Ball Diff Tool

[Siclick33 37]

Can anyone recommend me a driver for adjusting ball diffs? Is there a Tamiya tool for this?

The bolt head has quite a wide slot, and all of my long thin screwdrivers have thin tips that end up with everything getting chewed up. The drivers I have that are beefy enough to fit the head, won’t fit into the drive cup.

I’m having a hard time adjusting it, as I can’t tell if my screwdriver has seated correctly. I’m hoping someone has come across this before, before I go out and buy a hundred different screwdrivers!

Which chassis and differential are you referring to?

For instance I have been adjusting my Manta Ray ball diff with a rather normal 7mm box wrench, the one I install and remove wheels with.

BBX.

It needs a screwdriver.

What size is the screw?

Can it be swapped for a cap screw, and use an Allen driver?
