 C. Adjustment Procedure
 (1)
 Carefully close the Bulk cargo-compartment door (Ref. TASK 52-30-00-860-008).

 (2)
 Make sure that the skin offset between the Bulk cargo-compartment door and the fuselage contour is correct (Ref. TASK 52-33-11-820-001).

 (3)
 Make sure that the Bulk cargo-compartment door closes easily.

 (4)
 Adjust the position of the forward and/or aft latch spigot as follows:

 (a) Measure the clearance Z between the barrel locks of the locking mechanism and the latch spigot.
 NOTE : The clearance Z must be min. 0.10 mm (0.0039 in.) .
____
 (b)
 If the clearance Z is not correct, adjust the position of the latch spigot with the related serrated plate (Ref. TASK 52-33-11-820-001).

 (c)
 TORQUE the nuts (10) and (28) to between 0.35 and 0.45 m.daN

 (30.97 and 39.82 lbf.in).

 (d)
 TORQUE the nuts (11) and (29) to between 0.70 and 0.80 m.daN

 (61.94 and 70.79 lbf.in).
 (5) Adjust the proximity switch 50WV as follows:
 (a) Measure the distance X between the target plate and bracket surface.
 NOTE : The distance X must be between 44.2 mm (1.7401 in.) and
____ 44.8 mm (1.7637 in.).
 (b)
 If the distance X is not correct, loosen the nut (35) and adjust the proximity target (36) until the distance is correct.

 (c)
 Tighten the nut (35) and safety it with the new tab washer (34).

 (d)
 Install the proximity sensor (25) with the safety washer (23) and the nut (24) to the bracket of the aft latch spigot (27).

 (e)
 Safety the nut (24) and the safety washer (23) with lockwire, corrosion-resistant steel dia 0.6 mm (0.2362 in.).

 (f)
 Connect the connector of the cable loom (26) to the proximity sensor (25).

 (6) Do an operational test to make sure that the function of the proximity switch 50WV is correct (Ref. TASK 52-71-00-710-001).
