B. Installation of the Datum Side-Rollers NOTE : This procedure is only necessary where all the side-rollers are
____
removed.
(1)
For tracks 5 and 11, prepare the aft datum side-roller (20) for electrical bonding (Ref. TASK 20-28-00-912-004).
(2)
For tracks 6, 7, 8, 9, 10 and 12, apply a thin layer of COMMON GREASE (Material No. 04-024) to the interface of the datum side-rollers (20) and the shims (23).
(3)
Apply a layer of SEALANTS (Material No. 09-018) or SEALANTS (Material No. 09-019) to the shanks of the bolts (21).
(4)
Put the necessary thickness of shims (23) and the aft datum side-roller (20) in position.
(5)
Install the shims (23) and the aft datum side-roller (20) with the washers (22) and the bolts (21).
(6)
For tracks 8 and 11, where applicable, safety the bolts (21) with MISCELLANEOUS (Material No. 19-010).
(7)
Apply a layer of STORAGE PRESERVATION (Material No. 15-007) to the bolts (21), the washers (22) and the shims (23).
(8)
Do the procedure again for the front datum side-roller (20).
(9)
If removed, install the applicable slat track (2) (Ref. TASK 27-84-62-400-001).
Subtask 27-84-62-420-052
C. Installation of One Side-Roller or a Pair on the Same Side
(1)
For tracks 5 and 11, prepare the side-roller(s) (20) for electrical bonding (Ref. TASK 20-28-00-912-004).
(2)
For tracks 6, 7, 8, 9, 10 and 12, apply a thin layer of COMMON GREASE (Material No. 04-024) to the interface of the side-roller(s) (20) and the shims (23).
(3)
Apply a layer of SEALANTS (Material No. 09-018) or SEALANTS (Material No. 09-019) to the shanks of the bolts (21).
(4)
Put the shims (23) and the side-roller(s) (20) in position.
(5)
Install the shims (23) and the side roller(s) (20) with the washers
(22) and the bolts (21).
Subtask 27-84-62-820-059
D. Adjustment of the Side Rollers
(1)
Move the applicable track (2) through its full range of travel and make sure that:
-
the side-roller(s) (20) touch the track (2) at some point of its travel
-
the points that touch do not stop the smooth travel of the track (2).
(2)
To adjust the side-roller(s):
(a)
Remove the bolts (21), the washers (22), the side-roller(s) (20) and the shims (23).
(b)
Adjust the thickness of the shims (23):
-
to reduce the friction, increase the thickness of the shims
(23)
-
to make sure that the side-roller(s) (20) touch the track (2) at some point of its travel, decrease the thickness of the shims (23) as necessary.
(3)
Install the shims (23) and the side-rollers (20) with the washers
(22) and bolts (21).
(4)
Do the procedure again, as necessary, until the side-roller(s) (20) adjustment is correct.
(5)
For tracks 8 and 11, where applicable, safety the bolts (21) with MISCELLANEOUS (Material No. 19-010).
(6)
Apply a layer of STORAGE PRESERVATION (Material No. 15-007) to the bolts (21), the washers (22) and the shims (23).
