__________ Subtask 21-61-52-860-056
A. Aircraft Maintenance Configuration
(1) Make sure that the applicable components are disassembled to do the inspection procedure.
4. Procedure
_________ (Ref. Fig. 602/TASK 21-61-52-991-009) Subtask 21-61-52-210-052
A. Visual Inspection of the Spherical Bearings NOTE : The tolerance for radial play in a spherical bearing is 0.05 mm
____ (0.0019 in.). The tolerance for axial play in a spherical bearing is 0.2 mm (0.0078 in.).
R 1EFF : 001-003, 051-054, 1 21-61-52Page 606 1 1 May 01/05 1 1 1CES 1 (1) Use an applicable measurement method and:
(a)
Do a check for radial and axial play at the spherical bearing (1):
-if you find radial and/or axial play more than the tolerances then you must replace the eye-end in the air-outlet flap actuator (Ref. CMM 215312).
(b)
Do a check for radial and axial play at the spherical bearings
(6) and (12):
-if you find radial and/or axial play more than the tolerances then you must replace the ram air outlet (Ref. TASK 21-61-52-000-003) and (Ref. TASK 21-61-52-400-003).
Subtask 21-61-52-220-052
B. In-Service Wear Limits
(1) Use applicable measurement equipment and measure the outside diameter (OD) of the bolt (7) 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 item (2) (Ref. CMM 215312).
