I have CAT Engine 3516C has frequent failure in the air shut off groups both sides (R&H). This failure simply described as while the engine is running in normal condition the gate of the air shut off turned off without any detection because of uncompleted closing. The engine remains running with one side air inlet causing high exhaust temperature to the engine.I disassembled the air shut off found the latch mechanism between the electronic actuator and the gate is worn out.I brought a vibration engineer to ensure the vibration within acceptable range. He emphasis that there is unacceptable vibration only on the air shut off group whearas the rest part of the engine is within vibration limit. However, the vibration engineer told me it is resonance vibration and need to be corrected. Would you please told me in how to rectify the situation?
