I'm trying to figure out the torque capacity of the original ring and pinion used in our coaches.
The AAM/GM independent fronts had a 4643 ft lb ratting and the Dana 70's were rated 8000 ft lb's. These are max short duration ratings, the continuous rating for the Dana 70 is 2000 ft lb's but the IFS isn't rated as continuous. Does anyone know if there is a designation, ie Dana, Rockwell, Spicer used so I might find the information?
On another note, would anyone have an idea how much a differential would be de-rated buy running it backward, pulling vs pushing?

I'd much rather use something readily available in my swap so it can be more easily duplicated if desired. But the final product must be robust enough for the application.

Thanks for any advice,
Hal
