Subtask 21-52-41-210-051
A. Visual Inspection of the Spherical Bearings in the Support Rods and Bracket
(1) On the support rods (71), (72a), (72b), (73), (74), (75), (77), (78), (79), (80), (81), (82) and (83):
(a) Use an applicable measurement method and do a check for radial and axial play at the spherical bearings (1).
R R R R 1_ For the 'adjustable rod ends',- if you find more than 0.05 mm (0.0019 in.) radial play or more than 0.2 mm (0.0078 in.) axial play in a spherical bearing (1) then you must replace the related rod eye-end (Ref. TASK 21-52-00-300-001).
R R R R R 2_ For the 'fixed rod ends',- if you find more than 0.05 mm (0.0019 in.) radial play or more than 0.2 mm (0.0078 in.) axial play in a spherical bearing (1) then you must replace the related support rod tube (Ref. TASK 21-52-00-300-001).
(2) Use an applicable measurement method and do a check for radial and axial play at the spherical bearing (7) in the bracket (106).
(a) If you find more than 0.05 mm (0.0019 in.) radial play or more than 0.2 mm (0.0078 in.) axial play in the spherical bearing (7) then you must replace it.
Subtask 21-52-41-220-050
B. In-Service Wear Limits
(1) Use applicable measurement equipment and measure the outside diameter (OD) of the bushing (98) and the inside diameter (ID) of the shouldered bushing (3).
NOTE : If any of the components are 'out of limits' then you must____ replace them, - for item (3) (Ref. TASK 21-52-00-300-001).
