Details regarding the internal modifications are as follows:
The idea is to create something similar to a ratchet using the internal teeth of the clutch. This would be for application on flywheels, for example, to protect the motors a bit from excess wheel momentum at the end of a match.
I’ve made up a quick example by filing the teeth on the inside of a clutch. One side of the each tooth is ramped, the other has been made more a shear vertical. This is a fairly crude job, but it should give an example of what I mean.
In addition to these photo’s here’s a quick video to demonstrate the clutch sliping much easier in one direction than in the other.
