Clutch splines worn

[jonjohnson]

Anyone have an idea as to what would do this to the splines on the flywheel disc on a south bend?

Well for some reason the picture isn't showing up. But the splines on the first disc against the flywheel are worn extremely thin , almost gone. Its a 4200 pressure plate and 12 ceramic button solid discs. The splines on the second disc are fine , no wear at all
