Direct Drive to Diff E Revo Build

You will still need a roller bearing on the pinion side. Two bearings are needed for proper input shaft support. I was wondering what teh clearance is between teh pinion and the bearing near it. If there is enough clearance there to put a CF or stainless washer there, that would work. Maybe a narrower roller bearing would provide the needed clearance.

How it's setup now, the front pinion tries to push into the front diff, while the rear pinion tries to pull out of the diff.

Maybe just use CF on the load bearing side and a Ceramic Nitride bearing on the free wheeling side of the pinion. Think that would work? It sounds good.

I currently have 3 - .2mm shims there right now. It makes the mesh just right.

You will need at least 1.5mm CF wafer to act as a decent thrust bearing. If there is any way to run a narrower bearing there, you could add a thrust washer and that would most likely work.

If the design will allow for the bearings to be placed up against each other you may be able to make enough room for the cf washer. I have a pair of the hybrid diff cases at work, I will have to take one apart and see how it looks, even though Sike needs to dissassemble the diff again to replace the bearings.
