I checked a couple diffs , none of those numbers show, there was a lot of different manufactures of these gear sets. What does show is 35 6 , which is 6 teeth on the pinion ,35 ring, works out to 5:83 to 1 . I would count the teeth and make sure about the ratio first The list I posted are the bearing numbers I use for my machines.
This thread is about a Bombi , which has a T 16 style diff but smaller than the T16 in: J5/Muskeg/Sw48 and 252. So I would take these numbers on this thread with a grain of salt .
J5 Bombardier
