(1) Use an applicable measurement method and:
(a)
Do a check for radial and axial play at the spherical bearings
(3) in the tie-rod (10):
-if you find radial and/or axial play more than the tolerances then you must replace the tie-rod (10) (Ref. TASK 21-61-00-300-001).
(b)
Do a check for radial and axial play at the spherical bearings
(4) and (6) in the bracket (15):
-if you find radial and/or axial play more than the tolerances then you must replace the bracket (15).
(c)
Do a check for radial and axial play at the spherical bearing (11):
-if you find radial and/or axial play more than the tolerances then you must replace the air inlet actuator eye-end (Ref. CMM 215312).
Subtask 21-61-51-220-052
B. In-Service Wear Limits
(1) Use applicable measurement equipment and measure the outside diameter (OD) of the bolt (16) and the inside diameter (ID) of the bushings (2).
NOTE : If any of the components are 'out of limits' then you must
____
replace them.
-for items (2) (Ref. CMM 215312).
