable solvent, as required, and blow dry with compressed air.
11. Follow OEM recommendations covering the return of the transmission to service.
12. Follow OEM recommendations covering the return of the power take-off to service.
13. Remove the covers from the turbocharger air inlet and turbine outlet connections. Pre-lube the turbocharger.

    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.

14. After all of the preparations have been completed, start the engine. The small amount of rust preventive compound which remains in the fuel system will cause smoky exhaust for a few minutes.

    Note: Before subjecting the engine to a load or high speed, it is advisable to allow the engine to reach normal operating temperature. Then, monitor the DDEC Diagnostic Data Link for trouble codes. Refer to the Detroit Diesel Single ECM Troubleshooting Manual, (6SE497).
