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.

The thing with the cat is the diff is in the layshaft not the rear drum like your use to. If you hold the spur gear and the rear wheel the same side then turn the opposite wheel you'll thigten the diff as it sounds like it's running a little loose.
