R (5) Do this test:
R NOTE : The rigging pins 98D52307525100 and 98D52307525200 are part of
____ R the ADJUSTMENT TOOL - CARGO DOORS (98D52307525000).
-------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
1. On each frame of the cargo door: R - install the rigging pin R 98D52307525200 into the rigging R hole below the locking shaft to R examine the upper dead center.
R - install the rigging pin R 98D52307525100 in the rigging R hole behind the safety shaft to
examine the lower dead center.
-make sure that the rigging pins are removed from the last frame.
2. On the cargo door:
-pull the locking handle away from the recess of the handle flap and measure the force
R necessary with a SPRING BALANCE R 20 DAN (48 LBF).
-turn the locking handle down to the UNLOCKED position and measure the force necessary
R with a SPRING BALANCE 20 DAN R (48 LBF).
3. On the control panel:
-set the selector to the CLOSE position and hold it.
