Good find Jim; that does look like the same gear. One weird thing is the reference "Color: 1.98mm Hole", which is repeated 4 times in the listing. What hole are they referring to I wonder?? 
I got my second gate repaired today as well. This one only took about 1/2 hour. Exact same problem, split plastic gear. I am batting 2 for 2 now!
Rod
One of my crossing gate arms is stuck.
