2. The spur gear diff melts around the balls.
I've built tons of ball diffs in the past and used the same run in procedure with the Cat. The diff action was lovely and smooth and there was no slip (rotating by hand). But as soon as it is under load from the motor, after a couple of minutes, I can feel the slip in the transmission and sure enough, the spur diff is hot as hell and if I'm too late in stopping, a sticky plastic mess.
Any advice on what others are doing would be appreciated.

My spur gear has melted around the balls too. I was running a 10t motor but think the slipper was too tight
