Radiation-based framework is additionally sectioned into electronic gateway imaging device (EPID), cone bar CT, Fan shaft
, and others.
The initial system installed provides condition monitoring for two large 315kW fan sets and a single 90kW fan set, referencing the electric motor, power transmission coupling and main fan shaft
bearing on each.

THE SUPPEN STOP SNAPS THE HOLLOW ALUMINUM FAN SHAFT
If I can find the fan shaft
and pinion gear (which should have the rocker arms still attached) it will make the complete rebuild a little easier.
The toroidal bearing accommodates the thermal expansion of the fan shaft
, reducing friction, temperature, vibration, and power consumption while supporting higher fan speeds.
A straightforward device (like a central station air-handling unit) can be cleaned up; leak tested; receive a replacement fan shaft
, bearings, control valves, and damper actuators; and be viable for many years.
For Configuration 1 the motor needed to be raised to reach the keyway of the fan shaft
. This was done by mounting two additional cross beams directly under the motor.
The STC for Pratt & Whitney's CFM56-3 engine fan and booster includes three alternative parts, the fan disk, booster spool and fan shaft
. It certifies each part with FAA Chapter 5 life limits equal to the original type certificate holder.
Because the truck did not have a central hydraulic system, an extra pulley was installed on the fan shaft
for a belt-driven hydraulic source.
