    Engines inactive for over 180 days must have what accomplished?

    • Motor the engine to circulate the oil

    • Inspect the reservoirs to ensure they are full

    • Visually inspect compressor for corrosion

    • Preservation run and fuel system preservation

    Correct Answer
    A. Preservation run and fuel system preservation
    Explanation
    Engines that have been inactive for over 180 days need to undergo a preservation run and fuel system preservation. This is necessary to prevent any damage or deterioration to the engine and fuel system due to prolonged inactivity. The preservation run involves running the engine for a certain period of time to circulate the oil and ensure proper lubrication. Fuel system preservation involves taking measures to prevent the fuel system from getting contaminated or degraded during the inactive period. Both these steps are crucial to maintain the engine's functionality and prevent any issues when it is put back into operation.

    When can you consider a depreserved engine ready for service?

    • After motoring the engine and changing the filters

    • As soon as all depreservation fluid has been purged

    • Only after a ground check run of the engine has been performed

    • After visually inspecting the compressor and turbine for signs of corrosion

    Correct Answer
    A. Only after a ground check run of the engine has been performed
    Explanation
    The correct answer is "Only after a ground check run of the engine has been performed." This means that before considering a depreserved engine ready for service, it is necessary to conduct a ground check run of the engine. This ensures that the engine is in proper working condition and ready to be used. Motoring the engine, changing the filters, and visually inspecting the compressor and turbine for signs of corrosion may be important steps in the overall process, but they are not sufficient on their own to determine if the engine is ready for service.

    What is used to help remove moisture from an area where engines are stored?

    • Corrosion-preventative compound (CPC)

    • Corrosion-preventative mixture (CPM)

    • Cobalt chloride

    • Desiccants

    Correct Answer
    A. Desiccants
    Explanation
    Desiccants are used to help remove moisture from an area where engines are stored. Desiccants are substances that have a high affinity for water molecules and are able to absorb and hold moisture from the surrounding environment. By placing desiccants in the area where engines are stored, they can effectively reduce the moisture content in the air, preventing corrosion and damage to the engines. This makes desiccants an effective solution for maintaining the quality and longevity of engines in storage.
