Any suggestions on what pinion/spur gear to use?

Every 2 runs the spur gear gets crushed/flattened/ chipped / destroyed...
You are using a spur gear cover, correct? That's a pretty stout motor but the spur/pinion should easily be able to handle it. Mesh should be set with just a titch of play between the pinion and spur. Not too much, to little.
