(1) Extend the drift pins on the open cargo door as follows:
(a) Press the roller lever of the interlock mechanism outboard to release the blockage of the latching shaft.
R (b) Move the door handle down to the locked position and push it into the recess of the door structure.
R R R (2) Install the PIN - RIGGING, CARGO COMPARTMENT DOOR (98D52308308000) (165) into the bearing assy (164) and the shaft lever (162).
R R R (3) If you cannot install the PIN - RIGGING, CARGO COMPARTMENT DOOR (165) into the shaft lever (162), adjust the length of the control rod (166) as follows:
R R (a) If necessary, cut and remove the lockwire from the safety devices (169).
(b) Loosen the upper and lower jam nuts (168).
R R (c) Turn the turnbuckle (167) until you can install the rigging pin (165) into shaft lever (162).
R R (d) Tighten the jam nuts (168) and safety them with the lockwire, MISCELLANEOUS (Material No. 19-010) on the safety devices (169).
(4) Measure the distance "U" between the end of the extended drift pins (160) and the edge members of the cargo door.
NOTE : The distance "U" must be between 34.7 mm (1.3661 in.) and 37.7____ mm (1.4842 in.).
(5) Move the door handle away from the door structure up to the 65 degree position.
(6) Make sure that the ends of the retracted drift pins are behind the skin edges of the cargo door.

F. Adjustment of the Interlock Mechanism
(Ref. Fig. 508/TASK 52-31-11-991-025)
(1)
Make sure that the door handle of the opened cargo door is in the fully UNLOCKED position.
(2)
Measure the gap "Z" between the stop assy (173) and the interlock cam
(171) of the latching shaft.
NOTE : The gap "Z" must be between 1.0 mm (0.0393 in.) and 1.4 mm
____
(0.0551 in.).
(3) Adjust the gap "Z" as follows:
(a)
If necessary, bent the tab washer (176) from the lock nut (175).
(b)
Loosen the lock nut (175) remove the stop bolt (174) from the interlock lever (172).
(c)
Replace the tab washer (176) and install it with the stop bolt
(174) and the lock nut (175) on the interlock lever (172).
(d)
Turn the stop bolt (174) in or out until the gap "Z" is correct.
(e)
Tighten the lock nut (175) correctly and safety it with the new tab washer (176).

E. Adjustment of the Drift Pin Mechanism
(Ref. Fig. 507A/TASK 52-31-11-991-012-B)
(1) Extend the drift pins on the open cargo door as follows:
(a)
Press the roller lever of the interlock mechanism outboard to release the blockage of the locking shaft.
(b)
Turn the locking handle up to the locked position and push it into the recess of the handle flap.

(2) Measure the offset "X" between center lines of the bellcrank lever
(53) and the extended drift pins.
NOTE : The offset between the parallel center lines must be between
____ 1.0 mm (0.0393 in.) and 1.5 mm (0.0590 in.).
(3) If the offset "X" is out of tolerance, adjust the length of the teleflex controls as follows:
(a)
Remove and discard the cotter pin (60) from the nut (59).
