Tub drain removal

: I have a Kohler bathtub with a twist n close drain stopper that has rusted. I want to replace it but cant figure out how to remove the old one. I removed the knurled knob on top of the stopper but instead of finding a screw I found an unslotted, smooth pin that the cover spins around. The cleanout flush plate says WATCO and I assume that the drain and flush plate came as a kit, but maybe not. I have a strainer wrench but cant get the cover off! Any help would be appreciated.look around the edge of stopper there should be a small allen screw.

Any help would be appreciated.: look around the edge of stopper there should be a : small allen screw.I failed to mention that there are no set screws visable. Granted, there is not much room to see how the stopper is assembled but Im wondering if there is a nut on the bottom of the brass plunger/pin since nothing is apparent from the top. I sure dont want to pull out the tub to get to it if thats the case. The tub is built in on a concrete slab.

Im thinking about cutting the shaft that goes up and down with a hack saw blade, if there is enough room to get it under the stopper cover. Any other ideas?

Any other ideas?Well at the moment I dont know what else to say: The three types Ive encounter are: 1- screw slot on the top 2-allen hole in top of pin 3-set screw or allen under stopper on cylinder that slides.it will be quite a chore to hacksaw this. have you thought of drilling a hole down into pin and useing a screw extractor or easy out as some people call them. please let me know what you find , I would still check that thing again with mirror.

What I discovered was a spring clip on the bottom of the brass plunger so it was inserted from the top and clipped on the bottom. Great design, huh? Thanks for the help.
