S 424-021-C00
CAUTION: MAKE SURE THAT BENDS IN THE CABLE ARE NOT LESS THAN SIX INCHES
_______ (152 MM) RADIUS DURING THE REMOVAL. DO THIS WHEN YOU INSTALL THE CABLE THROUGH THE SIX O'CLOCK STRUT. SMALL RADIUS BENDS CAN CAUSE PERMANENT DAMAGE TO THE CABLE.
(1) With the MEC end of the cable retracted, supply the cable through the junction plate at the six o'clock strut.
NOTE:____The MEC end of the cable is the longer end. This is measured from the two bolt flange that is attached to the cable.
S 424-022-C00
(2)
Carefully put the cable down the six o'clock strut until the fixed flange touches against the junction plate.
S 434-023-C00
(3)
Attach the flange to the junction plate with two bolts and two nuts.
(a)
Lightly lubricate the bolt threads with grease.
