How to safety wire forks?

[Bryan Cotton]

Hey guys,
Anybody have a link to a tutorial or pics on how to safety an AN486/MS27975 fork, like we have at our rudder horns? All I can find are turnbuckles.

Castle nut and cotter pin? Or am I missing something?

There is a hole in the fork body, and a hole in the swaged on threaded end of the cable. I have a jam nut on, but it seems a shame not to use those holes to safety the fork sort of like a turnbuckle.

AFAIK the small hole in the fork body is simply for visual indication to ensure the screw threads are deep enough into the body (like the control push-rod ends have.) I don't believe safety wire is necessary here. There really shouldn't be any sort of rotation that could allow the rudder cable to unscrew from the fork once it's secured to the rudder horn. Unless of course the cable itself starts break and unravel, but then you have bigger problems that safety wire probably won't help.

Isn't the hole in the fork body a witness hole? I thought it was there just to insure that you have inserted the threaded end of the cable deep enough into the fork.

Safety wiring forks........?

Bob Meyers is correct.......the hole in the fork is a "witness" hole........you thread the piece into the fork until it closes off the hole......and so you are not going to get a piece of safety wire through the hole.

In other words if you can see through the hole you didn't thread it in far enough. The hole is NOT meant for safety wire.

The same for rod end bearings.
