I think it is good measure to check the heat of the differential casing after a few laps when the pinion and crownwheel are freshly mounted : when the casing gets very hot, something is wrong : or the parts are bad or they are mounted not correctly
There are at least 2 manufactures of the TR parts, I forgot about the names. As far as I know, used original parts are running cooler than some of the aftermarked parts. How was the noise of the diff? Did you notice the smell during the first laps?

I would love to here the FOT experience in breaking in new differential gears. What has worked well for you in the past?  

Last weekend, I was running the TR3 at Hallett with a brand new 4.55 gear set and it failed. I probably got 30 laps total in 4 sessions on track. I did not think to follow any set break in procedure with the gears and I am wondering if that is why they failed. 

I am interested in the lists experience with brand new or new old stock ring and pinion break in. 

Here is a pic of the failed set.
