4. Inspect the fan mounting disc for wear or damage.

Learning Objectives:
• Describe the steps of safely removing and inspecting the fan mounting disc.

• Recognize signs of wear or damage to the fan mounting disc.

NOTE:
Applying 80-120 PSI [5.44 - 8.16 bar] air pressure to the fan drive air inlet will aid in removal of the FMFD.
