Ok. Wait do I need a spacial screw driver or go on the underside of the pilot?
The photo you posted, above, shows a hex-nut type of fastener. Thus, hex wrench, or a very small adjustable open-end wrench should loosen/remove that hex-nut shown in your photo. A "screw driver" will not fit/work.
Good news after waiting a while I got the correct tool my K4s has a o gauge coupler
