The rubber portion of clutch often bonds to the metal discs.        I would not try to separate them by force .                                        Other methods might work, but, I have not tried them.

The clutch is premium feature for KB-3 that KB-1 and KB-1A did not have originally, but, one that could be added later. . It is also possible to remove the clutch and use a sheer pin so by using the same parts as a KB-1 or KB-1A used.

Thanks Louis, I seen a slot machined across the
prop bore, down below the rubber cog a ways,
that I thought might be a shear pin groove, but it
looked to be cut square, instead of rounded like
most shear pin grooves.
I guess I won’t know unless I get the rubber “guts”
out of the prop.
I prefer the conventional shear pin set up on the
“no thrills” version.

Prepare to be boarded!
