What's the diff ?

[Supermario]

I've always enjoyed the assembly of the rc axles and differentials since getting in the hobby. Brings a smile to my face working with the tiny microscopic stuff we play with. Heres why......

My next project at my real job. 4 final drives to swap out with exchange and I'm rebuilding both diffs due to no exchange available for this machine. I love this work way more than underground equipment which is all tight and awkwardly built.
Axle assembly weighs 15,000lbs . Just the diff is 2,000lbs. I'll post more pics once I get the diff out and on the stand. Oh, and these are out of a 992K loader.
