 (2) At the track 2 position set the main eccentric bearing to the zero datum position as follows:
 (Ref. Fig. 521/TASK 27-51-00-991-071)
 (a)
 Remove and discard the lockwire from the nuts (57) installed on the failsafe hooks.

 (b)
 Loosen the nuts (57). NOTE : These are loosened to give easier movement when the

____ eccentric bearings are adjusted.

 (c)

 H. Set the Main Eccentric Bearings of the Inboard Flap to the Zero Datum Position
 (Ref. Fig. 521/TASK 27-51-00-991-071, 524/TASK 27-51-00-991-074) NOTE : The main eccentric bearings are spherical bearings installed in
____ the flap attachment fittings at the flap carriages.
 At track 1, an eccentric bush (86) is installed in the bearing (87). A pin on the eccentric bush (86) engages with the toothplate (85). The bearing (87) is at zero datum when the pin on the eccentric bush (86) is at the position shown (Ref. Fig. 524/TASK 27-51-00-991-074)

 At track 2, red paint marks on the bearing and on the fitting show
 the zero datum position. The bearing is at the zero datum position
 when the red paint marks are aligned.
 (Ref. Fig. 521/TASK 27-51-00-991-071)

 Adjust the bearings at one position then the other in small
 increments.
