Disassembly

Fan Mounting Disc Removal and Inspection

1. Place the Fan Drive in a vise and clamp the Journal
Bracket tight.
Applying 90-120 PSI air pressure to the Fan Drive
air inlet. This will aid in removal of the FMFD.
2. Loosen the Jack Bolt (left hand thread) by turning
it counter-clockwise using a T55 Torx Plus Bit.
Use caution when handling the prybar on the Fan
Mounting Disc. Permanent damage may occur if
not properly supported. Best results are achieved
with a flat blade tool like a Wonder Bar
that has a handle.
In CCW rotation applications, a jam nut will be
installed over the threads of the jack bolt. This
nut must be removed (left hand thread) before
loosening the jack bolt.
