4. Procedure
Subtask 21-51-41-210-051-A

A. Visual Inspection of the Spherical Bearings in the Support-Rod and Bracket Assembly
(1) On the support-rod (1):
(a) Use an applicable measurement method and do a check for radial and axial play at the spherical bearings (2).
(b) If you find more than 0.05 mm (0.0020 in.) radial play or more than 0.2 mm (0.0079 in.) axial play in a spherical bearing (2) then you must replace the applicable rod eye-end (Ref. AMM TASK 21-51-00-300-001).
(2) On the bracket assembly (12):
(a) Use an applicable measurement method and do a check for radial and axial play at the spherical bearings (2).
(b) If you find more than 0.05 mm (0.0020 in.) radial play or more than 0.2 mm (0.0079 in.) axial play in a spherical bearing (2) then you must replace the bracket assembly (12).

B. In-Service Wear Limits
(1) Use an applicable measurement equipment and measure the outer diameter of the bushings (6) and the inner diameter of the shouldered bushings (4).

If the values of the components are 'out of limits' then you must replace them:
For shouldered bushings (4) (Ref. AMM TASK 21-51-00-300-001).

C. In-Service Wear Limits
(1) Use an applicable measurement equipment and measure the outer diameter of the bolts (5) and the inner diameter of the bushings (6).

If the values of the components are 'out of limits' then you must replace them.

D. In-Service Wear Limits
(1) Use an applicable measurement equipment and measure the outer diameter of the bolts (5) and the inner diameter of the shouldered bushings (3).

If the values of the components are 'out of limits' then you must replace them:
For shouldered bushings (3) (Ref. AMM TASK 21-51-00-300-001).
