The one that seized had grease in it but not much. the two andymark sent us during the build season had a lot of grease in them and never had any problems.

Emphasis on the "yank". We did this during testing while waiting for a replacement, and getting it off was pretty difficult.

While it sometimes works, treat this as a last resort. The one we had seized again on another gear about five minutes after we took the first seized gear out, and then a third seized ten minutes after we removed the second. My theory is that it wasn't happy with the high speed we were driving it with, especially with such a low torque (in a badly-thought-out shooter). It was one of the old ones which are partially black plastic, and the newer all-metal one was fine, as is our all-metal replacement. I hope the seizing problem was a problem with the black design and has been fixed in the metal one.
