What 12mm hex's properly fit the Axial stub axles and drive pins?

[ProjectSCX10]

I just put a no slop locker in my stock scx10 axles. But there is still a fair amount of slop between the hex hub and the pin on the axle? I could ghetto rig it with tape or something to fix it :lmao: But I would rather buy some tighter fitting hubs or fix it in a bulletproof way. (suggestions?) :ror:

Re: 12mm Aluminum Hex Hub SLOP. How to fix?

I wish I knew a long term solution to the problem. All three of my Crawlers exhibit some degree of play between the hex and pin if you really torque the tires back and forth with your hands and brute force. Although, the rears feel ATV spooled tight when just turning them normaly by hand. Running Felsenfest spools.


It's a side effect of the steel pin being torqued back and forth against the soft aluminum hex. Some say the small grub screw is supposed to help hold the hex in place, but I don't think it's large enough, or able to be torqued down effectively enough.

Lets turn this into a "What hex's properly fit the Axial stub axles and drive pins?" thread.

I know that STRC aluminum replacements for a Slash, don't fit very well.

Who's running the J-fab 8mm hex's, and how do you like them?

If your snapping the stock hex pins then contact Gunnar for some stronger pins.

Resist the urge to overtorque the wheel nuts, it just puts more stress on the drive pin.

Yeah my spools are very tight and have no slop (not sure of the brand, stripped them off a used truck), but as soon as the hex goes on I have play. I tighter fitting hex is ultimately what I'm looking for. Good tips though!

Traxxas #1985 5x8mm teflon washers between the bearing and the pin. Just a couple each side.

I use these:

TowerHobbies.com | ASC25714 25714 Associated Washer 8x5mm (20)

I know they call them washers, but trust me,
they are thin shims.

You can use them to take up slack everwhere on an SCX.
The axles, diff gears, trany, anywhere a bearing or shaft has slop.

They are hard steel, and wont ware out like the teflon shims do.

I think they mean the rotational slop, not the side to side.

Are u guys using plastic hexes? I use the aluminum ones with a set-screw and them suckers don't move anywhere.

 

[foproy]

i actually use a set of traxxas hexes and they work great.

I have an assortment of washers and I know where/how to use them. They slop I'm talking about is radially, not in and out.

Maybe this is just one of those things telling me that I'm hard on equipment...

humm....

Yeah I'm referring to rotational slop. The hex moves slightly on the pin. No matter now tight my set screw is, it's still there.
