Cen Nemesis XL Brushless Conversion

On a side note, I've never shimmed a diff before. I've found plenty of info on shimming the pinion shaft but nothing on how to shim the sun and planetary gears. I'm using the nemesis diffs which are beefy but I want to make sure I don't neglect them because of that.

Shimming- all shimming is the same. You want to add shims until there is almost no movement, just a tiny bit, a paper width of movement. If there is no movement it's too tight, and more than just a hair of movement is too loose.

Add shims where?

With the diff assembled if there is any in/out play in the diff cups you need to shim behind the sun gears to take that play out.

With the diff unassembled you can drop in a sun gear and see where it hits the planetarys. If you feel the mesh could be tightened then shim behind the planetarys.

Ok, so behind the sun gear ontop of the rubber seal?
That's what I thought but I was worried about the metal shim against the rubber seal.
Thank you very much!!
