(10) Do a visual inspection of the spherical bearing of the MLG rear pintle pin:
(a)
Look at the sealant that covers the bearing assembly for breaks or cracks. Broken or cracked sealant is an indication of movement or loose items.
(b)
Do an inspection of the bearing and its retaining nut for signs of movement.
(c)
Do an inspection of the bearing retaining bolt for signs of movement and make sure it is not loose.
(d)
If you find signs of movement of the bearing, do a detailed inspection of the bearing assembly (Ref. CMM 32-12-25).

(b)
Make sure that the internal surfaces of the fixed bushes are clean.
(c)
Put the sleeve (15) in position on the rear pintle pin (20) and make sure that:
-
it will fully engage
-
it moves freely.
(d)
Remove the sleeve (15) from the rear pintle pin (20).
(e)
Put the sleeve (15) in position in the fixed bush and make sure that it moves freely.
(f)
Remove the sleeve (15) from the fixed bush.
(3)
Apply a thin layer of COMMON GREASE (Material No. 04-004) or COMMON GREASE (Material No. 04-022) to the internal surfaces of the fixed bushes.
(4)
Put the sleeve (15) in position in the fixed bush and make sure that:
-
it moves freely in the fixed bush
-
it is installed in the fully aft position.
(5)
Lubricate the new O-ring (31) with COMMON GREASE (Material No. 04-004) or COMMON GREASE (Material No. 04-022).
(6)
Apply a thin layer of COMMON GREASE (Material No. 04-004) or COMMON GREASE (Material No. 04-022) to the internal surface of the spherical bearing.
(7)
Install the new O-ring (31) in the internal groove of the spherical bearing.
(8)
Use the TOOL-PINTLE BEARING ALIGNMENT (MLG) (98D57004009000) to align the spherical bearing in the forward pintle mounting.
