(1) Apply a layer of SEALANTS (Material No. 09-018) or SEALANTS (Material No. 09-019) to the shank of the bolt (28).
(2) Install the locking plate (30) and the locking ring (29) with the bolt (28).
(3) Safety the bolt (28) with MISCELLANEOUS (Material No. 19-010).
(4) Apply a layer of STORAGE PRESERVATION (Material No. 15-007) to the bolt (28), the locking ring (29) and the locking plate (30).

G. Friction Check of the Position of the Top, Aft Vertical-Roller at the Track (Ref. Fig. 402/TASK 27-84-61-991-003-A, 403/TASK 27-84-61-991-004)
(1) Attach a spring gage to the applicable track (1).
NOTE : During this check keep the spring gage in the line-of-travel
____
of the track (1).
(2)
Use the spring gage to move the track (1) from its fully extended position to the fully retracted position. Monitor the spring gage and make a record of the maximum value shown.
(3)
Use the spring gage to extend the track (1) to its fully extended position:
-
if the spring gage pulls the track (1), make a record of the maximum value shown
-
if the track (1) extends by its weight and the spring gage holds it back, make a record of the minimum value shown.
(4)
Calculate the friction load as follows:
-
for two maximum values, the friction load is the sum of the two values
-
for one maximum value and one minimum value, the friction load is the difference of the two values.
(5)
With the track (1) held against the two, top, vertical-rollers (32), move the track (1) through its full range of travel. Make sure that where the bottom, aft, vertical-roller (32) and the track (1) do not touch, the clearance (DIM. Y) is not more than 0.20 mm (0.0078 in.).
(6)
Adjust the top, aft, vertical-roller (32), if:
-the friction load is more than 6.22 daN (13.9831 lbf) and/or
-the clearance is more than 0.20 mm (0.0078 in.). R
