I used Dr. Evil's video suite to tear apart and rebuild my 901 transaxle. Super good, but no discussion about what to expect for proper diff case rotation torque without 1-5 gear stack installed. I pulled the diff and put it in a plastic bag, cleaned the case, and put new seals in. I did not think to check when disassembling.
Diff is open type, side gears spin fine inside diff case. But when I twist both hubs in the same directlon, it takes a lot of effort. I'm guess-timating 30 ft-lb. I don't think this makes sense, but I don't actually know. I am concerned that a previous owner installed the diff wrong. But, the bearings don't have damage that I can see, so I don't have other evidence pointing to incorrect build.
Any advice on how to tell if appropriate drag for bearings?
Thanks
