I picked up a ball differential that came without install direction (of course :/). In the package are two soft rubber O-rings. What is the proper install procedure for the O-rings? Being of a soft rubber type, they appear to be for tension or torque adjustment rather than just spacers as with a metal shim. And what shaft adjustments or positioning, if any, are correct for proper function?
Thanks,

The “o” rings go between the thumbwheel and left diff plate, it adjusts the slip/action of the diff so you can adjust it to give good traction on any surface

that grub screw is 2mm… try a jewellers screwdriver set, that’s one place you’ll get a allen key that small, or if your local hardware store has em singly, mya be your best bet…:smiley2:

Thank you again. Finally got it with a 1.5 from my jewelers set and a pair of visegrips — it was stuck! LOL

Only use one O ring dude….. and give us a report on your sucess with the diff, if you have any problems, just give one of us a holla…

i lost the grub screw from my gpm ball diff and i got some replacements from a r/c plane shop.
only cost me $1.50 for three of them but they are a bit too long for the hole.
when adjusting/tightening the diff whats the best setting for different surfaces? i think i’m running mine a bit to loose at the moment.

Well, this was not a good day for much of anything — especially not to be working on the new diff!!
Got to breaking down the new diff to install the delrin gear and ….. the danged little c-clamp decided to take a prolonged vacation to parts unknown and to never be seen again. :dead: Guess I’ll spend a good deal of the next couple days scouring the local hardware stores to try to find a replacement. I already know they don’t carry metric screws or nuts that small. :8ball: -

I know tamiya carry them in bags of 10 and should only set you back a couple of dollars.

those c-clips give me the utter s***s… my carpet in my room has eaten at least five of the little buggers… so easy to lose as they fly off when being removed:angry:

Thats why i buy about 10 at a time from fastener stores….
The pilot shaft on the engine of my Nitro 1/10 has a c clip on the end, and if it comes off often the roller bearing comes out too and zooms off at a million miles an hour into a big patch of vegetation…..$22 just for the little roller bearing hurts….

funny how the smallest parts fly off into the largest areas of grass/shag carpet/etc…

Try a big-ass magnet 🙂
Won’t work on all parts but I find it handy on occasion, enough so that I’m considering making a rare-earth magnet “broom” 🙂 -
August 16, 2004 at 11:04 pm #54885
some parts such as stainless steel and non ferrous metals/composites are not attacted to magnets….

fortunately spring steel is magnetically attractive. i always have a big magnet right on the diff when removing the e clip. you should have one on your old stock diff (if you have one).
jamie told me to set your diff up so it slips just a little on take off. like a poor mans traction control, have it so the diff slips before the tyres do.:8ball: -

They don’t call the “jesus clips” for nothing 😉
You can also buy proper plier for handling them that reduces the loss factor to a much more sane rate 😉
