Hello all. Just took a new set of MTH crossing gates out of the box and installed them on the layout. One of them starts to go down then bobbles, I took it apart to find the vertical plastic gear in the gate stripped. The main one in the pole is brass. You can see in the one pic I enlarged how the gear is wallowed out so it won't contact the brass gear in the pole. No adjustments were made or needed on the up or down adjustment screws on the back. Here is a pic of the part I need. Any help would be appreciated. They are out of warranty, I already checked, since they sat in the box for almost 2 years.
