Custom Gearbox : Looking for some guidance

[Chir]

Greetings!

I'm very new to this hobby, and I have a passion for doing things I've never done before. I've recently taken on a project of restoring a Nikko Dictator and I want to do some custom work.

I'm about to use some terms that I'm not 100% comfortable with, so if I misuse them, please bear with me. I'll get there, I promise!

I've got a Traxxas 10280A Differential that I'm trying to put into a gearbox that I'm designed. I want to keep the same formfactor as the original Dictator Gearbox. I know I'll need to replace all the gears to match the diff, but I'm getting tripped up by what is some most likely something really simple.

I know that the diff is going to spin in the gearbox. What I'm not sure is, the (boss?) part the the drive cups attach to -- should that sit directly on the gearbox, or should it ride on a bearing.

If it helps -- this is the diff I'm working with:

When I build my custom gearbox, do I need to put a bearing around the black part (boss?), or does that silver part act as a bushing and sit right on the gearbox itself?

I know, I know... If I can't answer that, I probably shouldn't be doing this... BUT I REALLY, REALLY WANT TO!

Thanks for insight!

Looking at the Maxx Slash exoloded view, a bearing goes over the aluminum boss there. Not on yhe black output shaft.

Well, dang .. that was pretty obvious, wasn't it? Thank you so much for the help... I'm embarrassed to admit how much time I have in to figuring that out.

No worries. Any time you're doing something custom, you can almost always find exploded views for whatever RC you're working on. Some are better than others, but typically they're a big help.

Looking forward to seeing this project come together. So please share your progress
