a.
Check the EFTC for positive lock pressure by applying moderate thumb pressure on the catch
toward the cable, attempting to lift the catch open.
b.
If the catch can be moved 1/16 of an inch the internal cable positive lock is improperly set.
c.
Recheck the actuator for the 2 ½-inch dimension as described above. If actuator is found suitable,
then cable assembly collar is set incorrectly and is defective, remove cable from service.
d.
If the catch cannot be moved 1/16 of an inch under moderate thumb pressure, and catch returns to
seated position (dot and arrow aligned), then EFTC is properly locked.
e.
Check that actuator arm swings freely through the platform rail indents with no interference from the
hex head bolts (replaced by round head bolts IAW FM 4.20-102) or other parts of platform. This
includes the upswing of arm to horizontal locked position by spring lever in actuator body.
f.
Check for proper operation of the EFTC by removing the actuator body from the EFTA mounting
brackets after removing the actuator pins.
g.
Carefully remove the actuator arm-locking pin and slowly rotate arm through its full range of motion.
Check that the catch in the latch was fully opened.
h.
Push on the latch retainer hook end, collapsing the linkage, and confirm link assembly cam rolls out
of latch freely. Reengage cam into latch, rotate linkage by thumb pressure to closed position and
relock actuator arm with locking pin.
NOTE
To prevent damage to cable and to prevent improper locking of latch,
reinsert cam and then rotate latch linkage to closed position before
relocking actuator arm.
11. Periodically check if the four adjusting collar setscrews are tight.
12. Repair each individual component as described in WP 0013 00 through WP 0019 00.
REPLACE
1. Replace damaged or missing EFTC parts only as authorized by the RPSTL, WP 0068 00 – WP 0073 00.
