 (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).
