Mugen MBX Differential Service out of balance spur gear repair NON concentric MBX5 MBX6 MBX7 MBX8

I got this Mugen MBX6 in an ebay lot. I wanted to make sure the diffs had fluid so wouldn't burn up gears. My Mugen was a partial truggy upgrade and the original owner had changed the spur gear from 46 teeth to 51 teeth to match the larger tires. The problem was he didn't do it right leaving the spur gear out of balance. He tried using the plastic bag trick. All I had to do was drill and countersink the carrier to M4. Now I know the differentials are done correct I don't have to worry about burning up gears.

Great video as always! Have you ever tried a head mount for your camera? That way you can do the work with two hands, and we can enjoy watching you work!
