Now, with the Rotor disassembled, the Rotor can be eval-
uated. Inspect the Rotor for any noticeable wear. Also,
inspect the Bearings and surfaces for wear or damage
(Figures 24-27).
Note:
There is one segment that has an additional pin. This is to
ensure that the Rotor Cover can only be installed one way.
If the Cover and/or Rotor Bearings need to be replaced,
remove using the Slide Hammer Bearing Puller (P/N
651037-008)
Prior to reinstalling the Bearings, apply a light coat
of Cyberbond Titan 7769 Metal Bonder or equiva-
lent inside the Bore of Rotor and Cover. Using an
Arbor Press, press the Bearing into the Cover
(or Rotor) until the Bearing bottoms out in Cover
(or Rotor) Bore (Figure 25). When pressing the Bearing,
only press the Bearing outer diameter – NOT THE
INNER DIAMETER. Make sure the Rotor Body is
supported internally and not resting on the segments.
Note:
When using an Arbor Press, ensure the pilot portion of the
top punch fits inside the diameter of the Bearing.
Once the Bearing has been successfully installed into the
Cover/Rotor, ensure that the inner race of the Bearing
spins freely.

Check for Wear
To remove the Blade Bearing Assembly, remove the M5
Screw from the bottom of the Bearing Assembly (Figure
27). Ensure that the Blade Assembly spins freely and
independently. If Bearing Assemblies will be installed, it is
recommended to clean the assembly with a spray solvent.
If Bearings are replaced, be sure to apply a light coating
of Loctite 242 to the M5 Screw and Lockwasher. When
reinstalling the Blade Assembly M5 Screw, torque to
60 in/lbs.
Note:
Ensure that the screw is completely tightened in the mating
hole and that the pin does not spin while tightening.
Also be sure that the bearings spin freely of each other after tightening
is complete.
