Poor Little Cone Style

I would still argue that while they are good units, the cone style is not torque sensing.. Those groves on the cones serve the same purpose as the groves in a syncro ring... def not "threaded" and not threaded into the case at all. The spring preload is ALL that keeps the cones pushed into the taper of the housing. There could be a small amount of force from the spider gears pushing away from each other too I guess. There are NO SPRINGS in a clutch style, but there do have two concave wave type plates in the clutch pack, to provide some preload. Most cone styles I have seen that fail, do so as a result of the cross pin wallowing out the case.
