remove the spacer shim to make it easier to remove the fan
blade. The platforms between the blades make the airflow
smooth. The fan retaining flange and retaining ring holds the
fan blade spacer shims and platforms.
You read this information engraved under the root of the fan
blade:
* Part number
* Serial number
* Momentum weight.
When you remove or replace fan blades, record the position
and the serial number of the blades. That lets you do these
tasks:
* Install the blades you removed in the same position to keep
the engine in balance
* Calculate the spare blades position and the momentum
weight correction when you replace blades.
Balance Weight Screws
You balance an engine with balance weight screws. You install
the balance weight screws on the rear spinner.
Offset Holes
The offset holes let you install the spinner cones and the fan
retaining flange in only one correct angular position. Spherical
indents show the offset holes. There are offset bolt holes or
threads on these components:
* Spinner Front Cone
* Spinner Rear Cone
* Fan Retaining Flange
* Fan disk.
Training Information Point
You must remove the spinner front cone to remove the spinner
rear cone. You remove the spinner rear cone, fan retaining
flange and the retaining ring to get access to the fan blades. You
must remove the adjacent platforms and the fan blade spacer
shim to remove a fan blade.
