DRY TYPE BEARINGS
2.
Check dry type rod end bearings as follows:
a.
Check visually for frayed fabric between inner
and outer races. If fraying extends more than
1/8 inch inside races, replace bearing.
b.
Teflon sticking to spherical ball is acceptable.
c.
Move bearing radially. If looseness is more
than 0.007 inch, replace bearing.
d.
Move bearing axially. If looseness is more
than 0.010 inch, replace bearing.
e.
Rotate bearing. If bearing is hard to turn,
replace bearing.
NOTE
High rotational forces cause high
starting forces within the flight control
system.
