(b)
Remove and discard the cotter pin (4). Remove the nut (3) and the washer (5) from the lockbolt (1).

(c)
Remove the lockbolt (1) and the washer (7) from the forward pintle (2). If it is damaged, discard the washer (7).
(d)
Make sure that the lockbolt (1) is not bent or damaged. Replace a bent or damaged lockbolt (1).
(e)
Install a new or not damaged washer (7), the lockbolt (1), the washer (5) and the nut (3). Make sure the lockbolt (1) goes through the lugs on the pintle pin (6) with the head inboard.
(f)
TORQUE the nut (3) to 0.5 m.daN (44.24 lbf.in).
(g)
Safety the nut (3) with a new cotter pin (4). If the hole for the cotter pin (4) does not align, loosen the nut (3) sufficiently to align the hole.
NOTE : After the cotter pin is installed, a maximum end float of
____ 0.25 mm (0.0098 in.) of the lockbolt (1) is permitted.
(h)
Apply SEALANTS (Material No. 09-025) or SEALANTS (Material No. 09-002) to the lockbolt (1), the nut (3), the cotter pin (4) and the washers (5) and (7).
(i)
Apply a layer of STRUCTURE PAINTS (Material No. 16-021) or STRUCTURE PAINTS (Material No. 16-016) on all the sealant.
(j)
Lubricate the spherical bearing (18) through the greasers (17) (Ref. TASK 12-22-32-640-001).

C. Detailed Visual Inspection of the Forward Pintle Pin and Spherical
Bearing
(1) If the lockbolt (1) is missing, do the steps that follow:
(a)
Remove the MLG Leg Assembly (Ref. TASK 32-11-11-000-001).
(b)
Examine the pintle pin (6) for damage. Replace a damaged pintle pin (6).
(c)
Do an eddy current or dye penetrant test on the lugs of the pintle pin (6) (Ref. CMM 200000). Make sure that there are no cracks around the holes of the lockbolt (1). Replace a cracked pintle pin (6).

(d)
Examine the pintle pin (6) bushes in the forward pintle (2) for signs of damage.
(e)
Make sure that the lockbolt (1) bushes are correctly positioned in the forward pintle (2). Examine the bushes and make sure that they are not damaged.
(2)
Examine the spherical bearing (18):
(a)
Push the pintle pin (6) into the spherical bearing (18).
(b)
Use the pintle pin (6) to move the spherical bearing (18) around its center axis. Make sure that the spherical bearing (18) moves freely with hand pressure only.
(c)
Record the condition of the spherical bearing (18) and send the data to the Design Authority. This is so that, the relation between a tight spherical bearing (18) and a missing lockbolt (1) can be monitored.
(d)
Remove the pintle pin (6) from the spherical bearing (18).
(e)
Remove the greasers (17) from the spherical bearing (18).
(f)
Fully clean the greasers (17) with a MISCELLANEOUS (Material No. 19-003) made moist with CLEANING AGENTS (Material No. 11-026).
(g)
Install the greasers (17) in the spherical bearing (18).
(h)
Lubricate the spherical bearing (18) through the greasers (17) (Ref. TASK 12-22-32-640-001). Lubricate until clean grease comes out of the bore of the spherical bearing (18).
(i)
Push the pintle pin (6) into the spherical bearing (18).
(j)
Use the pintle pin (6) to move the spherical bearing (18) around its center axis. Make sure that the spherical bearing (18) moves freely with hand pressure only.
(k)
If the spherical bearing does not move, refer to the Design Authority for an approved repair procedure.
(l)
Remove the pintle pin (6) from the spherical bearing (18).
