I'm looking for ring and pinion gears for my ac 816 backhoe, any help would be great it's a rockwell rear end. Ring gear has 37 teeth, pinion has 7 teeth.

Are any Case industrial/utility tractor rear end parts compatible? Case used Rockwell in their wheeled loaders.

Case backhoes - 680E, 680G and 680H use the same Rockwell rear ends. Dynahoe as well, this Rockwell rear end was quite popular in the 70's and 80's. Even if some had a slightly different ratio, you can still put them in as long as you match the pinion and ring gears.
