B. Locking Clip
(1) Proper use of Locking Clips
(a) Prior to safetying, both threaded terminals shall be screwed an equal distance into the
turnbuckle body and shall be screwed in at least so that not more than three threads of
any terminal are exposed outside of body.
(b) After the turnbuckle has been adjusted to its locking position, (with slot indicator groove on
terminals and slot indicator notch on body aligned) insert the end of locking clip into termi-
nal and body until the U-curved end of locking clip is over the hole and in the center of the
body.
(c) Press locking clip into hole until it’s fully seated (curved end of locking clip will expand and
latch in body slot).
(d) To check proper seating of locking clip, attempt to remove pressed “U” end from body with
fingers only.
Note: Both locking clips may be inserted in same hole of turnbuckle body or in
opposite holes of turnbuckle body. Locking clips are for one time use only
and shall not be re-used.
C. Rod Ends
Rod end assemblies are subject to a variety of environmental conditions and forms of deterioration
that ultimately may be easy to recognize such as a failed rod end. The not so readily visible types of
deterioration include wear, corrosion and/or distortion. The critical area on a female rod end is the
internal thread of the rod end.
(1) Inspecting
It will be necessary to remove the rod end from the corresponding control cable to properly
inspect it for internal wear and corrosion as this condition is usually not evident on the outer sur-
face of the rod end.
Note: Before removing rod ends with inspection holes, ensure the rod ends are properly
seated onto the control cable. The control cable must be installed beyond the
inspection hole. When removing rod ends without inspection holes, leave the jam
nut in its original position. Measure the distance from the face of the jam nut (side
which was tightened against the rod end) to the end of the control cable. This dis-
tance is referred to as the thread engagement depth. Rod ends with a hole diame-
ter of 0.190 inch or 0.250 inch must be threaded onto the control cable to a
minimum thread engagement depth of 0.312 inch.
(a) Examine all rod ends for proper depth installation and then remove the rod ends.
(b) Carefully examine the exterior of all rod ends for wear, corrosion, damage, and/or distor-
tion. Replace all rod ends having signs of wear, corrosion, damage, and/or distortion.
(c) Carefully examine all rod ends for internal wear, corrosion, damage, and/or distortion.
Replace all rod ends having signs of internal wear, corrosion, damage, and/or distortion.
(d) Carefully examine the threaded portion of rod end for damaged threads. Replace all rod
ends having signs of damage to the threads.
Note: If damaged threads or premature/excessive wear is found or suspected,
replace the rod end.
