Question 111Motor Plants - 1st Asst/Chief

The correct answer is D) Disassemble the entire unit, clean all components, replace any defective gaskets and use the proper lubricants where required. This is the correct approach because excessive sludge buildup in the device indicates a need for a thorough disassembly, cleaning, and replacement of any worn or damaged components. Merely removing and cleaning the disc stack (option A) or steam cleaning in place (option C) would not adequately address the root cause of the sludge buildup. Disassembling the entire unit and replacing any defective gaskets, in addition to cleaning all components and using the proper lubricants, is the comprehensive approach required to rectify the situation. The other options, while potentially addressing some aspects of the problem, do not encompass the full scope of actions necessary to properly resolve the excessive sludge buildup.
