White powder around the diff?

White powder around the diff? - 01.05.2012, 02:44 AM

After one or two runs of my brushless buggy, I found there was very fine white powder around large end cap and motor mound. It looked like a very thin coating of white paint.
Did it come from the slipper pad because of friction or it was just some unknown dust?
Dose this situation imply that it is too much slip for the pads?
The weather was cold out there. The temp of large end cap was just warm.

Do you have a picture?
What do you mean by large end cap?
I would guess you got a slipper diff or something in buggy.

Yes. I am talking about slipperenital on a converted buggy.
I have no picture because I cleaned up the slipperenital in the field.
If it were pad dust, I will try to tighten the wave springs to see how it goes.

I wouldn't sweat it too much - if it was dust from the slipper pads, it is likely just some break-in dust as you said it was only run a couple times. If you are happy with the slip level and the unit isn't excessively hot, then run it. More slip will equal faster wear(the Teflon bushing is the first and primary wear item), but don't be afraid to use it.
I run mine on the tight side for minimal wear, while protecting the drive train, but in slippery conditions or when the race is on, I tune it as needed to maximize my lap times.

Thanks Mike.
To give a more detailed description, I upload the pictures.
You will know what I am saying.
The gap between adjusting ring and pressure plate is around 2mm.
Perhaps, I can tighten it more.
