Procedure for Restoring to Service an Engine that Has Been in Extended Storage - Ops

If an engine has been in extended storage, prepare it for service as follows:

  1. Remove the covers and tape from all 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 reconnect the lines to their proper positions.
  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. Flush any soluble oil rust inhibitor (if used) in the cooling system.
  5. Remove the paper strips from between the pulleys and drive belts.
  6. Fill the crankcase to the proper level with the required grade of lubricating oil. Use a pressure lubricator to insure all bearings and rocker shafts are lubricated.
  7. Fill the fuel tank with the required fuel.
  8. Close all drain cocks and fill the engine cooling system with clean, soft water and required inhibitors. If the engine is to be exposed to freezing temperatures, install genuine Detroit Power Cool antifreeze or an equivalent ethylene glycol-base or propylene glycol-base antifreeze solution which provides required freeze, boil over, and inhibitor protection. Coolant Selections and Maintenance
  9. Install and connect the battery. Make sure the average specific gravity of the battery is 1.260 or higher. Charge the battery, if necessary.
  10. Service the air cleaner, if required.
  11. Transmission: Follow the manufacturer's recommendations covering the return of the transmission to service.
  12. Power Take-Off: If equipped, follow the manufacturer's recommendations covering the return of the power take-off to service.
  13. Turbocharger: Remove the covers from the turbocharger air inlet and turbine outlet connections. Reconnect piping as required. Pre-lube the turbocharger center bearing housing. Lubrication System Checks
  14. Fill the cooling system. Cooling System Fill Procedure
  15. After all preparations are completed, start the engine.
  16. Check for trouble codes.
    Note: The small amount of rust preventive 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, allow it to reach normal operating temperature.
    1. If there are no codes, perform a parked regeneration.
    2. If there are codes, repair what is necessary then perform a parked regeneration.
