You put it on there, and turn the security torx bolt out.
When I did cage work on mine, all those torx & security torx in the cage were frozen.
I broke a bunch of torx bits, and was at my wits end when I grabbed a big pipe wrench.
It worked like a charm, and I wish I had started with it.
Especially for the guy that says it'll strip it, nope, it's grabbing the outside of the bolt.
If you can get the bolt to start turning with a pipe wrench, then you still have factory minty fresh torx internal to use to turn it the rest of the way out.
The heads of the security torx on the A-B spreader stick out proud of the tube, there's plenty of room to get a pipe wrench on there, and if it didn't work I wouldn't say anything.
