I had a non hardened pinion with a plastic spur for a couple of months with very little wear. One night at racing my mesh slipped a bit and melted the spur. My only spare spur was a steel one, so I decided to use it for the last race which is only 5 minutes. After 4 minutes the pinion had no teeth left at all and my car had no drive.
